Associação de obesidade sarcopênica, indicadores de composição corporal, de variabilidade da frequência cardíaca e de esforço no teste do degrau de seis minutos com a severidade da Síndrome da Apneia Obstrutiva do Sono: Um estudo transversal
(Universidade Federal do Pará, 2025-12-19) SOUZA, Leornado Brynne Ramos de; CRISP, Alex Harley; http://lattes.cnpq.br/1187580727139009; HTTPS://ORCID.ORG/0000-0003-4683-9576; NEVES, Laura Maria Tomazi; http://lattes.cnpq.br/4235603520707156; https://orcid.org/0000-0002-3115-2571
Introduction: Obstructive sleep apnea syndrome (OSAS) is the most common sleep- related respiratory disorder in the world, with different levels of severity. The literature indicates that increased body fat can increase energy expenditure, alter heart rate variability during sleep and wakefulness and affects the severity of the syndrome. Thus, there is a greater risk of muscle catabolism, negatively influencing cellular health, measured by the phase angle in bioelectrical impedance. However, few studies have expanded the assessment of body composition in relation to sarcopenic obesity in this population. In addition, the results of current research are also conflicting when analyzing the impacts of OSAS severity on metabolic and physical performance during stress tests. Objective: To investigate the association of indicators of body composition, heart rate variability, and stress in the six-minute step test with the severity of OSAS. Methods: Cross-sectional, quantitative study that took place between December 2023 and August 2024, with a single sample of 37 people diagnosed with OSAS, age 53,7 ± 13,8 years, minimum age 28 years and maximum age 78 years, confirmed by type 1 polysomnography. Data collection was performed in two phases: a) Rest, using bioelectrical impedance (Biodynamics BIA 450, Biodynamics Corporation, Washington, USA) to collect body composition data, indirect calorimetry (Quark CPET, Cosmed, Italy) to collect resting metabolic rate and time and frequency domain variables of heart rate variability using a heart rate monitor (SmartLab, HMMGroup, Germany); b) Exercise, using the 6-minute step test with a gas analyzer (Quark CPET, Cosmed, Italy) breath by breath to assess physical and metabolic effort. To determine data normality, the Shapiro-Wilk test was used, with normal data represented by mean and standard deviation and non-normal data represented by median and interquartile range. For multivariate data analysis, principal component analysis (PCA) was used, employing the varimax rotation algorithm to create the components. The reduced value of each component was used to perform a simple linear regression analysis. Results: Thirty-seven individuals with OSAS (54.05% men), BMI 31.1 ± 5.31 kg/m2 and AHI 31.3 (11.3-61.6) were evaluated. The PCA analysis created 6 principal components (PC), which are: 1st PC: body composition; 2nd PC: cellular health; 3rd PC: physical effort; 4th PC: ventilatory reasons; 5th PC: sympathovagal stimulation; 6th PC: sympathovagal stimulation (very low frequency). The body composition indicators component (BMI, neck circumference, resting metabolic rate, body resistance, and capacitance) was associated with higher AHI (F[3,32] = 3.05; p = 0.01), with an adjusted r2 value of 0.22. Conclusion: Body composition is associated with the severity of OSAS, while the components of cellular health, physical effort, ventilatory ratios, sympathovagal stimulation, and very low frequency sympathovagal stimulation were not associated with the severity of the syndrome.

(Universidade Federal do Pará, 2024-08-09) MORAES, Janine Brasil de Araújo; NEVES, Laura Maria Tomazi; http://lattes.cnpq.br/4235603520707156; HTTPS://ORCID.ORG/0000-0002-3115-2571; CARNEIRO, Saul Rassy Carneiro; http://lattes.cnpq.br/9162153771863939; https://orcid.org/0000-0002-6825-0239
Introduction: Introduction: Ageing can be accompanied by a progressive decline in muscle mass, strength and function. This resulting health condition is known as sarcopenia, a muscle disease that develops progressively and chronically. Age-related sarcopenia has several factors that accelerate this process and need to be identified and controlled in order to promote a good health prognosis and quality of life for the elderly population. Objective: To assess the association between sarcopenia and functional and quality of life indicators in elderly people treated at the geriatrics outpatient clinic of the João de Barros Barreto University Hospital (HUJBB). Methods: This is an observational, analytical, cross-sectional study carried out at the HUJBB geriatrics outpatient clinic. Sociodemographic and clinical assessments were carried out: sarcopenia assessment (SARC-Calf, handgrip strength assessment, Tetrapolar Electrical Bioimpedance (BIA) and Short Physical Performance Battery (SPPB)), functional indicators assessment (Barthel, quadriceps strength assessment, physical activity level assessment (IPAQ) and presence of falls in 60 days) and quality of life assessment (SF-12). The algorithm of the European Working Group on sarcopenia in the elderly (EWGSOP2) was used. Results: 129 participants were assessed (73% women, p = 0.001), with a mean age of 75.4 years and from the capital (80.6%). 57% were found to be at risk of sarcopenia, with a prevalence of sarcopenia of 27.1%. Handgrip strength (HGS) 18kg/f, skeletal muscle mass 18.3kg; SPPB 9 points; Barthel score 58.8% of independent participants; quadriceps strength 14kg/f; IPAQ 38.8% with a low level of physical activity and SF-12 37.7 points for the physical component and 48.2 points for the mental component. There was an association between appendicular skeletal muscle mass (ASMR) and calf circumference (WC), age, SARC-Calf, FPM and quality of life (physical component) for men (adjusted R2 0.42 and p<0.05), as well as sarcopenia, classified by ASMR, with BIA variables: body resistance, total body water in lean mass, lean mass and basal metabolic rate for men (adjusted R2 0.49 and p<0.05), and for women, intracellular water and total body water in body weight (adjusted R2 0.60 and p<0.05). Conclusion: This study concludes that WC, age, sarcopenia risk screening, HGS and quality of life were associated with MMEA measured by BIA. For the diagnosis of sarcopenia, there were different associations between the BIA markers when adjusted for gender.

Atividade bioelétrica dos músculos do assoalho pélvico durante o uso de educador vaginal inovador: estudo transversal
(Universidade Federal do Pará, 2022-11-08) DUARTE, Natália de Souza; MELO NETO, João Simão de; http://lattes.cnpq.br/1547661999153615; https://orcid.org/0000-0002-4681-8532
The pelvic floor needs an integral anatomical structure due to its multiple functions. Therefore, innovative equipment is needed to improve this structure. The aim of this study was to analyze the effects of using the innovative iGeni vaginal trainer on the bioelectrical activity of the pelvic floor muscles, in addition to analyzing the different hip positions and interference factors such as age group, childbirth, sexual activity, urinary incontinence and menopause. For this, a cross-sectional study was designed, composed of 30 women, who were evaluated using the following instruments: evaluation form, International Consultation On Incontinence Questionnaire - Short Form and surface electromyography. The collected findings were: RMS of the 5-second period of contraction, peak RMS values, area values, %MVC (RMS normalized by peak signal) and median frequency. These findings were compared without and with the use of iGeni, in anteversion, neutral and retroversion pelvic positions. The results showed that the use of iGeni increased the electromyographic activity of the pelvic floor muscles in the neutral position. Women in conditions of greater tendency to dysfunction of this musculature also benefited, increasing bioelectrical activity under specific conditions. It was then concluded that this innovative biofeedback equipment was effective in the greater recruitment of muscle fibers and that it has greater effectiveness in the neutral position of the hip, being able to be an effective ally in the training of this musculature.

Características do ambiente escolar associadas à prática de educação física e ao deslocamento ativo em adolescentes de Belém-PA: um estudo multinível
(Universidade Federal do Pará, 2025-02-26) SOUZA, Naicha Stefanie Félix; CRISP, Alex Harley; http://lattes.cnpq.br/1187580727139009; https://orcid.org/0000-0003-4683-9576
Understanding how school environment characteristics influence adolescent physical activity behaviors is essential for developing targeted interventions. The aim of this study was to investigate the associations between school environment characteristics and the levels of participation in Physical Education (PE) classes and active commuting to school. This is a cross sectional study with multistage sampling, involving 1,719 adolescents from 46 public and private high schools in the municipality of Belém, Pará. The time spent in PE classes and active commuting during the previous week was self-reported based on the National School Health Survey questionnaire. School environment characteristics were obtained through questionnaires completed by school administrators and researcher observation visits. Zero-inflated negative binomial regression models were used to address overdispersion and excess zeros in the data. The results indicated that the majority of students (55.0%) did not participate in practical PE classes, with only 37.6% reporting 30 minutes or more of activity per week. Regarding active commuting, approximately one-third of adolescents (34.6%) did not engage in this type of commuting. In the logit component of the adjusted models, factors associated with reduced odds of non-participation in PE classes included a higher number of PE teachers (OR = 0.79; 95% CI: 0.71–0.87), the presence of locker rooms (OR = 0.66; 95% CI: 0.54–0.83), and school accessibility (OR = 0.68; 95% CI: 0.54–0.86). For active commuting, the presence of sidewalks (OR = 1.34; 95% CI: 1.03–1.74) and bike racks (OR = 1.61; 95% CI: 1.26–2.05) increased the odds of non-engagement, while speed bumps (OR = 0.60; 95% CI: 0.43–0.82) reduced the odds of non-engagement. In conclusion, school environment characteristics have the potential to decrease non-adherence to practical PE classes among adolescents. However, active commuting behaviors may depend on factors beyond infrastructure, requiring further exploration.

Análise Psicométrica da Versão Brasileira da Pittsburgh Fatigability Scale (PFS-Brasil)
(Universidade Federal do Pará, 2024-04-24) SANTOS, Mayara do Socorro Brito dos; TORRES, Natáli Valim Oliver Bento; http://lattes.cnpq.br/1927198788019996; https://orcid.org/0000-0003-0978-211X
Introduction: Instruments with appropriate psychometric properties are essential for ensuring the quality of assessments and reassessments in clinical practice, guiding decision-making regarding rehabilitation procedures. The Pittsburgh Fatigability Scale, originally published in English, is the only validated scale for measuring perceived fatigability in older adults. Considering the importance of this tool, it is necessary to validate its translated version into Portuguese and adapt it to the specificities of the Brazilian context. Objective: To validate the Pittsburgh Fatigability Scale Brazilian Portuguese version (PFS-Brasil) by evaluating its validity in relation to measures of physical activity, physical performance, and cognitive performance. Methodology: The scale and physical and cognitive performance tests were used to assess 121 healthy older adults residing in the community. We conducted statistical analyses of the physical and mental subscales of the PFS-Brasil, utilizing the intraclass correlation coefficient (ICC) for reliability analysis, Cronbach's alpha for internal consistency evaluation, and Spearman's correlation for convergent validity. Furthermore, we examined agreement analysis and floor and ceiling effects. The Statistical Package for Social Sciences 25.0 was used for data analysis. Results: The analyses indicated that the physical and mental subscales exhibit satisfactory test-retest reliability, with ICC values for the physical subscale (0.84; 95% CI: 0.80-0.88) and the mental subscale (0.83; 95% CI: 0.78-0.87), in addition to high internal consistency (α = 0.84 and 0.82, respectively). These values are indicative of good inter-rater reliability, revealing a low probability of random and systematic error. Bland-Altman plots demonstrated good agreement for both subscales of the PFS-Brasil. For convergent validity, the higher physical score showed a moderate association, and the higher mental score showed a weak association with lower physical performance (6-minute walk tests and the Short Physical Performance Battery (SPPB) and lower levels of physical activity (International Physical Activity Questionnaire – IPAQ). Regarding cognitive performance, there was a weak association between the higher mental score and the average accuracy on the flanker test. No ceiling effects were observed in both subscales; however, the mental subscale exhibited a floor effect (n = 24%). Conclusion: This study demonstrated that the Brazilian version of the Pittsburgh Fatigability Scale is a valid, consistent, and reliable instrument for assessing perceived fatigability in older adults.

Atividade física, qualidade do sono e fatores associados à capacidade para o trabalho de fisioterapeutas da linha de frente contra a COVID-19
(Universidade Federal do Pará, 2021-06-28) MORAES, William Rafael Almeida; NEVES, Laura Maria Tomazi; http://lattes.cnpq.br/4235603520707156; https://orcid.org/0000-0002-3115-2571
INTRODUCTION: The COVID-19 pandemic highlighted the importance of physical therapy for the control and prevention of pulmonary and musculoskeletal complications, with emphasis on the specialty Respiratory Physical Therapy and Physical Therapy in Intensive Care. However, the physical and mental demands required for work on the front lines, as well as the changes in lifestyle in the face of the pandemic, may have negatively interfered with the physical therapists' ability to work. OBJECTIVE: To associate the level of physical activity, sleep quality, and demographic and occupational factors with the work ability of physical therapists on the front lines against COVID-19. METHODS: Analytical, cross-sectional and quantitative study. Brazilian physiotherapists working on the front lines against COVID-19 answered an online questionnaire that grouped four instruments: a) demographic, occupational and lifestyle data; b) the International Physical Activity Questionnaire (IPAQ); c) the Pittsburgh Sleep Quality Index (PSQI); d) the Work Ability Index (ICT). Data were analyzed and presented in descriptive statistics (absolute and relative values, mean, standard deviation) and associations between the ICT results and the independent variables, giving significance when p ≤ 0.05. The statistical software R version 4.0.0 was used. RESULTS: Answers were obtained from all regions of Brazil. There was no association between work ability and physical activity level, but inadequate work ability was associated with poor sleep quality (p < 0.001) and ICT and PSQI values showed a significant negative correlation (r = - 0.340; p < 0.001). In the adjusted analysis, work ability was associated with female gender (p = 0.018) and with a clinical diagnosis of previous COVID-19 (p < 0.001). CONCLUSION: In times of pandemic, reduced work ability is associated with poor sleep quality but not with physical activity level among frontline physical therapists against COVID-19. The results warn about the potential impact of sleep on the work of professionals who deal with the health of the population, highlighting the need for occupational health support strategies for physical therapists, especially in periods of public health crisis.

Leprosy can cause significant physical disabilities if not early diagnosed and treated. The diagnosis is essentially clinical, through dermatoneurological examination, including a subjective and low sensitivity manual muscle strength test. Household contacts of untreated patients are most at risk of developing the disease. Early diagnosis is essential for breaking the chain of transmission and preventing disability. In this context, the use of dynamometry provides objective data on handgrip strength through a simple and cost-effective clinical test, and with functional tests, could contribute to an early detection of peripheral nerve disorders. The aim of this study is to correlate handgrip strength and functionality data with biomarkers of Mycobacterium leprae infection among people affected by leprosy, their household contacts, and schoolchildren in endemic areas. The study was approved (report 5384136) and carried out in Imperatriz (MA), São Luís (MA) and Marituba (PA). Subjects diagnosed with leprosy, their household contacts and school contacts <15 years old were clinically examined and have biological samples collected for the detection of IgM-anti-PGL-I antibodies and for the molecular detection of M. leprae by means of RT-PCR. Strength was measured using a handheld dynamometer, while we used a scale and functional tests to assess functionality. A total of 179 subjects were included in the study, 94 females (52.51%), 67 cases of leprosy (28 new cases and 10 index cases) and 60 healthy household contacts (36.5 ±14.69 years) and 52 healthy schoolchildren from an endemic region. We found a significant prevalence of loss of muscle weakness (p=0.0003) in leprosy cases compared to healthy individuals. Healthy male subjects >15 years old had significantly higher mean values of grip strength and pinch strength (p<0.05) compared to male leprosy cases, except for the pulp pinch. Leprosy cases > 15 years old showed significant functional losses (p<0.05), evaluated by TFMJT and 9-PnB and a longer test time, when compared to the healthy group, mainly women. It was observed that leprosy cases had significantly more activity limitations when assessed on the SALSA scale (p<0.05). Subjects with changes in nerve palpation and decreased tactile sensitivity showed significantly more muscle weakness and functional loss (p<0.05). We found an inversely proportional correlation between anti-PGL-I IgM titers and muscle grip strength and pinch strength in individuals over 15 years of age (p<0.05). While muscle weakness was observed in most RT-PCR positive cases. Of the positive individuals for RT-PCR, 42.31% presented functional loss in the tests, showing a significantly longer time in the TFMJT (p=0.028). Those positive for RT-PCR presented significantly greater times in the block stacking (p=0.046) and feeding simulation (p=0.025) subtests. We observed muscle weakness in 28.75% and loss of function in 33.33% of subjects double positive for anti-PGL-I and RT-PCR. Therefore, these data show us that there may be motor and functional impairment in this population that is more vulnerable to the development of leprosy, where these tests can find disabilities, in addition to those of the traditional clinical evaluation.

Sensores inerciais: Uma alternativa objetiva para classificação baseada em evidências do Basquete em cadeira de rodas
(Universidade Federal do Pará, 2021-05-19) SÁ, Karina Santos Guedes de; SILVA, Anselmo de Athayde Costa e; http://lattes.cnpq.br/4794918582092514; https://orcid.org/0000-0001-5265-619X
The classification system for Paralympic sports has evolved with the improvement of evaluations, to make competitions fairer. With this, an international movement was developed to make the classification of athletes based on evidence. Such evidence can be obtained in different ways, such as tests and valid equipment for measures of variables related to classification. Thus, the main objective of this dissertation was to investigate the use of inertial sensors in the sportive classification process of wheelchair basketball. The dissertation was written in the aggregated model of articles and has two articles: a systematic review and an original study. In the systematic review, we observed that instruments such as kinematics, dynamometers and inertial sensors have been applied in the evidence- based classification in wheelchair sports, using variables such as strength, speed and acceleration to discriminate subjects from different classes. In our original study, we observed that: 1) higher class athletes performed performance tests in less time; 2) 16 variables showed moderate and strong significant correlations with the sports class; 3) the variables collected with the sensor positioned in the wheelchair presented a greater number of strong and moderate correlations with the sports class and; 4) the Illinois agility test showed more variables correlated with the sports class when compared to the maximum speed test of 20 meters and the anteroposterior axis of both sensors showed a greater number of variables correlated with the sports class. In summary, the inertial sensors seem suitable for assessing the sporting class. Finally, we believe that the use of technologies in the sports environment will grow more and it seems to be a path of no return, taking performance and competitions to other levels.

Determinantes de sarcopenia e fragilidade em pessoas com Parkinson no contexto amazônico
(Universidade Federal do Pará, 2025-03-26) SANTOS, Ana Carla de Matos; MONTEIRO, Elren Passos; http://lattes.cnpq.br/0920248966438368; https://orcid.org/0000-0001-7757-6620
Introduction: Aging is a natural process characterized by the progressive loss of tissue and organ function, increasing the predisposition to various diseases, including Parkinson's Disease (PD). Among the conditions associated with PD, sarcopenia and frailty stand out as relevant geriatric syndromes. Sarcopenia is defined by the progressive reduction of muscle mass, strength, and function, while frailty is characterized by greater vulnerability to stressors, impacting physiological reserve and functional capacity. Despite distinct concepts, both share pathophysiological mechanisms affecting muscle power, such as chronic inflammation, oxidative stress, and neuromuscular degeneration. The absence of accessible and standardized instruments for screening these geriatric syndromes in clinical settings represents a challenge, especially considering the applicability of these methods in different sociodemographic contexts, such as in the Amazon region. Objective: This study aimed to analyze the profile of sarcopenia and frailty, as well as possible associations with clinical parameters of PD and sociodemographic aspects in people with Parkinson's disease (PwP) living in the community of a state in the Amazon region. Methods: This is an observational and analytical study, including PwP over 40 years of age, of both sexes. Initially, an anamnesis was conducted to collect sociodemographic data, followed by using instruments such as SARC-Calf and Short Physical Performance Battery (SPPB) for sarcopenia screening, and Fried's Phenotype for frailty screening. Vertical power was analyzed using the My Jump 2 app, considering parameters such as jump height, flight time, take-off velocity, force, and power. For statistical analysis, Spearman's correlation coefficient was used to identify possible associations between sarcopenia and frailty with clinical and sociodemographic variables. Subsequently, logistic regression was conducted to assess whether body mass predicted sarcopenia. Regarding frailty, none of the predictors were significant. All analyses were performed using SPSS software (IBM, Greenville, SC), version 25.0. Results: A total of 24 people with Parkinson's disease (PwP) were evaluated, 83.3% of whom were male, with a mean age of 66.35 years, living with a spouse and children (37.5%). They were stratified into sarcopenic (29.2%) and non- sarcopenic (70.8%) groups. An association was observed between sarcopenia and body mass (OR = 1.438; CI = 1.045 – 1.980). Regarding frailty, the prevalence was lower than reported in the literature, possibly due to the small sample size. Conclusion: This study concluded that body mass was a risk predictor for sarcopenia in PwP, and that the sample profile was predominantly male, with a higher occurrence of falls in stage 2 of PD and a high prevalence of pre-frailty. Despite the absence of other significant predictors for sarcopenia and frailty, the findings highlight the need for clinical standardization and universal diagnostic criteria, considering regional sociodemographic aspects.

Resistance Training (RT) is a modality that has high applicability and efficiency in physical, clinical and functional contexts. The scientific advance in this modality, a series of recommendations for the manipulation of variables and dosage of RT emerged for different purposes and population. However, it is not clear how these RT prescription guidelines affect responsiveness, characterized like an individual's particular capacity for respond to/benefit from an intervention, for a given measure. Therefore, the aim of the study was to carry out a systematic review to investigate the effect of RT on the responsiveness of healthy adults, in variables of strength, power, functionality and muscle hypertrophy, based on the prevalence rate. Only randomized clinical trials, in English, indexed in the PubMed/MEDLINE, SCOPUS, EMBASE and SPORTDiscus databases, published until June 2021, were considered. The study was registered in the International Prospective Register of Systematic Reviews (PROSPERO), identified by the code CRD42021265378. After the study selection process, the risk of bias was analyzed using the ROB2 tool from Chrocrane. After the search strategy, 3033 studies were found and, through the screening process, 13 studies were selected for systematic analysis. As for the effectiveness of the RT, the prevalence range for non-responders individuals to muscle strength was 0% to 44%, for hypertrophy 0% and 84% and functionality 0 to 42%, while, for muscle power, only one study investigated the responsiveness rate and reported 37%. Therefore, it seems that alterations to muscle hypertrophy may be less sensitive to RT, compared to other variables. Larger RT volume tends to be more effective overall, however intensity may be a key factor in some cases. However, the principle of specificity can be the most important aspect to effectivity of TR in these variables of interest. Moreover, it is important to consider methodological and statistical aspects when analyzing outcomes in responsiveness.

A predição de uma ação transitiva é modulada pela valência emocional do objeto
(Universidade Federal do Pará, 2021-06-02) AZEVEDO, Priscila da Silva; CAMPOS, Anaelli Aparecida Nogueira; http://lattes.cnpq.br/1380793960958329; SAUNIER, Ghislain; http://lattes.cnpq.br/6254015055212071; https://orcid.org/0000-0002-0882-7788
Recent experimental evidences demonstrate that the action observation and action execution directed to objects (i.e., transitive action) shared similar motor areas. This action-perception network is involved in our ability to predict the sensory consequences of actions performed by others. Thus, the main objective of the present work was to evaluate the effect of an object's emotional valence on to the action prediction process. For this, 38 undergraduate students were recruited to watch reach-to-grasp videos directed of pleasant, unpleasant or neutral objects on a computer screen. Two visual conditions were included: occlusion (a black rectangle occluded the last 50% of the movement) and full vision. In total, 90 repetitions were performed (2 visual conditions x 3 valences x 15 repetitions). The experiment always started with the occlusion block. The participant's task consisted in predict the time-to-contact (TTC) between the hand and the object by pressing the space bar on the keyboard. Prediction errors were calculated based on the temporal difference (ms) between the participants' prediction of TTC and the contact times of our videos. An ANOVA for repeated measures (2 visual conditions x 3 valences) was used to compare the prediction errors. The Tukey post-hoc test was used to compare the significant effects (p <0.05). Our results suggest that the prediction of action is modulated by the emotional valence of the object. We found a valence effect with a greater temporal precision for AGR and NEU objects when compared to DES. There was no visual effect on action prediction. Finally, we observed that the visual condition only modulated the prediction of the action directed to AGR and NEU objects. To our knowledge, this is the first behavioral demonstration that the emotional valence of objects interferes within the action prediction process. These results may contribute in the future to the development of complementary protocols to traditional motor rehabilitation.

(Universidade Federal do Pará, 2021-12-09) DUARTE, Manuela Brito; CALLEGARI, Bianca; http://lattes.cnpq.br/0881363487176703; https://orcid.org/0000-0001-9151-3896
Article 1: Postural adjustments are triggered by the central nervous system in response to external disturbances and consist of anticipatory (APAs) or compensatory (CPAs) adjustments. APAs are muscle recruitment, associated or not with the displacement of the Center of Pressure, in advance of predictable disturbances. CPAs, on the other hand, are generated as a result of the imbalance, after the disturbance. Currently, the study of APA and CPA is restricted to research laboratories due to the need for specific equipment, difficult to handle and high cost. The objective of this project was to validate a mobile application (Momentum) for the evaluation of APAs and CPAs. Healthy young people were subjected to a predictable external disturbance produced by the impact of a pendulum. We used gold standard equipment to compare the results obtained by Momentum. Validation results, APA latency (APAonset), maximum peak (ACCpeaktime) and acceleration variation (ACCpeak) after impact and time to peak (ACCpeak) were the parameters that showed the strongest correlation indices. (r). In terms of reliability, Momentum had a very high correlation in APAonset and APAamp. In the CPA, only the ACCrange had an excellent correlation, the other parameters presented a reasonable to high correlation. In general, Momentum proved to be valid and reliable for evaluating APAs and CPAs. Article 2: New technologies mainly in the sports environment where performance and competitive power are essential, the use of inertial sensors for analysis and evaluation in sports stands out, as long as they are reliable to the gold standard evaluation equipment. The objective of this article was to validate the acceleration signals of the center of mass (COM) in the anticipatory and compensatory phase of the disturbance comparing the two equipments (Metamotion C and kinematics). Twenty healthy young men were exposed to the pendulum paradigm, which consisted of predictable anteroposterior disturbances provoked at the level of the shoulders. The validation results showed a significant linear correlation of all variables from moderate to large with r ≥ 0.5. Reliability between kinematics sessions was excellent (≥0.75). The APAonset variable presented a reasonable to high ICC, while the CPAtime showed an excellent correlation. The results show that Metamotion C proved to be reliable and valid in measuring COM acceleration in both APA and CPA.

After Paralympic insertion, sitting volleyball experienced a solid development and greater introduction of athletes in the sport, a fact that required a greater increase in intensity and frequency in training and competitions, contributing to increase competitiveness and the occurrence of injuries. The main objective of the present study is to identify the epidemiological aspects of sports injuries in seated volleyball athletes. The systematic review followed the declaration of Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and was registered in the International Prospective Register of Systematic Reviews (PROSPERO) platform. The search platforms selected for the research were: PubMed, BVS, SciELO, SPORTDiscus and Medline. The research included studies that presented: data on the profile of sports injuries in seated volleyball athletes; with a sample composed of competitive athletes at least 1 year old and over 18 years old; published between 1980 and 2020; in English, Spanish and Portuguese. Two independent reviewers applied the search strategy and assessed the methodological quality according to the STROBE and STROBE-SIIS statements. Duplicate removal was performed using EndNote software. After collecting eligible studies, data were expressed in tables, charts and a map. Finally, we found in the included studies a clinical incidence of 0.57 and prevalence of 54.1% of injuries, with a predominance of injuries in the upper limbs (53.8%), specifically in the shoulder (28.9%), by overload mechanism (58%), acute (66%), at the time of training (48%), resulting in absence (52%), severe (38%) and non- recurring (57%). Given this epidemiological profile, we suggest guidelines for preventive conduct, training planning and protection of the athlete's health.

Breast cancer is an aggressive and mutilating disease responsible for the highest number of deaths among women in Brazil. The mastectomy postoperative period leads to limitations of upper limb movement, particularly of ipsilateral side to the affected breast. This research aimed to investigate whether motor representations of upper limb are modulated after mastectomy surgery. For this, a hand laterality judgment experiment was carried out, in which the participant identified whether the images projected on a computer screen represented a right or left hand. Respecting the inclusion criteria, 17 women participated in the study, 9 with mastectomy with some limitations of upper limb movements, ipsilateral to the affected breast and 8 healthy women who underwent the same experiment, at the Laboratory for the Evaluation and Rehabilitation of Cardiovascular Dysfunctions, Oncology and Respiratory - LACOR (UFPA). The results showed a lower accuracy for mastectomized women when assessing the laterality of the ipsilateral hand to the affected breast compared to the control group, particularly for restricted biomechanically postures (i.e., palmar view and 90° lateral orientation). Such results suggest changes in the motor representations of the upper limb ipsilateral to the affected breast.

Efeito do exercício físico na força muscular, massa muscular e desempenho físico em pessoas sarcopenicas com câncer: uma revisão sistemática
(Universidade Federal do Pará, 2024-12-20) GUEDES, Laerte Jonatas Leray; NEVES, Laura Maria Tomazi; http://lattes.cnpq.br/4235603520707156; https://orcid.org/0000-0002-3115-2571
Cancer is the leading cause of secondary sarcopenia, representing a growing problem among people diagnosed with cancer. This condition is associated with unfavorable outcomes both in relation to disease progression and to the various types of cancer treatment. Physical exercise is recommended by several guidelines for cancer patients. However, the guidelines do not present specific recommendations for sarcopenia, and few systematic reviews have explored this topic. In addition, the effect of physical exercise on improving sarcopenia (muscle strength, muscle mass and physical performance) in cancer patients is not yet fully elucidated. Objective: To verify the effect of physical exercise on muscle strength, muscle mass and physical performance in sarcopenic people with cancer. Materials and methods: The study is a systematic review, we used the acronym PICOS as the inclusion criterion, population: adult patients diagnosed with cancer and diagnosed with sarcopenia; Intervention: physical exercise alone or associated with other interventions; control: patients in usual care, without treatment or without physical exercise; outcome: muscle strength, muscle mass, and physical performance; Types of studies: randomized controlled clinical trials. The databases used were Pubmed, Excerpta Medica database (EMBASE), Cochrane (CENTRAL), Physiotherapy Evidence Database (PEDro), Latin American and Caribbean Health Literature in Health Sciences (LILACS), Cumulative Index to Nursing and Allied Health Literature (CINAHL), and SPORTDiscus. For gray literature, Clinical trials.gov, Proquest, and the Catalog of Theses and Dissertations of the Coordination for the Improvement of Higher Education Personnel were checked, with no language or time limit. The searches were conducted until October 10, 2024. The risk of bias of the included studies was assessed by the Cochrane Risk of Bias Tool 2 and the level of evidence by the Grading of Recommendations Assessment, Development and Evaluation. Qualitative (narrative) synthesis was performed in the review, presenting the effect measures extracted from the studies individually. Results: Eight randomized controlled clinical trials were included. Three studies demonstrated an effect on skeletal muscle mass index in favor of resistance exercise (MD = 0.32 kg/m2, 95% CI [0.04; 0.60), resistance and aerobic exercise on appendicular skeletal muscle mass index (MD = 2.4 kg/m2, 95% CI [4.1; 1.30]) and resistance exercise associated with protein supplementation (MD = 0.03 kg/m2, 95% CI [0.1 0.5]). There were no differences between the intervention and control groups for the variables muscle strength and physical performance. The included studies presented risk of bias with some concerns and high risk. Additionally, all outcomes received a low level of evidence in GRADE. Conclusion: Although exercise appears to be safe and three articles indicate a possible effect on muscle mass, the studies did not have sarcopenia as a primary outcome, with prevalence rates of <50% of sarcopenic individuals in 7 studies. Thus, there is still a lack of evidence on the real effect of physical exercise on sarcopenia in cancer patients.

This is a quantitative research, of an exploratory nature, conducted through a survey, subjects participated in the study, of both sexes and who were able to perform the 30-second sit and stand test. The objective of this study was to create an algorithm capable of automatically segmenting and identifying a sit-to-stand cycle and analyzing the similarity between the curves obtained by the smartphone and curves previously recorded by kinematography. Thus, the study was divided into two stages: stage (i) creation of the template through kinematic recordings of acceleration from the sit-to-stand test; step (ii) automated identification of the cycles recorded by the smartphone, and finally, analyze the similarity between the curves through two metrics of similarity, cross-correlation and Euclidean distance. A total of 3749 cycles were segmented, and only 3492 were considered for analysis. The preliminary result showed that there was no significant difference between the cycle counting methods (p=0.96) and that the mean similarityof the cycles studied with the template was euclidean distance (DE de 40.2 ± 8.29) e de cross-correlation (CC de 0.64 ± 0.13). The correlation between CC and DD metrics was inverse and -0.81 (p <0.0001). The cutoff points established from the cumulative distribution returned similarity indicator values related to the percentage above or below the cutoff. For example, for a cutoff of 80%, CC 0,71±0,06 (20% of curves above this value) and DE 35.3±3.99 (80% of curves below this value) were obtained. When the cutoff point was raised to 90%, CC 0,74±0,05 (10% of curves above this value) and DE 33.4±3.85 (10% of curves below this value) were obtained.

Introduction: Muscle performance patterns during gait are altered in people with Parkinson's disease. In addition, the analysis of the pendular mechanism is important because it reflects the reduction of muscular effort required to accelerate and raise the center of mass during walking. This inefficient gait pattern in people with Parkinson's disease (PwP) can result in increased energy expenditure during walking, requiring therapeutic interventions that can reduce these symptoms in order to provide greater mobility and quality of life to this population. Recent findings demonstrate that the pendular mechanism (Recovery) is greater with the use of poles, which allows to indicate the hypothesis that a neurofunctional locomotor Nordic walking (NW) rehabilitation program may induce greater adaptations in the pendular mechanism compared to free walking (FW) in individuals with PwP. Objective: To analyze the responses of a neurofunctional locomotor rehabilitation program with and without poles of NW on physiomechanical parameters of gait in PwP. Materials and Methods: This study was characterized as a longitudinal randomized controlled trial, in which we investigated volunteers who met the following eligibility criteria: clinical diagnosis of idiopathic Parkinson's disease, with staging between 1 to 4 on the Hoehn & Yahr (H&Y) scale, sedentary, over 50 years of age, of both sexes. The volunteers were randomized into two groups: NW (with poles) and FW (without poles), and performed the exercises for nine weeks. The evaluations of the physiomechanical parameters, more specifically, Recovery, Internal mechanical work (Wint), Internal mechanical work of the arm, trunk, and leg (Wint arm, Wint trunk, Wint leg, respectively), External mechanical work (Wext), vertical external work (Wext vertical) and horizontal (Wext horizontal), and Total mechanical work (Wtot) of PwP's gait were analyzed during a treadmill walk at a self-selected speed pre- and post-rehabilitation program. A three- dimensional kinematic analysis was performed, with a video capture system composed of six infrared cameras from the VICON Motion Capture System 3D kinematics (Oxford, United Kingdom), with a camera sampling rate of 100 Hz. Thirty-six reflective markers (Vicon Biomechanics Marker Accessories) in the form of a sphere, with a diameter of 14 mm, were used and located on both sides of the body and in the regions of interest. The collected data were analyzed in NEXUS software, tabulated, and organized into spreadsheets in Excel 2016 software. After these steps, mathematical routines were employed in the Matlab® software for calculating the study outcomes. Generalized Estimating Equations were used to compare between groups (NW and FW) at different time points (pre and post). We used H&Y and Froude number values of volunteers as covariates, so that the values were fixed in the statistical model at the following values: H&Y (1.5) and Froude number (0.07). For the analysis of Group, Time, and Group*Time interactions effects, Bonferroni post-hoc was used to identify differences between means in all variables. The effect size was calculated by Hedge's g, and an α=0.05 was adopted. Results: The final sample consisted of 20 volunteers (NW: n=13 and FW: n=7), with NW group (64.23 ± 10.52 years) and FW group (69.71 ± 6.82 years) mean age, NW group (80.07 ± 14.79 kg) and FW group (80.07 ± 14.79 kg) body mass, NW group (1.68 ± 0.07 m) and FW group (1.68 ± 0.06 m) height. Significant differences were found for the factor Time for the Recovery (p=0.04), Wext (p<0.001), horizontal Wext (p=0.04), and vertical Wext (p<0.001) variables. For the interaction Group*Time, significant differences were found for the Wext (p=0.03) and vertical Wext (p=0.02) variables, whereas for the other variables, the values remained similar or were not modified (p>0.05). Conclusion: We concluded that the Recovery was performed more efficiently after the locomotor rehabilitation intervention for both groups, therefore individuals with Parkinson's disease presented a more optimized pendular mechanism. The Wext of individuals with Parkinson's disease who walked with and without poles reduced after the intervention, but the FW group presented lower Wext, meaning less energy was required to move in the environment in relation to the center of mass. Both NW and FW groups reduced their vertical Wext after the rehabilitation program, but the FW group demonstrated lower post-intervention values, indicating that the volunteers did not show as much efficiency in raising their center of mass. Horizontal Wext increased for both groups after the rehabilitation program, demonstrating that both groups showed improvements in their acceleration with respect to projection forward after the intervention. Our findings indicate that the locomotor rehabilitation model with and without sticks can be used by healthcare professionals to rehabilitate locomotion, making the pendular mechanism more optimized and the gait more efficient for mild to severe PwD.

Os efeitos do treinamento pliométrico sobre o desempenho do tempo de resposta em praticantes de esportes de combate de percussão
(Universidade Federal do Pará, 2025-02-12) MACHADO, Hugo Enrico Souza; PENNA, Eduardo Macedo; http://lattes.cnpq.br/3746450308327976; https://orcid.org/0000-0003-0058-7967
Reaction time is an important variable in combat sports, as it depends on both central mechanisms (perception and information processing) and peripheral mechanisms (movement execution). Additionally, the ability to maximize force production in the shortest possible time can enhance muscle contraction speed and make strikes faster. However, little is known about the effects of power training adaptations on overall reaction time performance in combat sports practitioners. Thus, this study aimed to investigate the effects of six weeks of plyometric training on the performance of simple and choice reaction times (SRT and CRT, respectively) in striking combat sports athletes. For this purpose, 16 volunteers were divided into two groups: traditional training group (TTG = 8) and TTG + plyometric training group (TTG+PLYO = 8). Participants were assessed at two time points (pre- and post-intervention) for SRT and CRT in specific semicircular kick tasks, as well as for countermovement jump (CMJ), squat jump (SJ), horizontal jump (HJ), and reactive strength index (RSI). The TTG+PLYO group followed a six-week plyometric training (PT) program, training twice a week in addition to their regular sport-specific training. In contrast, the TTG group continued with their regular training only. For statistical analysis, a two-way ANOVA (group × time) and an independent t-test were used to evaluate the percentage of variation between groups. A significance level of p < 0.05 was adopted. Results showed no significant group × time interaction for SRT (F = 0.73; p = 0.40; η2 = 0.003) or CRT (F = 0.04; p = 0.83; η2 = 0.001). Regarding jump performance, only SJ presented a significant group × time interaction (F = 6.16, p = 0.026, η2 = 0.01), with an increase in jump height observed only in the TTG+PLYO group (pre = 30.3 ± 5.7 cm, post = 33.4 ± 5.8 cm, p = 0.01) and a significant difference in percentage variation (TTG: 0.4 ± 4.8%; TTG+PLYO: 9.1 ± 8.1%; p = 0.02). Additionally, RSI showed a significant variation only for the TTG+PLYO group (TTG = -2.3 ± 8.3%; TTG+PLYO = 24.4 ± 31.4%; p = 0.03). We conclude that six weeks of PT improved the physical performance related to power production in the TTG+PLYO group, without significant improvements in overall specific reaction time performance in combat sports practitioners.

Sitting volleyball is a paralympic sport that has shown significant growth in competitive terms in recent years, increasing the need for methods of evaluating technical-tactical aspects and physical fitness that help in monitoring the level of performance and increase in sports performance in the modality. The present systematic review was conducted in accordance with the guidelines of the Main Items for Reporting Systematic Reviews and Meta-Analyses (PRISMA) and aimed to identify and analyze indicators of performance and physical fitness in sitting volleyball players. The searche was carried out in four databases (Scopus, Pubmed, Web of Science and Scielo) and studies that quantitatively evaluated performance indicators or physical fitness components in sitting volleyball athletes of any gender, age or competitive level were included. The methodological quality of the articles included was evaluated by the Critical Review Form for Quantitative Studies (LAW et al., 1998) and the results presented through narrative synthesis. In total, 37 studies were included, with an average quality score of 72.25%. The findings showed that attacking and blocking were the main terminal actions in sitting volleyball. Significant correlations between physical fitness measures (power, speed, agility, endurance, flexibility, reaction speed and body composition) with specific technical skills were identified. While limited evidence indicates that: male athletes perform better than female athletes; that elite athletes are physically and technically superior to sub-elite ones. In addition, the studies did not point out significant differences in the effectiveness in game actions between athletes of different functional classes.

Introduction: Chronic kidney disease (CKD) often evolves silently at different stages, and stage 5 is the most advanced and severe, usually requiring renal replacement therapy. As the disease progresses, the metabolic alterations resulting from reduced renal function can lead to neuromuscular disorders and reduced functional performance in this population. Objectives: To assess neuromuscular function and oxidative stress in people undergoing an unplanned transition to stage 5 CKD at the start of hemodialysis. Methods: Cross-sectional study evaluating neuromuscular function (functional capacity [1-minute sit-to-stand test], peripheral muscle strength [isometric dynamometry of lower limbs], respiratory muscle strength [manovacuometry] and neuromuscular excitability [stimulus electrodiagnostic test]) and oxidative stress [malondialdehyde] in people in unplanned transition to stage 5 CKD who started hemodialysis on an emergency basis (CKD group) compared to people without CKD (control group) and them association. Results: Twenty-four participants, 14 in the control group without CKD (42 ± 12 years) and 14 in the CKD group (53 ± 18 years), were evaluated. The CKD group compared to controls without CKD present impaired functional capacity (13.8 ± 4.9 vs 36.7 ± 9.1 repetitions, p < 0.001), on peripheral muscle strength of lower limbs (knee extenders [12.3 ± 4.6 vs 23.5 ± 9 kgf], knee flexors [11.3 ± 3.2 vs 17.8 ± 4.3 kgf], dorsiflexors [8.7 ± 2.8 vs 16.7 ± 4.3 kgf] and plantar flexors [11.2 ± 2.5 vs 16.6 ± 4.4 kgf], all p < 0.001), expiratory muscle strength (60 ± 23 vs 83 ± 27 cmH2O, p = 0.02) and neuromuscular excitability (chronaxy of the vastus lateralis, 654 ± 230 vs 415 ± 190 μs, p = 0.008; chronaxy of the tibialis anterior, 600 [500 – 1000] vs 400 [300 – 400] μs, p = 0.001),. Inspiratory muscle strength (-70 ± 33 vs -87 ± 29 cmH2O, p = 0.7) and oxidative stress (3.51 ± 1.13 vs 3.53 ± 0.92 nmol/ml, p = 0.95) showed no significant differences. In the CKD group, functional capacity was influenced only by peripheral muscle strength, while expiratory muscle strength and functional capacity demonstrated influence on peripheral muscle strength. Conclusion: People in unplanned transition to stage 5 CKD who start hemodialysis on an emergency basis have altered in neuromuscular function. The findings of this study can guide screening and monitoring strategies for neuromuscular deficiencies and rehabilitation planning.
