Study On The Correlation Between The Five Elements Of Loop Drive And The Performance Of Young Table Tennis Players

The youth table tennis players are in a period of continuous development of technique,mind and body,and their performance will be affected by many aspects.However,mastering technique is the premise of executing tactics,and it is also the externalization of players' competitive ability in the competition.Therefore,to explore the correlation between hitting elements and the performance of young table tennis players,and to explore the development rules of technical elements at different age stages,can better guide the training scientifically.This paper the hitting elements of teenager loop drive are selected as the research object.And the research was carried out by methods of literature reviews,mathematical statistics,experimental method,and logical analysis.A total of 34 youth players from China table tennis college were divided into 6 groups: male and female U12,U15 and U18.A quantitative measure of a youth players making top spin and under spin with forehand and backhand separately.The measured results of each group were analyzed by one-way anova,and then the correlation analysis and regression analysis were conducted between the measured results of each group and their performance.Findings:(1)The correlation coefficient of spin in male U12 group was 0.213(P<0.01),the correlation coefficient of velocity was 0.445(P<0.01),and the correlation coefficient of falling point was 0.343(P<0.01);The correlation coefficient of spin in U12 female group was 0.345(P<0.01),and the correlation coefficient of arc was 0.331(P<0.01).According to the case analysis,the main winning factors of the loop drive technique of U12 men's group in the competition are falling point,spin and speed.The main winning factors of loop technique in U12 women's group are spin and arc.(2)The correlation coefficient of spin and velocity in male U15 group was 0.116(P<0.05)and 0.134(P<0.05).The correlation coefficient of spin in female U15 group was 0.695(P<0.01),the correlation coefficient of velocity was 0.441(P<0.01),the correlation coefficient of falling point was 0.374(P<0.01),and the correlation coefficient of arc was 0,285(P<0.01).Combined with case analysis,it was found that the winning factors of U15 men's loop drive technique were spin and speed.In U15 women's group,the winning factors of loop drive technique are spin,speed,falling point and strength.(3)The correlation coefficient of spin in male U18 group was 0.185(P<0.01),and the correlation coefficient of drop point was 0.114(P<0.05).The correlation coefficient of spin in female U18 group was 0.353(P<0.01).Combined with the case analysis,it is concluded that spin and falling point are the main winning factors of the loop drive technique of U18 men's group.The main winning factors of the U18 women's loop drive is spin.(4)The coefficient of determination between the hitting elements of U12 and the score of the match was 0.356 for men and 0.304 for women.The coefficient of determination between the hitting elements and the result of the match in U15 men's group was 0.054,and that between the hitting elements and the result of the match in U15 women's group was 0.534.The coefficient of decision of U18 men's hitting elements to the result of the competition is 0.075,while the coefficient of decision of U18 women's hitting elements to the result of the competition is 0.310;(5)The difference of hitting elements between male and female youth athletes in different age groups was P<0.05,except for the curve elements in male athletes of different age groups,P>0.05.There was no significant difference in rotation,speed and strength between U15 and U18 groups in the female group P>0.05.Conclusions:(1)The factors of the falling point,spin and speed of U12 men's group were positively correlated with the competition results.The spin and arc of U12 women's group had a positive correlation with the competition results,but here the arc was positively correlated,and it was believed that the more stable the arc was,the better the competition results would be.(2)There was a positive correlation between the spin and speed of U15 men's group and the result of the competition;The falling point,spin,speed and strength of the U15 women's group were positively correlated with the result of the competition.(3)There was positive correlation between falling point and spin of U18 men's group and the result of the competition.There was a positive correlation between U18 women's spin and performance.(4)The influence of hitting elements on the results of the U12 men's group and the U12 women's group was 35.6% and 30.4% respectively.In the U15 men's group,it was 5.4%,and in the U15 women's group,it was 53.4%.In the U18 men's group,it was 7.5%,and in the U18 women's group,it was 31.0%(5)There were significant differences in the hitting elements between youth athletes in different age groups,except for the curve elements of male athletes in different age groups.Among them,the hitting elements level of male athletes gradually increased from U12 group to U18 group.In women's group the level of spin,speed,power in the U15 group and the U18 group being basically the same.
