Technical Analysis Of 50m Breaststroke Start

This paper makes a systematic observation,arrangement and analysis of the starting technique of the 50 m breaststroke of the Chinese elite female swimmer Suo Ran through the methods of literature,video observation,data processing and interview.This paper comprehensively reflects the advantages of the starting technology,finds out the characteristics of the starting technology of Suo Ran breaststroke,and determines the best starting method of Suo Ran in the competition.It provides training basis and reference for her to integrate the best technology in training and competition and further improve her overall swimming skill level.Based on the analysis of 50 m breaststroke starting technology,taking Suo Ran as an example,the following conclusions are drawn: 1.Good starting technology has six factors: higher horizontal speed of departure,faster starting,higher stability of preparatory posture,larger flight distance,reasonable jumping angle and angle of entry,and smaller water resistance.2.The advantage of the start technique is that the start reaction time is between 0.66s-0.70 s,and there is obvious characteristics of continuous abdominal force in the stage of takeoff.A good feeling of entering the water body can control the depth of entering the water and a small resistance;its disadvantage is that the technical action of long stroke in the water is not perfect,which affects the underwater body posture.3.Suo Ran own advantages include strong explosive power,excellent performance of back and abdominal endurance in 128 s and52s,30 minutes of heel closing in breaststroke in ankle test,excellent physical and psychological quality.Its disadvantages are high body fat and general recovery ability.The above disadvantages are easy to affect sports performance and lead to movement instability.4.The weight has an effect on the starting technique in the stage of starting and stretching.The poor angle will affect the air posture,the time of taking off and the distance of entering the water.5.The factors that affect the starting technique of swimming are physical quality.In addition to the importance of strength and explosive force to the starting result,the rationality of the inclined street of the starting technique in each link and various influencing factors are also important factors to determine the results of the competition.According to the above conclusions,the following suggestions are put forward: 1.In the breaststroke starting training,Suo Ran should shorten the underwater sliding time,improve the long water sliding arm movement,and help him to feel the continuity between chest and hip when he moves forward along the short axis through the water grabbing exercise,so as to increase the speed of water drawing.2.To control the body fat rate and increase the core physical training is conducive to maintaining a good body shape and streamline of the starting technical movement,and enhancing the application effect of rowing and kicking.Indirectly help them to improve their fast explosive power and comprehensive quality ability in swimming.3.In order to obtain the rebound force and speed,Suo Ran used the body weight to exert the force on the starting platform and contracted centripetally at the same time.4.Adopt diversified training methods,effectively combine water training with land training,effectively combine strength training with endurance training and speed training,and effectively combine high-intensity training with low-intensity training,so as to improve body feeling and body coordination ability.5.Increase Suo Ran nutrition supply,protein powder,oligosaccharide and water supply,increase rest and recovery time,and ensure its 50 meter breaststroke starting technology to be stable and super level.
