简要总结
Anaerobic power and capacity are essential in many human activities, especially during sports practice that demand a high strength and power of the limbs. Transcranial direct current stimulation is a noninvasive technique that can modulate motor brain areas involved in motor functions and has the potential to optimize muscle capacity. However, their effects on mechanical power are lacking.
This study aims to investigate the effects of transcranial direct current stimulation (tDCS) on mechanical power in healthy subjects.
详细描述
In this study, a randomized, crossover, double-blind, placebo-controlled experimental design will be used. The 50 participants will be randomized into two groups: (1) Anodal tDCS(real) and (2) Sham tDCS. A single session of anodal and sham tDCS will be performed on each task (pre and post-jump test).
All evaluations will be performed by a single researcher who, like the participants, will not know which stimulation group will be participating. Subjects who agree to the conditions and sign the consent form may participate in the study. Participants who meet the eligibility criteria will be included in the study.

结局指标
主要结局
Mean anaerobic power
时间窗: Pre and Post-test (immediately after tDCS)
Mean anaerobic power will be evaluated by assessing the ground reaction forces (GRF) and the number of jumps in each test by means of the kinetic analysis of the 60-second vertical jump test (Bosco's Test).
次要结局
- Fatigue index(Pre and Post-test (immediately after tDCS))
- Peak anaerobic power(Pre and Post-test (immediately after tDCS))
- Rating of perceived exertion(Post-test (immediately after tDCS))
