In order to clarify the kinetics of excess CO2 output during and after intensive exercise, six male subjects were each instructed to perform 40-, 60- and 80-s cycle ergometer exercises (282 +/- 9 W, 90 rpm). Ventilation and gas exchange parameters were recorded breath-by-breath, and lactate concentration (La) was repeatedly measured with blood samples from a finger tip. The increase in La from the resting value to peak value and the duration of exercise showed a significant linear relationship (r = 0.91, p
