我们通常把蝶泳踢腿称作海豚泳。强调腿和脚有节奏的律动,有身体的中心发力。踢腿包括躯干,腿和脚的动作。放松的踝关节是高效的海豚踢的关键,让泳者报纸(笔误:可能是保持.老水耗子)平衡并给予发力点。必须保持连续的踢腿使得身体在水面保持正确的姿势,臀部接近水面。
(We often refer the butterfly kick as the body dolphin. To emphasize rhythmic action of the legs and feet, find the origin in the body's core. Kicking involves the torso as well as the legs and feet. Effective dolphin kicking is done with relaxed ankles which pull the water and provide a point of balance and leverage for the swimmer. The continuous kicking action must be maintained so that the body remains correctly postion on the surface of the water with hips near the surface. )
