Five healthy male subjects were tested for oxygen uptake and heart rate during arm, leg, and combined arm and leg exercise on cycle ergometers. The maximal aerobic power (VO_2max) of arm and combined arm and leg exercises were about 60% and 115% of leg exercise, respectively. For a given work load, higher oxygen uptake and heart rate were observed during arm exercise. While the oxygen uptake and heart rate relationship was essentially rectilinear up to high submaximal work loads when running, this relationship was curvilinear in arm cranking. For a given oxygen uptake, higher heart rate was obtained during arm exercise than leg exercise. When comparing combined arm and leg exercise to arm or leg exercise, lower heart rate was observed at a given oxygen uptake. This difference was more significant when the arm work intensity was 20% of the total rate of work. It was suggested that the difference in heart rate for a given oxygen uptake between arm, leg, and combined arm and leg exercise was due to a difference of stroke volume.
