RESUMO
OBJECTIVE: The aim of our study was to assess postoperative lower limbs muscle strength (MS) as a predictor of late surgical success (36 months). METHODS: Body composition analyses and isokinetic dynamometry evaluation were performed before (T0: n=123), six months (T1: n=123) and 36 months (T2: n=79) after Roux-en-y gastric bypass (RYGB). Surgical success (SS) was defined as ≥ 50% excess weight loss (EWL) 36 months after surgery or ≤ 50% surgical failure (SF). RESULTS: There was no difference between relative MS extension (Ext) and flexion (Flex) in T1 and T2. There was also, no difference between relative MS Ext and Flex in T1 and T2 between patients with SS and SF. There was a difference in relative MS Ext (144.9 ± 39.8 Nm/kg x 125.5 ± 29.2 Nm/kg; p=0.04) and Flex (73.6 ± 21.8 Nm/kg x 60.4 ± 15.8 Nm/kg; p=0.02) between SS and SF patients only in T2. Patients with an increment in Ext and Flex MS ≥4 Nm/kg at T1 had approximately 76% of SS at 36 months. CONCLUSION: An increase of lower limbs MS ≥4 Nm/kg 6 months after RYGB predicts SS at 36 months. CLINICALTRIALS: gov ID: NCT04129801.

RESUMO
INTRODUCTION: Advanced Glycation End-Products (AGEs) are a diverse group of highly reactive molecules that play a vital role in the development of neurodegenerative disorders, such as Parkinson's Disease (PD), leading to a decline in functional and cognitive capacity. The objective of this study was to assess the intake and quantification of AGEs in individuals with PD and to correlate them with their functional and cognitive abilities. METHODS: This was a cross-sectional study involving 20 PD patients and 20 non-PD individuals as the Control group (C). The autofluorescence reader was used to evaluate skin AGEs, while food recall was used to quantify AGEs consumed for three different days. The Montreal Cognitive Assessment, Short Physical Performance Battery, and handgrip tests were used. PD patients demonstrated greater impairment in functional capacity compared to the control group. RESULTS: Dominant Handgrip (p = 0.02) and motor performance, in the sit and stand test (p = 0.01) and Short Physical Performance Battery (SPPB) (p = 0.01) were inferior in PD patients than the control group. Although PD patients tended to consume less AGEs than the control group, AGE intake was negatively correlated with handgrip strength in individuals with PD (r = -0.59; p < 0.05). CONCLUSION: PD patients had lower strength and functional capacity, suggesting that the effects of AGEs might be exacerbated during chronic diseases like Parkinson's.

Objective: Evaluate and correlate the sagittal balance parameters with the postural of the pelvis and lumbar spine. Methods: 80 individuals of both sexes, aged between 20 and 35 years, were evaluated. Biophotogrammetry was done with the SAPO software program. Measurements of the sagittal balance parameters were obtained by analyzing a lateral view panoramic radiography of the vertebral column, in which the anatomical points of reference were digitally marked. The calculation of the angles was done automatically by the Keops program. Results: In Keops assessment, 17.5% of the sample had high pelvic incidence angles (> 60°), 31.5% had low pelvic incidence angles (< 45°), and 51.2% had medium pelvic incidence angles (between 46° and 59°). SAPO showed 12,5% lordosis, 40% retroversion, and 47,5% normal curvature. In the right lateral view, pelvic incidence angle had a moderate and positive correlation with vertical alignment of the trunk and with vertical alignment of the body, and a negative and moderate correlation with horizontal alignment of the pelvis. Conclusion: Differences were found between vertical alignment measurements from the postural evaluation system (SAPO). A positive correlation was found between PI from Keops and pelvic anteversion from SAPO. Level of Evidence II; Prospective Study.

RESUMO
Objective: After deep brain stimulation (DBS), patients with Parkinson's disease (PD) typically still present significant gait and postural stability problems, and thus additional interventions are needed. In this way, our purpose was evaluate the comparative effectiveness of treadmill training, with and without body weight support, on balance outcomes among patients with PD after DBS. Methods: Eleven patients with PD that were using bilateral subthalamic nucleus DBS were evaluated using Time Up and Go test (TUG); Berg Balance Scale (BBS) and Static Posturography. In phase 1, all subjects participated in 8-weeks of treadmill training in conjunction with conventional physiotherapy. After six weeks (wash-out), each patient then participated in a subsequent 8-weeks of treadmill training with partial body weight support. Results: After the phase 1, there were improvements on the cognitive TUG performance (Before: 15.7 ± 1,8 sec; After: 13.7 ± 3.1 sec; p < 0.01) and an increase of anteroposterior and medio-lateral body oscillation with eyes closed. After the phase 2, there were improvements in conventional (Before: 12.3 ± 2.0 sec; After: 10.7 ± 1.7 sec; p < 0.01) and cognitive (Before: 14.6 ± 3.5 sec; After: 12.5 ± 1.6 sec; p < 0.05) TUG performances. There were no significant changes in the Berg Balance Scale following either training protocol. Conclusion: Both trainings improved static and dynamic balance and had similar results; however, supported treadmill training seemed to be a potentially superior option, as patients tended to feel safer. Level of Evidence II, therapeutic studies - investigation of treatment outcomes.
Objetivo: Mesmo após a estimulação cerebral profunda (ECP), os pacientes com doença de Parkinson (DP) muitas vezes ainda apresentam problemas significativos de marcha e estabilidade postural, e, portanto, intervenções adicionais são necessárias. Avaliar a eficácia comparativa do treinamento em esteira, com e sem suporte de peso corporal, nos resultados de equilíbrio de pacientes com DP após ECP. Métodos: Onze pacientes com DP em uso de ECP bilateral do núcleo subtalâmico foram avaliados pelos testes Time Up and Go (TUG), escala de equilíbrio de Berg (EEB) e posturografia estática. Na fase 1, todos participaram de oito semanas de treinamento em esteira em conjunto com fisioterapia convencional. Após seis semanas (wash-out), cada paciente participou de oito semanas subsequentes de treinamento em esteira com suporte parcial de peso corporal. Resultados: Depois da fase 1, houve melhora no desempenho cognitivo do TUG (antes: 15,7 ± 1,8 s; depois: 13,7 ± 3,1 s; p < 0,01) e aumento da oscilação anteroposterior e médio-lateral do corpo com os olhos fechados. Após a fase 2, os resultados do TUG convencional (antes: 12,3 ± 2,0 seg; depois: 10,7 ± 1,7 seg; p < 0,01) e cognitivo (antes: 14,6 ± 3,5 s; depois: 12,5 ± 1,6 s; p < 0,05) demonstraram melhora. Os protocolos de treinamento não causaram mudanças significativas na EEB.. Conclusão: Ambos os treinos melhoraram o equilíbrio estático e dinâmico e tiveram resultados semelhantes; no entanto, o treinamento em esteira com suporte é uma opção potencialmente superior, uma vez que os pacientes tendiam a se sentir mais seguros. Nível de Evidência II, estudos terapêuticos - investigação de resultados de tratamento.
RESUMO
CONTEXT: Vehicle driving depends on the integration of motor, visual, and cognitive skills to respond appropriately to different situations that occur in traffic. OBJECTIVES: To analyze a model of performance predictor for braking time in the driving simulator, using a battery of tests divided by gender. METHODS: Selected were 100 male drivers with a mean age of 72.6 ± 5.7 years. Sociodemographic variables, braking time in the driving simulator, and motor, visual, and cognitive skills were evaluated. RESULTS: Comparing genders, men were older than women (p = 0.002) and had longer driving times (p = 0.001). Men had more strength in hand grip (p ≤ 0.001). In the linear regression analysis, the model explained 68 % of the braking time in men and 50.8 % in women. In the stepwise multiple linear regression analysis, the variable that remained in the model was the strength of the right plantar flexors, which explained 13 % of the braking time in women and men, and the cognitive variables explained 38.9 %. CONCLUSION: Sociodemographic, motor, visual, and cognitive variables, explained a substantial portion of the variability in braking time for both older women and men, the specific variables driving this performance differed between the sexes. For older women, factors such as muscle strength emerged as critical determinants of braking ability, highlighting the importance of physical health in maintaining driving skills. On the other hand, cognitive conditions emerged as the primary predictor of braking performance in older men, underscoring the role of mental acuity and decision-making processes in safe driving.

Objectives: To assess the effectiveness of transcranial direct current stimulation (tDCS) for pain, fatigue, physical function, and health-related quality of life in patients with idiopathic inflammatory myopathy (IIM). Methods: This randomized, double-blind, sham-controlled, crossover clinical trial enrolled IIM patients with fatigue and pain who received tDCS (20 min, 2 mA) or sham stimulation for 10 daily sessions. Electrodes were placed according to the 10/20 EEG system. Both the groups underwent aerobic exercise training during the intervention period. The patients were evaluated for disease perception, pain, and fatigue using uni-multidimensional questionnaires and physical tests in the periods before and after the first and second interventions and after 12 weeks of follow-up. Results: After the tDCS intervention, a reduction in the general score of multidimensional pain of 32.0 (1.5-38.0) vs. 0.0 (0.0-13.4) with effect size (ES) of -0.78 was noted, and after sham intervention, a reduction of 26.0 (0.0-37.0) vs. 5.0 (0.0-19.2) with ES of -0.54 (P = 0.047) was also noted. Similar results were evidenced with fatigue (22.5 (15.4-33.2) vs. 5.5 (0.0-14.6) with ES of -0.82) and sham intervention (21.0 (15.8-29.5) vs. 4.0 (4.0-17.5) with ES of -0.80 (P = 0.012)). There were no differences in the domains of the fatigue and pain questionnaires. Adherence was observed in 88.8% of the patients without adverse events. Conclusion: The association of tDCS with aerobic training promoted additional effects in relation to the group subjected to placebo stimulation on general pain and fatigue scores, as well as on pain intensity, without changes in the subdomains of the pain and fatigue questionnaire. This trial is registered with NCT04678635.
RESUMO
INTRODUCTION: An accurate assessment of balance problems is critical for decreasing the risk of falling in patients with Parkinson's Disease (PD). Reliable diagnostic tools such as Computerized Dynamic Posturography (CDP) are not feasible for the clinical setting. Therefore, the present study's aim was to assess the correlation between the clinical Balance Evaluation Systems Test (BESTest) and CDP. METHODS: 20 male older adults with Parkinson's Disease (PD) were included in this study. Participants first executed the Sit-To-Stand (STS), Step/Quick turn (SQT), and Step Up and Over (SUO) tests on a Balance Master® force platform, followed by a clinical balance evaluation using the BESTest. RESULTS: Four outcomes of the CDP were negatively correlated with one or more BESTest domains or total BESTest score: STS sway velocity was negatively correlated with the anticipatory postural adjustment (p = 0.02) and sensory orientation (p = 0.01) domains. SQT turn time was negatively correlated with biomechanical restriction (for turns to the left, p = 0.01, and right, p = 0.03, respectively), postural response (p = 0.01, p = 0.01), dynamic balance during gait (p = 0.007, p = 0.001), and total score (p = 0.02, p = 0.01). Step over time to the right in SUP was negatively correlated with the limits of the stability domain (p = 0.002) and total BESTest score (p = 0.020). SUO impact index was negatively correlated with the anticipatory postural adjustment domain (p = 0.01). CONCLUSION: This study shows that several BESTest domains are significantly correlated with CDP outcomes, demonstrating that the BESTest can be used as a more clinically feasible alternative for computerized posturography, without loss of information.

OBJECTIVE: To investigate the effect of 12 weeks of rehearsals on cardiorespiratory parameters and body composition in Brazilian samba dancers belonging to a first-league samba school. METHODS: Twenty-six women were divided into a Samba Group (n=13) and a Control Group (n=13). Cardiorespiratory parameters (cardiopulmonary exercise test) and body composition (skinfold assessment) were assessed before and after the 12 weeks of rehearsals. The Samba Group rehearsed three times per week for 30-60 minutes, and the Control Group participated in no physical activity. A comparison test was performed within and between groups, with p<0.05 indicating statistical significance. RESULTS: Compared with the Control Group, the Samba Group showed a significant increase in maximal oxygen uptake (19%), oxygen pulse (13%), and lean body mass (3%) and a decrease in body fat percentage (11%) and fat mass (12%). CONCLUSION: Twelve weeks of samba dance rehearsals improved the cardiorespiratory and body composition parameters in women dancers compared with the Control Group. These findings suggest that dancing samba regularly can increase physical activity levels and positively affect the health parameters of samba dancers.

ABSTRACT Objective As the soccer culture in Brazil is more popular than schooling, this study reflected on the formal education levels of soccer (football) players through descriptive and quantitative analyses. Methods We evaluated 179 national soccer players playing various positions on different teams across six seasons (2012, 2013, 2014, 2015, 2016, and 2022). Data were collected using a questionnaire comprising the following variables: age, position in the pitch, age of professionalization, and education (years of study). The data were distributed according to the pitch position. Results The mean age, length of professional career, and professionalization age were 23±6 years, 7±5 years, and 17±2 years, respectively. In terms of education, 121 athletes (67%) completed high school, equivalent to 11 years of study. Only 5.5% completed higher education, with defensive players (goalkeepers and defenders) being the most educated at 37% (66/179). According to 2017 figures from the Pesquisa Nacional por Amostra de Domicílios Contínua of the Federal Government of Brazil, the schooling rate is 31.7%, wherein 46.1% of Brazilians aged 25 years or over have completed education. In this study of 179 athletes, 67% had completed high school. Thus, players outrank the Brazilian population in terms of achieving a high school education. There were marked disparities in the relative proportions of goalkeepers (85%), defensive players (68%), midfielders (63%), and forward players (64%) in terms of their education. Conclusion Our survey revealed that attending higher education remains a distant reality in Brazil.

RESUMO
OBJECTIVE: This study aimed to evaluate if posturography can be considered a recurrent fall predictor in elderly individuals. METHODS: This was a cross-sectional study. A total of 124 subjects aged 60 to 88 years were evaluated and divided into two groups—the recurrent fallers (89) and single fallers (35) groups. Patients' sociodemographic characteristics were assessed, and clinical testing was performed. The functional test assessment instruments used were timed up and go test (TUGT), Berg Balance Scale (BBS), five times sit-to-stand test, and Falls Efficacy Scale (to measure fear of falling). Static posturography was performed in a force platform in the following three different situations—eyes open (EO), eyes closed (EC), and EO dual task. RESULTS: There were significant differences between the single and recurrent fallers groups regarding the fear of falling, the Geriatric Depression Scale score, the mean speed calculated from the total displacement of the center point of pressure (COP) in all directions with EO, and the root mean square of the displacement from the COP in the mediolateral axis with EC. Based on the hierarchical logistic regression model, none of the studied posturographic variables was capable of significantly increasing the power of differentiation between the recurrent and single fallers groups. Only TUGT with a cognitive distractor (p<0.05) and the BBS (p<0.01) presented with significant independent predictive power. CONCLUSION: TUGT with a cognitive distractor and the BBS were considered recurrent fall predictors in elderly fallers.

ABSTRACT Introduction: The limit of stability is characterized by the maximum angle of inclination that an individual can reach and greater variability in extreme conditions; it is a bold and/or dangerous motor control strategy. Objective: Assess whether anthropometric measurements and body composition interfere with limits of stability and weight-bearing at different speeds in adults. Methods: Eighty-seven subjects of both sexes aged between 20 and 40 years were analyzed using anthropometric assessment and body composition. A force platform, limits of stability (LoS) and rhythmic weight shift (RWS) tests were used for the balance assessments. Results: In the LoS test, being female was negatively correlated with foot size and reaction time, and positively correlated with maximum excursion. In the RWS test, the female group had a negative correlation with height and upper limb length (ULL), with mediolateral directional control. The male group had a negative correlation with ULL and laterolateral directional control. Conclusion: Body composition variables do not interfere in the LoS and RWS tests in subjects with normal body mass index (BMI) values, except for bone densitometry (BMD) in women. As regards anthropometric parameters, height, ULL and foot size in the female and male groups were as follows: ULL and foot size exert little influence on postural balance control.

RESUMO Introdução: O limite de estabilidade caracteriza-se pelo ângulo máximo de inclinação que um indivíduo pode alcançar e pela maior variabilidade em condições extremas; trata-se de uma estratégia arrojada e/ou perigosa do controle motor. Objetivos: Avaliar se as medidas antropométricas e a composição corporal interferem nos limites de estabilidade e nas descargas de peso em diferentes velocidades em adultos. Métodos: Foram analisados 87 indivíduos de ambos os sexos, entre 20 a 40 anos de idade, por meio de avaliação antropométrica e composição corporal. Para as avaliações de equilíbrio foram usados uma plataforma de força, testes de limite de estabilidade (LE) e troca rítmica de peso (TRP). Resultados: No teste de LE, o sexo feminino correlacionou-se negativamente com o tamanho do pé e o tempo de reação e positivamente com a excursão máxima. Na TRP, o grupo feminino apresentou correlação negativa com estatura e comprimento do membro superior (CMS) com controle de direção médio-lateral. O grupo masculino apresentou correlação negativa com CMS e controle de direção látero-lateral. Conclusões: As variáveis de composição corporal não interferem nos testes de LE e TRP em indivíduos que apresentam valores de índice de massa corporal (IMC) dentro da normalidade, exceto a densitometria óssea (DMO) em mulheres. Quanto aos parâmetros antropométricos, estatura, CMS e tamanho dos pés no grupo feminino e no masculino foram os seguintes: CMS e tamanho dos pés têm pouca influência no controle do equilíbrio postural.

RESUMO
ABSTRACT Objective: To evaluate bone mineral density (BMD) and body composition over a six-year period in elderly long-distance runners. Methods: We analyzed the medical records of elderly athletes who were long-distance runners, were participants of the IOT-HCFMUSP Orthogeriatric Group, and had their BMD evaluated between 2001 and 2007; of these athletes, 11 were included in the study. Inclusion criteria: athletes should be long-distance runners, should not stop long-distance running during the six-year period, and should have undergone BMD and body composition evaluations. Body composition was evaluated using bone densitometry with dual-energy X-ray absorptiometry with a Lunar-DPX device. Results: Over the six-year period, body composition remained stable, but there was a significant increase only in the fat percentage (p = 0.003). Conclusion: Long-distance running may maintain BMD but may lead to an increase in the fat percentage in elderly runners.

OBJECTIVE: To evaluate the factors associated with traffic motorcycles accidents. METHODS: The sample consisted of 285 motorcycle accident victims in São Paulo. Data were collected from 24-hour emergency service shifts regarding: conditions of the victims, security equipment, road and vehicle conditions. RESULTS: Victims were mostly young men (92%); 23% used the motorcycle for work (average: 8 hours per day); 45% had owned a motorcycle for less than two years; 77% were licensed motorcycle drivers; 33% had less than four years of qualification; 31% had attended a course of defensive driving. Severe lesions were identified in 67% of the unlicensed drivers. Polytrauma occurred in 9% head trauma in 5% of the entire population. Lower limb fractures occurred more frequently than upper limb (17% vs. 12%). Most wore helmets (90%) but only 18% wore helmet, boots and jacket. Positive readings for alcohol (7%) and drugs (14%) occurred in 21% of victims. Most accidents occurred as a consequence of imprudence (88%), during the day (67%), in dry weather conditions (94%). A side impact was registered in 48% of cases; 80% of motorcycles had an engine capacity up to 250 cc. In 51% of the accidents the person responsible for the accident was the driver of the other vehicle in the accident. CONCLUSION: Most accidents involve motorcyclists who are young male adults, use the motorcycle as a means of transport and do not consider safety, defensive driving and the use of alcohol and drugs as important factors.
OBJETIVOS: Avaliar fatores associados com acidentes de trânsito com motocicletas. MÉTODOS: Foram avaliadas 285 vítimas de acidente de motocicleta em São Paulo. Os dados foram coletados em plantões nas unidades de emergência. Foram coletadas informações sobre: condições das vítimas, uso de equipamentos de segurança, condições de estrada e veículo. RESULTADOS: As vítimas eram principalmente homens jovens (92%); 23% usavam a motocicleta para o trabalho (média: 8 horas por dia); 45% possuíam a motocicleta por menos de dois anos; 77% tinham habilitação para dirigir; 33% tinham menos de quatro anos de habilitação; 31% tinham feito curso de direção defensiva. Lesões graves foram identificadas em 67% dos motoristas não habilitados. Houve politraumatismo em 9% das vítimas e traumatismo craniano em 5% da população avaliada. Fraturas de membros inferiores ocorreram mais frequentemente do em membros superiores (17% contra 12%). A maioria usava capacetes (90%), mas apenas 18% usava capacete, botas e jaqueta. Dosagens positivas de álcool (7%) e drogas (14%) foram vistas e totalizaram 21% de todas as vítimas. A maioria dos acidentes ocorreu como consequência de imprudência (88%), durante o dia (67%) e sem chuva (94%). CONCLUSÃO: A maioria dos acidentes envolve vítimas do sexo masculino, adultos, que usam a motocicleta como meio de transporte e não consideram equipamentos de segurança, condução defensiva e o consumo de álcool e drogas fatores importantes para prevenção dos acidentes.

Desta forma, são necessários estudos que mostram a confiabilidade desta ferramenta para auxiliarem na prevenção de lesões do tornozelo. Objetivo: Elaborar uma revisão de literatura sobre estudos que abordaram a confiabilidade de testes isocinéticos da articulação do tornozelo. Métodos: A busca na literatura foi realizada nas bases de dados Pubmed, Lilacs, Pedro, Scielo, Scopus e Cochrane com os descritores científicos ankle e isokinetic e reliability. Foram identificados 34 artigos, 4 foram excluídos por não estudarem humanos e 27 foram incluídos (10 referentes à confiabilidade de testes isocinéticos para inversores e eversores do tornozelo e 17 referentes à confiabilidade de testes para flexores-plantares e dorsiflexores). Resultados: A confiabilidade da avaliação isocinética dos flexores-plantares e dorsiflexores tem sido descrita para diferentes dinamômetros, posições, modos e populações. Os valores de coeficientes de correlação intraclasse variam de 0,55-0,98; e a de eversores e inversores, variam de 0,54-0,99, classificados na faixa de satisfatório a excelente. Conclusão: Os protocolos isocinéticos da articulação do tornozelo devem ser elaborados de acordo com a musculatura recrutada e com a população (com presença ou não de patologia).

Thus, studies that show the reliability of this tool are needed to help the ankle injury prevention. Objective: To develop a literature review about studies that show the reliability of ankle isokinetic test. Methods: The literature search was conducted in Pubmed, Lilacs, Peter, Scielo, Scopus and Cochrane with key words: isokinetic and ankle and reliability. 34 articles were identified, 4 were excluded because they did not study humans and 27 were included (10 about the reliability of ankle inverters and everter isokinetic tests and 17 about the reliability of tests for ankle flexor-plantar and dorsiflexors). Results: The reliability of isokinetic test has been described for different dynamometers, positions, modes and populations. The values of intraclass correlation coefficients ranged from 0.54 to 0.99, which were considered satisfactory to excellent. Conclusion: Ankle isokinetic protocols must be prepared in accordance with the recruited muscles and the population (with or without pathology).

ABSTRACT Objective: To evaluate the association between bone mineral density (BMD) and body composition in healthy older adults at different skeletal sites. Methods: We analyzed 87 medical records and BMD along with the body composition of men ranging from 60 to 87 years of age (mean: 68.5, standard deviation: 6.5). Inclusion criteria were normal BMD values (T-score greater than or equal to -1.0) and body mass index within normal or overweight range (18.5 to 29.5 kg/m2). Body composition was evaluated using bone densitometry with dual-energy X-ray absorptiometry (DEXA) in a LUNAR-DPX apparatus. Results: Greater lean mass, fat mass, and soft tissue was associated with better BMD values in older adults, and higher age was associated with poorer BMD. Conclusion: Body composition (lean and fat masses and soft tissue) in older men is positively associated with BMD at all body sites (arms, legs, and trunk). Level of Evidence II; Prognostic studies - Investigating the effect of a patient characteristic on the outcome of disease.
RESUMO Objetivo: Avaliar a associação entre a DMO e a composição corporal em idosos hígidos em diferentes sítios esqueléticos. Métodos: Foram analisados 87 prontuários e exames de DMO com composição corporal de idosos do sexo masculino com média de idade de 68,5 (6,5) variando de 60 a 87 anos. Os critérios de inclusão foram valores de DMO dentro do normal (T-score maior ou igual a -1,0); IMC dentro dos valores normais ou sobrepeso (18,5 a 29,5 kg/m2). A composição corporal foi avaliada por meio de densitometria óssea por dupla emissão de raios-X (DEXA) em aparelho LUNAR-DPX. Resultados: Quanto maior as massas magra e gorda e os tecidos moles, melhor os valores da DMO dos idosos e quanto maior a idade, pior a qualidade da DMO. Conclusão: A composição corporal (massas magra e gorda e tecidos moles) de homens idosos associa-se positivamente na DMO em todos os locais do corpo (membros superiores, inferiores e tronco). Nível do Evidênci II; Estudos prognósticos - Investigação do efeito de caractetísticas de um paciente sobre o desfecho da doença.
RESUMO
The aim of this study was to verify body composition, cardiorespiratory fitness, and biochemical markers of prepubertal overweight and obese boys to a 16-week futsal training program. Methods: Sixteen boys (age: 7-10 y, body mass index>thanat 95th percentileaccording to Center for Disease Control and Prevention; 35.5±7.4 percent fat) participated to futsal training program. The assessment of body composition was estimated using skinfold thickness, and the following variables were evaluated: total body mass, body mass index, body fat percentage, and lean body mass. Aerobic fitness measurementwas performed by gas exchange analysis in treadmill. In addition, an evaluation of the biochemical profile was conducted: triglycerides, total cholesterol, low density lipoprotein cholesterol, high-density lipoprotein cholesterol, plasma concentrations of glucose, and insulin. The futsal intervention included 60-min sessions performed two times/week. The mean intensity during training was between 57 to 88% of maximal heart rate of the age-predicted. Individual portable heart rate monitor controlled training intensity. Results: Significant increases in total body mass (4%), height (3%), lean body mass (8%), and significant 6%-decrease in body fat percentage was observed. Body mass index remained unchanged. Maximal oxygen uptake was elevated (p<0.018) by 11%. Biochemical markers were not modified after intervention. No association was found between body composition and metabolic variables. The effect size of futsal training on most variables was small (<0.5). Conclusion: Controlled intensity and adherence to this 16-week futsal training program were determinant to enhance body composition, and cardiorespiratory fitness in this group of prepubertal boys.(AU)

OBJECTIVES: This study sought to analyze the extent of motor adaptation in ankle plantar flexors and dorsiflexors among older drivers during clinical isokinetic testing. METHODS: One hundred older adults (70.4±5.7 years) participated in two bilateral ankle plantar flexor and dorsiflexor isokinetic assessments at 30°/sec. Peak torque (PTQ), PTQ adjusted for body weight (PTQ/BW), and total work (TW) were analyzed. RESULTS: On the dominant side, PTQ/BW and TW were significantly greater for the second plantar flexion test than were those for the first such test (p<0.001), whereas PTQ, PTQ/BW, and TW (p<0.001) were significantly greater for the second dorsiflexion test than were those for the first such test. On the non-dominant side, plantar flexion PTQ and TW were significantly lower for the second test than were those for the first test (p<0.001). CONCLUSION: Older drivers demonstrated better performance with the dominant limb on the second test. The low variability in test execution showed the existence of a motor adaptation effect for the tested movements, despite the short recovery period between the assessments.
