Abstract: The research discussed the influence to bone biomechanical c haracter of the rat in growing period after excessively training.establish excessively training model of through jump training of the rat in growing pe riod.measuring the index include weight, hemoglobin, blood urea nitrogen,and te stosterone,Cortisol of the Rat after 8 weeks and measured the biomechanical cha racter of Femur at the same time.Result：(1) successively establish the rat excessively training model of jumping;(2)the growing of Femur of the rat was obviously restrained in y-axis;(3) ability of resisting destroy and distortion of the Femur of the rat depressed,and its brittleness increased and intensi ty descended.Conclusion：excessively training of jumping make the biomechanical character of femur of rat appearing the obvious descent.
Key words:excessively jumping training； rat； femur； bio mechanical character |
