Effects of Three Different Modes of Exercise Training on Plasma Lipoprotein Profile in Healthy Men

Abstract

Objective: The present study was designed to compare the effects of resistance, endurance, and combined endurance / resistance exercises on plasma lipid and lipoprotein profile in healthy untrained middle-aged men. Methods: Healthy middle-aged staff of Islamic Azad University of Sanandaj were randomly assigned to eight weeks of three-times weekly endurance training groups (ET, 30.67±1.1 years, n = 10), resistance training (RT, 31.75±1.1 years, n = 10), combined endurance resistance training (ERT, 30.38±1.1 years, n = 10) and control (c, 30.38±1.1 years, n = 10). Subjects of ET, RT and ER groups underwent endurance (E), resistance (R) and combined endurance / resistance (ER) Original Research Article Mohammadi et al.; BJMMR, 6(5): 493-499, 2015; Article no.BJMMR.2015.225 494 training respectively. Control group subjects remained sedentary during the period of the study. Plasma lipids and lipoproteins were measured at baseline and at the end of the study. Results: Apolipoprotein B (apo B) decreased significantly (p =0.05) in ERT group. Triglyceride (TG) and LDL-cholesterol (LDL-C) decreased significantly (p =0.05) in both ERT and ET groups. High-density lipoprotein (HDL) increased significantly in RT group (p =0.05). Lipoprotein lipase, total cholesterol and apo A levels did not change significantly in none of the trained groups. Conclusion: Based on the results of the current study, ERT is the mode of choice for correcting plasma TG, LDL and apo B abnormalities, while RT works better for boosting HDL.
