跑跳运动员脊柱腰段椎体形态和生理曲度的研究

Studies on the Morphologicak Characteristics and Physilogical Curvature of Lumber Spine of Athlete

本文用X线摄片法对照研究了跑跳运动员和普通大、中学生脊柱腰段的椎体形态和生理曲度。研究结果表明,运动员椎体高度的变化幅度大于普通学生。第五腰椎的垂直指数小于普通学生。脊柱腰段长度占身高的比例小于普通学生,显示出下肢长、躯干短的身材特点。用腰曲指数作为评价脊柱腰段生理曲度的指标,运动员和普通学生之间无显著性差异。

Applying radiograph, this paper studied the morphological and physilogical curvature of athlete compared with college and high-school students. the results showed that the variation of spine height is greater in athlete than in the students, vertical coefficient of the fifth lumber vertebra and rthe atio of the length of lumber spine and height is smaller in thlete than in students. The athlete had the stature characteristics of longer lower limb and shorter trunk. The index of curvature has no significant difference between athlete and students in the evaluation of physilogical curvature of lumber spine.
