Overview Sports and vitamin D

Athletes are helped by vitamin D by:

Faster reaction time
Far fewer colds/flus during the winter
Less sore/tired after a workout
Fewer micro-cracks and broken bones
Bones which do break heal much more quickly
Increased VO2 and exercise endurance Feb 2011
Indoor athletes especially need vitamin D
Professional indoor athletes are starting to take vitamin D and/or use UV beds
Olympic athletes have used UV/vitamin D since the 1930's
The biggest gain from the use of vitamin D is by those who exercise less than 2 hours per day.
Reduced muscle fatigue with 10,000 IU vitamin D daily
Muscle strength improved when vitamin D added: 3 Meta-analysis
Reduced Concussions

Wikipedia item mentions how the study of UV on sports resulted in creating Tanning Parlors

While studying the beneficial effects of ultraviolet light on athletes, German scientist Friedrich Wolff noticed an interesting side effect - tanned skin.
Realizing the appeal of a beautiful tan, Wolff founded the indoor tanning industry.
His research led to development of indoor tanning equipment and lamp technology.

Happened to notice many professional black athletes had shaven heads or very short hair

Most likely that they have short hair due to being easier to move around quickly on the basketball court

However, if that were the only reason, the white players would also have very short hair, and they do not seem to.

Tendonitis and vitamin D on the web

TeondonitisExpert clips
- The research overwhelmingly shows that Vitamin D deficiency is the cause of an incredible amount of pain, disease, and physical dysfunction that we just consider to be normal these days.
- One of the many possible symptoms of Vit D deficiency is random pain in the body. This can look exactly like Tendonitis...unless you know what you're looking for.

- Within the first 2 weeks the pain and tendonitis was gone from my shoulders
