| Young basketball players are in a critical period of mastering basic skills,and it is particularly important to cultivate their space creativity at this stage.Every shot in the game needs to create a favorable space to finish shooting by using various methods.The defender needs to restrain the opponent from creating shooting space by constantly using different defensive strategies to limit the opponent’s score.Therefore,the research and practice of youth basketball players’ jump shot space creation methods have certain practical significance.This paper takes the method system construction of young basketball players’ jump shot space creation as the research object.The research methods are literature,Delphi,experiment,and mathematical statistics.First of all,on the basis of consulting the relevant literature,using the Delphi method,we screened out the indicators of youth basketball players’ jump shot space creation methods,and constructed a method system of jump shot space creation that conforms to the characteristics of basketball;Secondly,according to the method system constructed,the training program is designed,and 12 young male basketball players are selected for a 12-week experiment,using independent sample T-test and paired sample T-test for data analysis,to verify the feasibility and effectiveness of the method system construction of jump shot space creation for young basketball players;Finally,the paper puts forward some training suggestions on the creation of jump shot space for young basketball players.The research,this purpose is to improve the ability of young basketball players to create space for a jump shots,and provide references for young basketball players’ jump shot training.The results and conclusions of the study are as follows.Results:(1)The method system of young basketball players’ jump shot space creation: the first level indicators are speed difference,height difference and position difference;The second level indicators are movement speed,movement speed,reaction speed,spring explosive force,height,technical movement dexterity,technical movement range and confrontation strength;The third level indicators are release speed,take-off speed,speed change of dribbling,breakthrough speed,speed of dribbling quick stop and jump shot,speed of receiving quick stop and jump shot,speed of dribbling,speed of running without the ball,speed of reaction without the ball,speed of reaction with the ball,height of jump,ability to stay in the air,feint,use of no ball movement to get rid of the defense,use of dribbling to get rid of the defense,use of holding the ball to get rid of the defense Horizontal movement range,vertical movement range,back to defender confrontation,side to defender confrontation and dribble confrontation between moves.(2)From the comparison of the test index data before and after the experiment in the experimental group,we can see that the five indexes,including the hit rate of the jump shot,the speed of the jump shot,the vertical movement range,the eight level abdominal bridge and the effect of space creation of jump shot,are significantly improved after the experiment compared with before the experiment through the statistical T-test,P<0.01;The turn back running speed and the jumping height of the cushion step were significantly improved after the experiment compared with those before the experiment through the statistical T-test,P<0.05;There was no significant difference between the two indexes of vertical jump height and lateral movement amplitude after the experiment and before the experiment,P>0.05,according to the statistical T-test.(3)From the comparison of the test index data before and after the experiment in the control group,we can see that the hit rate,jump shot speed,turn back running speed,standing vertical jump height,cushion jump height,horizontal movement range,vertical movement range,and eighth-grade abdominal bridge have all improved,but through the statistical T-test,P>0.05,there is no significant difference compared with that before the experiment;The score of the evaluation index of the effect of jump shot space creation,through the statistical T-test,was P<0.05,which was significantly higher after the experiment than before.(4)From the comparison of the results of the experimental group and the control group,it can be seen that the hit rate and eighth-level abdominal bridge are two indexes,and the statistical t-test shows that P<0.01,the experimental group was significantly higher than the control group;The four indexes of jump shot speed,turnaround speed,longitudinal movement range,and creation effect of jump shot space were tested by t-test,P<0.05,the experimental group was significantly higher than the control group;The three indexes of vertical jump height in place,jump height of cushion step and lateral movement amplitude were tested by t-test,P>0.05;There was no significant difference between the experimental group and the control group.Conclusions:(1)Through the issuance of Delphi expert questionnaire and recycling,build the youth basketball athletes jumper space creation method system,the system consists of three primary indexes(using the velocity difference to create space,using the position difference to create space,and the use of height difference to create space),eight secondary indexes and 21 tertiary indicators.(2)Through the index weight calculation of the constructed method system for the creation of jump shot space for young basketball players,the order of weight value and importance of the first-level index is "A speed difference" > "B position difference" > "C height difference".(3)According to the constructed method system of creating jump shot space for young basketball players,a training plan was made and a 12-week training intervention experiment was conducted.The experimental results showed that the training plan had a certain effect on the creation of jump shot space for athletes.(4)The experimental results verify the feasibility and effectiveness of the method system of jump shot space creation. |
