Effects of tDCS on Anaerobic Power of Lower Limb Muscles

Effects of tDCS on Mechanical Power of the Leg Extensor Muscles of Healthy Subjects

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.

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.

Inclusion Criteria:

• Healthy subjects with no complaints of pain or any kind of discomfort in the musculoskeletal system

Exclusion Criteria:

• Musculoskeletal or neurological disorder
• Under medication
• Previous treatment with tDCS
