More than half of college football athletes have inadequate levels of vitamin D: Vitamin D deficiency linked to muscle injuries -- ScienceDaily
The study, presented at the American Academy of Orthopaedic Surgeons Annual Meeting on March 16, included 214 college athletes who took part in the 2015 combine. Baseline data was collected, including age, body mass index (BMI), injury history, and whether they had missed any games due to a lower extremity muscle strain or core muscle injury.
The average age of the athletes was 22. Their vitamin D levels were determined with a blood test. Levels were defined as normal (? 32 ng/mL), insufficient (20 -- 31 ng/mL), and deficient (< 20 ng/mL).
A total of 126 players (59%) were found to have an abnormal serum vitamin D level, including 22 athletes (10%) with a severe deficiency. Researchers found 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.
