How many calories does climbing stairs burn?

Climbing stairs is a very effective aerobic exercise. This exercise can be seen everywhere in life. It is a very convenient and quick way to lose weight. So how many calories can generally be consumed by climbing stairs? First of all, the energy required for a normal person to climb a flight of stairs is generally about 240 calories, but the efficiency of the human body is very low. Generally, only about one-fifth of the energy is actually used by the body, so the efficiency is very low.

A simple calculation will show that climbing stairs is very effective in losing weight. Suppose a person weighing 60 kg lives on the fifth floor. If the height of each floor is 4 meters (vertical height from the ground), how much energy is consumed each time he goes up and down the stairs? For each floor he goes up, his muscles have to do 60 X 4 = 240 kg-meters of work. For five floors, the work required is 240 × 5 = 1200 kg-meters.

However, the mechanical efficiency generated by human muscle contraction is very low. Only about 20% of the energy is used for work (such as raising the body or moving a certain distance), and the other 80% of the energy is converted into heat energy and dissipated in the form of body temperature. Thus, 1200 kg-meters must be divided by 20% mechanical efficiency, so the workload of going upstairs is

Generally speaking, going up the stairs will generate about 6,000 calories, while going down the stairs will generate much less calories than going up the stairs, usually at about one-third of the total, which is about 2,000 calories. So generally speaking, the total amount of going up and down the stairs is about 8,000 calories. Taking into account the actual utilization of energy, going up and down the stairs generally consumes about 80 grams of energy.
