The Effect of Selected Walking Program on Bone Mass Density Body Composition and Serum Estrogen in OBESE Girls

Osteoporosis and obesity two disorders of body composition are growing in prevalence. This is while a few studies have investigated the relationship between body composition and bone mass density (BMD) with physical activity in obese girls. Thus this study aims at investigating the effect of walking programs in preventing osteoporosis and reducing obesity in obese girls. Twenty non-athlete obese girls volunteered to take part in this research. The participants then were randomly divided into two groups (Control: n=10 BMI=30.9±3.6 kg/m2 and experimental: n=10 BMI=30.2±1.8 kg/m2). The bone mass density body composition and serum estrogen of the participants were measured initially and after two months. Then the experimental group started a two-month exercise program which consisted of 30 minutes of walking with intensity of %50- %75 of heart rate three times a week. The data were analyzed through independent t-test (P
