摘要: ABSTRACT Ciccone, AB, Fry, AC, Emerson, DM, Gallagher, PM, Herda, TJ, and Weir, JP. Effects of transspinal direct current stimulation on cycling perception effort time to exhaustion. J Strength Cond Res 35(2): 347-352, 2021-In the past decade, researchers have investigated efficacy (tsDCS) central nervous system afferent neuron function in humans. Recently, data suggested it may be possible for such tsDCS-induced changes neuromuscular enhance performance. This study used noninvasive thoracic spine tsDCS determine if performance could modulated by tsDCS. In 3 different conditions, anodal, cathodal, sham, subjects cycled at 80% their maximal aerobic capacity until exhaustion reported rating perceived exertion (RPE) every minute. From this period, we compared RPE responses over first minutes There was no significant difference between anodal (408 ± 121 seconds), cathodal (413 168 sham (440 189 seconds) conditions (p = 0.58). from 1-3 (collapsed across time) (12.9 2.4 arbitrary units (AUs)), (13.3 2.2 AUs), 2.1 AUs) 0.51). These suggest condition did not influence or during high-intensity cycling. Therefore, lower abdominal montage delivering a density 0.071 mA·cm-2 20 likely does substantially improve work capacity. more research is needed investigate which methods human
