Resumo: The search for increased performance and physical performance are linked to the use of ergogenic resources. The vertical jump is one of the measures commonly used to evaluate the performance of lower limbs in athletes. Transcranial direct current stimulation (tDCS) is a noninvasive, safe, economically viable technique that can modulate cortical excitability, which can influence the increase in the performance of athletes in general. The aim of this study was to investigate whether the use of tDCS on the motor cortex (M1) results in an improvement in the performance of soccer players. This is a cross-sectional study where 27 players were randomized into three groups: Active tDCS group (n=9); Sham group (n=9) and control group (n=9). Stimulation was applied at an intensity of 2 mA for 15 minutes using a bi-hemispheric cephalic mount. Athletes performed the vertical jump before and after tDCS. The subjects' heart rate (HR) was monitored before and after the vertical jump. After the jump, the subjective perception of effort (RPE) was recorded. Visual pain scale (VAS) and subjective recovery scale (RPE) were monitored before and after tDCS. No differences were found in any of the performance variables analyzed (p > 0.05) nor in the responses of HR (p > 0.05), PSE (p > 0.05), VAS (p > 0.05) and EPR (p > 0.05) between groups. The tDCS in M1 did not change the performance of the vertical jump and there was no improvement in the subjective scales. Additionally, new studies should be developed with stimulus intensities in different cortical areas and different sports modalities.
