Research On The Influence Of Functional Strength Training On Special Quality Of Velocity,agility And S Trength Of Football U13 Adolescents

Football is a sport event that calls for intermittent,high strength repetitive sprint and frequent play switch along with fierce tackles,which requires players have decent physical conditions.It has been highly discussed in football field on how to promote players physical conditions effectively.Until now physical functional training has been applied in competitions such as table tennis,volleyball,badminton and diving,while inadequacy on football and combination with youth training system.That how to apply physical functional training to youth football training has become a problem we should cope with.This thesis has adopted Document method,Expert interview method,Experimental research method,Statistics method and Comparative analysis method to put world class physical functional training into football training and practicality,analyzing effect of juvenile football players' physical conditions in terms of physical functional training.55 U13 players were divided into experimental group and counterpart group and tested on 10 meters,30 meters,Illinois run,5 x 25 shuttle run,throw-in and point kick,6 indicator tests in total,then experiments on them with identical content but only one difference lies in additional 15-20 minutes functional strength training to experimental group.6 indicator tests again applied to the two groups of students after24 classes.Having analyzed the results the conclusions are as followed:1.A certain increase in 6 indicator tests of experimental group and counterpart group after experiments;significant difference in counterpart group comparing to prior 5 test results with the exception of throw-in;a significant difference between former test results and the latter in counterpart group;2.A significant difference between experimental group and counterpart group lies in 2indicator tests Illinois run and 5 x 25 shuttle run,which indicates functional strength training has a prominent bearing on promotion of youth agility capability.
