# Running Vs Walking wrt calories burn. (mathematical question).

• MathematicalPhysicist
In summary, the conversation discusses finding the minimum value of parameter B for a person to burn the same number of calories while running a distance x compared to walking a distance Bx. The question relates to the field of bio-mechanics and a recommendation is requested for a mathematical bio-mechanics textbook. Experimental data is needed to calculate B, specifically data on energy consumption and MET units. The MET factors for exercise levels are defined in a study measuring oxygen consumption. A request is also made for a MathJax tutorial.

Suppose we have a person, A, who we know his/her physique and biological properties, assume he runs a distance, x, versus the same person walking a distance Bx, where B is some parameter we're doing our optimization on which is >1.

Can you find me the minimum value of B for which the same person burns the same number of calories in both running a distance x vs walking a distance Bx?

BTW, is this sort of question relates to the field of bio-mechanics?

Can you recommend to me rigorous mathematical bio-mechanics textbook?

This should give an exact number of B, not a minimum.

Do you have experimental data? That should be easy to calculate.
It is impossible to calculate it without any data.

I am not sure, which data do I need to know to calculate B, and which are the equations in use here?

Some data about energy consumption to run/walk some distance.
I would expect that those vary from person to person.

This is usually calculated with MET units(metabolic units) and is part of standard exercise physiology enrgy mensuration.

MET = Kcal / ( hours * kg ). Theoretically, the only information needed is the weight of the person (there is an age factor in the 2011 tables) exercising, the time the person spent doing whatever physical exercise.

The MET factors for exercise levels are defined in :

http://www.ncbi.nlm.nih.gov/pubmed/21681120

The data was derived by measuring oxygen consumption on a spectrum of people of different ages, weights, sexes, performing defined activity levels, like running speed == 4:17 mile pace on a treadmill. Of course not every older person can run that fast.

Where is our MathJax tutorial, please? [itex] tags do not seem to play anymore.

## What is the difference in calories burned between running and walking?

The number of calories burned while running and walking varies depending on factors such as weight, pace, and distance. However, in general, running burns approximately twice as many calories as walking for the same distance.

## How does speed affect the number of calories burned?

The faster you run or walk, the more calories you will burn. This is because your body has to work harder to maintain a faster pace, which requires more energy.

## Does distance make a difference in the number of calories burned?

The distance you cover while running or walking directly impacts the number of calories you burn. The longer the distance, the more calories you will burn.

## Is weight a factor in the number of calories burned?

Yes, weight plays a significant role in the number of calories burned while running or walking. Heavier individuals will burn more calories than lighter individuals for the same distance and pace.

## Does running or walking on an incline affect the number of calories burned?

Running or walking on an incline, such as a hill or on a treadmill at an incline, requires more effort and therefore burns more calories than running or walking on a flat surface.
