Development of Sprint Training Machine for sprint running

1)研制新型短跑训练机。通过对世界顶尖运动员的生物力学研究发现，日本短跑运动员要获得双腿的较快动作，必须进行腿筋和臀肌这两条髋关节伸展肌的肌肉训练。2)本研究的目的是在类似短跑的动作中进行肌肉训练。3)本研究在自行车运动的基础上发展出理想的腿部运动轨迹。4)新研制的机器命名为“短跑训练机”。新机器的特点是：基本结构：1)活动底座(左右腿配对)，有曲柄、臂和踏板。2)电机和变速器。3)电动刹车。4)扶手：操作员使用扶手站在踏板上。移动底座是以一定的速度在50-100 cm的范围内以一定的速度交替来回移动，操作者必须在移动的底座上保持双腿站立的位置进行自行车运动。电动制动器在运动的踢脚阶段倾斜。5)该机需要获得日本和国外的专利。

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.
