Abstract
The aim of this study was to examine the effects of two kinds of concurrent training on body fat percentage, body mass index (BMI), maximal oxygen consumption, body upper strength, body lower strength, total cholesterol, Triglyceride and low- and high-density lipoprotein-cholesterol in non-athlete overweight boys. For this purpose, 40 non-athlete overweight boys (mean age 15.33 ± 0.58) were selected and assigned randomly to three groups: endurance interval and resistance training group (I+R, N=14, BMI=26.8±2.6), endurance continuous and resistance training group (C+R, N=14, BMI=26.10±2.1), and control group (C, N=12, BMI=27.3±3.2). The variables of body fat percentage, body mass index (BMI), maximal oxygen consumption, body upper strength, body lower strength, total cholesterol, triglyceride and low and high-density lipoprotein- cholesterol were measured at least 3 days before and after the training period. Paired t-test and one-way analysis of variance (ANOVA) and post hoc Scheffe test were used to analyze variables. The findings indicated that the (I+R) and (C+R) groups significantly increased their body upper and lower strength and significantly decreased their %BF and TG (p=0.001). LDL-C decreased significantly in the (I+R) group (p=0.001) and (C+R) group (p=0.009), but HDL-C increased significantly in the (I+R) group (p=0.000) and (C+R) group (p=0.003). It can be concluded that the concurrent interval or continuous and resistance training improve strength, maximal oxygen consumption, body fat percentage and lipid profiles in non-athlete overweight boys.
