How do cardiac output, stroke volume, and cardiovascular pressures change from rest to exercise in healthy subjects?
In healthy subjects undergoing recumbent exercise, cardiac output increases linearly with oxygen uptake, while stroke volume exhibits only a slight initial increase before returning to baseline at higher workloads.
Holmgren et al. (1960) studied this question.
