The purpose of this study was to determine whether high intensity, long-term aerobic training
causes the left ventricle to develop different mechanisms for increasing cardiac output …

This investigation examines the hypothesis that athletes increase stroke volume with
submaximal exercise through an augmentation of left ventricular (LV) end-diastolic volume …

To determine the changes in left ventricular volume and their time course during exercise we
studied 30 runners. Left ventricular end-diastolic and end-systolic volumes were measured …

Two-dimensional echocardiography was used to determine the responses of left ventricular
volumes, ejection fraction and segmental left ventricular motion to supine dynamic exercise …

To define the effects of gender on stroke volume control during upright exercise in normal
subjects, we examined central hemodynamics in 34 men and 27 women during staged …

Whether exercise-induced increases in left ventricular mass can alter left ventricular diastolic
function was evaluated by measuring transmitral flow velocities at rest by Doppler …

To assess left ventricular structure and function at rest and during exercise in endurance
athletes, 10 elite marathon runners, aged 28 to 37 years, and 10 matched nonathletes were …

Adaptive cardiac responses to isotonic training were studied with echocardiographic
measurement of cardiac dimensions and function in 20 endurance runners whose maximal …

To determine the role of preload in maintaining the enhanced stroke volume of upright
exercise-trained endurance athletes after deconditioning, six highly trained subjects …

This study compares the left ventricular performance of chronically conditioned pentathletes
(N= 10) with less-conditioned subjects (N= 10) during dynamic upright exercise. The …
