Comparison of working memory performance in athletes and non-athletes: a meta-analysis of behavioural studies.
The relationship between sports expertise and working memory (WM) has garnered increasing attention in experimental research. However, no meta-analysis has compared WM performance between athletes and non-athletes. This study addresses this gap by comparing WM performance between these groups and investigating potential moderators. A comprehensive literature search identified 21 studies involving 1455 participants from seven databases, including PubMed, Embase, and ProQuest. Athletes primarily engaged in basketball, football, and fencing, while non-athletes included some identified as sedentary. The risk of bias assessment indicated low risk across most domains. Publication bias, assessed through a funnel plot and statistical tests, showed no significant evidence of bias. The forest plot, using a random effects model, revealed moderate heterogeneity. The overall effect size indicated a statistically significant, albeit small, advantage for athletes over non-athletes (Hedges' g = 0.30), persisting across sports types and performance levels. Notably, this advantage was more pronounced when athletes were contrasted with a sedentary population (Hedges' g = 0.63), compared to the analysis where the sedentary population was excluded from the non-athlete reference group (Hedges' g = 0.15). Our findings indicate a consistent link between sports expertise and improved WM performance, while sedentary lifestyles appear to be associated with WM disadvantages.
期刊介绍:
Memory publishes high quality papers in all areas of memory research. This includes experimental studies of memory (including laboratory-based research, everyday memory studies, and applied memory research), developmental, educational, neuropsychological, clinical and social research on memory. By representing all significant areas of memory research, the journal cuts across the traditional distinctions of psychological research. Memory therefore provides a unique venue for memory researchers to communicate their findings and ideas both to peers within their own research tradition in the study of memory, and also to the wider range of research communities with direct interest in human memory.
