Abstract
Background and Aim: Finding exercise training that has high and fast effectiveness can encourage obese people to do exercise. The aim of the research was to investigate the effects of twelve weeks of circuit and traditional resistance training combined with aerobic training on interleukin-6, tumor necrosis factor alpha and muscular strength in obese men. Materials and methods: 36 obese men with a mean ± standard deviation of age 25.75 ± 3.22 (years) and body mass index 35.13 ± 1.3 (kg/m2) were purposefully selected. The participants were randomly divided into three groups: control, traditional resistance training and circuit resistance training. The participants in the training groups first performed resistance training and then aerobic training for 12 weeks and three sessions per week. The intensity of the exercises was changed every four weeks according to the principles of overload and progression. To evaluate the differences between the groups, the statistical method of analysis of variance with repeated measures and Sheffe's post hoc test was used at the significance level of p<0.05. Results: Interleukin-6, tumor necrosis factor alpha, upper limb strength, lower limb strength and body weight had significant differences between the groups (p<0.001). Interleukin-6 (p<0.001) and tumor necrosis factor alpha (p=0.02) were significantly reduced in all training groups compared to the control group. However, upper limb and lower limb strength increased significantly in all training groups compared to the control group (p<0.001). Body weight decreased significantly only in the circuit resistance training group compared to the control group (p=0.01). Conclusion: Performing 12 weeks of traditional and circuit resistance training concurrently with aerobic training moderates the levels of inflammatory adipokines and improves muscular strength in obese men. But it is suggested to use circuit resistance training to lose more weight.
