The effect of the resistance training in water on the bone mineral density (BMD) in elderly women

Reduction of bone density is some risk factors of falling, injury, or even death in elderly people. The purpose of the present study is investigating the effect of 12 weeks resistance training in water on bone density of elderly women.
Thus 24 old women were selected after medical screening and randomly divided into two groups experimental (12 people, age 65±3/46 year, height 157/586/68 cm, weight 66/6811/18 kg and BMI 27/214/08) and control (12 people, age 652/81 year, height 156/586/72 cm, weight 63/636/17 kg and BMI 25/801/83). First of bone density (neck of femur and vertebra) were measured. To measure bone density DEXA way was used. Then subjects of experimental group got a resistance training program in water (12 weeks , 2 sessions in a week , every session 1 hour) .The control group got no intervention. Bone density was modulated again after 12 weeks resistance training in water. For intra group comparison of data correlated t test was used and for comparison between groups independent t test was used.
Results showed after 12 weeks resistance training in water in experimental group no significant changes were seen in bone density in neck of femur and vertebra (p The results of this study appear to be 12 weeks of resistance training in the water to maintain bone density and an increase in BMD of the practice of older women for recommended.
