Abstract :
The purpose of this research was to study the effect of eight weeks of moderate intensity interval training on the body composition and cardio-respiratory endurance of obese adolescent female students. Therefore, 20 obese female students voluntarily participated in this research. After obtaining consent from the parents, the subjects were randomly assigned to two equal training (n=10) and control groups (n=10). The subjects of the control group continued their normal life and the training group underwent moderate intensity interval training intervention. The training course was conducted for eight weeks with three sessions per week. The training protocol consisted of two sessions with six repetitions. In the first round, the subjects performed 6 times of 30 seconds with 70% of the maximum heart rate and had 30 seconds of active rest (running with 50% of the maximum heart rate) between the times. Before and after eight weeks, body composition was measured with a body analyzer and aerobic power through a 1600-yard test. All the analyzes were done with the covariance test and considering significance less than 0.05. The results showed that the percentage of fat and body mass index in the training group decreased significantly; on the other hand, aerobic power and lean body mass increased significantly. According to the results, it seems that intermittent training with moderate intensity is effective in improving the body composition and aerobic capacity of obese adolescent girls.
