By Kate A Ward, et al. • www.ProHealth.com • February 4, 2009


Context: There has been a resurgence of vitamin D deficiency among infants, toddlers and adolescents in the United Kingdom. Myopathy is an important clinical symptom of vitamin D deficiency, yet it has not been widely studied.

Objective: To investigate the relationship of baseline serum 25-hydroxyvitamin D concentration (25(OH)D) and parathyroid hormone (PTH) with muscle power and force

Design: Cross sectional study

Setting: Community based in a secondary school

Participants: Ninety-nine post-menarchal 12–14 year old females

Main outcome measures: Jumping mechanography to measure muscle power, velocity, jump height and Esslinger Fitness Index (EFI) from a two legged counter movement jump and force from multiple one-legged hops. Body height, weight and serum concentrations of 25(OH)D, PTH and calcium (Ca) were measured.

Results:

Median serum 25(OH)D concentration was 21.3 nmol/L, range 2.5 – 88.5 nmol/L and PTH 3.7 pmol/L (range 0.47 – 26.2 pmol/L).

After correction for weight using a quadratic function there was a positive relationship between 25(OH)D and jump velocity (p=0.002), jump height (p = 0.005), power (p = 0.003), Esslinger Fitness Index (p=0.003) and force (p = 0.05).

There was a negative effect of PTH upon jump velocity (p = 0.04).

Conclusions: From these data we conclude that vitamin D was significantly associated with muscle power and force in adolescent girls.
