The notion that low-intensity stead-state endurance work is required to elicit an increase in stroke volume is an outdated one, an assumption made from early observations that stroke volume appeared to ‘plateau’ at around 40% of VO₂max. However, a large body of research has since demonstrated that no such plateau exists, especially amongst elite-level ...

I imagine it has something to do with him being a full-time professional athlete with multiple full-time coaches optimizing his training.

No, because it would be impossible for a fight to be of such low intensity and long duration that slow twitch fibres would have an advantage. Slow twitch fibres are only advantageous during prolonged submaximal (aerobic) exercise activities like long distance running and cycling. So in a 50km bicycle race, comparing two people with different fibre type ...

I think you're vastly underestimating the endurance capabilities of fast twitch muscle fibres. A person's proportion of muscle fibre types is not as limiting as you think it is. Type I ("slow twitch") muscle fibres generate ATP (the fuel that the muscle uses) primarily through the aerobic energy system, and have a slower speed of contraction and ...

Say MJ sprinted and slam dunked. He then used all his muscle fibers both fast twitch and slow twitch. After that followed say 3 minutes of running around at moderate speed. During this time his fast twitch fibers were recovering and he was only using his slow twitch fibers. After the 3 minutes had passed he was ready for another sprint and slam dunk. This ...

I think this question has more to do with why a person with a lot of fast-twitch muscle types have higher stamina. Especially if you pair it with this question. First, there are actually three types of muscle fibers. Type 1 (slow-twitch), type 2a (fast-twitch), and Type 2b (super-fast-twitch. Also called Type 2x). Type 2a is kind of an in between between ...

Studies have shown that caffeine causes a dose-independent improvement in endurance performance1,2,3, which means that you get the same effect from taking a very large dose as you would with taking a small dose, presumably above some minimum threshold dose. (And the maximum dose given in these studies, with no negative effect on performance demonstrated, was ...

Improve overall health through fitness (for me this would include losing some weight, I hover around 190lbs as a 6'0" male, ~37 years of age). Maintain decent strength for a variety of activities. Become better at endurance athletics, in particular, running. I'll address these in a different order than you have posed. Running Simply put, the way to get ...

I can't remember who it's from, but there's a quote about this. Something like: Wrestlers and other athletes are in shape, but boxers are always the fittest athletes. Why? If a runner gets tired, he loses the race. If a wrestler gets tired he gets pinned. But if a boxer gets tired, he gets the ever-loving shit beaten out of him. Combat sports are ...

Is kettlebell swing an exercise that you can, with enough training to adapt, do for hours, just like you can row or swim for hours? Yes. Though obviously there's an individual upper limit on how heavy the Kettlebell could be, as their total power output (the amount of work put into each swing multiplied by the frequency with which they're performing the ...

I'm not able to answer your question definitely, but here's a thought experiment with squats. Strong person has a squat PR of 200kg Weak person has a squat PR of 40kg Who do you think will manage more reps with a weight of 40kg? So i'd say, all else equal then yes, the stronger person also has more stamina.

Injuries can certainly hinder our training routine, but endurance is something you can continue to practice! Mental endurance can be just as important as physical endurance, and they tend to work hand-in-hand. Our mental fortitude contributes to our ability to withstand prolonged physical effort. Given your injury is currently physically limiting, it is a ...
