Many College Basketball Athletes Have Low Vitamin D Levels
Vitamin D is essential for strong bones, because it helps the body use calcium from the diet. A recent study has found that college athletes participating in indoor sports may be vitamin D deficient, which could increase the risk of injury. The study also found that supplementation with 10,000 IU of vitamin D could help improve vitamin D levels.
Participants in the study included twenty college age students who played college basketball. Baseline levels of vitamin D were measured, and 65% of the participants were found to be vitamin D deficient. The highest levels of deficiency were found in participants with darker skin pigmentation, Thirteen of the participants were given 10,000 IU of vitamin D, 5 were given 5,000 IU of vitamin D, or and 2 were given no vitamin D for 5 months. The amount of vitamin D given was based on baseline levels.
The researchers found that participants in the high dose group saw an average increase of 35 nmol/L in vitamin D levels, compared to an average decrease of <span> </span>9.3 nmol/L in the low dose group and an average decrease of 41.6 nmol/L in the no dose group. 69% of the participants in the high dose group achieved sufficient vitamin D status, 8% achieved optimal status, and 23% remained insufficient. In comparison, 75% of the participatns in the low dose group remained at sufficient status and 25% fell to insufficient status.
The study was conducted by researchers from George Mason University. It was published on January 31, 2020 in the journal Nutrients.
