Vitamin D
is an essential element in athletic performance. Not only vital to bone
development, Vitamin D allows body cells to utilise calcium, muscle fibre
development and growth and optimum immune system function.

Vitamin D Sports Performance |
Vitamin D
is absorbed through exposure to sunlight, though with many people working long
hours indoors, it is common to find that we’re deficient. Dietary sources don’t
provide an adequate amount in most cases (unless you’re guzzling litres of
fortified milk or taking a dose of cod-liver oil each day!).
Researchers
recently tested the jumping ability of a group of adolescent athletes. The
results found that those with the lowest levels of Vitamin D tended not to jump
as high, leading to the conclusion that low levels of D lead to impaired muscle
power. It is also thought to lead to greater risk of injuries and longer
recovery periods.
In a
Creighton University study, female athletes given Vitamin D supplements
recovered from stress fractures at double the rate of those not given the
supplement.
Five to
thirty minutes of sunlight per week is safe and sufficient in most cases. It
cannot be absorbed through sunscreen so ensure that post-sunlight exposure
(maximum 30 minutes) you are applying UV protection for safety!

Or try
supplements. 1,000 IU a day and much more for people who are deficient is
probably close to ideal. This, by the way, is about double the current
recommended daily allowance. Most experts anticipate that this allowance will
be revised upward soon. Consult with your doctor before beginning supplements.
Overdoses of Vitamin D are rare, but can occur.
