The effect of continuous swimming on physical health

Abstract

Using the literature, physical fitness test, mathematical statistics and other methods, researchers carried out body test and analysis of the swimming association members who have been swimming all the year round in Heyuan City. The results showed that after annual swimming, the BMI of swimmers was slightly higher than that of all the testers, and the vital capacity and the step index were significantly improved. The grip strength was significantly higher than that of all the testers, and the other qualities were not significantly improved. The two indexes of sitting body flexion and standing on one foot with closed eyes were lower than all testers; The overall physical fitness evaluation score is superior to all testers. The overall vascular elasticity of swimmers is better than that of all testers, and the anti-atherosclerotic ability is enhanced, but the low bone mass ratio of bone density is higher than that of all the testers. The author acknowledges that it is related to the lack of weight exercise in the water, and further research is needed.
