Abstract
Aim: Angiopoietin-4 (ANGPTL4) is the inhibitor protein of lipoprotein lipase playing role in regulating lipids metabolism, glucose hemostasis and insulin sensitivity. The purpose of this study was to investigate the effect of four weeks of high intensity interval training (HIIT) versus aerobic training on serum levels of angiopoietin-4 (ANGPTL4) and lipids profile in elite handball player girls. Methods: 30 young handball player girls (mean aged 16.85±1.4 years), with at least four years of membership history in handball team of North Khorasan Province, 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 48 hours after last training session to assess blood factors. Data analysis was done by One-way ANOVA, paired t-test, and Pearson correlation, and p < 0.05 considered significant. Results: There were no significant differences between ANGPTL4 levels following HIIT and aerobic training (P>0.05). 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. Conclusion: It seems that volume and intensity of exercise training do not effect on serum levels of ANGPTL4 in elite handball player girls.
