| Abstract: | This study examines whether blood lactate level affects oxygen uptake at the offset of exercise (recovery ‡O2) in middle.intensity exercise. Work rates in the exercise were constants at 60, 100, 140, 180 and 220 watts, respectively. Recovery ‡O2 was approximated by a single or double exponential function to determine whether the kinetics of recovery ‡O2 has only a fast phase or fast and slow phases. Blood lactate was determined at rest and at 3 min during recovery. One phase was observed below a blood lactate level of 3 mM (low-intensity exercise), one or two phases observed at a blood lactate level between 3 and 6 mM (middle-intensity exercise) and only two phases were observed above 6 mM (high-intensity exercise). Thus, exercise intensities were divided into three levels. ‡O2 at 3 min during recovery was related to blood lactate at 3 min during recovery. The regression line obtained between them at 3 min during recovery ranged from the resting values of ‡O2 and blood lactate to the highest value in high exercise intensity. We concluded that blood lactate affects recovery ‡O2 even when it cannot be mathematically separated into two phases. |
