Effects of High-Intensity Interval and Mini-Trampoline Training with Calorie Restriction on Body Composition and Aerobic Capacity in Overweight and Obese women

Introduction: Weight gain and obesity are one of the most important health issues and one of the most severe public health problems. This study aimed to determine the effect of 10 weeks of High-Intensity Interval training (HIIT) and Mini-Trampoline training (MTT) with calorie restriction (CR) on body composition and aerobic capacity in overweight and obese women. Materials and Methods: Forty-eight overweight and obese women with a mean (age: 32.71±4.11 yrs, weight: 75.19±4.86 kg) participated in the present study based on the inclusion criteria and voluntarily. Subjects were randomly divided into four equal groups (12 subjects): Experimental group 1: MTT with CT, Experimental group 2: HIIT with CR, Experimental group 3: CR, and Control group: No restriction calories were divided. Body mass index (BMI), waist-to-hip ratio (WHR), waist-to-height ratio (WHTR), skeletal muscle mass (SMM), and body fat percent (PBF) were analyzed using the Boca Model X1 body composition analyzer, and for aerobic capacity, the Cooper test was used. CR (deduction of 500 calories from the daily energy intake of individuals) was for 10 weeks. HIIT and MTT have performed three sessions per week and each session was one hour of high-intensity exercise. The control group was asked to continue their daily activities and maintain a normal diet. Results: A 10-week period of MTT with CR improved BMI (P=0.001), WHR (P=0.004), BF and PBF (P<0.001), but HIIT had no effect on body composition (P<0.05). CR diet had a positive effect on BMI (P=0.001), WHR (P=0.009), BF (P=0.044). HIIT with CR (P<0.001) and MTT with CR (P<0.001) improved aerobic capacity and among these, HIIT had a greater effect on aerobic capacity (P<0.001). Conclusion: The results showed that MTT with CR improves the body composition in overweight and obese women. Also, the effect of HIIT on increasing aerobic capacity was greater.
