Experimental protocol
The athletes visited the Physical Education Department—athletics track at UFS to perform a familiarization session on the procedure and data collection. Initially, we collected the peak torque in three trials, with 30 s of recovery between them. The tDCS was performed for 20 min at an intensity of 2 mA. After a 10-min warm-up, the runners started a 5000-m race on an official athletic track. At the end of the run, there was a 3-min rest, after which the peak torque was reevaluated. The survey design can be seen in (Fig. Experimental design—
