High intensity interval training (HIIT) is a kind of exercise training that suggested for individuals with any sufficient time for regular training. The purpose of this study was to determine the effects of 8 weeks of HIIT on body composition and some indexes of relative to metabolic diseases in young men with overweight.For this aim thirty young men participants (age: 21.14±4.0, height: 176.1±6.4 and weight: 84.86±7.3) were randomly assigned to HIIT and control groups (n=15). HIIT groups exercised three times per week, 10-20 min per session for 8 weeks and control group. Baseline and after 8 weeks intervention blood samples and body composition analyze were assessed.Results from independent t test showed that insulin sensitivity and total triglyceride in HIIT group increased (p≤0.05). No changes in variables include total plasma cholesterol, cholesterol), LDL-C (low density lipoprotein-cholesterol), HDL-C (high density lipoprotein-cholesterol), fat percentage and body mass index occurred.These findings suggested that HIIT with low volume and time in comparison of traditional continues training, probably by activation of signal pathway in muscle cells, promoted insulin sensitivity of muscle cells, but cost of energy in HIIT, is not be enough for change in body composition.
