Effect of High Intensity Interval Training (HIIT) and aerobic continuous training on lipid profile, physiological indicators and aerobic and anaerobic performance in sedentary male

The aim of this research was to evaluate the Effect of High Intensity Interval Training (HIIT) and aerobic continuous training on lipid profile, physiological indicators and aerobic and anaerobic performance in sedentary male. In this experimental study, 20 male sedentary male (aged 20-30 years) in a randomized and double-blind design were divided in two equal HIIT and aerobic continuous training groupS. Before and after training period, all subjects were participated in six week HIIT and aerobic continuous training. Blood samples were obtained in the two phases: 24 hours before and after training protocols. Maximum oxygen uptake (VO2max), ventilatory threshold (VT), mean power outpot (MPO), Peak Power Output (PPO), Fatigue Index, Body Composition (BC), Lipid profile, and C-reactive protein (CRP) were analyzed. Change any of the parameters (mean and standard deviation) of four stages repeated ANOVA and independent and dependent sample T tests. The significance level was set at p<0.05. Four weeks of HIIT and aerobic training cause significantly increased in VO2max, MPO and PPO (P < 0.05). There was a significant difference in the percentage of fat in the HIIT group (P < 0.05). In addition, there was a significant decrease in thr CRP, Triglycerides, cholesterol and LDL in HIIT group (P < 0.05).
