2. Because jogging is mainly aerobic respiration of muscle cells, running is mainly anaerobic respiration. According to high school biology knowledge, we can know that aerobic respiration consumes more sugar and releases it more efficiently. So jogging is better than running.

① Jogging belongs to aerobic exercise. According to the research of American sports medicine, glycogen is the main energy supply before aerobic exercise 15 minutes, and fat energy supply begins after exercise 15 ~ 20 minutes, so aerobic exercise is generally required to last for more than 30 minutes.

(2) Then, a problem arises, that is, people can easily exercise for 30 minutes or more while maintaining high intensity, such as 65%MHR. Does everyone have such basic physical fitness? Let's take a look at the concept of high-intensity exercise for 30 minutes, such as 65%MHR.

③ Adult women's 800m and men's 1500m long-distance running can generally reach the required heart rate, and most people should have had this experience in physical education class. The time to reach the standard is 4 ~ 5 minutes and 6 ~ 7 minutes respectively. In other words, running at a medium speed of 6 to 8 kilometers can achieve aerobic exercise of 65%MHR for 30 minutes.

Aerobic respiration mainly produces carbon dioxide and water, while anaerobic respiration mainly produces lactic acid. Can we pass carbon dioxide? Excessive breathing is excreted in time, and lactic acid accumulates in the human body, causing muscle aches.

Excessive running is also dangerous, such as:

Excessive running will overdraw your heart. ?

② Cardiovascular and cerebrovascular accidents are easy to occur.

③ Short-term harm of excessive exercise: In fact, after exercise, generally in a short time, about 1 or 2 hours, the resistance will drop badly, and then it is particularly easy to get sick at this time. For example, if you don't wipe your sweat clean, or catch a cold, it's easy to catch a cold.
