Introduction: Approximately 30% of overweight and obese children display an adverse lipid profile. Most studies show that aerobic training has the potential capacity in changing the body composition and lipid profile.Therefore, the objective of this study was to investigate the effect of two types of moderate-intensity continuous training (MICT) for ten weeks on lipid profile in overweight adolescent boys.
Methodology: Twenty-eight obese or overweight adolescent boys (12-15 years, and body mass index (BMI) ≥ 25 to 30 kg.m2) were randomly assigned into two groups: MICT-1 group [30 minute aerobic training per day (rgnning), three days per week at 65–70% HRmax] and MICT-2 [20 minute per day, four days per week at 65–70% HRmax] group. The serum triglyceride (TG), high-density lipoprotein (HDL-C), low-density lipoprotein (LDL-C) and total cholesterol (TC) levels were measured before and after the aerobic training protocols. Also, body composition was measured using skin fold thickness method. For statistical data analysis, the independent and paired sample T-test at p˂0.05 was applied.
Results: The results showed a significant reduction in body fat percentage, TC and LDL-C after the 10 weeks MICT in both training groups (P<0.05). Although, there was not significant difference between the two training groups (P>0.05). In addition, there was not significant difference between groups in HDL-C and TG levels (P >0.05).
Discussion: These findings suggest that both of two types of MICT training for 10 weeks have beneficial effects on lipid profile and body fat percentage in healthy overweight adolescent boys.
