Effects of 10-Week Concurrent Training on Insulin Resistance and the Serum Levels of Vaspin and Visfatin in Overweight Females

Aims The present study investigated the effects of a 10-week concurrent training on the serum levels of vaspin and visfatin in overweight females.  Methods & Materials Twenty-four over-weight females from Kerman City, Iran (Mean±SD age: 11.23±0.62 years; Mean±SD weight: 64.83±2.70kg; Mean±SD BMI: 27.97±0.47 kg/m2) were randomly assigned into the control and concurrent training groups. The intervention group performed the training protocol as follows: endurance training: 65-85% of Vo2 max for 20 minutes per session, and resistance training: 50-60% of One Repetition Maximum (1RM) for 30 minutes per session and 3 days a week for 10 weeks. Fasting plasma vaspin, visfatin, and insulin levels were measured by ELISA method. To analyze the data, Analysis of Covariance (ANCOVA) was used. Findings Performing 10 weeks of concurrent training significantly decreased vaspin and visfatin plasma levels, and insulin resistance resting levels (P≤0.05); however, there was no significant decrease in glucose levels.  Conclusion Concurrent training can decrease insulin resistance, probably by reducing vaspin and visfatin in overweight females. Therefore, it is suggested that overweight females use concurrent training to improve insulin sensitivity and prevent metabolic diseases.
