Association between tennis training experience and executive function in children aged 8–12

Abstract

Cognitively engaging activities have been shown to facilitate the improvement of executive functions in children. However, a limited number of studies have investigated whether the relationship between dose parameters of physical activities and executive functions, and heterogeneity exists. In the present study, we aim to explore the association between tennis training experience and executive functions in children. Sixty children between the ages of 8 and 12 were recruited in this study and were allocated to the short-term (ST) group (<12 months, n = 30) and the long-term (LT) group (more than 12 months, n = 30). The abilities of inhibitory control, cognitive flexibility, and working memory were measured by the Stop-signal task, Switching task, and N-back task, respectively. There was no significant group difference in either the accuracy or reaction time of the Stop-signal task. No significant difference between the groups' accuracy in the Switching task was observed. However, the LT group presented a shorter reaction time than the ST group (731.69 ± 149.23 ms vs. 857.15 ± 157.99 ms, P < 0.01) in the Switching task. Additionally, training experience was positively associated with the reaction time of the Switching task. As for the N-back task, in comparison with the LT group, the ST group showed a longer reaction time (711.37 ± 168.14 ms vs. 164.75 ± 635.88 ms, P < 0.05). Moreover, training experience was also positively associated with the reaction time of the N-back task. But there was no significant group difference in the accuracy of the N-back task. In conclusion, children trained for over 1 year have better performance in cognitive flexibility and working memory than those trained in <1 year; thus, tennis experience is positively associated with executive functions.
