Summary

The goal of this study is to determine whether Vitamin D supplementation improves strength and bone density, and reduces the risk of injury in collegiate athletes.

Detailed description

Vitamin D is a hormone that is important for bone and muscle health. As such, not having enough vitamin D in your body is associated with increased risk of injury and reduced health and athletic performance. It is often recommended that individuals who have low levels of vitamin D take vitamin D supplements. However, the effects of vitamin D supplementation on health and strength gains in collegiate athletes are not known. The goal of this study is to determine whether vitamin D supplementation increases strength and bone density, while reducing the risk of injury in collegiate athletes. Fasting vitamin D concentrations will be measured and athletes will be supplemented daily with Vitamin D for 8-12 weeks. The amount of supplementation will depend on whether the athlete is categorized as sufficient (\>30ng/ml), insufficient (20-35ng/ml), or deficient (\<20ng/ml). Vitamin D concentrations, strength, bone density, and injury risk will be assessed before and after the intervention period.
