Effect of High Intensity Interval Training Versus Aerobic Training on Serum Levels of Angiopoietin-Like 4 and Lipids Profile in Elite Handball player Girls

The purpose of this study was to investigate the effect of four weeks of high intensity interval training (HIIT) versus aerobic training (high volume- moderate intensity) on serum levels of angiopoietin-4 (ANGPTL4) and lipids profile in elite handball player girls. For this purpose, 30 young handball player girls were selected and randomly divided into two groups of experimental and one control group. Subjects in experimental groups participated in four weeks of HIIT [running at intensity of 95-90 percentage of maximum heart rate and resting intervals of 1-3 minutes running at 60-50 percentage of maximum heart rate] and aerobic training (running at 50-70 percentage of maximum heart rate, 45-60 minutes per session), three sessions per week. The blood samples were taken factors before and after training protocol to assess blood factors. Data analysis was done by One-way ANOVA, paired t-test, and Pearson correlation, and P0.05). However, triglyceride levels significantly decreased in aerobic group (P=0.032) and cholesterol levels significantly declined in HIIT group (P=0.048). Furthermore, there existed significant correlation between changes in ANGPTL4 levels and changes in levels of triglyceride (P=0.010) and high-density lipoprotein (P=0.014), following HIIT and aerobic training, respectively. It seems that volume and intensity of exercise training do not effect on serum levels of ANGPTL4 in elite handball player girls.
