Background and Objective: 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.Materials and Methods: 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.Results: 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.Conclusion: 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.

Methods and materials: The method was semi experiment and the statistical sample consisted of 850 female staff in Sabzevar University of Medical Sciences in 1391 in which 57 female staff was randomly selected among them. They were divided into 3 groups (19 persons). Aerobics and yoga exercises were held at 8 weeks, 3 times a week for 60 minutes each time. The tools for gathering the data were a standardized questionnaire of self-efficacy (GSE) Schwarzer. For analyzing the data, t-test with a significant level of 0/05 was used.
Findings: The results showed that between yoga and control groups, there were significant differences in the posttest (p=0/562) whereas there was no significant difference between aerobic and control groups (p =0/035) as well as between yoga group and aerobics group (p=0/002).
Conclusion:The results showed that aerobic exercises didn't have any significant improvement on efficacy of female staff in Sabzevar University of Medical Sciences. It also showed that yoga exercises caused increasing efficacy in female staff in Sabzevar University of Medical Sciences.
