摇撸式划水是花样游泳运动员利用动作升力的原理,使身体保持平衡的基础技术。对于竞技游泳来说(自由泳,仰泳,蝶泳和蛙泳),最重要的力是推进力,即利用手掌和手臂向后划水所产生的推进力,这个推进力是由正确的身体位置在一个推进平面内产生的。然而,由于游泳技术结构的三维本质,在每一种泳姿中,当手掌和手臂在驱动层面移动时,总会有一些对角线(横截面或纵截面)的点存在。
Swinging paddling is the basic technique by which synchronized swimmers use motion lift to keep the body in balance. For competitive swimming (freestyle, backstroke, butterfly stroke and breaststroke), the most important force is the propulsion, which is the propulsive force generated by the backstroke of the palm and arm. This propulsion is determined by the correct position of the body in a propulsion Plane generated. However, due to the three-dimensional nature of the swimming technique structure, there are always some diagonal points (cross-section or longitudinal section) in each swimming posture as the palms and arms move on the driving level.
