A large number of studies have described a positive relationship between physical exercise and cognition. Physical exercise can be divided into closed-skill exercise (CSE) and open-skill exercise (OSE) based on the predictability of the performance environment. It remains unknown whether either of these types of exercise is more beneficial for cognitive function. Therefore, the purpose of this meta-analysis was to evaluate the effect of OSE versus CSE on cognition. Eligible studies included cross-sectional studies and intervention studies that had a clear definition of OSE and CSE, and these were used to compare the cognitive performance differences between the two classes of exercise. A total of 15 cross-sectional studies and 4 intervention studies were included in this meta-analysis. Among the cross-sectional studies, the overall effect size for OSE versus CSE was 0.304 (95% confidence interval (CI) (−0.097, 1.213); p &lt; 0.05). Further subgroup analysis showed that the overall effect size for OSE versus CSE was 0.247 for inhibition and 0.360 for cognitive flexibility (both p &lt; 0.05). In contrast, no significant differences between the two exercise modes were observed in the intervention studies. In particular, there were no significant differences in visuospatial attention or in processing speed between the two exercise modes. Taken together, these results suggest that OSE is superior to CSE, especially for executive function, according to the 15 cross-sectional studies examined. However, data from the intervention studies indicate that OSE is not superior. Therefore, additional well-designed, long-term intervention studies are needed to elucidate the potential efficacy of OSE in all populations.
