Table Tennis as a Sustainable Health Intervention: A Meta-Analysis of Its Effects on Balance and Cognitive Functions

Background: Physical inactivity is linked to falls, cognitive decline, and reduced independence, underscoring the need for accessible interventions that enhance balance and cognitive functions. In this context, sustainability refers to affordability, accessibility, feasibility, and potential for long-term adherence. Table tennis, an open-skill sport requiring motor coordination and cognitive engagement, may help improve balance and cognitive functions. This meta-analysis synthesized available evidence to investigate the effects of table tennis interventions on balance and cognitive functions. Methods: Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 guidelines and PROSPERO registration, six electronic databases were searched. A meta-analysis was conducted with 14 randomized controlled trials comprising 1565 participants in total. Additionally, subgroup analyses were conducted based on intervention participants, health status, intervention duration, and session length. Results: Pooled analyses showed that individuals who received table tennis interventions demonstrated significantly improved balance (standardized mean difference SMD = 0.78, 95% confidence interval CI 0.57, 0.98) and cognitive (SMD = 2.05, 95% CI 1.27, 2.83) functions than those who did not. Subgroup analyses indicated consistent benefits across different age groups and health statuses, along with larger cognitive function effects with longer interventions. Despite considerable heterogeneity across studies and limited evidence for some subgroups, sensitivity analyses supported the robustness of the results. Conclusions: Table tennis appears to be a feasible and low-cost intervention that can effectively enhance balance and cognition functions, with potential applicability in community, educational, and rehabilitation settings. However, considering the observed heterogeneity and methodological limitations, the findings should be interpreted with caution.
