Climbing Stairs: burned calories and physics

Need a good workout without the tedium of TV? You can always opt for walking up a tall building's stairs. But do stationary stair-climbing machines outshine the real deal? It's not only about burning calories, it's a physics conundrum. Let's dive in!

The Energy Game

A calorie is an unit of energy, used to define the amount of energy required to increase the temperature of 1 liter of water by 1 degree Celsius. In physicist's lingo, energy is measured in joules. Lifting a textbook from the ground to a table takes only about 10 joules, give or take.

The work-energy principle tells us that the total work done on a system equals the change in its energy. The energy input or output is what we call work, and it's achieved by applying a force over some distance.

A Closer Look at your Energy

Let's focus on the system constituting the book and the Earth. The book can move, hence it may possess kinetic energy. As for the Earth, the important one here is the gravitational potential energy, which depends on the book's mass, the gravitational field, and its height from the floor.

Using this setup, the work-energy principle boils down to:

The Calorie Comparison

Both activities - climbing real stairs and using a stair-climbing machine - involve doing work against gravity. In the case of either, if you move your body's center of mass upward by a certain vertical height, the work done is approximately the product of your mass, the acceleration due to gravity, and the total height ascended.

Differences in Approach

  • Real Stairs
  • Energy Expenditure: Main work is lifting your body against gravity through each flight of stairs. Noticeable winds or external factors are negligible indoors.
  • Physics: The work done is the product of your mass, the acceleration due to gravity, and the total height ascended (( W = mgh )).
  • Extra Considerations: Energy used for landings or accelerations/decelerations may be slight, but they are still a fraction of the total for healthy walking.
  • Stair-Climbing Machine
  • Energy Expenditure: The machine simulates climbing stairs by continuously moving steps or a belt upward, requiring you to lift your body’s center of mass with each step.
  • Physics: If the machine accurately mimics the vertical movement, the work done is again the product of your mass, the acceleration due to gravity, and the total vertical displacement (( W = mgh )).
  • Practical Differences: The machine may allow for more precise calibration of resistance and more consistent tracking of calories, but its fundamental physics remains the same.

Calorie Burning and Efficiency

Both methods will burn roughly the same number of calories if the total vertical height climbed is the same. Although real stairs may have minor variations due to turns, landings, or step height, stair-climbing machines are designed for consistent resistance and step height, simplifying calorie tracking and workout consistency.

In the End

The work-energy principle is applicable to both activities. Comparing the energy expended, both methods would burn approximately the same number of calories if the vertical work (height climbed) is the same. But stair-climbing machines offer a more controlled environment for precise calorie burning and training.

  1. While discussing calorie burning during exercise, consider comparing the energy expended in climbing real stairs and using a stair-climbing machine, as both activities employ work against gravity.
  2. In terms of energy consumption, thecalorie comparison between climbing real stairs and using a stair-climbing machine implies that,if the total vertical height climbed is the same, both methods would burn roughly the same number of calories.
  3. Newsletters on health-and-wellness and fitness-and-exercise might include stories about the calorie-burning efficiency of stair-climbing, highlighting the similarities between real stairs and stair-climbing machines according to the work-energy principle.
  4. Articles centered around science, climate, and AI could delve deeper into the intricacies of the work-energy principle, exploring its application not only in exercise but also in other facets of our lives, such as energy production and environmental conservation.
