OBJECTIVES: To evaluate the effects of an exercise program on handgrip strength (HS) in elderly women with low bone mass. SUBJECTS AND METHODS: Thirty-six elderly women were randomized to the intervention group -- GI (n = 18) and control group -- GC (n = 18). Participants were evaluated by means of a HS test, using a handgrip dynamometer. GI performed strength, balance and functional mobility exercises, and GC performed stretching exercises. Both groups had sessions twice a week for 50 minutes, during 4 months. RESULTS: GI had a significant increase in handgrip strength equal to 31.38%. No differences were observed in GC. There were correlations between HS test and bone mineral density (BMD) of the femoral neck (r = 0.582, p = 0.003) and total femur (r = 0.485, p = 0.01). CONCLUSION: Results indicate a propensity to increase elderly HS, and showed significant correlations between HS and BMD.
