Energy expenditure is the amount of energy a person uses during a given period of time.
It is usually measured in calories or kilojoules. However, energy expenditure can be affected by age, weight, activity level, and even outside factors like temperature and altitude:
Colder temperatures can cause a person to burn more energy to stay warm, while higher altitudes can cause a person to use more energy to breathe.
A person’s basal metabolic rate (BMR) is the amount of energy that they use to maintain basic body functions at rest. This includes functions like breathing, circulating blood, and digesting food. BMR makes up the majority of a person’s daily energy expenditure.
Energy Expenditure for Multiple Platforms and Activities
The energy you expend while walking, running, or cycling depends on several factors, including weight, the intensity of your activity, and the terrain.
For example, if you’re walking on a flat surface, you’ll expend less energy than walking up a hill. And if you’re running on a treadmill, you’ll expend less energy than running outdoors.
The bottom line is that the harder your body works – the more energy you expend and the more calories you burn.
So:
If you’re looking to lose weight, it’s important to choose activities that will help you expend the most energy.
