Breast cancer survivors (BCS) may experience osteoporosis resulting in bone fractures. Strength/weight training exercise programs (STWE) may prevent osteoporotic fractures. The most effective intensity, duration, frequency and type of a STWE for preventing osteoporotic fractures has not been established for postmenopausal BCS. This analysis determined if STWE enhanced the effectiveness of risedronate (35mg/wk), calcium (1200 mg/day) and vitamin D (400 IU/day) in improving muscle strength, balance, and adherence to exercise in BCS at 12-months (mo) and if intensity (total weights lifted) influenced strength and balance. 217 postmenopausal BCS with a history of Stage 0, I or II breast cancer, and a DEXA T-score of </= -1.0 at any of 3 sites (hip, spine, forearm) were stratified by time since menopause (</>5 years) and randomly assigned into 2 groups [STWE (n=106) or no STWE (n=111)]. Both groups received risedronate (35 mg/wk), calcium (1200 mg/day) and vitamin D (400 IU). The SWTE groups received progressive strength/weight training exercises for upper and lower extremities and spine twice a week, for 24-mo, including at least 9-mo at home using hand and ankle weights before progressing to a fitness center. Biodex Velocity Spectrum Evaluation on the left forearm, hip and knee were conducted at baseline, 6-mo, and 12-mo to measure muscle strength. Backward Tandem Walk was used to assess dynamic balance at 3 time points. An Exercise Journal was used to determine adherence and weight loads on a weekly basis. Drug Count Logs and Adherence and Risk Factor Documentation Interview Forms were used to record adherence to medications and exercise. Data from the first 12-mo of a 24-mo intervention study, funded by NINR (1 R01 NR07743-01A1), was analyzed. There were significant differences over time between muscle strength and balance for the 2 groups at baseline and 12-mo for left knee flexion and extension, left hip flexion and extension, and left wrist flexion and extension [F (1,215) p < .001 }and balance [F (1,215), p < .001]. There were significant relationships between total weights lifted and changes in muscle strength, (p=.000) and balance (p=.033) at 12-mo. BCS participating in SWTE should be encouraged to progressively lift heavier weights over time.
