Is aerobic exercise harmful to the heart?

On the contrary. Your heart and lungs are the source of your vitality. Aerobic exercise is the abbreviation of "aerobic exercise" or "cardiopulmonary exercise". If an exercise mode is to be regarded as aerobic exercise, it should be (a) rhythmic, (b) using large muscle groups and (c) continuous. The more muscles involved in activities, the harder your heart must work to provide energy for them.

Therefore, it becomes more and more powerful. Low-impact or non-impact activities, such as boating, swimming, cross-country skiing, walking with poles … all these will absorb the muscles of the whole body without making it jump. If you care about joints, then humans are not suitable for long-term impact. Plus some intervals, you have an ideal exercise method.

When you train your heart, it will pump blood more effectively and increase your endurance over time. Having said that, everything should be moderate, including occasional moderation. Aerobic exercise can not only improve heart health and oxygen content in blood, but also activate your immune system and release endorphins, which are your natural painkillers.

But long-term aerobic exercise may do more harm than good, leading to the release of stress hormone cortisol. When too much corticosteroid is released, it may lead to catabolism, tissue decomposition and chronic diseases. Excessive aerobic exercise, such as running a marathon, may lead to an increase in the level of myocardial enzymes in the blood, which is a sign of heart disease (such as myocardial scar).

In order to get the most benefit from exercise, you need to push your body big enough to meet the challenge and have enough time to recover and repair. One of the best methods is interval training. This is unparalleled in preventing heart disease and diabetes, losing weight and effectively improving fitness level.

Strategy: Combine short-term high-intensity exercise with slightly longer active recovery time. So if you are a race walker, you can alternate 3 minutes at normal speed and 1 minute at fast speed. Increasing and decreasing heart rate can improve blood vessel function, burn calories, and make the body remove fat and sugar from blood more effectively.
