Research On The Relationship Between Special Quality Of Chinese Youth Badminton Athletes And Sports Achievement

Competitive sports are not only the competition of national science and technology,as well as economic comprehensive strength but also the embodiment of national spirit.For a long time,China’s badminton team has made great achievements in the Olympic field and international competitions.Badminton sport is an advantageous sport in China.However,it is worth the alarm that the Chinese team has failed in recent years reflecting the decline in the quality of talent reserve.Poor talent reserve has directly presented in the recent Olympic Games.At the 2016 Rio Olympics,China’s badminton team took only two gold medals and one bronze medal.Badminton’s advantage has become less and less obvious.Behind the development of the high level badminton players in the past three years,the shortage of echelon construction and talent reserve is an urgent problem to be solved.At present,the research on badminton is mainly focused on the various techniques and tactics of badminton,the analysis of play,the mechanics of badminton,and the research of badminton sport training.In the modern competitive sports arena,the competition has been more and more fierce,only the top talented athletes along with long-term scientific training have the opportunity to become the world champion.Therefore,the selection and cultivation of reserve talent should be the first.Through many years of practice in China,the indexes of the training and allocation test have been used for many years,but there is nearly no research on correlation between the sports quality of badminton and the performance of sports.That means the indexes system is lack of scientific verification and theoretical support between indicators and grades.Research purpose:With the development of badminton sport in the Olympic Games and the higher importance of the world competition,scientific selection has attracted more and more attention from all over the world.Through the research of the relationship between our country’s youth badminton athlete’s quality and sports scores,this study expects to find out special quality indicators,which can work in our youth badminton athlete’s pageant and cultivation.The study can provide support for China’s badminton scientific selection and result in better badminton selection practice.Objects and methods:For the 12-to 15-year-olds who have entered the finals of the national youth badminton championships in 2018,they are ranked in groups by cycling competitions,with 16 players in each group.Before the game,these athletes took a special quality test including 5000 m/3000 m,ten times of four point low center of gravity to touch the ball run,20 m x 5 run back and forth,ten times on both sides of the touch line run,standing long jump,3 minutes two-shake rope skipping.The data was compiled using Excel,analyzed through SPSS19.0 statistics.We conducted an ANOVA to see if there are any differences between different age groups in different projects.Correlation analysis and stepwise regression analysis are also conducted to find out indicators inflecting performance.In addition,a t-test was done to make sure if there are significant differences between the excellent half and the general half in the same age group.Results:(1)There was no significant correlations between physical fitness and athletic performance in male athletes aged 12 and 15.In 13-year-old group,there is a significant correlation between physical quality and performance.Height,weight,number of grams of Mr.Value,the performance of 20 m x 5 shuttle run and standing long jump,have significant correlations,correlation coefficient are respectively 0.611,0.629,0.596,0.629,0.521,p<0.05,and the weight and performance have very significantly negative correlation.For 14-year-old male badminton players,height,performance of standing long jump and performance have significant differences,the correlation coefficient r values are 0.624,0.526,p<0.05,weight has a negative correlation with performance,the r value is 0.624.(2)Female athlete at the age of 12-,14-,15-year-old group,physical quality indicators do not show significant correlation with performance.At the age of 13 group,the scores of 10 times low center of gravity four points run,20 m x 5 shuttle run and standing long jump,have significant(p<0.05)with performance,the correlation coefficient r value are 0.618,0.501,0.603,respectively.(3)Among 12 to 15-year-old male badminton athletes,only in 14 groups,whose average height was 174.71 cm,shows that the excellent group is significantly(p = 0.04)higher than the general one.For others,good group compared with general group,height,weight,Mr Index,10 times of low center of gravity four points run(s),20 m x 5 shuttle run(s),ten times on both sides of the touch line(s),standing long jump(m),these indicators in excellent groups are better than the general group.While in 5000m run,3000m run,excellent groups are worse than the general ones,though not statistically(p>0.05).(4)For female badminton players in the 12-year-old group,10 times of low center of gravity four points run(s),the excellent group score is 19.54s,significantly(p=0.03)better than the general group(20.43s).At age 13,there are multiple indicators having significant differences between the excellent group and the general group.For 10 times of low center of gravity four points run(s)excellent group is 18.49s,significantly distinguish from the general group(19.46s),(p<0.05);20 m x 5 round-run(s),excellent group gets 21.25s better than the general group(21.94s)(p=0.04);Standing long jump(cm).excellent group is 218.43cm better than general group(202.22cm)(p=0.02).Conclusion:(1)For badminton players with different genders and different ages,there are different quality indicators related with sport performance;(2)For the 13-year-old badminton players,both men and women,the scores of 20m x 5 round-run and standing jump are significantly correlated with the sports performance.(3)Among badminton players in the 12-15 years,there is no statistically significant differences between excellent group and general group in the endurance quality.(4)Male badminton players aged 12 to 15 years old,the kotai index and standing long jump indicators are closely related to the performance,which should be considered in the selection of reserve talents in the future.
