Abstract
Background: Adipose tissue's phenotypic alteration due to exercise training is a new theory. However, the cellular–molecular mechanisms for these phenotypic alterations are not yet clearly
understood. The aim of this study was to investigate the effects of six weeks resistance training on Meteorin-like hormone level and insulin resistance index in overweight adolescent boys.
Materials and Methods: Twenty overweight adolescent boys (average age 18.5±1 years old, average weight 81.1±4.5 kg, and BMI 27.7±0.7 kg/m2) participated in this study. The subjects were randomly assigned into two groups: control (N=10) and resistance training (N=10). Subjects in training group performed six-week resistance training program 3 days/week. Anthropometrics parameters and fasting serum of Meteorin-like hormone levels, insulin and glucose were measured at the baseline and at the end of study.
Results: The level of Meteorin-like hormone was significantly decreased in control group (p=0.008), but that of Meteorin-like hormone in resistance training was increased insignificantly (p=0.311). The variations of Meteorin-like hormone levels between two groups were significant (p=0.004). The changes of insulin resistance were increased in both groups which were statistically significant (p=0.032) and insignificant (p=0.632) for control and training groups respectively. We found a negative and insignificant correlation between changes in Meteorin-like hormone levels and changes in insulin resistance index (p=0.273).
Conclusion: The results showed that six weeks’ resistance training has no effect on increasing Meteorin-like hormone serum level and improving insulin resistance index and body composition in overweight adolescent boys.
