Background. Type 2 diabetes mellitus (T2DM) is
a common metabolic disease associated with pathophysiological
changes in the neuromuscular system.
The present study aimed to investigate the effects
of a 6-week endurance training program on muscle
strength, electrophysiological parameters, and functional
activities in T2DM patients.

Methods. The study period was divided into 6 weeks
without training and 6 weeks with training. Twelve
T2DM patients participated in this study. During the
training period, the same T2DM patients went through
an endurance training program. The assessment process
included measurement of muscle strength, surface
electromyography (SEMG) recording, and functional
tests. Twelve healthy individuals were evaluated to
compare their data with the T2DM patients.

Results. The results showed that the muscle strength
and the amplitudes of the SEMG signals of T2DM patients
were lower than those of the healthy subjects.
The bioelectric activity of T2DM patients increased
after six weeks of the endurance training program. The
functional tests showed significant improvement after
the endurance training program in T2DM patients,
while no significant difference was observed between
the T2DM and healthy subjects.

Conclusions. The short-term endurance-training program
for lower limb muscles increased muscle strength
and SEMG amplitudes of the knee extensor and flexor
muscles and improved functional tests in T2DM patients,
which may be attributed to neural adaptation
after the endurance-training program.
