The Effect of 12 Weeks of High-Intensity Interval Training (HIIT) on Homocysteine and CRP Cardiovascular Risk Factors and Body Composition in Overweight Men

Background & Objective: High levels of homocysteine inflammatory markers and C-Reactive Protein (CRP) cause many complications, including atherosclerosis, venous thrombosis, and cardiovascular problems. The objective of the present study was to investigate the effect of 12-weekHigh Intensity Interval Training (HIIT) on homocysteine, CRP, and body composition in overweight men. Materials & Methods: In this quasi-experimental study, 20 students of Kashan University of Medical Sciences with a body mass index between 25 and 30 kg/m2, were purposefully selected and were randomly divided into experimental and control groups. The experimental group had practiced in the HIIT program with the intensity of up to 90 percent of maximum heart rate for 12 weeks. Before and after exercise, the amount of homocysteine, CRP, weight, body fat percentage, body mass index, and waist-to-hip ratio were calculated. The data were analyzed by using dependent and independent t-test at a significance level of P<0.05. Results: The results showed that12 weeks of HIIT had significant effects on reducing serum levels of homocysteine and HSCRP, body weight, body fat percentage, BMI, and WHR in the experimental group compared to the control group (P
