The heart is one of the most important organs in human body. In general, we generally believe that exercise can
enhance the strength of the heart and keep it healthy. However, many athletes are accompanied by cardiac
diseases such as cardiac hypertrophy and heart failure, and even have the risk of sudden death. In view of this
phenomenon, there have been relevant studies abroad, which are defined as “athlete’s heart”, and think that
overload sports will increase the probability of suffering from heart disease. Exercise has become a
double-edged sword in heart health, but there are few studies on the changes of left ventricular morphology and
function after exercise. So far, this paper uses the quantitative detection method of ultrasound biomicroscopy to
conduct in-depth study. The research of this paper is mainly divided into three parts. The first part is the research
of basic theory and core concepts. Through the research, this paper believes that the effect of exercise on the
heart is not absolute, different training methods will get different results; using reasonable exercise program is
the premise of maintaining heart health. The second part is to establish the experimental model of rats. In this
paper, 40 adult rats were used as experimental samples, and they were randomly divided into exercise group and
control group, with 20 in each group. In the third chapter of this paper, the experimental methods and specific
operation steps were given in detail. The third part is the experimental results and analysis. In this part, a
number of comparative experiments including cardiac function test were carried out in rats. Through the
analysis of experimental data, we can see that exercise is the main cause of heart failure in experimental rats, but
exercise can also make the rats recover to the indicators before heart failure, which further proves that
reasonable exercise can maintain heart health.
