Abstract

The purpose of this study was to investigate the effect of low volume high-intensity interval training on markers predictive of cardiovascular disease in overweight men. Participants were overweight and obese students aged 20 to 25 years that have no regular exercise program six months before the study and only were participated in the daily activities. Thirty subjects (23.6 ± 3.03 years of age, height 174.80 ± 6.75 cm, weight 92.35 ± 9.14 kg, and BMI 31.6 kg/m2) randomized divided into control and experimental groups. The experimental group underwent 8-weeks exercise training. The exercise training program consisted of 20 min (10 intervals 1-min at 85-90% maximal heart rate that separated with 1-min at 50-55% maximal heart rate). Forty-eight before and after last sessions of exercise training anthropometrics and biochemical analysis was done. Repeted measure two-way ANOVA was used for data analysis. The results indicated that 8-weeks low volume high-intensity interval training reduced plasma levels of homocysteine, CRP, LDL and BMI (P < 0.05). Additionally, low volume high-intensity interval training increase HDL (P=0.001). It seems that low volume high-intensity interval training through reduce body weight attenuates cardiovascular risk factors in overweight men.
