# Energy Cost of Stair Climbing for Average-Sized Individuals

• kthejohnster
In summary, stair climbing can burn around 10-12 calories per minute for a person weighing 150 pounds, making it a good form of exercise for building leg strength, improving balance, and aiding in weight loss. However, its impact may not be as significant as other high-intensity activities and precautions should be taken, such as starting slowly and consulting a doctor for those with pre-existing medical conditions.

## Homework Statement

How much mechanical energy is needed for avg size person to climb climb up nine flights of stairs?

E=KE+PE
PE=mgh
KE=1/2mv^2

## The Attempt at a Solution

person is about 80kg
g=9.8ms^-2
h is about 3 meters per floor for 10 floors = 30m

so at top, when the person stops climbing there is only PE so E=0+80*9.8*30=23520J

isn't this only like 4 kcals? doesn't that seem low?

Your equation is OK. Did not check your numbers.

Maybe that is why people need to climb many stairs to lose weight!

## 1. How many calories can you burn by climbing stairs?

The number of calories burned while climbing stairs varies depending on factors like weight, intensity, and duration. On average, a person weighing 150 pounds can burn around 10-12 calories per minute while climbing stairs. This means that a 10-minute stair climb can burn around 100-120 calories.

## 2. Is stair climbing a good form of exercise?

Yes, stair climbing is an excellent form of exercise as it works multiple muscle groups and can provide a cardiovascular workout. It also helps in building leg strength, improving balance, and burning calories.

## 3. Does stair climbing help in weight loss?

Yes, stair climbing can contribute to weight loss as it burns calories and can help in creating a calorie deficit. However, weight loss results also depend on other factors like diet and overall physical activity level.

## 4. How does stair climbing compare to other forms of exercise?

Stair climbing can be an effective form of exercise, but its impact may not be as significant as other high-intensity activities like running or cycling. However, it can still provide numerous health benefits and may be a more accessible option for some individuals.

## 5. Are there any precautions to take while stair climbing?

Like any exercise, it is essential to take precautions while stair climbing to avoid injuries. It is recommended to start slowly and gradually increase intensity, use proper form, and wear appropriate shoes. People with pre-existing medical conditions should consult their doctor before starting any exercise routine.
