Vitamin D deficiency cripples elite athletes, study finds
SAN DIEGO — More than half of college football athletes participating in the NFL Combine had inadequate levels of vitamin D, and this left them more susceptible to muscle injuries, according to a study at Hospital for Special Surgery.
"Vitamin D has been shown to play a role in muscle function and strength," stated Scott Rodeo, senior investigator and co-chief emeritus of the Sports Medicine and Shoulder Service at HSS. "While most prior studies have focused on the aging population as the group most likely to experience the harmful effects of inadequate vitamin D, few reports have looked at the impact on muscle injury and function in the high performance athlete."
Rodeo and colleagues set out to determine if there was a relationship between serum vitamin D levels and lower extremity muscle strains and core muscle injury, or "sports hernia," in college football players. The study included athletes participating in the National Football League Scouting Combine, where coaches, general managers and scouts evaluate top college football players hoping to make it into the big leagues.
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, 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. 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.
"Our primary finding is that NFL combine athletes at greatest risk for lower extremity muscle strain or core muscle injury had lower levels of vitamin D. This could be related to physiologic changes that occur to muscle composition in deficient states," Rodeo explained. "Awareness of the potential for vitamin D inadequacy could lead to early recognition of the problem in certain athletes. This could allow for supplementation to bring levels up to normal and potentially prevent future injury."
While the findings are significant for high performing athletes, there may be a message for the general population as well, according to Rodeo. Adequate vitamin D is essential for musculoskeletal structure, function and strength. But by some estimates, more than 40% of the U.S. population is deficient in vitamin D.
Sometimes called the "sunshine vitamin," it is produced by the skin when exposed to sunlight. Sun avoidance and the use of sunscreen may in part account for low vitamin D levels in the population. Milk and fortified foods, including orange juice and some cereals, can also provide vitamin D, but one would need to consume a large amount of these foods. When individuals are found to have a deficiency, vitamin D supplements are usually recommended.
"Although our study looked at high performance athletes, it's probably a good idea for anyone engaging in athletic activities to give some thought to vitamin D," Rodeo said. "Indeed, adequate levels of vitamin D are important to maintain good muscle and bone health in people of all ages."
AliveCor incorporates AI into consumer diagnostics offering
MOUNTAIN VIEW, Calif. – AliveCor on Thursday announced the U.S. release of Kardia Pro, an artificial intelligence-enabled platform for doctors to monitor patients for the early detection of atrial fibrillation.
“To manage heart disease and stroke risk, leading cardiologists want to see more than just ECGs from their patients,” stated Vic Gundotra, AliveCor CEO. “Kardia Pro tracks important measures of physiology like weight, activity and blood pressure, and, for the first time, AI technology is used to create a personal heart profile for each user, enabling user identification," he said. "The new platform enables doctors to be better doctors and patients to be more active participants in their own heart health, driving healthcare forward into the 21st century.”
The company also announced $30 million in new funding, led by Omron Healthcare and Mayo Clinic, fueling the company’s mission to improve the quality of care in the fight against heart disease and stroke. AliveCor will use the additional capital to accelerate innovations in heart health and continue the rapid expansion of the business.
“We are establishing new partnerships to redefine the role of technology in heart health as part of our Going for Zero mission," noted Ranndy Kellogg, Omron Healthcare CEO. "Partnering with AliveCor advances our path forward to build robust software programs that play a dynamic role in expanding heart health awareness, transforming the patient and caregiver dynamic and taking real steps toward eliminating heart attack and stroke.”
AliveCor’s AI technology will make it easier for doctors to detect changes early and practice preventative medicine.
