초록

Objective: This study systematically analyzed the effects of kinematic factors on golf clubhead speed through a meta-analysis to provide quantitative evidence for golf performance enhancement. Method: A comprehensive literature search was conducted across multiple databases from January 2000 to June 2025. Following PRISMA guidelines, 9 studies were included after systematic screening from 452 initially identified studies. Effect sizes (ESr) were calculated using correlation coefficients with Fisher's Z transformation. Subgroup analyses examined different kinematic factors, and meta-regression analysis assessed the moderating effect of gender composition. Results: The overall effect size of kinematic factors on golf clubhead speed was moderate (ESr = .321). Individual factor analysis revealed that maximum trunk rotational velocity during downswing showed the largest effect size (ESr = .530), followed by X-factor stretch (ESr = .518) and X-factor (ESr = .471). Maximum hip rotation velocity during downswing demonstrated smaller effect sizes (ESr = .010 respectively). Meta-regression analysis indicated no significant gender moderation effect (p > .05). Publication bias assessment showed no significant bias with fail-safe N = 502. Conclusion: This meta-analysis demonstrates that kinematic factors significantly contribute to golf clubhead speed, with dynamic rotational movements being more important than simple rotational velocities. The findings emphasize the critical role of X-factor stretch and trunk rotational velocity in power generation. These results provide scientific evidence for developing training strategies focused on pelvis-shoulder separation dynamics and core rotational power enhancement, applicable across genders with individual adjustments for physical characteristics.
