Why the study?
Does upright versus supine posture during exercise at varying temperatures affect skin blood flow and cardiac stroke volume?
Does upright versus supine posture during exercise at varying temperatures affect skin blood flow and cardiac stroke volume?
During exercise in the heat, upright posture reduces stroke volume and skin blood flow compared to supine posture, likely due to blood pooling and subsequent baroreflex activation.
No takes yet. Share an insight, caveat, or question.
Posture may influence cardiovascular strain during heat stress; leaves open whether targeted positioning improves safety in at-risk patients.
Roberts et al. (1980) studied this question.
