上两期分别介绍了年龄组常用的爬泳和仰泳技术训练方法,这期我们来介绍年龄组常用的蛙泳技术训练方法,同样大致可分为三类:腿部技术、手臂技术和完整配合技术。一、蛙泳腿技术训练方法技术要点:蛙泳的腿部动作不仅起到保持身体平衡的作用,还可以产生较大的推进力。腿部动作可分为收腿、外翻和蹬夹、滑行几个紧密相连的完整动作。收腿时屈膝,脚后跟沿水面慢慢向臀部靠近,收腿结束时,两膝与
On the two were introduced in the age group common practice of stroke and backstroke techniques, this time we introduce the age group commonly used breaststroke training methods, the same can be roughly divided into three categories: leg technology, arm technology and complete with the technology . First, the breaststroke technique training methods Technical points: Breaststroke leg action not only played a role in maintaining body balance, but also can produce greater propulsion. Leg movements can be divided into the leg, valgus and pedal clip, glide a few closely linked to the full action. Legs knees, slowly along the water to the hips near the heel, closing legs, knees and
