Background: Vitamin D is well known for its role in calcium homeostasis and bone metabolism. In addition 25 (OH) vitamin D3 (25OHD3) deficiency is correlated with muscle pain and weakness, hence there is increasing interest in optimal 25OHD3 levels for athletes. We investigated the prevalence of 25OHD3 deficiency and the ethnical variation in 25(OH)D concentrations among professional soccer players in the winter season.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
