竞速游泳是争分夺秒的项目,在今天的实际竞赛中,百分之一秒就足以判定夺标先后.分析一下竞赛成绩的构成,不外出发、转身和途中配合游几部分,而出发和转身的时间在决定竞赛成绩上有着举足轻重的作用。科学地判定出发和转身的时间要兼顾技术和距离两个因素,这个距离还应考虑项目的差异。本文提出的测定距离正是如此。我们认为这个测定距离是可取的,而我国的测定距离,如在“1984年上海国际游泳邀请赛调研报告”一文中采用的是值得商榷的,因为距离过短就不能包括出发、转身动作;距离过长又包括了途中配合游的时间。都造成测定的失真.采用统一的、科学的测定出发、转身距离,不但可以准确地测定出发、转身时间,而且便于分析比较。盲目地、无根据地说某一运动员游得慢,不如准确地指出“慢”在哪里,这就需要科学的测量,给运动员提供正确的反馈信息。提高游泳成绩首先来源于对游泳技术某一环节的重要性的认识。
Race swimming is a race against time, in today’s actual race, one hundredth of a second is enough to determine the winning hand .Analysis of the composition of the competition results, but starting, turning around and on the way with a tour of several parts, and starting and turning Time plays a decisive role in determining competition performance. Scientifically determine the departure and turn around time to take into account both technology and distance factors, this distance should also consider the project differences. The measurement distance proposed in this paper is exactly the same. We think this determination of distance is desirable, and our measurement distance, as used in the “1984 Shanghai International Invitational Tournament Research Report,” a paper is open to question, because the distance is too short can not include starting and turning movements; distance Long also includes the way with the travel time. Have caused the determination of distortion.Using a unified, scientific determination of departure, turning distance, not only can accurately determine the departure, turn around time, but also easy to analyze and compare. Blindly, unfounded to say an athlete swim slowly, it is better to point out exactly where “slow”, which requires scientific measurement, to provide athletes with the correct feedback. First of all, to improve swimming performance from the understanding of the importance of some aspects of swimming technology.
