Development of machine training system for strengthn muscles of inner body

本研究旨在开发一种新型的训练体系，以增强躯干内侧肌肉的力量。为该训练系统研制了8种不同类型的训练机。类型1：滑床髋关节伸屈训练机。受试者将腿悬在Leber手臂上，以仰卧的姿势，伸展和弯曲髋关节。类型2：腿部和臀部摆动机器。受试者单腿站立，同时摆动他的腿和同侧的臀部。机器的摆臂被卡住在滑动箱上，滑箱在轨道上移动，与摆臂的旋转运动同步。类型3：简单的腿部和臀部摆动机器。类型4：电动助力扭身机。该机的转台和手柄利用电力向旋转方向旋转。受试者站在转台上，双手握住手柄，在机器旋转运动的引导下扭转全身。类型5：手臂和腿部测功器。受试者以站立姿势同时旋转手臂测功器和腿部测功器。这台机器被命名为动物步行机。腿部测功器的踏板运动轨迹为椭圆形。类型6：低体能人群步行训练机。受试者用无座椅站立的踏板，就像自行车上的站立踏板。在机器中，踏板臂的旋转轴在步长范围内靠电力往复向前和向后移动。类型7：半圆柱体底部的训练器，通过两腿左右张开或前后张开的姿势握住身体来加强躯干下部的力量。类型8：转圈训练机，受试者在其上旋转双腿转弯动作的转圈-立式

In this study, it was intended to develop new type of training system to strengthn inner muscles of torso like illopsoas. Eight different type of training machines were developed for the training system.Type 1 : Hip Extension & Flexion Machine with Sliding Bed. The subject hangs his leg on a leber arm with a supine position, and extend and flex hip joint. Type 2 : Leg & Hip Swing Motin Machine. The subject stand on one leg and swing his leg and hip of the same side,reciprocaly. A swing-arm of machine was stalled on the sliding box which move on a rail synchronizing to a rotatory movement of a swing-arm. Type 3 : The simple type of Leg & Hip Swing Motin Machine. Type 4 : The Body Twist Machine with Power Assisted. The turn stand and handle of the machine move to the revarse rotatory direction with electlical power. The subject stand on a turn stand and hold a handle with both hands, and twist his whole body with the guide on rotatory movement of the machine. Type 5 : The Arm and Leg ergometer. The subject rotate arm ergometer and leg ergometer simultaneously with standing position. The machine named Animal Walk Machine. The orbit of pedal movement for leg ergometer was oval. Type 6 : Walking Motion Training Machine for low fitness persons. The subject work pedal with standing position without seat, like standing pedaling on bicycle. In the machine, the axis of rotation of the pedal arm move to forward and backward reciprocally by electric power within the distance of one's stride length. Type 7 : Training Device Shaped Bottom of Half Cylinder which strengthen lower part of torso by holding body with posture of two legs open right and left or front and back direction. Type 8 : Rotatory Circle Training Machine on which the subject rotate circle-stand with both legs like cornering motion of skating
