Statistical Analysis of sling exercise Training on Swimmer’s Core Strength and Balance Ability Experiment

Sling training is a new type of physical training method, which can improve the strength of trunk core muscles, improve the balance of the body, maintain stability, control the body posture and control the center of gravity. Swimming is a sport in the water, which is different from land events. In the unstable sports environment of water, it reflects the importance of core strength. In the process of swimming, trunk muscle group, as the core part of the body, undertakes the role of stability, power generation and power transmission. In this study, the students in the swimming special class of the school of competitive sports of Beijing University of physical education were selected as the experimental objects for 8 weeks of suspension training. Through the tests of the core strength related indicators, body balance related indicators and special scores of the subjects who had undergone suspension training and those who had not undergone suspension training, the experimental test data were statistically processed and analyzed by using the statistical software spss19.0, the results show that the test indexes of the experimental group are significantly different. Suspension training is of positive significance to improve the core strength, balance ability and special performance of swimmers.
