Development of Sprint Training Machine for sprint running

1)本研究旨在研制新型短跑训练机。它是从世界顶级运动员的生物力学研究中发现的，认为日本短跑运动员要使两条腿的运动速度更快，就必须进行髋关节伸肌--腘绳肌和臀大肌的肌肉训练; 2）本研究的目的是在短跑的类似动作中进行肌肉训练; 3）本研究以自行车运动为基础，通过自行车中心部位的前后运动与蹬车运动相结合的方式，开发出理想的腿部运动轨迹。4）新研制的机器被命名为“短跑训练机”。新机器的特点如下：基本结构：1）移动底座（左右腿成对设置），有曲柄、臂和踏板。2)电动机和变速器。3)电动刹车4）扶手。操作员使用扶手站在踏板上。移动底座在50- 100 cm范围内以一定速度连续电动前后交替移动，操作者双腿在移动底座上保持站立姿势进行循环运动。电动制动器在运动的反冲阶段工作。5）本机需申请日本和国外专利。

1) Development of new type of training machine for sprint running was purposed in this study. It was found from biomechanical research for world top athletes, that muscular training of hamstrings and m.gluteus maxi.mus.which are extensor of hip joint was necessary for Japanese sprinters to make faster movement of both legs.2) It was intended in the study that muscle training is carried out in the similar movement of sprint running.3) In this study on ideal locus of leg movement was development in the combination of cycling movement like as becycle and back and forth movement of the center part of cycling.4) Newly developed machine was named 「Sprint Training Machine」. Characteristics of new machine are as follows :Basic structure : 1) moving base (pair set for right and left leg), having crank, arm and pedal. 2) Electric motor and transmission. 3) Electric Brake. 4)Handrail.Operator stand on the pedals using a handrails. Moving base is moved electrically back and forth alternately at a certain speed in the range of 50- 100cm, successively.Operator has to make cycling movement with both legs holding a standing position on the moving bace. Electric brake poerate in the kicking phase of movement.5) Patent of Japan and abroad was required for this machine.
