Effects of concurrent resistance-endurance training on body composition, lipid profile and blood glucose homeostasis in obese girls: A clinical trial

The prevalence of child and adolescent obesity is increasing rapidly worldwide. The objective of the present study was to investigate the effect of concurrent resistance-endurance trainings on body composition, glucose homeostasis, and blood lipid in obese girls.
In this clinical trial study, 20 schoolgirls volunteers (aged 13 to 15 years old) were randomly divided into experimental (n=10) and control (n=10) groups. The concurrent resistance-endurance training was performed for 12 weeks. The resistance trainings were conducted at 50% to 80% of one-repetition maximum (1RM), and endurance trainings were performed at 50% to 80% of target heart rate. Blood samples and body composition were measured before and after training. Data were analyzed by paired sample and independent t-test at α ≤ 0.05 significance level.
The results showed that significantly decreased in body mass index (P=0.03), weight, fat percent, subcutaneous fat (P=0.001), hemoglobin A1c (P=0.02), and increase in high-density lipoprotein (P= 0.02), but low-density lipoprotein, cholesterol, triglyceride, fasting blood sugar, and plasma insulin did not change significantly (P> 0.05).
It seems that 12-week concurrent training can desirably improve body composition, hemoglobin A1c, and high-density lipoprotein in obese girls
