#92'Hourly 4-second sprints' is actually 5 times an hour 4 secs (bicycle) sprints. So it is more precisely about every 12 minutes. I do not understand why it says 'hourly'? Because it sounds less often?
It must be one set of 5 reps per hour, not one sprint every 12 minutes. That's how exercise usually works, and the study is concerned with the "least amount of exercise that can acutely improve fat metabolism and other aspects of health". Activity spaced out every 12 minutes would be disruptive and defeat that purpose.
Thank you, so that explains the 45-s rest mentioned.
I assume then each 4-s workout is followed by a 45-s rest. So 49-s * 5 = 245-s (4 min) spend each hour on the excercises.

Right before the pandemic, I entered a body composition challenge that just ended. I lost ten lbs of fat and gained one lb of muscle. Another guy lost 6 lbs of fat and gained 4 lbs of muscle. You can't trust your scale. Go by the scale in addition to how you look, how your clothes fit, and your body measurements.
For better data, get a Dexa body scan.

#95> 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…
No it means the amount of calories coming from body fat is increased by 43%, which may amount to nothing over the course of the day if it also simultaneously increases appetite. Almost all forms of weight loss suffer from this problem - the amount of fat lost is generally proportional to the long-term appetite increase, so that 95% of people regain the weight.

#97Earlier quoted context omitted.
Since you're doing this every 12 minutes, you'd stay relatively warm all day. American football players don't need to warm up every time they come off the sidelines
But they do... lots of teams have stationary bikes on the sidelines. No athlete would sit motionless for 12 minutes in the middle of a competition, not too mention that players would go through a much longer warm up before the game. But I agree that going full force very briefly on a stationary bike with no warmup is probably fine for most people.
Fair, but a lot of them do sit on the bench and do some moderate walking at most.
I'd expect people doing these regular sprints to be more aware of their body and move around more in anticipation of the next set.

#98I 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?
Being sedentary seems to be really bad for you and programmers are the forefront of this as we spend lots of time motionless.
There seems to be correlations with major diseases as well as muscular skeleton pain. It’s not even 16 hours. Even 8 hours seems to be bad,(especially if it’s not spread out), since we live in a pretty sedentary world now.
I’ve been following these threads on hacker news as I want to prevent as much pain and diseases as I can.

#99"Four men and four women participated in two trials" I'm not a medical researcher; is this a normal size for a study?
Medical research is expensive to conduct, so it's not uncommon to see N<20. Additionally, more data is not necessarily better data since humans lie and it's unethical to force their compliance, so there's more of a risk for bad data with large trials. And throwing out bad data is selection bias.

Yeah go irradiate yourself just to find out how fat you are, what could go wrong?
