“Uchi-mata” difference was discovered by using available motion pictures.The motion pictures were disassembled into frame data called AVI,which is a file format for storing audio and video information developed by Microsoft Corp.The motions performed by participants while using Judo standin “ Uchimata” were analyzed using a software system based on “Open CV”,which is an open source library for computer vision and image processing developed by Intel Corp.The positions of parts of the body were indicated manually on to the AVI pictures based on the “frame by frame playback” technique, then put into a computer. The compensation of pixel values to the real space size was performed by using the known length of the“ tatami” in the AVI picture.By repeating these,the positions of the body were traced corresponding to the frame rate.The compensated positional data of the body was gathered and then disassembled into x direction-time data and y direction-time data to calculate velocity. In this manner,the velocity of the specified body parts of the thrown opponent were calculated.The subjects selected were two leading Judo men.When he threw his opponent down,his motion of his stand technique of“ Uchi-mata” was analyzed.This is a case study of motion analysis of Judo using available motion pictures.We have given an example of an analysis method for Judo from an engineering point of view.

【Abstract】 The aims of the present study were to investigate characteristics of variations in substrate metabolism with time during prolonged exercise in trained women and to examine the optimal exercise intensity and duration of endurance training in women as exercise prescription. Expired gas was measured in ten trained women who performed 120-min treadmill walking and running at several exercise intensities. Substrate oxidation was computed by substituting determined oxygen uptake and carbon-dioxide output into stoichiometric equations. A constant level of energy expenditure was needed during prolonged exercise at the same intensity, but the enhancement of lipid metabolism with exercise duration led to an increase in fat-derived energy provision and a decrease in the dependency ratio of carbohydrate-derived energy to required energy. Lipid metabolism during low-intensity exercise wasconstantly-enhanced with duration whereas that during moderate- and high-intensity exercise was slowly increased beyond 60 min after initiating exercise and the proportion of fat-derived energy to required energy decreased with increasing exercise intensity. These findings suggest that women inendurance training should continue low-intensity exercise for as long time as possible and that they should select the moderate-intensity to sustain exercise beyond 60 min in order to increase the total volume of energy expenditure.
