WebDuring submaximal steady state exercise, HR and total peripheral resistance are higher, while stroke volume [SV (ml)] and cardiac output [Q (L/min)] are lower in children at a given rate of work. At maximal exercise intensities HR is higher while SV and Q are lower in children than adults. WebThe relationships between exercise intensity and 1) stroke volume, 2) end-systolic volume, and 3) end-diastolic volume are different when exercise is per-formed in the supine posture versus exercise in the upright posture, as illustrated in Fig. 3.
