Comparing the Effect of 8 Weeks Iso-distance Interval and Continuous Exercise Training on Appetite Control and Body Composition in Sedentary, Overweight and Obese Girls

The aim of this study was to compare the effects of two methods of Iso-distance continuous and intermittent exercise training on appetite and body composition in overweight and obese sedentary girls. Twenty six overweight and obese girls who were resident of Shahed university dormitory were purposefully selected and randomly assigned into following Iso-distance groups: interval exercise training and continuous exercise training. Each Group performed their own protocol for 8 weeks, 3 times per week with specified intensity and distance. Before starting the protocol and 24 hours after the last training session, appetite, percentage of body fat, waist circumference, waist-to-hip ratio, body mass index, and maximum oxygen uptake were measured at same condition. Data were analyzed using Paired sample t test and analysis of covariance. The findings showed that neither interval and nor continuous exercise training protocol had a significant effect on appetite (p>0.05). Also, two exercise training protocol significantly reduced percentage of body fat (p=0.377), body mass index (p=0.372), waist-to-hip ratio (p=0.509) and waist circumference (p=0.242), but the difference between groups was not significant (p>0.05). It seems that eight weeks of continuous and interval exercise training had no stimulatory or suppressive effect on appetite. Also, when the protocols are Iso-distance interval and continuous exercising training had similar effect on body composition of overweight and obese sedentary girls.
