Posture-dependent stroke volume responses during exercise extend physiological models in healthy males; leaves open relevance to patients with cardiovascular disease.
How do cardiac output and systolic time intervals respond to supine versus upright exercise in healthy males?
Stroke volume increases significantly during upright but not supine exercise, while left ventricular ejection time falls shortly after exercise cessation regardless of stroke volume changes.
Miyamoto et al. (1983) studied this question.
