The relationship between serum vitamin D, bone mineral density, and injury in collegiate acrobatics and tumbling athletes

Background:Medical staff for indoor aesthetic sports such as acrobatics and tumbling (A&T) is often concerned with athletes’ bone mineral density (BMD), serum vitamin D (SvD), and associated injury risks. Aim:To evaluate the relationship between BMD, SvD, and injury among A&T athletes. Methods:42 (19 tops, 23 bases) female A&T athletes aged 19.6 (±1.17) years participated. Two samples of SvD were taken. Injury and BMD data were provided by support staff. Bivariate and multivariate analysis assessed relationships between and among variables. Results:Participants experienced a decrease in SvD (6.093 ± 10.973). Spine BMD was significantly higher in bases compared to tops (p = 0.039). BMD and SvD did not differ based on injuries sustained. Conclusion:Relationships between SvD, BMD, and injury were not identified. Positional differences in BMD may be related to the demands of each role. Participants possessed low SvD and high BMDs, which may provide useful information for medical staff.
