장거리 선수의 운동시 좌심실 형태에 관한 연구 = A Study on Left Ventricular Dimensions of Long Distance Runners during Exercise

다국어 초록 (Multilingual Abstract)

The purpose of this study was carried out to investigate changes of the left ventricular dimensions in long distance runners during exercise.
The subjects were eight male long distance runners(average age; 21 ±1.04 years, carreer; 7.4 ±2.11 years, height; 170.1 ±4.41cm, body weight; 59.2 ±3.27kg) and ten male non-athletes(average age; 23.2 ±1.16 years, height; 168.3 ±3.65cm, body weight; 61.4 ±3.41kg).
Left ventricular dimensions were measured by 2-dimension echocardiography at rest and during 8 min of semisupine, graded bicycle ergometer exercise(0.5kp and 1.0kp)
Left ventricular dimension was significantly hyperthrophy in long distance runners than non-athlets.
As for dimensions, left ventricular end-diastolic dimension(LVDD), left ventricular end-systolic posterior wall thickness(PWTS), interventricular septum thickness at end-systolic(STS) and amplitude of motion of posterior left ventricular endocardial echo(ENa) increased during exercise in long distance runners and non athletes.
Left ventricular end-systolic dimension(LVSD), left ventricular end-diastolic posterior wall thickness(PWTD), interventricular septum thickness at end-diastolic(STD) and ratio of wall thickness to internd radius(h/R) decreased during exercise in long distance runners and non-athletes.
