I'm confused. "Hourly 4s sprints" sounds like one 4 second sprint every hour but the second paragraph of the summary says > Purpose > 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-…

Me too. Title is confusing

Don'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.

Ok 4s/hour. 8 hours/day of sitting. So 32s day of total exercise!?! Still probably will not do it.

That is also how I initially read it, but the paper states that there were 5 sprints per hours for a total of 160 seconds a day. From the paper: > i.e.; 4-s x 5 per h x 8-h = 160-s per day

Still probably would not do it. But why?

I wonder what other exercise modality this could be replaced with. Do 3 squats?

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.

You can do low impact. Burpees aren't too rough.

Every hour, they do a workout that consists of 5 repetitions of 4s sprints.

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…

Fairly easy to incorporate this into a pomodoro cadence. Every other break do some high intensity bursts.

Earlier quoted context omitted.

1 flight of stairs.

Well, presumably you can work while resting. Honestly, I haven't found that to be too hard (I take a mid-day bike ride up the hill here in SF).
