With the development of the times, sports fitness has gradually become an important part of people's
lives in China, and the good fitness of human sports has long aroused the attention of academia. However, the
accumulation of free radicals will slow down the body's metabolism, accelerate the body's lipid peroxidation
process, and eventually lead to cell damage, affecting the quality of life of modern people. The purpose of this
article is to study the effects of exercise training on the metabolism of free radicals in the myocardium, liver and
quadriceps of mice. This article first analyzes the theory of free radicals, and then studies the effects of exercise
training on free radicals. In the experimental part of this paper, 18 healthy mice were used as the research object,
and they were randomly divided into a quiet control group (S group), a continuous training group (C group) and
a long rest training group (Group I), a total of 3 groups, 6 in each group. Group S does not exercise, group C
trains once a day for 40 minutes, group I trains 2 groups a day, each group trains for 20 minutes, and rests
between groups for 3 hours. After six weeks of training, MDA, SOD and T-AOC were measured in the
experimental mice. The experimental results prove that long-time exercise is more beneficial to the metabolism
of free radicals than the continuous group and the control group. Compared with the control group, the MDA,
SOD and T-AOC values of the long rest training group were extremely significant (P <0.01).
