Transcranial direct current stimulation does not improve countermovement jump performance in young healthy men. J Strength Cond Res 35 (10): 2918–2921, 2021—The main purpose of this study was to report the effects of transcranial direct current stimulation (tDCS) on countermovement jump (CMJ) performance in young healthy men. Seventeen healthy male subjects volunteered for the study (age: 22.4±2.6 years; body mass: 71.8±8.7 kg; height: 174.6±5.9 cm; and CMJ height: 36.8±6.3 cm). After a familiarization session, subjects underwent 3 experimental conditions, 7 days apart, in a randomized, double-blinded crossover design: anodal, cathodal, and sham tDCS. The stimulation was applied over the dorsolateral prefrontal cortex for 15 minutes. During experimental sessions, subjects completed …
