We investigated the oxygen uptake ( VO(2)) response to exhaustive square wave exercise of approximately 2, 5 and 8 min duration in cycling and running. Nine males completed a ramp test and three square wave tests on a motorised treadmill and the same four tests on a cycle ergometer, throughout which gas exchange was assessed (Douglas bag method). The peak VO(2) from the ramp test was higher for running than for cycling [mean (SD): 58.4 (2.8) vs. 55.9 (3.7); P=0.04]. However VO(2max) (defined as the highest VO(2) achieved in any of the four tests) did not differ between running and cycling [60.0 (2.9) vs. 58.5 (3.3); P=0.15]. The peak VO(2) was similar ( P>0.1) for the 5 and 8 min square wave tests [98.5 (1.8) and 99.2 (2.3) % VO(2max) for running; 97.0 (4.2) and 97.5 (2.0) % VO(2max) for cycling] but lower ( P
