Question about "muscle endurance"
Coach,
I'm not exactly sure where to begin or how to formulate my question, but I believe that I'll get the idea through.
I'll define "muscle endurance" as the number of reps that one can do with a specific (low) weight.
Strength is force production capacity; the more force ones muscles can generate, i.e. the heavier a weight one can move, the stronger one is.
Endurance is the adaptation of producing more red blood cells to transport oxygen, the muscles' storing capacity of glycogen, and as far as I understand, the muscles' "efficiency" in converting that glycogen to kinetic energy, i.e. the better the muscles are at it, the more reps X grams of glycogen will permit you to perform. I guess that this mystical "efficiency" also entails that the muscles are better at utilizing oxygen, so the more "efficient", the more reps your muscles can do with X liters of oxygen.
Now, obviously strength = higher work capacity; strong muscles need less energy and oxygen for a submaximal rep, the more submaximal that the rep is, i.e. the stronger the muscle is.
... my understanding of "muscle endurance", is that it's determined by strength (submaximal reps are easier, thus a greater number of them can be performed), by "endurance" (oxygen transportation and glycogen storing capacity), and, by the muscles' efficiency in using both oxygen and chemical energy.
So my question is made up of 1) is my understanding of "muscle endurance" correct, if not, how does it work, 2) is that thing about the muscles' "efficiency" in burning calories right, and 3) if there is such a thing as "muscle endurance" (whether it's as I understand it or not, as long as it's even a thing), is it a thing that some athletes should be physiologically adapting to specifically, or is strength + prowling the way to go (except for swimmers, long distance cyclists, marathoners etc)?
