How to calculate the calories burned by exercise?

Calorie is the transliteration of French Calorie, which is the unit for calculating calories, and it is divided into big card and small card. 1 calorie is equivalent to the heat used to raise 1 liter of water to 1 degree Celsius at 1 standard atmospheric pressure; 1 calorie equals 1000 calories.

All the calories our body needs come from food. When eating, the chemical action of human metabolism decomposes food and converts it into energy.

Daily activities, from breathing to running a marathon, are driven by burning calories.

Combustion heat is one of the metabolic processes. If the body needs enough oxygen, water and food, cells will work actively to burn calories at the best speed. Therefore, a healthy diet, good digestion, proper minerals and vitamins and regular exercise are indispensable.
