Effects of Six-Week Endurance Training in Liver Enzymes, Lipid Profile, Interleukin-6 and High-Sensitivity C-Reactive Protein (hs-CRP) Responses in People with a Family History of Coronary Artery Disease

Background: Research on the effects of moderate-intensity endurance training on inflammatory indices and cardiovascular risk factors is limited. Objectives: The aim of this study was to determine the effects of six weeks of endurance training on liver enzymes, body composi- tion, lipid profile, interleukin-6, and C-reactive protein responses in people with a family history of coronary artery disease (CAD). Methods: Thirty men (30 - 45years) participated in this study who were divided into two groups, including the control group (n = 10) and training group (n = 20) systematically. The training group program consisted of running on a treadmill for 30 minutes with an intensity of 55 to 60% of maximum heart rate. These training programs were continued three times a week for six weeks. The control group did not perform any exercise program. ELISA technique was used to measure lipid profile, liver enzymes, interlukin-6 (IL-6), and high-sensitivity C-reactive protein (hs-CRP), respectively. Results: The results showed that the variables of weight, liver enzymes, lipid profile, IL-6, and hs-CRP were significantly different from the pre-test (P < 0.05). Also, in between-group comparison, the results showed that except for the variables of fat percentage and BMI in the other variables of the study, a significant difference was observed (P < 0.05). Conclusions: The results of this study suggest that moderate-intensity endurance training could be used as a useful way to reduce weight, levels of inflammatory markers, liver enzymes and cardiovascular risk factors in people with a family history of CAD.
