purpose of the present study was to examine the effect of a walking
exercise on body water in order to restore body water and reduction
dehydration among sedentary obese and thin women. Forty young untrained
girls between the age of 20-25 years (obese n=20, BMI>30 and
thin n=20, BMI<20) volunteered to participate in this study.
Participants were randomly assigned to two exercises (obese=10,
thin=10) and two control (obese=10, thin=10) groups matched by BMI. DXA
was used to measure each subject's body water, percentage body fat and
lean mass. Serum estrogen level by radioimmunoassay (RIA) was assessed.
Each walking session was 30 min long at an intensity corresponding to
50-75% of maximal age adjusted heart rate, 3 days per week for 2
months. Percent body fat and lean mass were affected positively by
exercise program and significant change was observed in Serum estrogen
and body water in both exercise group (p<0.05-0.001). In
conclusion this study demonstrated to 30 minutes walking exercise
improved adaptation of body fluids and to exercise training in both
obese and thin sedentary women.
