Experimental Study On The Effect Of Ballistic Training And Resistance Training On Lower Limb Explosive Strength Of College Basketball Students

Basketball is a high-intensity and confrontational collective sport,which has a very high requirement for the physical quality and strength quality of the athletes.As an important strength quality,lower limb explosive power is the key to determine the competitive performance of basketball players,and also an important factor affecting the outcome of basketball games.Through an 8-week training experiment,this study compared the influence of ballistic training and traditional resistance training on the lower limb explosive power of students specializing in basketball,analyzed the changes of test indexes of the two training methods before and after the experiment,and explored more scientific and efficient training methods,aiming at enriching the training means of lower limb explosive power of students specializing in basketball.This study adopted the methods of literature,expert interview,questionnaire,experiment and mathematical statistics.Twenty basketball students majoring in sports training at the Daily Campus of Shandong University of Physical Education were selected as experimental objects and randomly divided into the experimental group and the control group.The experimental group(N=10)received terminal release training intervention.The control group(N=10)received traditional resistance training intervention,which lasted for 8 weeks,twice a week.During the recovery and improvement stage,the training load was 30%1RM and the interval time was 180 s.In weeks 5-8,the training load was 60%1RM and the interval time was 180 s.Based on relevant literature and expert questionnaire survey,the final test indexes were determined as 3/4 sprint,half squat jump(SJ),squat jump(CMJ),standing long jump,one foot take-off height in run-up,vertical jump height in place and knee isokineic muscle strength.The experimental test data were sorted and analyzed by Excel and SPSS 26.0,and the experimental conclusions were drawn by intra-group paired sample T test and inter-group independent sample T test.Results:1.The experimental group achieved significant differences in 3/4 race sprint,half squat jump(SJ),squat jump(CMJ),standing long jump,one foot jump height in run-up,vertical jump height in place and knee joint isokinetric muscle strength indexes(P <0.01).2.In the isokinetic knee force test of the experimental group,the 180° peak torque and peak power of the left and right extensor muscles showed significant differences,and the growth value and growth rate increased significantly.3.The results of 7 test indexes in the control group were improved to some extent compared with those before the experiment,but there were no significant differences in3/4 race sprint,half squat jump(SJ),squat jump(CMJ),standing long jump,one foot take-off height in run-up and vertical jump height in place(P > 0.05),while there were significant differences in knee isokinetor muscle strength index(P < 0.01).Conclusions:1.Ballistic training can significantly improve the lower limb explosive strength of college basketball students,and the improvement effect is better than traditional resistance training.2.The ballistic training group improved the 180 peak torque and peak power of the left and right extensor muscles better than the traditional resistance training group,and the ballistic training was more conducive to improving the lower limb explosive strength.3.The training load of 30%1RM and 60%1RM in the ballistic training group is feasible and effective to improve the lower limb explosive strength of college basketball students.4.Ballistic training can improve the lower limb explosive strength of college basketball students in horizontal and vertical directions.
