有氧運動（Aerobic exercise）的核心在於藉由重複性、節律性的全身大肌肉群活動，增加氧氣消耗，從而改善心肺耐力與代謝功能。持續性運動能提升心搏量，降低靜止心率，並改善血管彈性，是預防冠狀動脈疾病（CAD）的基石。快走、游泳與騎腳踏車均符合此定義，能維持在目標心率範圍內且具備良好的持續性。
The core of aerobic exercise is to increase oxygen consumption through repetitive, rhythmic activity of large muscle groups throughout the body, thereby improving cardiopulmonary endurance and metabolic function. Sustained activity increases stroke volume, lowers resting heart rate, and improves vascular elasticity, and is a cornerstone for preventing coronary artery disease (CAD). Brisk walking, swimming, and cycling all meet this definition, can be sustained continuously, and keep the client within the target heart rate range.
