How do you measure energy expenditure?

Answer 1

It is actual a semi-complex equation to figure out (accurately) how many calories have been burned. Various factors have to included (age, weight, gender, activity, intensity, height, time span, ect.). There are many online sources that can do this, as it varies per person and per activity.

Answer 2

You can keep track of several aspects of the exercise you were doing. This could include type of exercise (running, swimming), duration (30 minutes, 1 hour) distance (2 km, 500 meters), speed (14 km/h, 1.4 metres per second). If you have an advanced piece of equipment you may even be able to take measurements such as heart rate and use a pedometer.

For example, when going on a walk, keep track of the distance you walk, and the time it takes you. Using these things to calculate the speed, or the 'intensity' of your walk, coupled with the time spent exercising and your weight can be easily put into a calories burned calculator to see how much energy you've burned off. See the related link for a good calories burned calculator.

Answer 3

The real answer is long and complex. In a nutshell, you're always burning calories to maintain basic functions and do daily activities. If you're referring specifically to burning more calories while you exercise: calorie expenditure moves in line with oxygen consumption which moves in line with heart rate. So if your heart rate is up and you're breathing hard, you are likely burning more calories.

Answer 4

A person's energy requirement is the amount of energy he or she needs to maintain health, growth, and a level of activity. A person's energy expenditure is the amount of energy he or she uses, and the measure of this can be used to determine the person's energy requirements. Energy expenditure can be calculated either with an equation or by direct measurement.

Answer 5

i cant tell you by minute but you can calculate the amount of kilojoules you burn by multiplying your weight by how long you train then multiply again by how intense the training was. so if you weight 60 kilos and you go for a 30 minute slow jog it would be 60 kg x 0.5 hours x 24 kJ. if it was a fast run it would be ... 60 kg x 0.5 hours x 40 kJ

Answer 6

If you just look at the nutrition facts, it will say how much 1 serving of the product is and how many calories are in 1 serving. Just make sure you count how many servings of a product you eat and multiply that by how many calories are in 1 serving. But make sure you measure out 1 serving or else it won't be accurate. You can't really calculate how many calories you burn on your own, but you can find out how many calories are burned in a certain activity online.

Answer 7

There are many tools that you can use to track how many calories you have burned during your last session of running. Here is a great website, http://www.mapmyrun.com/tools/calculators, that features a calculator to calculate the calories you have burned.

Answer 8

Combining your height, weight, gender, and length of exercise. This is applied against specific exercises based on the number of METS.

METS (Metabolic Equivalents) are where researchers have calculated the metabolic load for an activity.

For example, running has more METS than walking.

The amount of calories you burn per day is dependent upon your weight, height, gender, and level of activity.

This is called TDEE (total daily energy expenditure)

Even with no exercise you still naturally burn a set number of calories per day.
