I'm not a medical researcher; is this a normal size for a study?

I thought the exact same. I honestly think this post should be deleted on that fact.

It's enough for such a large effect, but obviously it doesn't tell us anything about the long-term impact of trying it as a lifestyle.

#5Ok 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

Say you are trying to distinguish between a placebo and a cyanide pill; test subjects are young rats (base rate of death extremely low). How large of a sample size do you need? I think one control, one test subject is enough to be certain, because the base rate of death is insanely low, when measured on a per-minute basis.
Sample sizes can be small and still very significant when the effect is large.

There are two problems: "No differences (p>0.05) between interventions were found for plasma insulin or glucose AUC." That can very, very much be explained by lack of power. But the main problem is that a group of 8 people has a very low probability of generalizing across the population. And of course, very few people sit 8 hours without moving.
That said, it's more than promising enough for further research.

#9The control group was asked to sit for 8 hours straight, whereas the experimental group sprinted five times. It would be more interesting if they compared it to standing up.

My uncle smoked 3 packs a day and lived to 90.
other than that, maybe just getting up and putting strains even for seconds might do the job /trick our body.
