Official title:
The Effects of Vitamin D Supplementation on VO2max in Athletes: a Randomised, Double-blind, Placebo-controlled Trial
The primary aim of the study is to identify if vitamin D3 supplementation influences VO2max
in athletes.
Secondary aims are to determine if vitamin D3 supplementation impacts on measures of muscle
function, lung function, body composition, immune function and the self-reported incidence
of upper respiratory tract infection.
This double-blind, randomised, placebo-controlled trial is of parallel design and will aim
to recruit a total of 50 athletes randomised into either a placebo or treatment group for a
