Brief Summary
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.

Conditions
Outcome Measures
Primary Outcomes (1)
Mean anaerobic power
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).
Pre and Post-test (immediately after tDCS)
Secondary Outcomes (3)
Peak anaerobic power
Pre and Post-test (immediately after tDCS)
Fatigue index
Pre and Post-test (immediately after tDCS)
Rating of perceived exertion
Post-test (immediately after tDCS)
Study Arms (2)
tDCS (anodal)
ACTIVE COMPARATORtDCS: 20 minutes, 2mA, over the motor cortex representation of lower limbs.
tDCS (sham)
SHAM COMPARATORtDCS: 20 minutes (but 30s ON), 2mA, over the motor cortex representation of lower limbs.
Interventions
Transcranial direct current stimulation (tDCS) is a noninvasive brain stimulation (NIBS) technique that has been investigated for the management of various health conditions. However, its ergogenic effect still has controversial results.
