仰泳,即身体仰卧在水面上游进。由于人体本身具有浮力,只要在水中全身放松平卧,脸部露出水面,便于呼吸,腿部和手臂稍加动作,就可以浮于水面上游进。只要姿势正确,动作协调,是比较容易学会的。但如何才能使学生在较短的时间内掌握仰泳腿部技术,使其尽快学会仰泳,我个人认为在学习中抓住仰泳腿部的关键环节,是非常重要的。 对初学者来说,能否平稳地仰卧漂浮于水面,是一个关键环节。从技 Backstroke, the body supine swim on the water. As the body itself has buoyancy, as long as the body relaxed and supine in the water, face exposed surface, easy to breathe, legs and arms a little action, you can float on the water upstream. As long as the correct posture, coordination of movements, is relatively easy to learn. But how can we enable our students to master the backstroke technique in a relatively short period of time so that they can learn backstroke as soon as possible? I personally think it is very important to grasp the key links of the backstroke leg during my studies. For beginners, it is a key link to be able to float on the water smoothly. From technology
