Exercise intensity refers to the energy consumed by exercise in unit time. It is usually expressed by the percentage of maximum oxygen uptake (also known as maximum oxygen consumption) and the energy metabolism rate of heart rate per minute.

The maximum oxygen uptake during moderate intensity exercise is 50%-60%, and the heart rate reaches 1 10- 130 times per minute;

What is aerobic exercise?

It has become common sense that life lies in exercise. Having a good body is the most basic condition for enjoying life, and I believe no one will object. Doctors always advise people to do exercise to strengthen their physique. But at the same time, people always ask doctors, "What kind of exercise is good?" "How much exercise is enough?" . Faced with this most common problem, Dr. Kenneth H. Cooper, MD, of the Sports Research Office of the US Air Force, created the world-famous "Aerobic Exercise Method" and its exercise prescription after years of research and exploration. Once known to the world, it immediately swept the world. It is an exercise and fitness method recognized and practiced by the most people in the world.

Aerobic exercise refers to long-term exercise (endurance exercise), which can fully and effectively stimulate the heart (blood circulation system) and lungs (respiratory system) and improve cardiopulmonary function. So that all tissues and organs of the whole body can get good oxygen and nutrition supply and maintain the best functional state. Common ways are long-distance running, skipping rope and swimming.
