Influence of incline/speed on metabolic test

    When you do a metabolic test on a treadmill, you can vary either
    speed or an inclination.

    Intuitively, it seems that if your running speed is not great you will struggle more
    when speed is getting faster.

    I haven’t done this experiment myself, I am wondering how each variation effect results of metabolic test (max HR, thresholds, VO2max). Are the difference within small range or
    are they quite large?

    Make the test as specific to your physical experience as possible.

    I have a lot of uphill experience (first as a climber for fifteen years, then as a skimo racer for six). So my body “knows” how to go uphill.

    In contrast, I only ever run out of necessity. I don’t do it for its own sake and I don’t have a significant amount of training hours in it. (Perhaps a couple thousand hours for running compared to many thousands of hours going uphill).

    So if I run at a high heart rate, my legs are dying, and I would be sore for days. I don’t have the mechanic efficiency or strength endurance to run fast for very long without destroying my legs. In contrast, I can go uphill quite comfortably at similar heart rates without much fatigue unless it’s at a truly high intensity.

    Similarly, if I did a fitness test on cross country skis, it would be laughable. My inefficiency is so bad that I probably couldn’t go very hard at all, and I would be destroyed afterward.

    So with testing on a flat or inclined treadmill, I always go with an incline if I want something sport-specific. I only test on a flat treadmill out of curiosity, not to inform my training.

    Does that help?
