The Effect of Aerobic Interval Training on Preptin, Lipid Profile and CRP Levels in Overweight Men
Main Article Content
Abstract
Background and Aim: Preptin is one of the hormones regulating energy consumption. Therefore, in this study the effect of aerobic interval training on serum preptin, lipid profile, and CRP levels was investigated in overweight men.
Methods: 24 volunteer overweight men who were able to participate in regular physical activities were chosen and were randomly divided into experimental (n=12) and control (n=12) groups. For 8 weeks, the experimental group exercised according to the training protocol 3 times per week. Changes in serum preptin, lipid profile, and CRP levels were analyzed before and after the training period using the covariance test at P <0.05.
Results: Intergroup comparison showed that preptin levels had no significant difference (P=0.067); however, CRP levels showed a significant decrease (P=0.048). Intragroup comparisons showed a significant decrease in preptin levels in the experimental group (P=0.042).
Conclusion: It seems that aerobic interval training can play a major role in weight control by reducing serum preptin and CRP levels and lowering some of the harmful indicators in lipid profile.
