Left atrial (LA) and right atrial (RA) volumes were calculated from two-dimensional echocardiography (2D echo) in 54 normal volunteers, of whom 23 were nonathletic men and 25 nonathletic women; 6 additional men had a history of athletic training. Ages ranged from 20 to 66 years (average nonathletic group, 38 years; athletic men, 28 years). The LA volume was measured by single-plane area-length. Echocardiographic examinations were performed in 60 professional bicyclists and control subjects to determine the effects of exercise on left ventricular hypertrophy and function. The athletes were separated by age into three groups: group 1 (n = 14), years; group 2 (n = 17), years; and group 3 (n = 29), years.
Normalizing left ventricular mass by body mass further equalized the 2 groups (P=). In addition, there was no difference between groups in the ratio of wall thickness to lumen or for any echocardiographic measure of systolic or diastolic function, including the aortic root area used to calculate arterial compliance and the diameter of the. IN PATIENTS WITH acromegaly and preserved left ventricular (LV) systolic function at rest, ejection fraction response during physical exercise may be abnormal (1–3).Systolic dysfunction during exercise has been found in patients with long-standing acromegaly as well as in those with early onset GH excess (2, 3).The mechanisms responsible for the abnormal ejection fraction response during.
An accurte echocardiographic (E) method for determination of left ventricular mass (LVM) was derived from systematic analysis of the relationship between the antemortem left ventricular echogram and postmortem anatomic LVM in 34 adults with a wide range of anatomic LVM ( g). The echocardiographic left ventricular examination reveals an enlarged chamber (end-diastolic dimension, cm/sq m) with marked mechanical alternans. The left ventricular end-diastolic dimension is constant from beat to beat, and the end-systolic dimension varies from .

Although meta‐analysis of studies involving long‐distance runners revealed an increased left ventricular internal diameter and an increase in septal and posterior wall thickness relative to population norms, the majority of athletes in these studies manifested echocardiographic characteristics still within the normal range.

Background A considerable body of echocardiographic studies has described how athletic training induces morphological adaptation of the left ventricle in male endurance athletes, but only a few studies have described left ventricular adaptation in female endurance athletes.
In contrast to changes in the left ventricle far less attention has been directed towards right ventricular changes due Cited by: Concentric adaptation of the left ventricle in response to controlled upper body exercise training Article (PDF Available) in Journal of Applied Physiology 94(2) February with 29 Reads.

By subtracting 20% to the measured value, ovine end diastolic diameter approaches closely to the upper. Abstract. The objective of the study was to investigate whether a blood pressure increase during static exercises might affect the left ventricular function and whether a possible pressure overload might decrease cardio-respiratory adaptation to aerobic exercise in power lifting athletes.

The normal reference data are very limited in this population. We report left ventricular end-diastolic diameter (LVEDD) and interventricular septal diameter (IVSD) echocardiogram findings in college football athletes. We sought to establish echocardiographic reference intervals for MAPSE, TDI and 2DSTE measures of LV longitudinal function in healthy adult ESS.
Additionally, we examined intraobserver measurement repeatability, the effects of annular position and whether these variables were related to age, body weight, left ventricular length or heart rate.Echocardiographic Evaluation of Right Ventricular Function M.
