摘要:The purpose of this study was to find out the limiting factors of endurance owing to the aerobic capacity. The heart rate, respiration rate, pulmonary ventilation and oxygen intake were measured during and after the all-out running on the treadmill with 8.6% slope. And the oxygen removal and oxygen pulse were calculated. The tidal volume of ventilation, oxygen removal and oxygen pulse were found to be decreased significantly at the point of all-out. It was supposed from these results that the decrease in efficiency of respiratory function might be one of the limiting factors to the endurance. How. ever, it must be revealed whether this decrease of efficiency in the respiratory function might be caused the dropped cardiac output or the disturbed diffusion of the oxygen in thn lung.
