Power training is more effective than strength training for maintaining bone mineral density in postmenopausal women.
Physical exercise has a favorable impact on bones , but optimum training strategies are still under discussion . In this study , we compared the effect of slow and fast resistance exercises on various osteodensitometric parameters .  Fifty-three postmenopausal women were r and omly assigned to a strength training ( ST ) or a power training group ( PT ) . Both groups carried out a progressive resistance training , a gymnastics session , and a home training over a period of 12 mo . During the resistance training , the ST group used slow and the PT group fast movements ; otherwise there were no training differences . All subjects were supplemented with Ca and vitamin D. At baseline and after 12 mo , bone mineral density ( BMD ) was measured at the lumbar spine , proximal femur , and distal forearm by dual-energy X-ray absorptiometry . We also measured anthropometric data and maximum static strength . Frequency and grade of pain were assessed by question naire . After 12 mo , significant between-group differences were observed for BMD at the lumbar spine ( P < 0.05 ) and the total hip ( P < 0.05 ) . Whereas the PT group maintained BMD at the spine ( + 0.7 + /- 2.1 % , not significant ) and the total hip ( 0.0 + /- 1.7 % , not significant ) , the ST group lost significantly at both sites ( spine : -0.9 + /- 1.9 % ; P < 0.05 ; total hip : -1.2 + /- 1.5 % ; P < 0.01 ) . No significant between-group differences were observed for anthropometric data , maximum strength , BMD of the forearm , or frequency and grade of pain . These findings suggest that power training is more effective than strength training in reducing bone loss in postmenopausal women
