Introduction
RPE
SECONDARY, CORTEX
Transcranial direct current stimulation (tDCS) is a neuromodulation technique that delivers a constant, low-intensity flow of electric current to the scalpStimuli in the motor cortex (M1) region can directly influence sport performanceHowever, some studies failed to identify any acute stimulation effect on M1. In amateur runners they showed no improvement in performance with 15 min of 2 mA stimulationDuring running, the amplitude of individual muscle activation and groupings can vary. Incomplete muscle activation occurs consistently during exhaustive and high-resistance exerciseThe present study’s main objective was to explore an anodic electrode’s effects on the M1 and the performance and RPE in 5000 m runners. The secondary objective was to investigate the effect of tDCS on the knee extensor muscles’ peak torque (Pt) that are fundamental for runners. Therefore, we hypothesized that tDCS at an intensity of 2 mA would improve running times after a 20 min application.
