The purpose of this study was to examine whether ventilation kinetics are related to blood lactate level after 5 min in recovery after a sprint. Subjects performed two tests, one test consisting of one sprint with maximal effort and the other test consisting of five repeated sprints with time intervals of 6 min. The recovery period from the last sprint was 30 min. Oxygen uptake during recovery from one sprint was the same as that during recovery from five repeated sprints. Ventilation after 50 sec in recovery after one sprint was the same as that in recovery after five repeated sprints despite the significantly higher blood lactate levels during recovery from five repeated sprints than that from a single sprint. There was an exponential relationship between ventilation and blood lactate after 5 min in recovery. The curve shifted to the right in the case of five repeated sprints. End tidal CO2 pressure after one sprint was higher than that after five repeated sprints during recovery. From these results, it seems that ventilation control related to blood lactate level is modified by end tidal CO2 pressure.
