Vitamin D linked to better muscle power

February 5, 2009

Teenage girls with higher vitamin D levels may be able to jump higher and faster than their peers with lower levels, British researchers found.

Lead author Kate Ward of the University of Manchester said that not only does vitamin D work with calcium to keep bones strong, but researchers now believe teenage girls with higher levels of the vitamin may be able to jump higher and faster than girls with lower levels.

The researchers collected vitamin D levels for 99 girls, ages 12-14. To test the girls’ muscle function, the girls were instructed to jump as high as possible while researchers used a device designed to measure power and performance called jumping mechanography.

The study, published in the the Journal of Clinical Endocrinology and Metabolism, found that after controlling for differences in the girls’ body weight, the girls with the highest vitamin D levels had the highest jump speeds, jump height, power and force.

The study is published in the Journal of Clinical Endocrinology and Metabolism.
