FUNDAMENTOS E OBJETIVOS: A prática de exercício físico, além de combater o sedentarismo, contribui de maneira significativa para a manutenção da aptidão física do idoso. O objetivo do estudo foi verificar o efeito da prática de hidroginástica sobre a aptidão física do idoso associada à saúde. METODOLOGIA: Foi realizado um ensaio controlado em 74 mulheres idosas, sem atividade física regular. Um grupo de 37 mulheres recebeu duas aulas semanais de hidroginástica durante três meses e outras 37 mulheres serviram como controle. A aptidão física foi avaliada através da bateria de testes de Rikli e Jones (1999), com avaliações de força e resistência de membros inferiores (levantar e sentar na cadeira), força e resistência de membros superiores (flexão do antebraço), flexão de membros inferiores (sentado, alcançar os membros inferiores com as mãos), mobilidade física - velocidade, agilidade e equilíbrio (levanta, caminha 2,44m e volta a sentar), flexibilidade dos membros superiores (alcançar atrás das costas com as mãos) e resistência aeróbica (andar seis minutos). A bateria de testes foi aplicada antes do início das aulas e no fim do programa após três meses. Os grupos foram semelhantes em relação a idade, IMC, renda familiar e anos de escolaridade. RESULTADOS: Ao longo dos três meses, foram acompanhadas 30 mulheres em cada grupo; perda amostral de 18,9%. Observou-se no grupo da hidroginástica um melhor desempenho em todos os pós-testes, quando comparados com os resultados do próprio grupo no pré-teste e com o controle no pós-teste (p < 0,05). CONCLUSÃO: Concluiu-se que a prática de hidroginástica para mulheres idosas sem exercícios físicos regulares contribuiu para a melhoria da aptidão física relacionada à saúde.

Heart transplantation (HTx) is considered an efficient and gold-standard procedure for patients with end-stage heart failure. After surgery, patients have lower aerobic power (VO2max) and compensatory hemodynamic responses. The aim of the present study was to assess through a systematic review with meta-analysis whether high-intensity interval training (HIIT) can provide benefits for those parameters. This is a systematic review with meta-analysis, which searched the databases and data portals PubMed, Web of Science, Scopus, Science Direct and Wiley until December 2016 (pairs). The following terms and descriptors were used: "heart recipient" OR "heart transplant recipient" OR "heart transplant" OR "cardiac transplant" OR "heart graft". Descriptors via DeCS and Mesh were: "heart transplantation'' OR "cardiac transplantation". The words used in combination (AND) were: "exercise training" OR "interval training" OR "high intensity interval training" OR "high intensity training" OR "anaerobic training" OR "intermittent training" OR "sprint training". The initial search identified 1064 studies. Then, only those studies assessing the influence of HIIT on the post-HTx period were added, resulting in three studies analyzed. The significance level adopted was 0.05. Heart transplant recipients showed significant improvement in VO2peak, heart rate and peak blood pressure in 8 to 12 weeks of intervention.

Background and objective: Post-exercise hypotension, the reduction of blood pressure after a bout of exercise, is of great clinical relevance. Resistance exercise training is considered an important contribution to exercise training programs for hypertensive individuals and athletes. In this context, post-exercise hypotension could be clinically relevant because it would maintain blood pressure of hypertensive individuals transiently at lower levels during day-time intervals, when blood pressure is typically at its highest levels. The aim of this study was to compare the post-exercise cardiovascular effects on Paralympic powerlifting athletes of two typical high-intensity resistance-training sessions, using either five sets of five bench press repetitions at 90% 1 repetition maximum (1RM) or five sets of three bench press repetitions at 95% 1RM. Materials and Methods: Ten national-level Paralympic weightlifting athletes (age: 26.1 ± 6.9 years; body mass: 76.8 ± 17.4 kg) completed the two resistance-training sessions, one week apart, in a random order. Results: Compared with baseline values, a reduction of 5–9% in systolic blood pressure was observed after 90% and 95% of 1RM at 20–50 min post-exercise. Furthermore, myocardial oxygen volume and double product were only significantly increased immediately after and 5 min post-exercise, while the heart rate was significantly elevated after the resistance training but decreased to baseline level by 50 min after training for both training conditions. Conclusions: A hypotensive response can be expected in elite Paralympic powerlifting athletes after typical high-intensity type resistance-training sessions.

Purpose: The goals of the study were: a) to compare the way that two types of active video games (AVG) influenced physical effort and motivation in young adults; b) to compare direct and indirect instruments and use an indirect instrument (heart rate analysis) as a practical tool to verify physical effort in AVGsMethods: Methods. Initially, 16 healthy but physically inactive young adult males with no AVGs experience took part in the randomized control trial. After the baseline assessments of blood pressure (BP), heart rate (HR), and aerobic capacity (AE), the participants were randomized into two groups: structured AVG (n = 6) and unstructured AVG (n = 7) (3 dropouts). They played 3 sessions a week, during 6 weeks. Direct and indirect metabolic measurements were made. To compare direct and indirect AE, Student t-test was used for related samples. Changes (group × time) in HR, perceived exertion (PE), calculated energy expenditure (EE), calculated metabolic equivalent (MET), and motivation (points) were assessed with the two-way analysis of varianceResults: There were no differences between direct and indirect AE (36.0 ± 5.2 vs 33.9 ± 6.0 ml/kg/min: unstructured; 39.0 ± 5.9 vs 37.7 ± 5.9 ml/kg/min; p > 0.05). No differences were observed in maximal HR, PE, or motivation (p > 0.05). Statistically significant differences referred to average HR, MET, and EE over the sessions (p < 0.05). HR and EE values were higher in structured than in unstructured AVGsConclusions: HR and EE responses of structured AVGs turned out higher than those of unstructured AVGs, and the measurements proved efficient to analyse physical effort in AVGs in a long-term perspective
