[Observation on changes of heart rate and energy metabolic rate and their regression under upper and lower limb exercise].

Energy metabolic rate and heart rate were observed in 8 healthy young men during exercise on a bicycle ergometer. The results showed that there is a linear relationship between heart rate and metabolic rate during both upper and lower exercise, only that the metabolic rate is higher during upper limb exercise than during lower limb exercise under the same work load. It suggests that work efficiency may be influenced by mode of exercise.
