Seven-month wintertime supplementation of 1200 IU vitamin D has no effect on hand grip strength in young, physically active males: A randomized, controlled study.

ABSTRACT:

Background

There has been a growing interest in the role of vitamin D for the well-being and physical performance of humans under heavy training such as conscripts in military service; however, there is a lack of long-term supplementation studies performed on members of this type of young, physically active, male population. The hypothesis of the study was that vitamin D supplementation during wintertime will decrease the prevalence of critically low vitamin D blood serum levels and increase hand grip strength during the winter season among young male conscripts.

Study design

Longitudinal, triple-blinded, randomized, placebo-controlled trial.

Methods

Fifty-three male conscripts from the Estonian Army were randomized into two groups: 27 to an intervention group and 26
