Therefore, start performance should depend on self-control strength. It was expected that momentary depletion of self-control strength (ego depletion) would slow down the initiation of a sprint start, resulting in impaired reaction times. N = 37 participants performed three sprint starts at T1 and the average reaction times were measured with a foot-pressure release system attached under the starting block (in ms). Next, participants were randomly assigned to a depletion or a non-depletion condition and self-control strength was experimentally manipulated by applying the transcription task. Following the depletion manipulation, participants performed another series of three sprints (T2). The results of a mixed between (ego depletion: yes vs. no) within (T1 vs. T2) ANOVA supported the hypothesis as average reaction times in the depletion condition significantly increased from T1 (M = 0.35, SD = 0.03) to T2 (M = 0.38, SD = 0.04), F(1, 35) = 6.77, p = .01, η2p = .16. Average reaction times in the non-depletion condition did not differ significantly between T1 (M = 0.36, SD = 0.03) and T2 (M = 0.35, SD = 0.04), F(1, 35) = 0.47, p = .50, η2p = .01. In line with the hypothesis, higher levels of self-control strength were associated with quicker movement initiations. Therefore, improving self-control strength may serve as a buffer against the negative effects of ego depletion on performance.
