SAN DIEGO, CA Vitamin D deficiency has been known to cause an assortment of health problems, a recent study being presented at the American Orthopaedic Society for Sports Medicine's (AOSSM) Annual Meeting in San Diego today, suggests that lack of the vitamin might also increase the chance of muscle injuries in athletes, specifically NFL football players.
"Eighty percent of the football team we studied had vitamin D insufficiency. African American players and players who suffered muscle injuries had significantly lower levels," said Michael Shindle, MD, lead researcher and member of Summit Medical Group.
Researchers identified 89 football players from a single NFL team and provided laboratory testing of vitamin D levels in the spring 2010 as part of routine pre-season evaluations. The mean age of the players was 25. The team provided data to determine the number of players who had lost time due to muscle injuries. Vitamin D levels were then classified based on player race and time lost due to muscle injury.
Twenty-seven players had deficient levels (< 20 ng/ML) and an additional 45 had levels consistent with insufficiency (20-31.9 ng/mL). Seventeen players had values within normal limits (>32 ng/mL). The mean vitamin D level in white players was 30.3 ng/mL while the mean level for black players was 20.4 ng/mL. Sixteen players suffered a muscle injury with a mean vitamin D level of 19.9.
"Screening and treatment of vitamin D insufficiency in professional athletes may be a simple way to help prevent injuries," said Dr. Scott Rodeo, MD, Co-Chief of the Sports Medicine and Shoulder Service at the Hospital for Special Surgery. "Further research also needs to be conducted in order to determine if increasing vitamin D leads to improved maximum muscle function," said Dr. Joseph Lane, MD, Director of the Metabolic Bone Disease Service at the Hospital for Special Surgery."
The American Orthopaedic Society for Sports Medicine (AOSSM) is a world leader in sports medicine education, research, communication and fellowship, and includes national and international orthopaedic sports medicine leaders. The Society works closely with many other sports medicine specialists, including athletic trainers, physical therapists, family physicians, and others to improve the identification, prevention, treatment, and rehabilitation of sports injuries. AOSSM is also a founding partner of the STOP Sports Injuries campaign to prevent overuse and traumatic injuries in kids.

did playing in a dome stadium have anything to do with individual players’ levels?
all from same team...maybe I should read before posting...
Sounds like they need to get a tan.
One reason might be, if they are injured they aren’t spending so much time outside in the sun. Also my doc told me if you have any kind of autoimmune diseases(inflammation too maybe?) your body will soak up vitamin D, you end up needing more. The darker your skin is, either from genetics of tanning/burning, or if you are over weight it takes longer for your body to make D from the sun.
Also while there on my vacation, I shared that story with another friend of mine in MN and she happened to be due for a yearly physical. She specifically asked her doctor to test her Vitamin D level. He did. She was soooo low! He gave her high dosage Vitamin D pills and she said, "I felt better and I SLEPT LIKE A BABY!!!" She was sold!
I don't know...just sayin...
That when watching football games, most players suffering leg cramps seem to be blacks points to slight physiological differences.
This is rhetorical overkill. There's a know correlation, but nobody has shown causation, or even suggested a mechanism for low Vitamin D to cause trouble. On the other hand, there are peer-reviewed papers on low Vitamin D being caused by the disease process, and a discussion of the mechanism.
"Deficiency in vitamin D has been widely regarded as contributing to autoimmune disease, but a review appearing in Autoimmunity Reviews explains that low levels of vitamin D in patients with autoimmune disease may be a result rather than a cause of disease and that supplementing with vitamin D may actually exacerbate autoimmune disease."
You’re probably thinking about the old Astroturf—it was hard on knees IIRC.
You need to refrain from posting so enthusiastically when you really don’t have a clue.
In a mouse model of multiple sclerosis, vitamin D was found to reverse experimental autoimmune encephalitis by inhibiting the synthesis of chemokines (22). Similar effects were found by two different groups using a mouse model for diabetes. Nonobese diabetic mice treated with vitamin D were found to have a decrease in pancreatic islet chemokine expression, which was accompanied by less insulitis and inhibition of type 1 diabetes development (23, 24)
On May 6, enroute to the Bahamas I slipped at the airport, hurt my arm and bloodied my upper lip. Assured by EMS I had nothing broken, I hopped on the plane and went.
On May 9, somehow I got into a wetsuit and swam with dolphins.
May 12, back home went to dr. who confirmed I had fractured my shoulder..and messed up my rotator cuff.
I am doing PT now to improve range of motion but I haven's had any real pain or problems. Never lost sleep. Took 2 Aleve or Advil 3X dailey for pain first 2 weeks.
I have given credit to the Vit D3 for how well I've done.
I am female, 72 years old!...and never played in the NFL. LOL!
One of the first studies was in a hospital for the criminally insane. I wasn't there either!
I am a firm believer in Vit D3.
What is the difference between D and D3?
Thanks to FR I started reading about vitamin D3
I am also a firm believer, since started taking 5000 mg of D3 daily I have not been sick once in over 18 months. Not even a sniffle.
I don’t like to take medicine. It seems people have more problems with their meds than before they started taking them!
