         This research aimed to study the effects of a training program with a fit ball on body mass index, waist-hip ratio, muscle mass and percent body fat in obese women. The participants were 15 female volunteers aged 45-60 years with BMI of 30.0-39.9 kg/m². The duration was 16 weeks. The data were collected 3 times: before the experiment, after 8 weeks of the experiment and after 16 weeks of the experiment. For the body composition, weight, height, body mass index (BMI), waist-hip ratio (WHR), muscle mass and fat percentage. The data were analyzed by One-Way ANOVA with Repeated Measures.

          The research results showed that the mean scores of body mass index (BMI) and fat percentage test before training, after 8 weeks and after 16 weeks were statistically significantly different at the .05 level. Those after 8 weeks, after 16 weeks were not statistically significantly different at the .05 level. The mean scores of waist-hip ratio (WHR) did not statistically significantly differ at the .05 level.

          The mean scores of the muscle mass test before training, after 8 weeks and after 16 weeks were statistically significantly different at the .05 level. Those after 8 weeks and after 16 weeks were statistically significant different at the .05 level.
