Comparison Of Isokinetic Measurement Of Trunk Strength Between Wushu Athlete And Normal College Student

Isokinetic technique is the shortened form of isokinetic testing for muscle and training,it is a new and high valuable technique for muscle function access and muscle function training.Isokinetic technique has been used in athletic sports broadly,this text is a research for the flexion and extension of the trunk of second group of wushu athlete and general undergraduate,provide a set of data,in order to give a plan to the training for the wushu athlete.The machine is system of ISO-MED2000,the objects are the muscle of flexion and extension of the trunk of 19 Wushu athlete and 10 general undergraduate.The 9 person is free fight of Wushu,the other 10 is series of skills and trick in wushu.The speed of the test is 30°/s 90°/s and 180°/s, every object completes the test kilter.And this text analysis the data of peak torque(PT),flexion/extension(F/E),maximum work(MW)and total work(TW)of the three groups,found the different between the wushu athlete and normal college student.Result:The peak torque of 30°/s of the three groups are significantly higher than that of 90°/s and 180°/s(p＜0.01).But there is no significantly different between 90°/s and 18°/s.The total work and maximum work have the same change trend with peak torque.In the same text speeds,the biggest peak torque,total work and maximum work of the flexion and extension is the group of free fight in the different three groups.the second is series of skills and trick in wushu.the third is the common group.The F/E of the three groups are all in 60%-90%.The normal college student group's F/E is higher than the other groups.In 30°/s, the peak torque,total work and maximum work of isokinetic eccentric is significantly higher than that of isokinetic concentric.Conclusion:1.The peak torque of the three groups is reduced with the increased speed of the test in some range.2.Under three different speeds,the biggest peak torque,total work and maximum work of the flexion and extension is the group of free fight. the second is series ot skills and trick in wushu.the third is the common group in the same text speeds.3.The F/E of the three groups are all regular.the normal college student group should increase their muscle strength of trunk.4.The peak torque,total work and maximum work's change trend are basically consistent.5.in the 30°/s,the muscle strength of isokinetic eccentric is significantly higher than that of isokinetic concentric.
