Response of adipose tissue-derived cytokines (CTRPs) to different intensities of resistance training in obese individuals

this study aimed to investigate the response of adipose tissue-derived cytokines (CTRP3 and CTRP5) to resistance training with different intensities in obese men.

44 obese men were randomly divided into 4 groups of 11: control, low-intensity exercise, moderate-intensity exercise and high-intensity exercise. The training program included resistance interval training including 8 movements which were performed in different intensities. The first sample was taken 72 hours before and the second blood sample was taken 72 hours after the 12-week training period from the subjects' right arm vein. In order to analyze the data, analysis of covariance, correlated t-test and Tukey's post hoc test were used at a significance level of P<0.05.

CTRP3 and CTRP5 levels in training groups were significantly different from the control group (P<0.001 and P<0.001, respectively). Also, the results of post hoc test showed that CTRP3 and CTRP5 levels in training groups were significantly increased compared to the control group. There was also a significant difference between low and medium intensity training groups and high intensity training groups (P<0.001 and P<0.001, respectively). There was a significant difference between low intensity training groups and high intensity training groups (P=0.028), also.

The results of the present study showed that CTRP3 and CTRP5 levels increased in the 12 weeks after resistance training, which could be related to a possible reduction in body fat percentage and body weight, which was more noticeable in the group with high intensity training.
