Why Is It Harder to Run on an Inclined Exercise Treadmill?

It is a known fact that it takes a greater effort to run on an exercise treadmill when it is inclined with positive slope than when it is in a horizontal position. The reason seems simple: walking on an inclined treadmill is somehow equivalent to walking up a hill with the same inclination; when we walk up a hill, our own weight does negative work (or, in other words, we gain potential energy as we ascend) and therefore we have to do more work to compensate for it (or, in other words, we must supply the potential energy increase).
