Transcranial direct current stimulation: No effect on aerobic performance, heart rate, or rating of perceived exertion in a progressive taekwondo-specific test
(Transkranielle Gleichstromstimulation: Keine Auswirkung auf die aerobe Leistungsfähigkeit, die Herzfrequenz oder die Bewertung der wahrgenommenen Anstrengung in einem progressiven taekwondospezifischen Test)
Purpose: To investigate the effects of anodal transcranial direct current stimulation (a-tDCS) on the aerobic performance, heart rate (HR), and rating of perceived exertion (RPE) of highly trained taekwondo athletes. Methods: Twelve (8 men and 4 women) international/national-level athletes received a-tDCS or sham treatment over the M1 location in a randomized, single-blind crossover design. The stimulation was delivered at 1.5 mA for 15 min using an extracephalic bihemispheric montage. Athletes performed the progressive-specific taekwondo test 10 min after stimulation. HR was monitored continuously during the test, and RPE was registered at the end of each stage and at test cessation. Results: There were no significant differences between sham and a-tDCS in time to exhaustion (14.6 and 14.9, respectively, P=.53, effect size=0.15) and peak kicking frequency (52 and 53.6, respectively, P=.53, effect size=0.15) or in HR (P>.05) and RPE responses (P>.05). Conclusions: Extracephalic bihemispheric a-tDCS over M1 did not influence the aerobic performance of taekwondo athletes or their psychophysiological responses, so athletes and staff should be cautious when using it in a direct-to-consumer manner.
