Earlier quoted context omitted.

It happened on a stationary bicycle trainer -> Low load on joints, as most of the weight rests on the saddle and handlebars.

The University of Bath minimal HIIT protocol also used stationary bikes (3 20" intervals 3x/week).

Keep in mind that research in sports science is biased towards equipment like bikes because they make the study so much easier - safer to use, ensure consistent form, easier to get approval for the study and there's no need to coach the participants all that much.

Ah, the sprint is being rediscovered once again for it's ability to squeeze maximum effect into minimum working time. If you get a chance, try to find a copy of "A System of Multi-year Training in Weightlifting" by A.S. Medvedyev (a translation of the 1980s Soviet Olympic Weightlifting program for coaches). It's the culmination of decades of studies across the entire Soviet athletics program about what works and what…

Can you plz share how do you incorporate sprints in your training plan?

I would want about four of each rat still. The control could die of something else...

I'm quite confident the only reason to use four rats in a study of cyanide is that you really want to kill two rats.

Yeah, because you already have a very well-established prior on the effects of cyanide.

Jumping cold out of your couch/chair and sprinting 5 seconds every hour, multiple times a day, sounds to me like an optimized 'quickly destroy most of your body joints' routine.

To me - it sounds like a great way to throw up or at least get stomach sickness. I can't imagine going full send with no warm up and not suffering some sort of issue after stopping.

I don't know how to put this kindly, but eh... if you can't exercise for 20 seconds, you might be a bit out of shape.

Your analysis seems to be in the right direction but I think that the body uses this energy in many more ways than just heat. Moving muscles, pumping blood, keeping ionic gradients in the kidneys, and in cells, producing waste products, do seem to take energy. Also, consider the water we lose due to evaporation just by breathing, we are constantly creating a significant amount of heat and dissipating it into the envi…

The thing is that because of the 2nd law of thermodynamics, that energy does not go away when we use it. Moving muscles, pumping blood, etc uses energy and transforms it to heat. It's a bit weird that energy doesn't go away when we "use" it, but that's how the universe works :-) What can happen is that energy is locked up in chemical structures (or, I guess as physical potential energy). So if you evaporate water, th…

It's easier to measure the volume of exhaled air and extrapolate calories from that, via CO2 expelled.

Depends on your health. I'm 50 and healthy, I can easily "full send" a 30 or 60 second sprint. I have friends my age and younger who probably can't, for different reasons.

Warm up for a 20 second sprint on a stationary bike? Getting on the bike would be enough warm up...
