简要总结
The study aims to compare the effects of tDCS applied on the dorsolateral prefrontal cortex (dlPFC) vs sham on the neuromuscular system. Two types of athletes will benefit from stimulation: jumper and cyclists. Short and long term effects are assesed by electromyographic records, experimental tasks and self-rated scales.
详细描述
Transcranial direct current stimulation is a technique of noninvasive brain stimulation which delivers a electrical current to the scalp to modulate the neuronal activity. Depending on the polarity of stimulation, tDCS induces a neural hyperexcitability (with anode) or hypoexcitability (with cathode) of the target area.
Due to its neuromodulatory action, ease of use and low safety, tDCS can be used as a potential treatment but also as an investigative tool in neurophysiology. Thus, studies have shown a beneficial effect of tDCS on cognitive and motor functions. Nevertheless, studies conducted on motor performance and the reduction of neuromuscular fatigue show disparate results. It is impossible to conclude whether tDCS allows for improved performance and is a means of doping.
With a prospective, sham-controlled, crossover, double-blind design, this study aims to evaluate the effect of tDCS on neuromuscular fatigue resistance during explosive (jumping) and endurance (cycling) exertion.
This study is divided into two parts:
- Part A: jumping group
- Part B: cycling group.
