Abstract

This pilot cross-sectional study was conducted to assess vitamin D status and body composition of collegiate indoor female volleyball players at Rice University in Houston, TX. Serum 25-hydroxyvitamin D [25(OH)D] concentrations and body composition was determined using air displacement plethysmography. Participants completed a 24-hour food record, vitamin D food frequency questionnaire, and sunlight habit questionnaire to assess dietary vitamin D intake and sunlight exposure habits. This study also piloted the use of La-Roche-Posay MyUV Patch to estimate ultraviolet light A (UVA) and ultraviolet light B (UVB) exposure. No significant relationship was found between vitamin D status, percent body fat, dietary vitamin D intake, or UVA and UVB exposure. However, the study did find that the majority of participants (64%) were vitamin D deficient or insufficient based on serum 25(OH)D. This study contributes to the knowledge of vitamin D status of indoor college athletes and can serve as a template for future studies.
