This study tested the hypothesis
that fatigue of a single member of musculus quadriceps femoris (QF)
would alter use of the other three muscles during knee extension
exercise (KEE). Six men performed KEE with the left QF at a
load equal to 50% of the 4 × 10 repetitions maximum.
Subsequently, electromyostimulation (EMS), intended to stimulate and
fatigue the left m. vastus lateralis (VL), was applied for 30 min.
Immediately after EMS, subjects repeated the KEE. Transverse relaxation
time (T2)-weighted magnetic resonance images were taken before and
after each bout of KEE and at 3 and 30 min of EMS to assess use and
stimulation, respectively, of the QF. T2 of each of the QF muscles was
increased 8-13% after the first KEE. During EMS, T2 increased

Subsequently, electromyostimulation (EMS), intended to stimulate and
fatigue the left m. vastus lateralis (VL), was applied for 30 min.
Immediately after EMS, subjects repeated the KEE. Transverse relaxation
time (T2)-weighted magnetic resonance images were taken before and
after each bout of KEE and at 3 and 30 min of EMS to assess use and
stimulation, respectively, of the QF. T2 of each of the QF muscles was
increased 8-13% after the first KEE. During EMS, T2 increased
( P < 0.05) even more in VL (10%), whereas it
decreased ( P < 0.05) to pre-KEE levels in m. vastus
medials (VM) and m. rectus femoris (RF). The VL and, to some extent,
the m. vastus intermedius were stimulated, whereas the VM and RF were
not, thereby recovering from the first bout of KEE. Isometric torque,
initially 30% of maximal voluntary, was reduced to 13% at 3 min and
7% at 30 min. T2 was greater ( P < 0.05) after the
second than the first bout of KEE, especially the increase for the VM
and RF. These results suggest that subjects were able to perform the
second bout with little contribution of the VL by greater use of the
other QF muscles. The simplest explanation is increased central command
to the QF such that the intended act could be accomplished despite
acute fatigue of one of its synergists.
