摘要

本文目的在探討運動員經過長期訓練後心臟的適應現象，長期運動訓練介入致使心臟肥大、左心室肥大或運動員心臟。目前已有許多研究探討耐力型及阻力型運動訓練對左心室的適應效果比較，特別是探討舉重與長跑選手的差異性最多，這一類研究大部份採用橫斷性的研究，耐力型運動員心臟以心室腔擴大且伴隨心室壁增厚，而阻力型運動員心臟以心室壁增厚為主，心室腔並沒有顯著改變，而運動訓練後對安靜狀態下左心室功能的影響則較為分歧。最近有些研究探討長期運動訓練後右心室的適應效果，或能使用配合MRI的運動器材，如固定臥式腳踏車，收集運動進行中的左、右心室構造和功能等數據，更有助於了解運動員心臟的適應效果。

The purpose of this study was to review the adaptation of heart in athletes after long-term exercise training. Exercise training intervention was presumed to myocardiac hypertrophy, left ventricular hypertrophy or athlete's heart. Studies showed that cardiac adaptations may differ according to the type of sports such as to compare the difference between weight lifting and long distance runners (cross-sectional design). Endurance-trained athletes are presumed to demonstrate eccentric left ventricular hypertrophy (increased left ventricular wall thickness and left ventricular chamber size). Athletes involved in mainly static or isometric exercise (eg, weightlifting) develop predominantly increased left ventricular wall thickness with unchanged left ventricular chamber size. In present, some longitudinal study will examine the adaptation of the ventricular and collect the structure and function of ventricular during maximal exercise by using a MRI-compatible bicycle ergometer. It's useful to realize the adaptation of athlete's heart
