笔者研读了郭雪奇等人在成都体育学院学报2009年第7期(37-39页),发表的《刘翔110栏分段时间与总成绩的相关关系研究》一文。该文结论认为,刘翔在全程跨栏跑中,栏间三步跑优势明显,过栏腾空技术不如国内外优秀运动员。本文通过分析认为郭雪奇等人结论不颇,与事实不符,刘翔的过栏腾空技术具有绝对优势,而其栏间三步在速度上不占优势。
The author studied Guo Xueqi and others in Chengdu Institute of Physical Education in 2009 No. 7 (37-39 pages), published “Liu Xiang 110 column segmentation time and the total score of” a text. The conclusion of the paper is that Liu Xiang has obvious advantages in three stages of hurdling in the whole hurdle, and the technique of hurdling through the hurdle is not as good as the outstanding athletes at home and abroad. In this paper, Guo Xueqi et al. Conclude that the result is not quite true, which is incompatible with the facts. Liu Xiang’s over-the-bar emptied technology has an absolute advantage, while the three-step method does not dominate the speed.
