Effects of Transcranial Direct Current Stimulation on Cycling Time Trial Performance and Prefrontal Cortex Activation

Background: Transcranial direct current stimulation (tDCS) is a neuromodulatory technique that delivers low levels of constant via scalp electrodes to specifically targeted areas the brain. The effects tDCS on whole-body exercise performance has been interest in recent literature. purpose investigation was investigate if tDCS, administered Halo Sport, influences time trial trained cyclists, and changes are associated with prefrontal cortex (PFC) activation and/or muscle oxygenation (SmO2). Methods: Twelve recreationally cyclists volunteered participate crossover study design involving two 10-kilometer trials following 20 min or sham condition. Results: t-tests showed there no significant difference (time completion) physiological measures (blood lactate (BL) concentration, heart rate (HR), SmO2, PFC oxygenation) between conditions. Conclusions: These results indicate application Sport does not induce related parameters during cycling trial.
