摘要：Objective: The purpose of this study, determine effect of six weeks high intensity interval training onhomocysteine and Lipid Profile levels in sedentary young men. Methods: Eighteen inactive young menvoluntarily participated in this study 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 high intensity intervaltraining sessions per week for 6 weeks. Each session consisted of either four to six repeats of maximal sprintrunning within a 20 m area with 20–30 s recovery. Fasting blood samples were collected 24 hours before and48 hours after exercise protocol. Data were analyzed by dependent t test. Results: Results showed that,although homocysteine levels in the experimental group reduced 18% compared with control group, but thischange was not statistically significant (P>0.05). Although serum concentrations of triglycerides, low-densitylipoprotein, total cholesterol and the ratio of total cholesterol to high-density lipoprotein decreased and highdensitylipoprotein levels increased, but these changes were not statistically significant (P>0.05).Conclusions: According to the results of this study, high intensity interval training seems to be a timedependentstrategy with a relative improvement in homocysteine and Lipid Profile levels, could lead to theprevention of cardiovascular disease in sedentary individuals.
