The Effect of Eight Weeks of Combined Training (Aerobic-TRX) and Cinnamon Supplementation on Serum Levels of Leptin and Visfatin in Inactive Overweight Women

Obesity and overweight have become a global problem. Obesity is increasing sharply, especially in Iranian women. Experts believe that diet and drugs alone are not enough to treat and control sugar and blood fat metabolism of patients, but physical and sports activities should also be added to the daily schedule.
The current research is a semi-experimental type with a pre-test and post-test design. 40 overweight women were randomly assigned to four groups of combined exercise, combined exercise-supplement , supplement and control. Aerobic training was performed for 8 weeks and three sessions per week with 50-75% of the maximum heart rate and TRX training in the range of 12 to 17 pressure perception on the Borg scale. 24 hours before the start of training and 48 hours after the end of the last session, blood was taken to measure leptin and visfatin. Then, analysis of covariance (Ancova) test was used for inter-group changes and paired correlation T-test for intra-group comparison. Data analysis was done by SPSS version 25 software at a significance level of P<0.05.
The results show a significant decrease in leptin (p=0.001) and visfatin (p=0.001) values, and the changes for the exercise and exercise-supplement group were more than the cinnamon supplement group.
According to the results of the current research and since combined exercise has a beneficial effect on leptin and visfatin compared to supplements, it can be recommended that overweight people use combined exercise to lose weight.
