The Bone Estrogen Strength Training (BEST) Study

The Bone Estrogen Strength Training (BEST) study was conducted between 1995 and 2001 with funding from the National Institutes of Health and Mission Pharmacal Company. The study involved an interdisciplinary team of researchers in the Departments of Physiology and Nutritional Sciences at the University of Arizona. The study results showed that weightbearing and resistance exercises over a one-year period, combined with Citracal^® calcium citrate supplementation, significantly improved bone mineral density at skeletal sites at risk for fractures in postmenopausal women.

The study was completed on 266 healthy, nonsmoking, postmenopausal women, average age 55.6 years, half of whom were currently taking hormone replacement therapy (HRT) and half of whom were not. All of the women received Citracal calcium citrate supplements that provided 800 mg a day and were instructed to take the supplements in two 400 mg doses spaced throughout the day. These women were followed for one year with their bone density measured at the hip, spine, arm, and total body, and their calcium supplement compliance was monitored regularly.

The BEST study demonstrated that a combination of adequate calcium intake and increased physical activity of a specific type prevents bone loss in both populations of women.

The key to achieving the goal of improved bone health is in the intensity of the workout and the level of resistance training performed on a regular basis. The BEST Exercise Program for Osteoporosis Prevention was developed to provide guidelines for exercise that will make a difference in bone health.
