摘要
目前国内外的游泳书籍和教材中 ,在分析划水技术力学时存在着基本概念上的认识误区。文章就“伽利略变换”相对运动原理应用问题和游泳力学分析参照物的确立问题进行了重新分析 ,认为 :(1)游泳时人体的躯干与手臂是协同产生内力的整体 ,采用“伽利略变换”相对运动原理分析游泳技术受力情况时 ,必须把人体看成是不动的 ,把水看成是流动的 ;(2 )
There are some misunderstandings on basic conceptions of swimming in books and teaching materials. The objective of this study was to analyze the problems on application of opposite sports theories and the object of reference on mechanical analysis in swimming. The results suggested: The body and the arms had synergetic effect on producing the power and should be considered as a whole, the swimmer should be regarded as motionless object while water as active one when analyzed the swimming technique using opposite sports theory; The swimming pool should take as the object of reference on mechanical analysis.
