Measurement standard of physical activity level: calculation of metabolic equivalent basal metabolic rate. In the past, several formulas have been proposed by different organizations, and the American Dietetic Association (ADA) provided the so-called Mifflin-St. Jill formula. Generally speaking, it is more accurate: male BMR = (10 weight /kg)+(6.25 height /cm)-(5 age) +5 female BMR = (10 weight /kg)+(6.25 height /cm)-(5 age). For a male aged 175cm/75kg/33, his basal metabolic rate is: (1075)+(6.25175)-(533)+5 =1674 (kcal/day). For women with the age of 160cm/50kg/25, it is: (65444). -161=1214 (calories/day) * If you are too lazy to calculate by yourself, you can also fill in this website (in English) or refer to another calculation method provided by a private clinic (in Chinese), and the program will automatically calculate it for you.
The level of physical activity is usually distinguished by intensity, and the calculation standard of intensity is metabolic equivalent (MET). In our daily life, work and exercise, the body needs energy to carry out. In this process, the body will consume oxygen for metabolism to provide energy, and metabolic equivalent is a unit to measure the oxygen consumption rate during physical exercise. 1 MET is approximately equivalent to the oxygen consumption per minute when a person is sitting in a quiet state without any activity. The greater the MET value, the more energy consumed and the higher the exercise intensity. The intensity of physical activity based on metabolic equivalent is divided as follows:
Metabolic equivalent activity intensity indicates that ≒ 1 MET is physically inactive? Limited to the content of static life, that is, most of the daily time belongs to sitting posture. ? For example: sitting at work, watching TV, chatting or driving. 1-3 METs mild physical activity? Light physical activity with little effort belongs to daily physical activity. ? For example: walking or walking with light objects. 3-6 METs moderate physical activity? Moderate physical activity, able to speak comfortably 10 minutes or more, but unable to sing. This kind of activity will make people feel a little tired, breathing and heartbeat are faster than usual, and they will sweat. ? Examples: race walking, downhill, medium-speed swimming, tennis doubles, badminton, table tennis, volleyball, Tai Ji Chuan, dancing, medium-speed cycling, etc. > > 6 METs strenuous physical activity? Physical activity is laborious. If you continue to engage in it for more than 10 minutes, you can't talk with people easily while exercising. This kind of activity will make your body feel very tired, your breathing and heartbeat will be much faster than usual, and you will sweat a lot. ? Examples: running, mountain climbing, continuous fast swimming, stair climbing, aerobic dance, fast cycling, taekwondo, rock climbing, skipping rope, playing ball (such as basketball, football, tennis singles), etc.
