A new study found supplementation with Calcium could prevent exercise associated reductions in bone density in post menopausal women.
33 women between the age of 57 and 65 participated in this double-blind, randomized, cross over study. The first group of 10 women, drank a sports drink with 1000 mg of calcium added one hour before exercise or a placebo. The second group was made up of 23 whom drank a sports drinks with either 1000 mg of calcium or a placebo 15 minutes before exercise. Both groups also continued drinking their sports drink during their one hour of brisk walking.
The results showed the calcium supplementation stopped calcium decreases previously seen in athletes. Additionally the increased parathyroid hormone (PTH) levels seen in athletes were reduced and bone reabsorption (CTX) increased in the group supplementing an hour before exercise. The second group who drank their sports drinks 15 minutes before exercise saw less calcium decreases than the placebo groups but their calcium losses were not totally stopped like those seen in the first group. Levels of PTH and CTX were not affected in the second group.
