Myoelectric Analysis Of Zhangze' S Flat First Serve Comparative Study With Teenage Players' Flat First Serve In Jiangsu Province

Research purpose: using methods of wireless electric technology,combining with the sports anatomy,sports training,sports biomechanics,and other multi-disciplinary knowledge,will be a choice of flat first serve every tested body muscle activity such as specific information analysis based on this model.We will looking at five tennis players with similar body shapes to the model,and compare their service efficenacy against the “best serve model”.We will look to see where the differences are in relation to maximizing the full potential of the service action for elite tennis.thus to help coaches to develop targeted class from choose the shape of the youth players serve improvement plan play an important basic role.Research methods: using the world widely used methods of electric testing system and several young men's tennis athlete selection in piece of flat firing serve movement electrical test was carried out and recorded,and using special analysis software for each muscle activity state analysis under test.By using the methods of electric sensor have the characteristics of real time record analysis zhang choose flat,fire serve is mainly engaging in specific information,such as muscle activity and translated into subjects contribution rate of muscle in the chain of the overall power power,according to this model.Will work with zhang serve action of young people choose the figure almost all major muscle strength in the overall strength biggest contribution rate and the duration of muscle power,power sequence contrast with the model.Results: according to choose the flat zhang firing serve by muscle electromyography testing analysis found that the deltoid muscle and the muscles of the trapezius muscle were the first to participate in power,compared with other muscles in the overall muscle power,contribution is large,long time power at the same time,so is the main force of muscle.Conclusion: through daily technology involved in making a selection and physical training schemes and plans,according to the test of muscle electromyography data and analysis results,and to a similar youth players choose the figure put forward the corresponding suggestion,specific for:(1)flat firing serve movement of strength training should particularly strengthen deltoid,trapezius muscle fast these two pieces of muscle strength,power and endurance training;(2)pay more attention to teenage players serve power chain each muscle power order and coordination;(3)on the whole,in daily physical training can't ignore the coordinated development of all parts of the body muscle strength.
