摘要：Various attempts to record human locomotion have been tried since the end of the 19th century. The most fundamental attempt of them is to record the time during which the foot contacts with the ground and the force which is exerted on the ground by the foot. In the present study, a new instrument was devised in order to record both items mentioned above It consists of small semi conductive straingauges which are fixed in the parts of the toe and the heel of the shoe and from them electrical changes are led to an oscillograph through a Wheaston's bridge. Using this instrument, the motion of the foot in walking and running on the motor-driven treadmill at various speed was recorded. Based on these records, an analysis of the relationship between the length of the time or the pressure of the sole in connect and speed of walking and running became possible. In addition to the recordings of the foot pressure, the electrogoniogram at the knee joint and EMG of the leg muscles were simultaneously put on records. On the basis of the data the movements of the legs in walking and running could be more accurately analyzed.
