从专业条件来看,一位优秀的舞蹈演员,不仅要有较好的艺术素质,同时还应兼备美的线条,适宜的体重,所谓体态轻盈、翩翩起舞,敏捷灵活、矫健如燕。舞蹈是视觉的时空艺术。舞蹈以人体自身为工具,把人体动作作为表现手段,通过巧妙的变换与组合,以各种姿态构成舞蹈艺术形象。而各种动作、技术、技巧,均是在克服自身体重及其外界阻力的情况下才能完成,也就是说,身体愈重,做的“功”就愈多。“功”是一个物理学概念。功=力×距离(沿着力的方向移动的距离)。假如人的体重为G,以跳跃时身体重心升高的高度为h,那末,人所做的“功”就等于G乘以h,即W=G×h,如此看来,两个演员完成同样高度的跳跃动作,“胖”的比“瘦”的付
From the professional conditions, an outstanding dancer, not only have better artistic quality, but also should have the beauty of lines, suitable weight, the so-called light body, dancing, agile and flexible, vigorous and swift. Dance is a visual arts of time and space. Dance to the human body as a tool, the human movement as a means of expression, through clever transformation and combination of various poses to form the dance art image. And all kinds of movements, techniques and techniques are all accomplished under the condition of overcoming their own weight and resistance from outside. That is to say, the heavier the body is, the more “power” to do. “Gong” is a concept of physics. Power = force × distance (distance in the direction of force). If the weight of a person is G and the height of the center of gravity of a body when jumping is h, then the “work” done by a person is equal to G multiplied by h, ie W = G × h, so that the two actors complete The same height of the jump action, “fat” than the “thin” pay
