To reveal the limiting factors in endurance running on the treadmill was the main interest in this study. An excellent Japanese long distance runner who later got the third place at the Olympic marathon race in 1964, K. Tsuburaya, 23 served as the subject. The all-out running time, heart rate, respiratory rate, pulmonary ventilation and oxygen intake were measured when he ran at the two different speeds, 260m/min. and 240m/min., on the treadmill with 8.6% slope. From these measurements tidal volume, oxygen removal and oxygen pulse were calculated. The all-out running time of this subject was found to be 6 minutes 58 seconds at the speed of 260m/min. and 21 minutes 09 seconds at the speed of 240m/min.. The heart rate and respiratory rate were increased during running toward the point of "all-out". It is worthy to note that the respiratory rate showed an abrupt increase near the point of exhaustion accompanied by decrease of tidal volume. The oxygen removal, the ratio of oxygen intake to pulmonary ventilation, was also decreased gradually during running unit it decreased to about 35 near the point of "all-out". It was supported from these results that the decrease of efficiency of respiratory function might play a big role to limit the endurance for running. It should be, in the next step, decided whether this decay of efficiency of the respiration would be caused by decreased cardiac output or uneven distribution of gas in the lung.
