Makers of fitness treadmills usually include an adjustment for the treadmill surface incline. This allows the running surface to be tilted upward by a maximum of 10-15 degrees and it is supposed to simulate a more strenuous run up a hill.
But how can this be more strenuous? The runner is stationary and remains at the same height as the treadmill track moves under him. No work is being done against gravity. It is like climbing up on a down escalator. As the foot is placed up on the step the step then moves downward.
Is a treadmill incline just a marketing ruse that actually has no...
Why does it cost roughly the same effort to run against an inclined treadmill as up a hill of the same inclination? That is neglecting the movement of the legs and the bobbing up and down as we run and the wind resistance. I remember being told in school physics that there is no work done unless a mass is accelerated or raised. To a first approximation, on a treadmill we do not ascend and we do not accelerate.
When running up a hill you are going up. So the treadmill should be nearly effortless as you are not raising a weight hence not doing work. Of course it is not effortless so where is...
Usually, I like to take a physical approach to phenomena that occur in everyday life. But I feel difficult to solve problems because I don't have higher education
Factors such as air resistance are not considered.
