The Study Of Using Hip-stress Skill And Strength Training Method To Prevent Waist Injury And Improve The Effect Of Specific Strength Training

Introduction
Waist injury frequently occurs in conventional strength training is a stubborn problem to overcome. How to avoid or
eradicate waist injury while maintaining maximum training load has always been an important research subject in sports
medicine and sports training science. Accomplishing this study satisfactorily is of great significance to both improving
sports results and protecting athletes.

Methods
By using hip-stressed driving method, Sited forward press method and barbell squat method, 1 year period(quantity
load control) and 3 years period(non quantity load control) contrast experiment were conducted among 47 and 86
objects separately.
Results
2 (1 year period experiment) and 5 (3 years period experiment) waist injuries were occurred in barbell squat group.
None of waist injury was occurred in other two groups.

Discussion/ Conclusion
Hip-stressed strength training method places its stress point on front hip. Hip is a part of pelvis, which is strong and
steady, and can stand heavy load without being hurt. So it can improve lower-limb maximum strength rapidly without
waist injury. Its most prominent feature is that the stress point on body trunk is located on the hip-----the body gravity
center. This feature permits the lower-limb to drive and extend backward under a high intensity, and realizes the
agreement of force exerting direction with that of real running, jumping and throwing. With this feature, this
method
can achieved an unprecedented effect on specific strength training.
The hip-stressed driving method can effectively prevent waist injury and obviously increase the maximal driving power
of athlete.
