Abstract

From a population of 20 healthy male volunteers, half performed constant speed, incremental load maximal aerobic capacity (\(\dot V_{O_2 \max } \)) tests on a motor-driven treadmill, while the other half performed similar\(\dot V_{O_2 \max } \) tests on a bicycle ergometer. The two groups, matched for size and age, showed no significant differences in\(\dot V_{O_2 \max } \), maximum heart rate, or in post-exercise (4 min) peripheral venous blood concentrations of lactate or pyruvate. However, post-exercise peripheral venous blood ammonia levels were significantly higher in the group tested on the bicycle ergometer than in the treadmill group.
