Institute of Health Professions, 101Merrimac Street, Room 1059B, Kelley GA, Kelley KS, Tran ZV: Resistance training and bone mineral density in women: a meta-analysis of controlled trials. Am J Phys MedRehabil 2001;80:65–77.
The purpose of this study was to use meta-analysis to examine the effects of resistance training on bone mineral density at the femur, Department of Defense, Army MedicalResearch and Material Command lumbar spine, and radius in pre- and postmenopausal women. Resis- tance training had a positive effect on bone mineral density at thelumbar spine of all women and at the femur and radius sites for post- menopausal women. It was concluded that resistance training has a American Journal of PhysicalMedicine & Rehabilitation positive effect on bone mineral density in women.

Osteopenia and osteoporosis are major public health problems in the
United States, affecting primarily lean, white, postmenopausal women.1 Cur-rently approximately 26.2 million white, postmenopausal women in the UnitedStates have either osteopenia or osteoporosis.1 More specifically, osteopenia,defined as bone density that is 1 to 2.5 SD below the young adult referencerange, affects an estimated 16.8 million (54%) of postmenopausal white wo-men in the United States, whereas osteoporosis, defined as bone density Ͼ2.5SD below the young adult reference range, affects another 9.4 million(30%) women.1, 2 Low-bone density increases the risk for fractures, particularly atthe hip, spine, and distal forearm. Currently, the estimated lifetime risk forfracture in 50-yr-old white women in the United States is 17.5% at the hip,15.6% at the vertebrae, and 16.0% at the distal forearm.1 In terms of themortality rate, the survival rate at 5-yr follow-up relative to those of like ageand gender is 0.83 for those who have experienced a hip fracture, 0.82 forvertebral fractures, and 1.00 for fractures of the forearm.3 In the United States, Resistance Training and Bone Mineral Density crease substantially in future years.
