Efficacy of the curves training program for loosing body weight, body circumferences and fat mass percentage: a non randomized clinical trial

Purpose. Hypokinesia is the fourth cause of endemic death in the world. The prevalence of obesity, caused by hypokinesia, in the world continues to increase and it is the main risk factor of chronic diseases. Our aim was to evaluate the effectiveness of curves program and High-Intensity Interval Training (HIIT) in healthy women. Methods. The study design is a non-randomized clinical trial. Eighty women with age between 30 to 40 years (who train 3/4 times a week) participated over a period of six months. They were allocated into a "Curves" program group (n = 40) and a "High-Intensity Interval Training" group (n = 40). BMI, body fat, the fat mass percentage was calculated by OMRON body fat 306 TM at baseline and the end of the intervention. Results. the results between high-intensity interval training and curves show that curves scores were significantly lower among Interval training. after 6 months the most impact was on "Abdomen loss "in Curves Group Mean(SD) = -4.48(1.70). According to the multivariate analysis, we can say that for all the dependent variables Weight loss -0.320 (< 0.001), Trunk loss -0.376 (< 0.001), Abdomen loss -0.276 (< 0.001), Hip loss -0.302 (< 0.001), Lower arm loss -0.248 (0.003) and Fat mass loss -0.153 (0.061) the curves group shows significant results in comparison with the high-intensity interval training group (p < 0.001) while the civil status is significantly associated with only "Upper arm loss" variable (beta = -0.357; p < 0.001). Conclusions. This "Curves" program improved strength muscles, loss of fat and fat mass reduction more than High Intensity Interval Training.
