CO x arterio-venous difference 1 of 23 During exercise, oxygen demands increase by 13 x 2 of 23 Cardiac stroke volume increases during exercise by 1.5 x 3 of 23 Heart rate increases by 3 x 4 of 23 Arteriovenous difference increases by 3 x 5 of 23 What is cardiac output's relationship with work rate? Positive linear 6 of 23 Cardiac output increases from ... to ... 5 to 25l/min 7 of 23 Heart rate rises how with work rate? Linearly 8 of 23 What is a normal range to find max heart rate in? 180-200 9 of 23 How does stroke volume vary with work rate? Increases then decreases 10 of 23 What is not a reason that stroke volume increases with increased work rate? Reduced filling time 11 of 23 Almost all increase in stroke volume occurs at a ... low work rate 12 of 23 A 5 x increase in cardiac output can increase muscle blood flow by how much? 20 x 13 of 23 Where does vasoconstriction not occur? Muscles 14 of 23 The increase in arteriovenous difference is a result of? Decreased venous oxygen content 15 of 23 What is not a reason that O2 uptake in lungs and delivery to muscles might be limited? The long distance from lungs to muscles 16 of 23 Cardiac output can be increased by how much with an elite level resting heart rate? 7 x 17 of 23 Endurance training does what to blood volume? Increases 18 of 23 Plasma volume does what with endurance training? Increases 19 of 23 How does haemocrit change with endurance training?
