Abstract :
The aim of the present study was to compare the effects of six weeks of high, moderate, and low-intensity aerobic training on the body composition and aerobic capacity of overweight students. This quasi-experimental study utilized a pre-test and post-test design, involving a statistical population of 30 overweight students from universities in Babol. Participants in the training groups covered the same distances over a six-week period, with three sessions each week. The distances were as follows: 2.5 km in the first week, 3 km in the second and third weeks, 3.5 km in the fourth and fifth weeks, and 4 km in the final week. The sessions were conducted at varying intensities: high, moderate, and low. The results indicated that the percentage of body fat (PBF) in the high-intensity training group showed significant changes between the pre-test and post-test. Additionally, there were notable changes in both the high and moderate intensity exercise groups at the post-test. The results showed that there was a significant difference between the effect of 6 weeks of high, moderate, and low intensity aerobic training on the body mass of overweight boys.
In the pre-test phase, there was no significant difference between the groups; but in the post-test phase, there was a significant difference between the low intensity training group and the two groups (high and moderate intensity training); so that the average body mass in the low intensity training group was significantly higher than both training groups.In contrast, the low-intensity group exhibited either minimal changes or no observable differences.
There is a significant difference in the effects of six weeks of high, moderate, and low-intensity aerobic exercise on body mass, body fat percentage, lean body mass, and aerobic capacity in overweight boys (P < 0.05). According to the results obtained, it is recommended that people who are looking for physical fitness and optimal body composition use high-intensity aerobic training. Given the great importance of energy consumption in weight loss, people with higher aerobic fitness levels are advised to train at longer distances and more days of the week to achieve greater program efficiency; that is, increase the intensity of the load.
