title: Effect of single-session aerobic exercise with varying intensities on lipid peroxidation and muscle-damage markers in sedentary males.
abstract: OBJECTIVE
  This study was conducted to evaluate the effect of the different intensity levels of single-session aerobic exercise on serum levels of lipid peroxidation and muscle damage markers in sedentary males.
  
  
  METHODS
  Fifty one sedentary healthy males aged 21.76±1.89 years were randomly divided into four groups, with one control (n=10) and three treatment groups that attended single-session aerobic exercise with low (n=14), moderate (n=14), and high (n=13) intensities. The serum levels of malondialdehyde (MDA) and creatine kinase (CK) were measured.
  
  
  RESULTS
  Data analysis revealed a significant effect by the intensity levels of aerobic exercise on MDA (P=0.001) and CK (P=0.003) post-test when the participants in the treatment groups were compared with the control. When the intensity of aerobic exercise was increased, the amount of MDA and CK was also found to be increased.
  
  
  CONCLUSIONS
  Single-session aerobic exercise can increase the amount of MDA and CK, suggesting that low intensity level of aerobic exercise should be utilized for more adaptation, and to prevent lipid peroxidation and muscle damage in sedentary males.
