A Comparative Study On The Effect Of Children's Freestyle Swing Arm Technique And The Effect Of Articulated Arm Technique

This paper is a comparative study of two freestyle techniques.The purpose is to find out the technical structure of the freestyle and freestyle freestyle and their respective advantages and disadvantages and their respective advantages.Finally,the above two points to analyze the structural characteristics of the two technologies were on their own technical advantages and disadvantages of what impact.For children in freestyle technical practice and choice to open up new ways of thinking.Constructive suggestions on the innovation of freestyle technology.In this experiment,16 subjects were randomly divided into two groups,group A was the experimental group and group B was the control group.The total experimental period is 16 weeks.Using the group experiment,the two groups of small players after a period of time were "straight arm freestyle" and "flexion free freestyle" technology,and then the two groups in the 50 meters and 100 meters freestyle project to test;interception test " Frequency "," plan "," speed " three main indicators to compare and analysis.The results show that the straight arm freestyle technique has the technical characteristics of high frequency and low amplitude.2.straight arm freestyle technology easier to get started,suitable for freestyle beginners.3.Compared with flexion-free freestyle technology,straight-arm freestyle technology has limited room to rise.4.Straight arm freestyle is more advantageous in short run.5.Compared with the flexion and freestyle technology,straight arm freestyle technology to consume more energy.6.Arbitrong freestyle technology has the technical characteristics of low scrambling plan.7.flexion and freestyle technology in the action structure is more cumbersome,want to swim you need a long time to "polish".Suitable for advanced people with a certain freestyle basis.8.Compared with the straight arm freestyle,the flexor freestyle has a greater advantage over longer distances.9.Compared with straight arm freestyle,flexor free swimming skillsSurgery in the process of moving more economical.
