The median frequency immediately after the exercise was significantly
lower than the MF at the pre-exercise stage in all groups
(Fig. 7). There were significant differences between the MF
at pre-exercise and immediately after the exercise due to
fatigue in all groups (p < 0.005). The MF of all participants
recovered to the MF level of the pre-exercise during the
recovery period. At approximately 8 minutes and 10 minutes
after exercise, the MF of the nonstimulation group
was close to the MF at the pre-exercise stage. The MF of the
manual acupuncture group at approximately 6 minutes and
8 minutes after exercise was similar to the MF at the preexercise
stage. At about 4 minutes and 6 minutes after
exercise, the MF of the EMA group returned to the MF at the
pre-exercise. It was observed that the EMA group had a
significantly faster recovery time compared to the other
groups.
The results of the contrast test on the MF indicated that
the MF at 8 minutes after exercise in the nonstimulation
group was significantly recovered to the MF at the preexercise
(p Z 0.511). The MF at 6 minutes after exercise
was significantly closed to the MF at the pre-exercise in the
manual acupuncture group (p Z 0.530). In the EMA group,
the MF at 4 minutes after exercise was significantly similar
to the MF at the pre-exercise.
The peak torque of the three groups immediately after
exercise decreased significantly. However, we observed
that the peak torque did not increase up to the peak torque
at the pre-exercise until 20 minutes after exercise. As a
result, significant recovery was not found in all groups
(Fig. 8). The results of the contrast test on the peak torque
indicated that all three groups during the recovery period
did not recover to the peak torque at the pre-exercise
(p < 0.05).
