Vitamin D deficiency information
Vitamin D deficiency had been shown to increase the risk of sports injuries.
Vitamin D is produced by the skin when the skin is exposed it is to the sun’s UVB rays.
Living further from the equator, less tie in the sun, smog and the use of sunscreen can contribute to vitamin D deficiency.
Vitamin D helps you to absorb calcium.
Vitamin D is essential for bone growth, density, and remodeling.
Milk was initially fortified with vitamin D in the 1930’s when it was noted that vitamin D deficiency caused bone problems such as Rickets.
Vitamin D deficiency and bone injury
Prior studies have shown that vitamin D deficiency has been associated with increased bone injury.
Vitamin D deficiency increases bone turnover, which increases the risk for a bone injury.
A study published in Osteoporosis International showed that military recruits who had vitamin D deficiency had a higher risk of stress fracture. “Stress fractures are a common overuse injury in military recruits, including Royal Marine (RM) training in the UK. RM training is recognized as one of the most arduous basic training programs in the world.”
Vitamin D deficiency and muscle injury

A recent study from the Hospital for Special Surgery showed that there was a higher risk of muscle injury in athletes who had vitamin D deficiency.
“a significantly higher prevalence of lower extremity muscle strain and core muscle injury in those who had low vitamin D levels. Fourteen study participants reported missing at least one game due to a strain injury, and 86% of those players were found to have inadequate vitamin D levels.”
Vitamin D deficiency and athletic performance
One study published in Sports Health showed,
“There is a strong correlation between vitamin D deficiency and optimal muscle function.”
Increasing levels of vitamin D reduced inflammation and pain.
Vitamin D intake increased muscle protein, jump height and exercise capacity.
It is important to note that this study was small and additional research is needed. A study published in The International Journal of Sports Nutrition and Exercise Metabolism showed no difference in athletic performance of swimmers who were given vitamin D and were no had vitamin D deficiency.
Athletic performance and dietary counseling
A study from International Journal of Sports Nutrition and Exercise Metabolism suggested,
“Receiving dietary counseling seemed to result in better-informed choices with respect to the use of nutritional supplements related to performance, recovery, and health.”
