The question regarding oxygen uptake kinetics centers on the rate-limiting step. This study was designed to observe the oxygen uptake response that occurs between a crossover of modes of priming exercises. Participants completed three exercise trials. Trial 1 involved cycling from rest to a target workload, Triat 2 entailed cycling from rest to light and then to the target workload, and Trial 3 was from rest to stepping followed by cycling at the target workload. Transitions from rest had similar half-time (1/2 t) values. Transitions that occurred after a priming exercise produced longer 1/2 t to steady state regardless of the mode of exercise: cycling from low to target workload =62 seconds, cycling after stepping =76 seconds. This data suggests that when oxygen uptake kinetics is concerned, exercise transitions from rest are more efficient than transitions from a warmed up state regardless of the mode of priming exercise.
