Low-intensity aerobic training combined with blood flow restriction (LI + BFR) has resulted in increases in aerobic and neuromuscular capacities in untrained individuals. This strategy may help cyclists incapable of training with high intensity bouts or during a rehabilitation program. However, there is a lack of evidence about the use of LI + BFR...

This study aimed to analyze performance, time structure, technical actions, and perceptual responses of Brazilian jiu-jitsu athletes during matches of varied duration. For this, 10 athletes were analyzed in matches of varied duration (2-min, 5-min, 8-min and 10-min). Physical tests (reaction time, maximal isometric handgrip strength, grip strength...

The aim of this study was to analyze physiological responses in Brazilian jiu-jitsu (BJJ) athletes during matches of varied duration. To this end, 10 athletes (age: 29±5 years old, body mass: 77.5±6.3 kg, body fat: 10.0±5.2%, systematic BJJ practice: 10±2 years) were analyzed in matches of varied duration (2-min, 5-min, 8-min and 10-min). Blood col...

The aim of this study was to compare the effects of exercise intensity on appetite control: relative energy intake (energy intake minus the energy expenditure of exercise; REI), hunger scores, and appetite-regulating hormones in men and women. Eleven men and 9 women were submitted to 4 experimental sessions: high-intensity intermittent all-out exer...

Because physical activity is a powerful strategy to prevent, treat and rehabilitate general health,1 the topic of sports and exercise medicine (SEM) is gaining attention among those who decide the undergraduate curriculum in Brazil.2 In Brazil, SEM is a multidisciplinary and interdisciplinary clinical and academic medical specialty, which can also...

The aim of this study was to analyze performance, time structure, technical actions, and perceptual responses in Brazilian jiu-jitsu athletes during a simulated competition. For this purpose, 10 athletes were analyzed in a simulated competition (four matches of 10 min). Physical tests and scales of the perception of effort and recovery were applied...

The aim of this study was to evaluate the performance, as well as neuromuscular activity, in a strength task in subjects with different training backgrounds. Participants (n = 26) were divided into three groups according to their training backgrounds (aerobic, strength or mixed) and submitted to three sessions: (1) determination of the maximum oxyg...

This study aimed to analyze the effect of the time interval after high-intensity aerobic exercise on strength performance in individuals with different training backgrounds. Participants (n = 27) were divided into three groups according to their training backgrounds (aerobic, strength or concurrent) and submitted to eight sessions: (1) determinatio...
