Purpose: The recent observational study was clarified what the vitamin D supplementation is related to the physical performance of an athlete. However, RCTs, which have been reported so far, have not been concluded yet because every researcher shows a difference as for the impact of vitamin D supplementation on the physical performance. Also, there are many existing systematic considerations or meta analyses that were conducted targeting mainly the general public. Thus, there is a limit to evaluating the role of vitamin D as the improvement in physical performance of an athlete. Accordingly, this study is aimed to examine the influence of the Vitamin D supplement therapy in an athlete upon physical performance through meta analysis.
Method: A literature search was carried out the comprehensive retrieval by using MEDLINE, EMBASE, Cochrane Library. The integrated effect size of the collected research was analyzed by using statistical program R version 4.0.4 (Feb. 15, 2021). The effect size was distinguished in accordance with the guideline in Cohen’s d.
Results: Totally 7 RCTs were included in meta analysis. The effect size of physical performance in an athlete after vitamin D supplementation stood at 0.39, thereby having reflected the meaningful effect size. The significant effect size was shown in counter movement jump(0.89) and Peak Power(1.24) out of the muscle power in physical performance.
Conclusion: This meta analysis can be considered that the vitamin D supplementation has the impact on the counter movement jump and the Peak Power in an athlete’s physical performance. Nevertheless, the outcome needs to be interpreted carefully due to few number of usable RCTs and to the restrictions such as the research-based heterogeneity and the potential publication bias.
