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.

Deficiency of oestrogen at menopause decreases intestinal Ca absorption, contributing to a negative Ca balance and bone loss. Mg deficiency has also been associated with bone loss. The purpose of the present investigation was to test the hypothesis that treatment with a spray-dried mixture of chicory oligofructose and long-chain inulin (Synergy1; SYN1) would increase the absorption of both Ca and Mg and alter markers of bone turnover. Fifteen postmenopausal women (72·2 (sd6·4) years) were treated with SYN1 or placebo for 6 weeks using a double-blind, placebo-controlled, cross-over design. Fractional Ca and Mg absorption were measured using dual-tracer stable isotopes before and after treatment. Bone turnover markers were measured at baseline, 3 and 6 weeks. Fractional absorption of Ca and Mg increased following SYN1 compared with placebo (P < 0·05). Bone resorption (by urinary deoxypyridinoline cross-links) was greater than baseline at 6 weeks of active treatment (P < 0·05). Bone formation (by serum osteocalcin) showed an upward trend at 3 weeks and an increase following 6 weeks of SYN1 (P < 0·05). Closer examination revealed a variation in response, with two-thirds of the subjects showing increased absorption with SYN1.Post hocanalyses demonstrated that positive responders had significantly lower lumbar spine bone mineral density than non-responders (dual X-ray absorptiometry 0·887 ± 0·102v.1·104 ± 0·121 g/cm2;P < 0·01), and changes in bone turnover markers occurred only in responders. These results suggest that 6 weeks of SYN1 can improve mineral absorption and impact markers of bone turnover in postmenopausal women. Further research is needed to determine why a greater response was found in women with lower initial spine bone mineral density.

The aim of this study was to evaluate the effect of denosumab (Dmab) on bone mineral density (BMD) and bone turnover markers after 1 year of treatment. Additionally, the effect of Dmab in bisphosphonate-naïve patients (BP-naïve) compared to patients previously treated with bisphosphonates (BP-prior) was analyzed. This retrospective study included 425 postmenopausal women treated with Dmab for 1 year in clinical practice conditions in specialized centers from Argentina. Participants were also divided according to previous bisphosphonate treatment into BP-naïve and BP-prior. A control group of patients treated with BP not switched to Dmab matched by sex, age, and body mass index was used. Data are expressed as mean ± SEM. After 1 year of treatment with Dmab the bone formation markers total alkaline phosphatase and osteocalcin were significantly decreased (23.36% and 43.97%, resp.), as was the bone resorption marker s-CTX (69.61%). Significant increases in BMD were observed at the lumbar spine, femoral neck, and total hip without differences between BP-naïve and BP-prior. A better BMD response was found in BP-prior group compared with BP treated patients not switched to Dmab.Conclusion. Dmab treatment increased BMD and decreased bone turnover markers in the whole group, with similar response in BP-naïve and BP-prior patients. A better BMD response in BP-prior patients versus BP treated patients not switched to Dmab was observed.
