Some simple methods can be used to simply evaluate aerobic capacity.
Climbing test:
If you can climb to the third floor a little faster than usual, your aerobic capacity will be good and you won't feel obvious shortness of breath and chest tightness.
Pulse, blood pressure and activity test: lie down quietly and sit up quickly within 30-40 seconds. If the pulse accelerates 10-20 times per minute and the blood pressure drops less than 10mmhg, it means that the aerobic capacity is good. On the contrary, the pulse speeds up more than 20 times per minute, the blood pressure drops above10mmhg, and even nausea, vomiting, dizziness, cold sweat and other phenomena appear, indicating that the aerobic capacity is very poor.
Breathing test:
Light a match about a foot away and breathe hard. If you can put out the flame, you will have good aerobic capacity.
Low-intensity exercise test: after running in the same place for a period of time, the pulse increases to 120 times per minute, and then the activity stops. If the pulse can return to normal within 3-4 minutes, the aerobic capacity is normal.
Body mass index: Body mass index = weight (kg)/ height (m) squared, and the normal range of China people is 18.5.
