The purpose of this research was to investigate the effect of 8 and 12 weeks of high intensity interval training (HIIT) on the serum level of C-reactive protein (CRP), interleukin-6 (IL-6), homocysteine (HCY) and lipid profile of active middle-aged men.For this purpose, 30 active middle-aged men, were randomly divided into two groups: HIIT training and control group. HIIT Training subjects do HIT training 3 session per week for 12 weeks with 90% of maximum heart rate. The Serum levels of CRP, IL-6, HCY, HDL, LDL, TC and TG were measured 12 hours before the first session of training protocol, and 48 hours after 8th and 12th weeks of HIIT. Results show that HIIT had a significant effect on LDL, TC and TG Indices in active middle-aged men in both 8 and 12 weeks (P˂0/05). On the other hand, HIIT did not have a significant effect on CRP (P=0/848), IL-6 (P=0/080) and HCY (P=0/247) indices in 8 weeks, but it did have a significant effect on CRP (P=0/003), IL-6 (P=0/019) and HCY (P=0/012) indices in 12 weeks. HIIT appears to produce favorable changes on lipid profile of middle-aged men over a period of 8 weeks, But it does not have the ability to improve their inflammatory indicators and create favorable changes in inflammatory indices, it is necessary to perform HIIT for more than 8 weeks and a period of 12 weeks will bring about favorable changes and It is likely to have an effective role in preventing middle-aged heart diseases.

Introduction: The aim of this study was to investigate the effect of eight weeks of high intensity interval training (HIIT) and Portulaca Oleracea extract on Angiopoietin-like 4 Protein (ANGPTL4) level and insulin resistance in rats with NAFLD. Methods: Twenty five male Wistar rats were randomly divided into five groups: healthy control, fatty liver control, HIIT, Portulaca Oleracea extract, and HIIT+Portulaca Oleracea extract. To induce NAFLD, the rats were fed a high-fat diet for 12 weeks. Portulaca Oleracea supplement at 400 mg/kg was given to the experimental groups. HIIT was performed for 8 weeks, 5 sessions per week at 90% maximum speed. Hepatic ANGPTL4 level and insulin resistance were measured after 8 weeks of HIIT and consumption of purslane extract. One way anova and tukey post hoc test was used for data analysis.Results: Insulin resistance was significantly higher in fatty liver control group than healthy controls (P=0.002). But it was significantly lower in HIIT group (P=0.01), Portulaca Oleracea extract (P=0.037), and HIIT+Portulaca Oleracea extract group (P=0.012) than that in fatty liver control group. ANGPTL4 levels in the healthy control group was significantly higher than fatty liver control group (p=0.01). levels of this index in HIIT group (p=0.036), Portulaca Oleracea extract (p=0.01) and HIIT+ Portulaca Oleracea extract (p=0.007) was significantly lower than the fatty liver control group. Conclusion: It seems that HIIT and Portulaca Oleracea extract can play an important role in controlling the progression of this disease by reducing the level of ANGPTL4 and insulin resistance in patients with NAFLD.
