Abstract

Through the analysis technology of surface electromyogram, the effect of superoxide dismutase combined with
kneading on eliminating athletes’ fatigue was quantified objectively, and the effect of superoxide dismutase
combined with kneading on eliminating athletes’ fatigue was analyzed effectively. 120 young students of a
exercise university were selected as experimental subjects. Three intervention measures were adopted to the
subjects: injection of superoxide dismutase, kneading method and combination of superoxide dismutase and
kneading method. According to the different intervention measures, the subjects were divided into three groups
(A, B and C) and a control group. Each group had 30 experimental subjects. Among them, group A was injected
with superoxide dismutase, group B was massaged by kneading, and group C was injection combined with and
kneading. Comparing the results of surface electromyogram of biceps brachii and quadriceps femoris in each
group, it can be seen that the increase of contraction time of biceps brachii and quadriceps femoris in group C
was higher than that in group A and B; the absolute value of median frequency, the absolute value of percentage
of change in median frequency, the absolute value of mean power frequency, the absolute value of percentage of
change in mean power frequency and the integral EMG values were significantly lower than those in group A
and B; and the indicators of biceps brachii and quadriceps femoris in group A, B and C were better than those in
control group. It shows that the combination of injection of superoxide dismutase and kneading can effectively
eliminate athlete’ s exercise fatigue.
