Increased exercise stroke volume

WebStroke volume is the major determinant of peak exercise capacity, and although this may be determined in part by increased ejection fraction, our data demonstrate that increased diastolic filling is the most important determinant of stroke volume augmentation and hence peak exercise capacity. WebAt the same time, increase in the sympathetic during activity during exercise will increase the heart rate and stroke volume increases the SBP. Though sympathetic activity has vaso-constriction ...
