鉴于当前世界竞技体育项目的高速发展,为了更好的适应新形势变化,针对表现难美性项群中自由体操、单跳、蹦床、跳水和空中技巧5个项目中,身体动作的主因子“空中身体翻转动作”进行分析研究,目的是通过该研究,能够对项目间的相互借鉴、以及项目技术的相互支撑起到一定的帮助作用,并对项目的发展具有一定的实际意义。通过文献资料法、访谈法、录像分析法等研究方法进行系统分析,得到以下结论:1)空中身体翻转动作是运动员身体在空中围绕运动轴完成单向或多向翻腾和转动的技术动作,是5个表现难美性项目的核心技术。2)依时间的递进进行观察和描述,一个完整的身体翻转动作包含起动加速、起跳、空中翻转、落停4个相互连接的技术环节。3)自由体操和单跳的空中身体翻转动作常以多式样的空中身体翻腾转体难度动作直接连接另一个空中身体翻转难度动作。4)空中身体翻转技术动作的递进式发展历程可分为5个发展阶段:单一翻腾阶段;单一的翻腾或旋转阶段;复合翻转阶段;多翻多转及“叠加”翻转阶段和自由体操与单跳进入突出平面挂串连接阶段。5)发展表现难美性项群空中身体翻转动作的对策设计为:及时研究、积极适应国际评分规则的变化,科学把握空中身体翻转动作的有序性发展规律,主动发掘空中身体翻转技术动作的创新途径。
In view of the rapid development of the current world competitive sports, in order to better adapt to the new situation changes, for the performance of the difficult items in the group of free exercise, single jump, trampoline, diving and aerial skills five projects, the main factor of body movement The purpose of this research is to help the project to learn from each other and to provide mutual supportiveness to the project technology, which will be of some practical significance for the development of the project. Through literature review, interview and video analysis, the following conclusions can be drawn: 1) Aerial body turning action is the technical action of the body of athlete completing one-way or multi-direction tumbling and turning in the air around the axis of motion. 5 performance of the core technology of the project. 2) Progressive observation and description in terms of time, a complete body flip action includes start-up acceleration, take-off, aerial reversal, landing 4 interconnected technical aspects. 3) Free exercise and single-jump air body flip action often multi-style air body tumbling swivel difficulty action directly connected to another aerial body flip difficult action. 4) The progressive development of the air body turning technology movement can be divided into five stages of development: a single tumbling stage, a single tumbling or rotating stage, a compound tumbling stage, a multi-turn and “overlay ” flip stage and freedom Gymnastics and single jump into the prominent plane hanging string connection stage. 5) The development of performance is difficult to beauty group air body flip actions countermeasures designed to: timely research, and actively adapt to changes in the international scoring rules, scientific grasp of the orderly development of air body flip action law, the initiative to explore the action of air body flip technology Innovative ways.
