Abstract

Introduction: Obesity is a type of malnutrition in which the accumulation of fat is so high that the functioning of the body's systems is disrupted. This study aimed to investigate the effect of 8 weeks of aerobic exercise on the indicators of triglycerides, cholesterol, HDL, LDL, and hyperglycemia in overweight men. Research Method: 40 overweight men (with an average height of 178±5.61 cm, weight of 99±0.89 kg, and BMI of 30.79±2.91 kg.m²) from the General Department of Education of Qazvin province with three simple random sampling methods were selected and randomly divided into two groups of control and aerobic exercise. During the eight-week experimental study period, aerobic exercise three times a week from 65% at the beginning to 85% at the end of the week was administered for subjects in the related groups. To evaluate biochemical variables, blood sampling was performed after 12-14 fasting hours in two stages, i.e. before the start of training and after eight weeks of training as pre-test and post-test, respectively. Results: After testing the research hypotheses by covariance analysis method, the results showed that eight weeks of aerobic exercise did not have a significant effect on the number of triglycerides and LDL in overweight men (P> 0.05). Eight weeks of aerobic exercise also had a significant effect on HDL, cholesterol, and blood glucose levels in overweight men (P <0.05). Conclusion: The findings suggest that aerobic exercise affects the indicators of triglycerides, cholesterol, HDL, LDL, and hyperglycemia in overweight men.
