摘要：The purpose of this study, determine effect of six weeks high intensity interval training (HIIT) on in Levels ofLeptin and Lipid Profile in sedentary young men. Eighteen inactive young men voluntarily participated in thisstudy and randomly divided into two groups: Experimental (n: 9, age: 24.33±1.41, height: 176.22±4.91,weight: 72.27±6.59) and Control (n: 9, age: 23.27±2.01, height: 180.22±6.88, weight: 76.27±7.33)groups. Experimental group performed three HIIT sessions per week for 6 weeks. Each session consisted ofeither four to six repeats of maximal sprint running within a 20 m area with 20–30 s recovery. Fasting bloodsamples were collected 24 hours before and 48 hours after exercise protocol. Data were analyzed bydependent t test and results showed that, following of six weeks HIIT, levels of leptin was significantlyreduced in the experimental group compared to control group (P<0.05). Although serum concentrations oftriglycerides, low-density lipoprotein, total cholesterol and the ratio of total cholesterol to high-densitylipoprotein decreased and high-density lipoprotein levels increased, but these changes were not statisticallysignificant (P>0.05). However, present study showed significantly decreased of body fat percent inexperimental group compared with control group (P<0.05). According to the results of this study, HIIT seemsto be a time-dependent strategy with a relative improvement in the lipid profile reduces body fat and leptinlevels, could lead to the prevention of obesity in sedentary individuals.
