Effect of Different Intensity Outdoor Tennis Training on Cardiac Load

Abstract

Starting from the outdoor tennis competition, this paper studies the load characteristics of tennis competition through the experimental test of outdoor tennis players. This paper mainly adopts four research methods: literature, experimental test, mathematical statistics and logical analysis. This paper analyzes the load characteristics of outdoor tennis players in singles through experiments on the characteristics of competition time, the changes of center rate in the process of competition and the changes of creatine kinase, blood urea and urinary protein before and after competition. The results showed that the content of creatine kinase in blood increased significantly and the protein in urine increased significantly. This shows that outdoor tennis competition is more intense. The increase of blood urea after competition shows that there is a certain load in outdoor tennis competition, but the load is relatively small. The small load is mainly due to the short time of outdoor tennis competition, so the content of blood urea will not increase significantly.
