It has recently been reported that blood and muscle lactate increased exponentially during incremental exercise, casting some doubt upon the concept of 'anaerobic threshold'. To gain further insight into this controversy, we examined the relationships between minute ventilation (VE), time and oxygen uptake (VO2) in normal subjects during incremental exercise. During exercise, the relationship of VE to either time of exercise or to VO2 appeared curvilinear; VE was reliably described as an exponential function (y = axb + c) of both time of exercise (r2 = 0.96) and VO2 (r2 = 0.92). We also compared variables from 30-second incremental tests with variables obtained from quasi-steady-state incremental tests using cycle and treadmill ergometry. With the exception of heart rate, variables measured at maximum exercise were similar during short-duration and quasi-steady-state incremental tests. These data support the ideas that: there is no abrupt change in metabolism and oxygen availability during progressive exercise, and results of rapid incremental and quasi-steady-state exercise tests are generally comparable in normal individuals.
