There are two methods to measure the basal metabolic rate. The first formula calculation method, as long as the height, weight, gender and age are input into the formula, can obtain the basal metabolic rate. The advantages of using the formula are simple and convenient, but the disadvantage is that there are at least five The formulas are not the same for each kind of calculation, and most of these formulas are designed by Westerners. Orientals are less applicable and the formulas are too old. In addition, they have the same height, weight, gender, and age. Two people, after calculating by formula, theoretically, the basal metabolic rate should be the same, but each person is different from each other and cannot be the same.

The following formula provided by the American Sports Medicine Association is generally used:

BMR (male) = (13.7 × weight (kg)) + (5.0 × height (cm)) - (6.8 × age) +66

BMR (female) = (9.6 x body weight (kg)) + (1.8 x height (cm)) - (4.7 x age) + 655

For example: Mr. Li, company employee, age 25, height 180cm, weight 65kg, his basal metabolic rate formula is: 13.7×65+5×180-6.8×25+66=1686.5 kcal

The second method is direct or indirect calorimetry, which uses the inhaled oxygen and exhaled carbon dioxide of the subject to calculate the basal metabolic rate through gas analysis and special conversion. The advantage is that each individual can be individually calculated to be more practical. The basal metabolic rate is numerical, but the disadvantage is that the machine is quite large and time-consuming to operate. It takes a lot of effort to check it.

For example, for a man, the body surface area is 1.5241 square meters. Under the basic conditions, the 6-minute oxygen consumption is 1.2L. The oxygen consumption is 12L per hour. The oxygen price is 20.19 kilojoules, divided by the body surface area. :

12 × 20.19/1.5241 = 158.97 kJ/m2/hr, which is the basal metabolic rate of the person.

In addition, for patients with low pulse and blood pressure fluctuations (such as those with heart disease and hypertension), we can use a simple method to calculate the basal metabolic rate:

Basal Metabolic Rate = [pulse (min/min) + pulse pressure (mmHg) -111] × 100%

Nowadays, all major and medium-sized health clubs have physical measurement equipment. You only need to hold the instrument handle or place the foot on the electrode according to the instructor's instructions. After a minute or two, you can know the specific data of your body composition. At the same time, your basal metabolic rate will also be roughly estimated based on relevant body indicators and formulas.
