The effect of different intensities of intermittent resistance training on inflammatory indices in obese men

The prevalence of obesity is one of the most important health issues in the world. The aim of this study was to determine the effect of intermittent resistance training with different intensities on the levels of interleukin-10 (IL-10) and interleukin-1 beta (IL-1β) in obese men.

In this study, 44 obese men (20-30 years old) were assigned into four groups of control, low-intensity intermittent resistance training, moderate-intensity intermittent resistance training, and high-intensity intermittent resistance training. Subjects trained for 12 weeks, 3 sessions per week with three different intensities (80% 1RM with 10 repetitions, 60% 1RM with 13 repetitions and 40% 1RM with 20 repetitions). IL-10 and IL-1β indices were measured 48 hours before the first and 48 hours after the last resistance training session.

A significant difference was reported in IL-10 and IL-1β levels between the intermittent resistance training groups with different intensities. After the training period, IL-1β had a significant decrease in the low (P=0.001), moderate (P=0.01) and high (P=0.001) intensity intermittent resistance training groups. A significant increase in the IL-10 was observed in the resistance training groups with low (P=0.01), moderate (P=0.01) and high (P=0.001) intensity.

According to the present findings, it may recommend intermittent high and moderate intensity resistance training as an effective method for treating obesity and having a favorable effect on its indicators.
