In addition to observing changes in corticospinal excitability in those receiving anodal stimulation, the researchers found that their ratings of perceived exertion were also lower. In other words, cyclists who received anodal stimulation biked longer before quitting than did those under the cathodal and sham conditions. They found that placing the anodes over both motor cortices augments endurance performance. In an October 2017 article titled “Bilateral extracephalic transcranial direct current stimulation improves endurance performance in healthy individuals,” Angius and co-authors used transcranial direct current stimulation (tDCS), a form of brain stimulation, to improve endurance in 12 healthy, active adults during 10-minute cycling sessions.īoth before and after tDCS, the researchers assessed neuromuscular performance by measuring time to task failure among participants engaged in cycling sessions. Recently, the ability of brain stimulation to enhance sports performance has become an expanding focus of academic study. Common legal ergogenic aids include multivitamin supplements and hypoxic training. Consequently, professional athletes take great interest in ergogenic aids, which refer to any technique or substance used to enhance performance. The difference in performance between two elite athletes amounts to less than one percent. In the ultra competitive world of professional sports, victory is measured in fractions of time and distance.
