用科学新技术指导游泳姿势,选择水中运动力学的动作,从而提高游泳水平,是世界泳坛的新动向。○测定牵引张力在体育界,用生体力学和运动生理学分析结构和运动机能,以期提高运动水平的作法已普遍引起人们的关注。在游泳方面,电子学、生理学、营养学等领域的专家正在进行新的尝试,以使运动员的游泳姿势达到最理想的状态,并尽量延长运动员的运动寿命。日本东京工艺纺织大学副教授野村照夫开发了一种牵引张力测定装置,在游泳训练中发挥了作用。野村给一位女蝶泳运动员作了测试,他操纵电子计算机,显示屏上显示出上下波动很大的图形。野村说:“这表明,每次划水过程中都加进不必要的阻力。通过
It is the new trend of the world’s swimming pool to guide the swimming posture with new science and technology and select the action of underwater sports mechanics so as to improve the swimming level. ○ Determination of traction tension In sports, biomechanics and exercise physiology to analyze the structure and motor function, with a view to raising the level of exercise has been widely aroused people’s attention. In swimming, experts in the fields of electronics, physiology, nutrition and other fields are making new attempts to achieve the best swimmer’s swimming position and maximize the athlete’s life expectancy. Nomura, an associate professor at the Tokyo Institute of Technology and Textile, Tokyo, Japan, developed a traction tension measurement device that has played a role in swimming training. Nomura tested a female butterfly swimmer who manipulated a computer with a graphic showing up and down fluctuations. Nomura said: ”This shows that every time you draw water are added unnecessary resistance
