The Effect of Interval Training on Serum Meteorin-Like Hormone (Metrnl) Level in Overweight Adolescent Boys

Effects of phenotypic changes in adipose tissue due to exercise training are a new theory. However, the cellular– molecular mechanisms for these phenotypic changes are not yet clearly understood. The aim of this study was to investigate the effects of sprint interval training on serum Meteorin-like hormone level in overweight adolescent boys.

Twenty overweight adolescent boys (aged: 18.0±1.5 year, weight: 81.8±4.3 kg, BMI: 27.6±0.8 kg/m2) voluntarily participated in this study. Then, the subjects were randomly assigned into two groups (n=10). Subjects in training group performed six weeks’ sprint interval training program 3 days/week. Anthropometrics parameters and fasting serum lipid profile, insulin, glucose, and Meteorin-like hormone levels were measured at the baseline and at the end of study. Data analysis was performed with p values

The serum level of Meteorin-like hormone was significantly increased after six weeks’ sprint interval training.

The results showed that sprint interval training can change circulating Meteorin-like hormone level and improve insulin resistance index and body composition in overweight adolescent boys.
