Abstract: The concept of VO2max has been a defining paradigm in exercise physiology for >75 years. Within the last decade, this concept has been both challenged and defended. The purpose of this study was to test the concept of VO2max by comparing VO2 during a second exercise bout following a preliminary maximal effort exercise bout. The study had two parts. In Study #1, physically active non-athletes performed incremental cycle exercise. After 1-min recovery, a second bout was performed at a higher power output. In Study #2, competitive runners performed incremental treadmill exercise and, after 3-min recovery, a second bout at a higher speed. In Study #1 the highest VO2 (bout 1 vs. bout 2) was not significantly different (3.95 + 0.75 vs. 4.06 + 0.75 l min-1). Maximal heart rate was not different (179 + 14 vs. 180 + 13 bpm) although maximal VE was higher in the second bout (141 + 36 vs. 151 + 34 l min -1). In Study #2 the highest VO2 (bout 1 vs. bout 2) was not significantly different (4.09 + 0.97 vs. 4.03 + 1.16 l min -1), nor was maximal heart rate (184 + 6 vs. 181 + 10 bpm) or maximal VE (126 + 29 vs. 126 + 34 l min -1). The results support the concept that the highest VO2 during a maximal incremental exercise bout is unlikely to change during a subsequent exercise bout,
