Differences in Handgrip Strength-Endurance and Muscle Activation Between Young Male Judo Athletes and Untrained Individuals.

The aim of this study was to compare strength-endurance handgrip performance and muscle coactivation between judo athletes and untrained young males. The sample was 38 judo athletes and 38 untrained young males, between 12 and 15 years-old. Maturational status was evaluated by age at peak height velocity.

Can interoceptive accuracy influence maximal performance, physiological and perceptual responses to exercise?

Interoception has been shown to influence self-regulation of effort and perceived exertion during exercise. However, whether interoceptive accuracy influences submaximal and maximal exercise performance, as well as psychophysiological responses to it, remains elusive. We assessed poor (n = 15) and good (n = 17) heartbeat perceivers young men accordingly with their interoceptive accuracy.

Can Transcranial Direct Current Stimulation Modulate Psychophysiological Response in Sedentary Men during Vigorous Aerobic Exercise?

This study evaluated whether transcranial direct current stimulation (tDCS) could change physiological and psychological responses during vigorous exercise with a constant load. 13 sedentary males (23.0±4.

[Acute effect of vigorous aerobic exercise on the inhibitory control in adolescents].

Objective:: To assess the acute effect of vigorous aerobic exercise on the inhibitory control in adolescents.

Methods:: Controlled, randomized study with crossover design. Twenty pubertal individuals underwent two 30-minute sessions: (1) aerobic exercise session performed between 65% and 75% of heart rate reserve, divided into 5 min of warm-up, 20 min at the target intensity and 5 min of cool down; and (2) control session watching a cartoon.
