ABSTRACT
Aims
Osteoporosis is considered as a widespread problem for women, which causes bone fractures after simple trauma. In long term, exercise can reduce the risk of osteoporosis. This study aimed to investigate the effect of walking program on bone mass density in prevention of bone loss and osteoporosis in obese and thin girls.
Materials & Methods 40 non-athlete obese and thin girls of Gilan University who were volunteered to participate in the study were randomly divided into four experimental and control groups. The measurements of bone mass density or BMD (hip and spine), body composition (weight, fat mass percentage, fat free mass) and blood variables (phosphorus, calcium, serum estrogen) were done before and after the intervention. Experimental groups performed an exercise program that included 30 minutes walking with heart rate intensity of 50 to75 %, 3 sessions per week for two months. The data were analyzed by one-way ANOVA.
Results bone mass density in both experimental groups slightly increased after two months. But this increase was not significant (p>0.05). Also no significant change was observed in blood factors of young girls comparing to basic value (p>0.05). But, walking program had significant effect on all components of body composition in obese and thin girls (p<0.05).
Conclusion long term and intensive walking program has positive effects on BMD and its effective factors in young girls.
