This was done on purpose Every hour but you can get similar results with one longer Training session. Heck I only train 3-5 days per week and problem burning fat with enough intensity or volume.

Re: Hourly 4-second sprints prevent impairment of postprandial fat metabolism
#53> This study determined if the interruption of prolonged sitting (i.e.; 8-h of inactivity) with hourly cycling sprints of only 4-s duration each (i.e.; 4-s x 5 per h x 8-h = 160-s per day; SPRINTS) improves PPL. The 4-s sprints employed an inertial load ergometer and were followed by 45-s of seated rest. So you would need to take a 5 x (4-s sprint + 45-s rest) = 245 seconds exercise break from work every hour and in…
I think we get energy directly out of carbohydrates and proteins, too. If so, that factor will be (¿much?) lower.

#55Jumping 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.
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).

#56Earlier quoted context omitted.
> Does "whole body fat oxidation" mean that the an average male calorie burn of 2500 per day would be multiplied with 1,43 to 3575 calories per day? It seems extremely unlikely to me. I hesitate to bring up the 2nd law of thermodynamics because I know if frustrates a lot of people in these discussions. However, bear with me. "Calories" in this context refers to kilocalories. Burning 1 kilocalorie produces enough ener…
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, the energy goes into the water and stays there until the vapour condenses. Things like that. But it's pretty easy to isolate a person and measure the amount of heat they produce (to a gross level like we are talking about here).
But, yes. Exercise will drive your metabolism and cause you to be warmer.

#57Don't we need to warm up before doing any max intensity exercise to prevent injury.
I've read conflicting information about warming up over the years but it at least appears to me that the consensus is slowly moving away from several common exercises such as stretching, which apparently even seems to have negative effects.
Static stretching should be avoided at the beginning of a workout.
I had assumed this was about sprinting in the sense of running as fast as possible, which would be absolutely insane to do without a warmup. I take around 20 minutes to warm up for sprinting, doing very specific exercises to prepare.
On a stationary bike though, because the range of motion is much more controlled, I can see it being a little less of an issue.

#58p(0.05) and p(0.0001) with 8 people sample? It is hard to understand those probabilities.
Re: Hourly 4-second sprints prevent impairment of postprandial fat metabolism
#59I think this is mostly a curiosity. Why do people think this is relevant for HN? Is people seriously trying to "hack" their metabolism? What for? Being able to spend, say, 16 hours sitting in front of a computer typing code away?
As I get older, I more and more realise the negative health impacts of a mostly sedantry job - anything to offset that is surely in the interests of most HN readers

You won't be cold though, because you're doing 4sec of exercise 5 times an hour.
