Research On The Characteristics Of Physical Ability Structure Of Excellent Male Shuttlecock Athletes In My Country

Research purposes: Shuttlecock,as a competitive sport,requires athletes to transform offense and defense through skilled techniques in antagonism.When measuring the physical fitness level of elite male shuttlecock players in China,not only athletes need good strength and endurance,but also athletes need to be able to respond quickly and move quickly in the changing arena.This paper studies the body shape,physiological function and sports quality of elite male shuttlecock players by putting forward opinions,investigating,sampling and analyzing,and using actual data.Finally,through repeated verification and testing,the ideal physical structure model of Chinese elite male shuttlecock players is established,which provides theoretical basis for the selection and training of Chinese shuttlecock players.Objectives and Methods: The shuttlecock team of Tianjin Institute of Physical Education and some shuttlecock athletes of Shenzhen City,Guangdong Province,were investigated.The total number of athletes was 16.All of them had participated in the World Shuttercock Championships,the National Shuttercock Championships and the National University Shuttercock Championships,and achieved Championship results.Twelve of them had the experience of national team members.This paper uses literature review as the theoretical basis,questionnaire survey as the practical basis,and Delphi method to determine the test indicators.The index data are obtained by using the test method.Using factor analysis,mathematical statistics,logical analysis and other methods to complete the relevant analysis and research.Research results: Through the methods of literature,questionnaire and mathematical statistics,the index of physical structure model of elite male shuttlecock players in China is determined,and the detailed measurement method is formulated according to the index.According to the test results,this paper analyzed the physical structure characteristics of elite male shuttlecock players in China.At the same time,according to different positions and different responsibilities,the athletes were divided into setter position,main attack position and assistant attack position.The physical structure characteristics of elite male shuttlecock players in China are analyzed by classification.It is concluded that the height of Chinese elite male shuttlecock players is generally between 176 cm and 188 cm.The lower limbs are slender,the lower legs are long,the body is symmetrical and thin,the weight is slightly lighter,the weight of fat-free is slightly heavier,and the Achilles tendon of the lower leg is longer and clear.The physiological function is characterized by excellent cardiopulmonary function.At the same time,in terms of physical fitness,Chinese elite male shuttlecock players show a very high level in strength,speed,endurance,flexibility,sensitivity and other physical fitness.Shuttlecock players in the second pass position are more sensitive and responsive.Shuttlecock players in the main attack position and the secondary attack position have more outstanding movement speed,reaction speed and flexibility.Factor analysis was used to reduce the dimension of the indexes screened by experts.Nine main factors,including body circumference factor,body length factor,structure proportion factor,cardiopulmonary function factor,cardiac function factor,strength factor,flexibility factor,speed factor and sensitivity factor,were obtained.At the same time,through orthogonal rotation with Kaiser standardization,the typical indicators of nine factors,such as Ketoley index,lower limb length,lower limb length ratio height,maximal oxygen uptake,cardiac function index(30 seconds and 30 squats),in situ vertical jump touch height,vertical fork,one minute treadmill,4X10 m turn-back run,were obtained.The percentile method is used to establish the grade evaluation of different positions of elite male shuttlecock players in China.Through the viewpoint,investigation,sampling analysis and long-term experimental verification,the physical structure model of elite male shuttlecock players in China is analyzed,and the physical evaluation system of Chinese shuttlecock players is constructed.In the process of training and selecting the reserve strength of shuttlecock events by teaching and research personnel in the future.It can be used.
