Since the effects of endurance training appears in increase of aerobic threshold of maximum oxygen uptake, we studied the mechanism by using treadmill runs. Subjects were five healthy long distance runners (age; 21∿22yrs, body weight; 60.1±2.0kg, body height; 173.3±3.1cm, carreer; 9.0±2.5 years, maximum oxygen uptake; 70.1±3.7ml/kg/min). The heart rate, oxygen uptake and ventilation were measured at every 130m/min, 150m/min, 170m/min, 190m/min, 210m/min, and 230m/min runs and from these data physiological responses with increase of 20m/min running velocity were obtained. The oxygen uptake and CO_2 exctretion had a linear relationship to these running velocities. But the ventilation did not increase significantly from 130m/min to 170m/min runs and reversely heart rate significantly increased (p<0.05). From 190m/min to 230m/min runs, the heart rate and ventilation significantly increased (p<0.05,respectively). Moreover, the tidal volume and respiration rate did not show regulation on running velocities throughtout these running velocities. From these results cardiac output and diffusion capacity of long distance runners in submaximal exercise are superior to oxygen uptake in aerobic exercise and these results suggests that such training method cause increase of maximal oxygen uptake.
