Aerobic exercise, also known as cardio, is a type of physical activity that involves sustained movement, elevating your heart rate and breathing for an extended period. Common examples include running, swimming, cycling, and dancing. This type of exercise is typically performed at a moderate intensity for at least 20 minutes, allowing your body to use oxygen effectively to fuel the activity.
Aerobic exercise matters for health because it supports cardiovascular fitness, helping to improve heart function and circulation. Engaging in regular aerobic activity can lower the risk of heart disease, high blood pressure, and diabetes. It also plays a role in maintaining a healthy weight and can enhance overall mood and energy levels. The Centers for Disease Control and Prevention recommends that adults aim for at least 150 minutes of moderate aerobic exercise each week to achieve optimal health benefits.
In the body, aerobic exercise primarily uses oxygen to convert carbohydrates and fats into energy. As you engage in aerobic activities, your heart pumps more blood, delivering oxygen to your muscles. This process helps improve the efficiency of your cardiovascular and respiratory systems, making daily activities easier. Additionally, regular aerobic exercise can strengthen your heart muscle, allowing it to pump blood more effectively.
Overall, incorporating aerobic exercise into your routine can lead to better health outcomes and improved quality of life. It is an accessible and enjoyable way to stay active, whether you choose to participate in group classes or enjoy solo workouts outdoors.
