Filter by:This study examined the effects of 8 months of Yoga training on bone density and bone turnover markers in premenopausal women, ages 35-50 years. The style of Yoga used was power Yoga that involved postures with a jumping component. The investigators hypothesized that the Yoga intervention would result in beneficial improvements in bone turnover markers, by increasing the bone formation marker and decreasing the bone resorption marker.
The effects of two vitamin K-forms on carboxylation of the vitamin K-dependent proteins osteocalcin and matrix-gla protein will be compared after supplementing these vitamins in a nutritional dose range. The investigators hypothesized that MK-7 is more effective than K1 at a dose comparable to the RDA of vitamin K.
The primary objective of this randomized, double-blind, placebo-controlled trial is to determine the effect of vitamin D and calcium supplementation (800IU and 2000mg, respectively) on biochemical indicators of nutritional status and bone health in military personnel during Army basic combat training (BCT) and Air Force basic military training (BMT). The investigators hypothesize that daily supplementation with vitamin D and calcium during military training will improve vitamin D status, stabilize PTH levels, and result in improvements in markers of bone health. As a result of the investigators study design, the findings will provide critically important data regarding the concentration of vitamin D in blood necessary to stabilize PTH levels and to optimize bone formation during initial military training.
To assess the impact of a 12 month vitamin K supplementation intervention on bone health in adult Crohn's disease patients
To determine if increasing the amount of calcium that girls eat or the degree of exercise in which they participate will increase their bone strength.
The aim of this experimental study was to test the effect of increasing dietary calcium intake to 1500 mg/day on increases in bone quality in adolescent females. The hypothesis to be tested is: adolescent females who consume a high calcium diet will have a greater increase in bone quality, as measured by densitometry and ultrasound, than adolescent females who consume their usual dietary calcium intake.
