The effect of eight weeks of concurrent training on insulin resistance and resistin and glucose plasma levels in middle-aged overweight and obese men

Overweight and obese people who do not engage in physical activity or exercise are usually at risk for certain metabolic, cardiovascular, and type 2 diseases, such as type 2 diabetes, coronary artery disease, and hypertension. The aim of this study was to investigate the effect of eight weeks of concurrent training (resistance and endurance) on insulin resistance and plasma levels of resistin and glucose in overweight and obese middle-aged men in Yasuj.

The research method was quasi-experimental with pre-test and post-test design.  The statistical population was overweight and obese men aged 30 to 45 years in Yasuj. The sampling method was purposeful and 30 people were selected as a statistical sample and were randomly divided into two groups of  concurrent training and control. The subjects in the experimental group performed 8 weeks of  concurrent training and 3 sessions per week. Data on insulin resistance,  plasma resistin and glucose before and after concurrent training were analyzed using Kolmogorov-Smirnov, dependent and independent t-tests at a significant level of p<0.05.

The results showed that insulin resistance, resistin and plasma glucose levels in the post-test in the experimental group were significantly reduced compared to the control group (p <0.05). In contrast, no significant change was observed in all variables in the control group (p > 0.05).

Therefore, it is can to suggest 8 weeks of concurrent resistance and endurance training that were performed in one session as one of the preventive and non-pharmacological methods to improve the metabolic, cardiovascular health status of overweight and obese middle-aged men.
