The beneficial effects of game-based exercise using age-appropriate tennis lessons on the executive functions of 6-12-year-old children.

This study evaluated the effects of two different types of tennis lessons-those involving a technique-based approach (TBA) and those involving a game-based approach (PLAY+STAY [P+S])-on the executive functions (EFs) of junior tennis players. Eighty-one tennis players (6-12 years old) were recruited and assigned to one of three groups: TBA, P+S, or watching TV (CONT). Subjects completed evaluations of EFs (inhibitory control, working memory, and cognitive flexibility) before and after 50min programs. The overall score for EFs improved significantly for both the P+S and TBA groups but not for the CONT group; indeed the CONT group showed no improvement in overall EFs. Furthermore, the overall EF score improved more for P+S participants than for those in TBA. Looking at components of EFs, the pattern for inhibitory control reflected the pattern for the overall EF index: Improvement in the P+S and TBA groups but not in the CONT group. Only the P+S group improved in working memory. Thus, playing tennis and practicing isolated tennis skills both improved EFs of junior players more than did watching TV, and game-based tennis lessons seem to hold more promise for improving EFs than drills of tennis skills.
