How human energy is consumed
How

human energy is consumed by it we look at some of the data:?

(1), to maintain the basal metabolism: basal metabolism is the body is awake, at 18 degrees C & mdash ; 25 degrees Celsius environment, nerves, muscles completely quiet and fasting (12 hours ago to stop eating) the minimum necessary to sustain life energy requirement of about 60% -75% of the total energy consumption, which is the total energy consumption of major. Part generally higher in men than women, children, adolescents than adults, when cold than when warm

normal basal metabolism of the following:.

normal basal metabolic rate averages = energy / body surface area * h

body surface area = 0.00659 * Height (cm) + O. 0126 * Weight (Kg) -0.1603

generally a normal human basal metabolic rate is relatively constant, a normal adult metabolic rate in 20 years will not deviate from the normal 5% -10 %, same age, same weight, same sex differences in normal adults most basal metabolic rate within 110%.

(2), engage in labor consumed energy: the energy consumption of labor and labor intensity, duration, and the work of labor proficiency in physical activity related to energy consumption for 30% of total energy in general is usually divided into five labor intensity, such as: < / p>

①, very mild physical labor: in a sitting job, such as office work, meetings, reading, assembly, repair watches

②, mild manual: standing-based work, such as shop assistants, teachers, etc.

③, moderate physical labor: operating heavy machinery, tractor driving, car driving, general farm labor

④, heavy physical labor: Non-mechanized agricultural labor, semi-mechanized handling work, steel, sports activities, etc.

⑤, very severe physical labor: non-mechanized loading and unloading work, mining, logging, land reclamation, etc.

(3), specific dynamic action of food: food intake because the body extra energy metabolism caused by increased food called food specific dynamic action specific dynamic action of the additional energy consumption caused about 150 kcal -200 kcal, equivalent to 10% of the total energy
