Elite team sport athletes demonstrate better response inhibition performance compared to semi-elite athletes (Heppe & Zentgraf, 2019), presumably as they have more experience with dynamic game contexts. However, whether this experience is related to effector-specific differences (i.e., feet in soccer, hands in basketball) has not yet been investigated. Therefore, the aim of the study was to study response inhibition tasks ('hand'; 'foot') in hand-dominated (basketball) and foot-dominated (soccer) athletes. We hypothesized that basketball athletes would show superior performance with the effector 'hand', whereas football athletes with the effector 'foot'. A total of 122 athletes (nbasketball = 63) performed a stop-signal task (Verbruggen et al., 2008), using both hands and feet. Response inhibition performance was assessed by calculating individual stop-signal reaction times (SSRT). To evaluate differences in SSRT, a 2 x 2 ANOVA (‘effector’; ‘group’) was conducted. Results indicate a main effect for ‘group’ (F(1,120) = 11.41, p < .01, ηp2 = .09), with better SSRT for soccer athletes, and a main effect for ‘effector’ (F(1,120) = 97.07, p < .01; ηp2 = .45), with superior response inhibition performance for 'hand'. No interaction effect was found (p > .05). Contrary to our expectations and surprisingly, we did not find superior performance in effector-specific tasks, but soccer athletes outperforming basketball athletes in both effectors. Re- and post-hoc analyses will elaborate on finding explanations for this, e.g., post-error-slowing, expertise levels, or strategies.
