Re: Redefining the relationship between Power and Intensity

The question came up for me because I revalidated my L1 last weekend and they are still saying that Intensity ≣ Power, where the triple bar indicates strict equivalence, or that Intensity defines Power.

The reason that bothers me is that in my experience, the other relationships taught in that lecture could easily be brought back into a high school or entry-level college physics or mechanical engineering or exercise physiology course and put directly to use in a homework project without raising many faculty eyebrows. They are on solid enough ground to be useful across broad modal domains scientifically, but if a student tried to claim that Intensity ≣ Power in the same classes it would be very likely to be contested.

I agree that part of the confusion is due to the common conflation of the terms "intensity" and "effort" in the realm of physical fitness and training. The relationship between effort and actual, measured power output is complicated by many factors including efficiency and fatigue, as well as structural factors.

We can all agree that maximizing results is dependent upon eliciting sufficiently high levels of intensity under the proper conditions. That is not in dispute. I am just questioning whether it might be useful to revisit that specific definition in that specific context to see if it can't be improved.

(I can't help but wonder whether the claim that Intensity ≣ Power would raise Dr. Glassman's eyebrows, stickler for scientific accuracy that he is.)
