Recently, much attention has been focused on the physical fitness of judoists, and various measurements are being made in order to grasp the actual condition and characteristics of physical fitness. General endurance which is an important factor of physical fitness has received early attention andmany reports have already been published conceming it, and the lack of general endurance of judoists has been pointed out. For example, Sasa et al. conducted treadmill studies on the maximal oxygen uptake, and Ikai et al. made bicycle ergometer investigations on the maximal oxygen uptake, stroke volume and pulmonary diffusion volume. Results of both studies indicate that the judoists were not at all superior to athletes of other sports or even to the ordinary people. Results of Ikai's studies on the respiratory and cardiovascular functions of Lusca, the Dutch Champion of the World Judo Tournament show that he was superior to the Japanese judoists in the parameters that were investigated. Studies by Sugimoto on the energy metabolism during the performance of the waza (technique), and also studies by Ikai on the pulse rate during the Randori (free exercise) both indicate that judo involves very intensive bodily movements. Moreover, recently the judo contest time is gradually being lengthened, which means that general endurance becomes all the more necessary. The purpose of the present study is to determine an efficient method of training to enhance general endurance; and in order to do so, endurance running and the most strenuous bodily movements in judo practice were selected as the means of training, and their respective effects were analyzed.
