Basic physics. Assuming you are generally healthy, your body is not usually in an oxygen-depleted state. Therefore it will take some amount of time in a state of increased oxygen use to cause oxygen depletion. Therefore, "the shorter your exercise, ... the less likely you are to cause an oxygen-depleted state".
Depending on your fitness level and exercise level, it will take more or less time to put you into this state. An overweight, sedentary person sprinting will be there pretty much instantly. A marathon runner walking briskly won't get there in any amount of time. But all things being equal, more time exercising will be more likely to put you into an oxygen-depleted state (and glucose depleted state, and elevated heart rate).
- darkerside 10y agoFor endurance athletes like your marathon runner, this is certainly the case. Strength and power athletes can certainly expend far more energy in a shorter time than someone who is less fit. It's a bit of a paradox where the better shape you are in, the sooner you can tire yourself out. From everything I've read, it certainly seems possible to reach oxygen depletion in a very short period of time. https://mobile.nytimes.com/blogs/well/2016/04/27/1-minute-of-all-out-exercise-may-equal-45-minutes-of-moderate-exertion/?referer= https://mobile.nytimes.com/blogs/well/2016/04/27/1-minute-of...
