MMG and EMG responses during 25 maximal, eccentric, isokinetic muscle actions.

Purpose: The purpose of this study was to examine the patterns of the mechanomyographic (MMG) and electromyographic (EMG) amplitude responses of the vastus lateralis (VL), rectus femoris (RF), and vastus medialis (VM) during 25 maximal, eccentric, isokinetic muscle actions.

Methods: Seven healthy adult females (22.1 +/- 2.

MMG and EMG responses during fatiguing isokinetic muscle contractions at different velocities.

The purpose of this study was to determine mechanomyographic (MMG) and electromyographic (EMG) responses of the superficial quadriceps muscles during repeated isokinetic contractions in order to provide information about motor control strategies during such activity, and to assess uniformity in mechanical activity (MMG) between the investigated muscles. Ten adults performed 50 maximal concentric muscle contractions at three randomly selected contraction velocities (60, 180, and 300 degrees.s(-1)) on different days.
