What is the intensity of exercise?

The intensity of our exercise is divided into three types: low-intensity exercise, moderate exercise and high-intensity exercise. We do not recommend that you try high-intensity exercise often, as it can easily lead to cardiovascular disease and affect your heart rate. Therefore, we recommend that you use low-intensity exercise to keep fit, such as running, playing badminton, etc., but you must pay attention to exercising in moderation.

Exercise intensity refers to the degree of physiological stimulation of the human body by physical exercise. It is one of the factors that constitute the amount of exercise. Commonly used physiological indicators are used to express their values. If the amount of exercise in school physical education classes is measured by heart rate, it is generally believed that an amount of exercise below 120 beats/minute is small; 120 to 150 beats/minute is medium; 150 to 180 beats/minute or more than 180 beats/minute is large.

Generally speaking, ultra-vigorous exercise is not good for your health. Physiologists have conducted two studies. One is to compare the effects of low-intensity and high-intensity exercise on the human cardiovascular system; the other is to measure the changes in blood pressure and heart rate during continuous and intermittent exercise. The results show that both low-intensity and intermittent exercise can have a positive impact on health. Therefore, experts suggest that daily low-intensity exercise is not only good for health, but also can reduce the risk of heart attack.

Exercise can improve heart and respiratory function, increase muscle strength and bone density, improve reaction sensitivity, reduce depression, and thus enhance physical fitness. Therefore, many people believe that increasing the intensity and duration of exercise will be more beneficial to health and longevity. In fact, this is unscientific. Tai Chi is a slow and gentle exercise. Research by Chinese scholars has found that practicing Tai Chi for 30 minutes a day can significantly increase the level of high-density lipoprotein in the body after one month.

Regarding the intensity of exercise introduced in this article, I believe you all know that there are several types of exercise intensities. The best intensity for us in life is low-intensity exercise. I hope everyone should pay attention to it in daily life. For friends who like sports, you should do it within your ability and avoid overdrawing your physical fitness frequently.
