title: Excess post-exercise oxygen consumption is not associated with mechanomyographic amplitude after incremental cycle ergometry in the quadriceps femoris muscles.
abstract: BACKGROUND
  The purpose of this study was to understand the relationship between the mechanical activities of the three superficial quadriceps muscles and excess post-exercise oxygen consumption (EPOC) after incremental cycle ergometer exercise.
  
  
  METHODS
  Twelve healthy male volunteers had mechanomyographic (MMG) and electromyographic (EMG) activity of the superficial quadriceps muscles recorded 30 minutes before incremental cycle ergometry and 60 minutes after the exercise work bout.
  
  
  RESULTS
  The results indicate significant time-constant values for EPOC and MMG amplitude for the three superficial quadriceps muscles during the 60-minute post-exercise recovery period. For EMG amplitude no decay patterns were found for the three muscles. In addition, there were no mean differences between the MMG values for the three muscles that were significantly different from EPOC.
  
  
  CONCLUSIONS
  These results suggest that EPOC after exercise could not be exclusively attributed to elevated activity of the working muscles.
