The Protective Effect of Interval Exercise on Myocardial Ischemia-Reperfusion Injury in Players.

In recent years, the popularity of sports has been increasing. In the high-intensity competition, many players have been injured; most of them are myocardial ischemia. With the development of medical science and technology, myocardial ischemia can be reperfusion. However, sometimes, the function of tissues and organs cannot be restored, but the dysfunction and structural damage of tissues and organs can be aggravated. Therefore, it is necessary to actively carry out intermittent exercise to protect players from myocardial ischemia-reperfusion injury. The purpose of this paper is to explore the protective effect of intermittent exercise on the myocardial ischemia-reperfusion injury of players. 60 clean male Sprague Dawley (SD) old rats were selected as the research objects, which were divided into control group, ischemia/reperfusion model group, intermittent exercise + model group, and intermittent exercise + control group, and compared the parameters of heart function indexes of each group. The results showed that the creatine kinase (CK) content of control group was 0.577 ± 0.176 u / ml , lactate dehydrogenase (LDH) content was 7.834 ± 1.507 u / ml , model group was 1.257 ± 0.113 u / ml , lactate dehydrogenase (LDH) content was 14.441 ± 1.793 u / ml , intermittent exercise + model group was 0.987 ± 0.127 u / ml , lactate dehydrogenase (LDH) content was 11.714 ± 3.017 u / ml , intermittent exercise + control group was 1.103 ± 0.125 u / ml , and lactate dehydrogenase (LDH) content was 14.647 ± 2.575 u / ml. It can be seen that intermittent exercise has a good protective effect on myocardial ischemia-reperfusion injury. If the interval exercise method is integrated into the daily training of athletes, it can effectively improve the perfusion injury caused by myocardial ischemia. [ABSTRACT FROM AUTHOR]
