Correlation Analysis Between Special Physical Quality And Special Performance Of Elite Short Distance Speed Roller Skaters In China

Speed roller skating started late in my country.This competitive sport has the characteristics of high difficulty,strict technology and comprehensive quality requirements.At present,the State Sports General Administration has put forward the concept that the development of competitive sports should be in the same direction and synchronization with the national economic and social development.However,today’s short-distance speed roller skating in my country has a single training method and means,and special physical fitness training.For this reason,it is necessary to conduct further research on short-distance speed roller skating in my country.This study selects 28 athletes from the Suzhou Training Base of China Roller Skating Association as the test objects,and uses the methods of literature materials,expert interviews,questionnaire surveys,measurement methods,and mathematical statistical analysis methods to evaluate the special physical fitness of outstanding short-distance speed roller skating male athletes in China.To conduct research and analysis on the quality and special performance,establish the special physical fitness index system and special performance prediction model of my country’s outstanding short-distance speed roller skating male athletes,and provide a reference for evaluating the athletes’ special physical fitness development level and for the selection and training of athletes.The research conclusions are as follows:(1)Establish a special physical fitness index system for outstanding short-distance speed roller skating male athletes in my country,including 4 first-level indicators,6 second-level indicators and 13 three-level indicators.(2)There is a big difference in the specific physical fitness indicators of the outstanding short-distance speed roller skating male athletes in my country,and the athletes have a large space for development.(3)The special physical fitness indicators of my country’s outstanding shortdistance speed roller skating male athletes can be divided into four types of factors,in descending order of contribution rate:special speed strength factor,special whole body explosive force factor,special flexibility factor,special lower limbs factor explosive factor.(4)By using multiple linear regression,the ranking of the influence of the special physical fitness of my country’s outstanding short-distance speed roller skating male athletes on the special performance is as follows:speed skating 400-meter sprint between runs,30s bicycle average power,30-meter land run,sitting body Forward bend,squat vertical high jump,7-second power bicycle maximum power,maximum weight squat,deadlift,30S 30KG rocket push,high clean,single-leg sitting forward bend,single-leg side step jump,roller skating 100 meters start.And construct the special performance prediction model of my country’s outstanding short-distance speed roller skating male athletes:Y=0.821X2+0.027X10+0.004X11+0.779X12-13.135After testing,the prediction accuracy of the model is high.According to this model,it provides an objective basis for predicting the special performance of shortdistance speed roller skating male athletes and monitoring the development level of athletes’ special physical fitness.
