摘      要：Purpose The primary aim of this study is to determine the prevalence of vitamin D deficiency and insufficiency among Asian athletes participating in indoor and outdoor sports in equatorial *** aims are to examine the relationship between vitamin D status and skeletal muscle strength and performance,and bone *** Serum 25(OH)D concentrations were determined in 95 indoor and outdoor athletes across various *** muscle strength and performance were assessed using the isometric mid-thigh pull(IMTP),drop jump test and 30 m sprint *** Mineral Density(BMD)was measured using Dual-energy X-ray Absorptiometry(DXA).Results Mean serum 25(OH)D concentrations were 28.6±8.9 ng/mL among indoor,and 39.2±13.2 ng/mL among outdoor sport athletes respectively(P0.05).More indoor sport athletes(62%)had insufficient vitamin D compared to outdoor sport athletes(30%)(P0.05).Outdoor sport athletes exhibited significantly greater peak force generation than indoor sport athletes(2079±470 N vs.1869±546 N,P=0.027).Other markers of muscle function were not significantly different between *** and outdoor sport athletes did not have significantly different BMDs although none of the athletes studied presented with poor *** who were deficient in vitamin D had significantly lower BMD compared to athletes with sufficient vitamin D(P=0.01).Conclusion Forty-seven percent of Singaporean athletes studied had suboptimal vitamin D *** monitoring of vitamin D levels among indoor sport athletes should be in place to ensure optimal health and performance.
