Vitamin D Deficiency Clinical Trial
Official title:
Effect of Vitamin D3 Supplementation on Exercise Performance in Wheelchair Athletes.
There is a high prevalence of vitamin D deficiency in Switzerland. In indoor-athletes as
well as wheelchair users, vitamin D deficiency occurs even more often. It is well
established that vitamin D deficiency has a negative effect on health. However, vitamin D
supplementation in individuals with a vitamin D deficiency has a positive effect on muscle
performance. In recently published studies with able-bodied subjects, it has been shown that
a normal vitamin D level (>75nmol/L) can only be achieved with a high-dose supplementation
of vitamin D.
The aim of this study is to examine the effect of vitamin D supplementation on exercise
performance in wheelchair athletes with vitamin D deficiency . All participants with a
vitamin D deficiency are assigned to the intervention group and treated with 6000 IU of
vitamin D3 daily over a period of 12 weeks. All participants who have a normal vitamin D
level will receive placebo treatment (control group). The physical performance is measured
three times at baseline, after six weeks and 12 weeks. The measurements include a Wingate
and a dynamometer test.
