Weight-bearing exercise is recommended to improve bone density. Hatha Yoga is a popular form of weight-bearing exercise that includes physical postures, stretching, breathing, and relaxation. We hypothesized that Hatha Yoga would have beneficial effects on bone turnover markers. We conducted a small feasibility pilot study with a prospective, pre-post design comparing markers of bone turnover before and after Yoga training in sedentary osteopenic postmenopausal women. Markers of bone formation were measured with serum bone-specific alkaline phosphatase (BAP). Measures of bone resorption were measured with urinary type I collagen cross-linked N-telopeptide (uNTX). Seven participants completed a 12-week series of one hour per week Yoga classes, in addition to home Yoga practice. We analyzed the correlation between time spent on Yoga and time spent on other weight-bearing exercise and change in bone turnover markers. The amount of Yoga practice was significantly correlated with BAP levels (r = 0.68, p = 0.09). A weaker, non-significant correlation was found between the amount of Yoga practice and uNTX levels (r = -.54, p = .21). Compared to Yoga, other physical activities were less correlated with BAP and uNTX levels. Yoga may have beneficial effects on bone turnover in osteopenic postmenopausal women.
