Kicking Technique ( 打腿技术 )

This week’s Speedo Tip of the Week comes from Deb Whitney, USA Swimming’s physiology coordinator and holder of several school records at Dartmouth College. Whitney offers some advice on kicking technique.

怀特利的贴士

It is important for you to think about your kick and how it fits into the rest of your stroke.  If you look at the top American swimmers, you will notice that the number of kicks, strength of the kicks and kicking technique is different for each swimmer. Some swimmers kick with a six-beat kick in freestyle (six kicks for each stroke cycle), while others use a two-beat kick or a four-beat kick.  A six-beat kick raises the legs slightly higher in the water, and the energy needed to maintain this kick during training or racing is higher than for a four-beat or two-beat kick.  In the past, it was thought that distance swimmers should use a two or four-beat kick, while sprinters should use a six-beat kick.  We now realize that the type of kick a swimmer uses is only as important as how well it fits into and complements their stroke. As with everything, practicing your kick is very important. Kick in practice the way you want to kick in competition. I would recommend discussing your kicking technique with your coach to determine what works best for you. Good luck, and keep on kicking.
对大家来说，如何让打腿和后面的其他技术动作衔接完美是非常重要的！你可以参考美国的顶级游泳运动员，你将会发现他们打腿的数目、强度和技术各有不同。有些游泳运动员自由泳做6次打腿（一个完整的自由泳划手周期内作6次打腿），但有些运动员则作两次或者四次。六次打腿的运动员在水中抬腿的高度稍高，无论在训练中还是在比赛中，这种动作对于能量的要求都要高于两次或者四次打腿。过去，大家都认为长距离运动员应该采用两次或者四次打腿，而短距运动员则需要采用六次打腿。但目前，我们认为采用哪种打腿应该取决于运动员如何完整配合划手和打腿！在任何情况下，练习打腿都非常重要，试着象比赛中那样练习打腿！我建议你和你的教练商量，看哪种打腿方式最适合你。祝你好运，但，持续练习打腿吧！
