Effect of transcranial direct current stimulation on the psychomotor, cognitive, and motor performances of power athletes
Abstract In sports science, transcranial direct current stimulation (tDCS) has many unknown effects on neuromuscular, psychomotor and cognitive aspects. Particularly, its impact on power performances remains poorly investigated. Eighteen healthy young males, all trained in a jumping sport (parkour)...
