An Experimental Study Of Restrictive Aids To Standardize The Technical Movements Of Freestyle Beginners

Freestyle is the most important event in competitive swimming.In the Olympic Games,there are 32 swimming events,14 of which are freestyle.The competition includes starting,underwater legs,half way swimming,turning and so on.Half way swimming is the most important part.It’s an important time to show the technology.The world’s gold medal coach has emphasized that the improvement of performance is inseparable from technology,and all the world’s top swimmers have standard technical actions suitable for their own specialties.Professional athletes have long-term and systematic technical improvement plans in daily training.Therefore,professional athletes began to correct their skills in early childhood.This requires the ability of coaches,coaches are mostly retired athletes and professional sports college students.It is of positive significance to improve the technical level of students majoring in physical education.The limited auxiliary exercise equipment has positive influence on the specification of Freestyle entry,holding,pushing and air arm moving.The main reasons are as follows: first,the restrictive auxiliary practice can make students better master freestyle technology,and can use vision,hearing and noumenon feeling to realize the standards and errors of their own freestyle technology.Second,the limited auxiliary exercise device makes the students improve the freestyle technique more efficiently.Third,the equipment is easy for students to master and more convenient for teachers to guide and use.Fourth,the practice load of the restrictive auxiliary equipment is small and it can be practiced repeatedly.It is suitable for freestyle beginners to practice.It can be widely used in the classroom and popularized.By observing the training of freestyle technique of students majoring in physical education and social physical education in Harbin Institute of physical education,this paper finds out the existing problems of freestyle technique of students at present.This paper puts forward the hypothesis,designs the reasonable plan of improving methods and means of freestyle,and designs the limited auxiliary equipment,so that students can effectively improve freestyle technology.Through the methods of literature,experiment,statistics and video observation,this paper analyzes the technique of students’ freestyle under water and on water.Get the data,and then analyze the data.Through 16 weeks’ experiment,the students’ technique of entering water,swimming,holding water,pushing water and moving arm in the air have been improved.After the improvement of freestyle technique,the result of freestyle can be improved.The improvement of Freestyle technology can improve the freestyle performance in different distance,and the stability of Freestyle technology has a good effect on the long-distance freestyle performance.After the experiment,there is a significant difference in freestyle performance.To prove the feasibility of the plan of improving freestyle technique with the help of restrictive auxiliary exercises.
