Previous research documented differences in executive functions between elite athletes in different sports. It was argued that athletes in sport disciplines with higher cognitive demands (i.e., open-skill) show better executive functions than athletes in less cognitively challenging sport disciplines (i.e., closed-skill). In the current study, we aimed at detecting differences in executive functions between elite athletes in open-skill versus closed-skill sports and questioned the role of their total involvement in these sports until the age of 18 on executive functions. Seventy-five elite athletes (45 males and 30 females; Mage = 23.03 ± 4.41 years) from various sports were classified as open- or closed-skill athletes based on the sport they currently competed in. The athletes conducted a series of neuro-psychological tests measuring working memory, inhibition, and cognitive flexibility (Design Fluency test, Trail Making test, Flanker task, and a 2-back task). Retrospective interviews assessed athletes' sport involvement in open-skill and closed-skill sports until the age of 18. MANCOVAs revealed that athletes in open-skill sports performed better on measures of working memory and cognitive flexibility. Generalized Linear Models displayed that elite athletes in closed-skill sports, with greater involvement in open-skill sports until the age of 18, performed better during working memory and cognitive flexibility tasks. The results indicate that extensive time spent in open- and closed-skill sports can affect executive functions in elite athletes. A high involvement in open-skill sports proved to be beneficial for executive functions, in particular for elite athletes in closed-skill sports. These findings suggest that experiences in cognitively demanding sports may cause benefits for the development of executive functions. Highlights • 75 Elite athletes completed 4 tests measuring core executive functions (EF). • Retrospective interviews investigated sport involvement until age 18. • Open-skill athletes outperformed closed-skill athlete on certain EF measures. • High Involvement in open-skill sports benefits EF of closed-skill athletes.
