The BEST (Bone, Estrogen, Strength Training) was one of the largest funded National Institutes of Health research projects to study the effect of strength training on preventing osteoporosis and sarcopenia in post-menopausal women. Osteoporosis is often called the silent disease that goes unnoticed until one is diagnosed with low bone and has a significant fracture risk. After age 40, adults lose a quarter to a third of a pound of muscle a year and gain that much body fat. Loss of muscle mass plays a role in the gradual accumulation of excess body fat and leads to loss of strength, which ultimately means premature disability and loss of independence. This presentation will share the program results detailing progress in exercise adherence, as well as the psychological, social and wellness based concepts that created this sustained exercise effort.
