Oxygen Uptake and Heart Rrte during Work on the Bicycle Ergometer with One and Both Legs

Abstract

Nine healthy young male subjects performed low level exercises (20, 40, 60 W) on bicycle ergometers with one leg and both legs. Their oxygen uptake (VO2) and heart rate were measured during one- and both-leg exercises. Both the V02 and the heart rate were significantly higher during one leg than during both legs at each work load. There was no difference in correlation between heart rate and V02 in cases of one leg and both legs exercises.
