The aim of this study was to determine the effects of resistance training and detraining on muscle mass in Tehranian women. Twenty post-menopausal women aged over 50 years old were enrolled. After matched for weight, they were randomly assigned into control and resistance training group. The experimental designed program consisted of 12 weeks of resistance training and four weeks of detraining. Resistance training program was performed three times a week (non-consecutive session), three sets of 10 repetitions for 10 movements at least for 60 min. The exercise testing equipment used in this investigation was Thera-Band tubing. The resistance exercise program was designed for each participant, based on 80%, 85%, and 100% 10-repetition maximum. Control group received no intervention. Skin fold thickness was determined by caliper at baseline and 12 and 16 weeks after the intervention. Percentage of body fat was estimated from skin fold thickness (triceps and subscuplar) by McArdle method. Fat mass and fat free mass were calculated. Range of motion for trunk flexion and extension was determined.
