THE INFLUENCE OF MYOSIN HEAVY CHAIN ISOFORM COMPOSITION AND TRAINING STATUS ON THE PATTERNS OF RESPONSES.

The article discusses a study to examine the influence of myosin heavy chain (MHC) isoform composition and training status on the mechanomyographic (MMG) amplitude versus isometric torque relationship for the vastus lateralis. There were no consistent patterns of responses for the resistance-trained, aerobically trained or sedentary subjects for MMG amplitude versus torque. The differences in MHC isoform composition and training status did not explain the torque-related patterns.
