Aerobic exercise is a core element of fitness that focuses on improving cardiovascular endurance and respiratory efficiency. Activities such as running, erotic, cycling, swimming, and brisk walking elevate heart rate over sustained periods, strengthening the heart muscle and enhancing oxygen utilization.
Regular aerobic exercise reduces resting heart rate and blood pressure, lowering the risk of hypertension and coronary artery disease. It also improves cholesterol balance by increasing high-density lipoprotein (HDL) and reducing low-density lipoprotein (LDL), thereby protecting arterial health.
In addition, aerobic training increases lung capacity and stamina, allowing individuals to perform daily tasks with reduced fatigue. As a result, aerobic exercise is widely recommended as a primary preventive strategy against cardiovascular disorders.
