Exergames have already been used as therapeutic tools to enhance both physical and cognitive functions in older adults. Aim To evaluate the effects of a Kinect‐based physical activity program on the quality of life, depression, functional fitness and body composition in institutionalized older adults. Methods A total of 50 older adults aged >60 years were selected and randomized to a control and video game group. Body composition was determined by means of anthropometric measurements. Quality of life was assessed using the WHOQOL‐BREF questionnaire, and depression was classified using the Beck Depression inventory. Functional fitness was assessed using the Arm Curl, Chair Stand, 8‐foot up‐and‐go, sit and reach, and the aerobic endurance test. Results After 12 weeks of protocol, we observed a significant improvement in all functional fitness parameters. Conclusions Our findings suggest that a Kinect‐based physical activity program seems to positively impact the three domains related to quality of life and directly associated with age (physical, social and psychological domains), and to promote a more active lifestyle in institutions housing older individuals.

Although no significant differences were observed between the two interventions in relation to the hormonal and metabolic parameters analyzed, both training methods promoted a favorable response, with a slight superiority noted for the CI method relative to the hormonal profile.

Introdução: a avaliação da percepção de esforço (PSE) e estados de humor (EH) em diferentes intensidades de esforço, pode auxiliar o planejamento do programa de treinamento minimizando o risco de overtraining e lesões osteomioarticulares.Objetivo: comparar as respostas de PSE e estados de humor em individuos submetidos a duas intensidades distintas de corrida de 5km.Métodos: corredores de rua recreacionais (n: 14) do Clube de Corrida da Universidade Federal de Sergipe (UFS) foram submetidos a um teste de 5Km. Posteriormente a realização do teste todos os individuos foram submetidos a dois testes de 5km randomizados  com diferentes intensidades  sendo a 95% e 85% da velocidade do teste de 5km.  Foram avaliados o tempo total, a veocidade media, a percepçaõ de esforço, a carga interna e os parámetros vigor e fadiga.Resultados: O protocolo de corrida C5K85 apresentou redução significativa (p 0,001) das variáveis velocidade média de corrida, PSE e CIT quando comparado ao protocolo C5K95. A variável fadiga apresentou aumento significativo (p 0,001) pós-esforço no protocolo C5K95, sem mudanças significativas no protocolo C5K85 (p0,05). Conclusão: a percepção subjetiva de esforço, a carga interna de treino e a subescala fadiga do questionário BRUMS podem ser utilizados como ferramentas para controle e monitoramento da intensidade de treinamento em corredores de 5km.

Cardiovascular disease, cancer, respiratory and metabolic disease represent 63% of all deaths worldwide and are considered the major causes of morbidity and mortality. Physical inactivity is considered a case of public health, and other behavioral and metabolic risk factors, according to WHO (2011), such as smoking, increased blood pressure, increased blood glucose, hypercholesterolemia, overweight and obesity. The Nonalcoholic Fatty Liver Disease (NAFLD) is the most prevalent liver disease in adults, and can progress and be characterized as hepatic steatosis (HS) which is derived from the accumulation of lipids in hepatocytes, and histopathologic condition is more than 5% of the weight of liver. So, the purpose of this study is to identify the relationship between the physical activity level and the hepatic steatosis presence, metabolic syndrome and the risk of developing type 2 diabetes mellitus in men. We evaluated retrospectively medical records of 1399 men (40.7 ± 8.18 years old) who participated in the protocol of Preventive Health Check-up at Hospital Israelita Albert Einstein from January to October 2011. According to the results, it is concluded that there is a positive association between low physical activity level and the presence of Hepatic steatosis. The results further demonstrate that, despite the high BMI, blood levels of the subjects remained unchanged. Even without a positive association between these variables, the results showed a high risk behavior for the development of diabetes mellitus type 2.

Background: muscle activation measured by electromyography (EMG) provides additional insight into functional differences between movements and muscle involvement. Objective: to evaluate the EMG of triceps surae during heel-raise exercise in healthy subjects performed at leg press machine with different feet positions. Methods: ten trained healthy male adults aged between 20 and 30 years voluntarily took part in the study. After biometric analyses the EMG signals were obtained using a 8-channel telemeterized surface EMG system (EMG System do Brazil, Brazil Ltda) (amplifier gain: 1000x, common rejection mode ratio >100 dB, band pass filter: 20 to 500 Hz). All data was acquired and processed using a 16-bit analog to digital converter, with a sampling frequency of 2kHz on the soleus (Sol), medial (GM) and lateral (GL) gastrocnemius muscles in both legs, in accordance with the recommendations of SENIAN. The root mean square (RMS) of the EMG amplitude was calculated to evaluate muscle activity of the three muscles. After being properly prepared for eletromyography procedures, all subjects were instructed to perform 3 sets of 5 repetitions during heel-raise exercise using the maximal load that enabled 10 repetitions on leg press 45° machine, each set being performed with one of the following feet positions: neutral (0º), internal and external rotation (both with 45° from neutral position). The tests were sequential and applied a 5-minute rest interval between sets. The order of the tests was randomized. Results: thought had been found interaction (F=0.27, P= 0.75) on RMS parameters and feet position, the values of Sol muscle were significantly (F=17.86, P= 0.003) lower compared with GL and GM muscles independently of feet position. Conclusion: The change in the feet position during the heel-rise exercise performed in the leg press does not influence the activation of the triceps surae, and the soleus is less activated than the gastrocnemius in that exercise.

Introduction Erectile dysfunction, defined as the inability to achieve and/or maintain a penile erection sufficient for satisfactory sexual intercourse is associated with impaired quality of life and cardiovascular diseases in men older than 40 years. Objective To evaluate the association between erectile dysfunction and physical activity levels in a large cohort of men. Methods Data from 20,789 males aged 40 years and over who participated in the check-up screening between January of 2008 and December of 2018 were included in this study. In this sample, data about erectile dysfunction, physical activity levels, clinical profile and laboratory exams were obtained. Logistic regression models were performed. Results Individuals with erectile dysfunction were older (49.1 ±6.9 vs. 54.8±8.8 years old, p<0.001), had a higher body mass index (27.6 ±3.9 vs. 28.5 ± 4.3 kg/m2, p<0,001), and presented with a higher prevalence of physical inactivity (25 vs. 19%, p<0.001) than individuals without erectile dysfunction. The multivariate model revealed that age (p<0.001), hypertension (p = 0.001), diabetes mellitus (p<0.001), high body mass index (p<0.001), lower urinary tract symptoms and depressive symptoms (p<0.001) were independent risk factors for erectile dysfunction. Low or high physical activity levels (OR = 0.77; CI95%: 0.68–0.87, p<0.001 and OR = 0.85; CI95%: 0.72–0.99, p = 0.04 respectively) were protective factors against erectile dysfunction. Conclusion Low and high physical activity levels were associated with more than 20% reduction in the risk of erectile dysfunction in men aged 40 years or older.
