Comparison the Effect of Eight Weeks High Intensity Interval Training (HIT) and Morning Exercises on Lipid Profile of North Khorasan Police Force

The aim of this study was compare the effect of eight weeks high intensity interval training (HIT) and morning training on lipid profile of Police force personnel. Methods For this purpose, 50 employees of Bojnourd Police force, randomly divided into two groups: 1. HIT training and 2. Morning training. HIIT Training subjects do HIT training 3 times per week for 8 weeks with 90% of maximum heart rate. Lipids profile levels, 12 hours before the first session and 48 hours after the last session, were measured. For data analysis from paired t test and Wilcoxon for within group change and independent t test and U-mann whitney for between group change in significant level of P<0.05, were used. results show that 8 weeks of HIT training an significantly reduces LDL, TG and TC level (P<0.05). Eight weeks of morning training had no significant effect on any of the research indicators. Between 8 weeks of HIT training and morning training in LDL, TC, TG, levels in polis force personnel, significant difference was observed. this results show that HIT training have positive effect on lipids profile of police force personnel; so it can be reduce classical cardiovascular risk factor in polis force personnel, HIT training be added to morning training.
