Nice overview by Anthony Colpo on latest high/low reps for strength/hypertrophy study
http://anthonycolpo.com/?p=3739

interesting that Anthony concentrate more on multiple vs single reps differences while leaving the issues of almost same hypertrophy for high/low reps alone

He has an entertaining way of writing. What was the p-value for the difference between 3x80% and 3x30% anyway? Wasn’t it pretty low?

Population population population.

Trained vs untrained.

He missed the most important aspect.

Indeed

I don’t find the study, but I guess the difference was low

Yeah, this too

here is an article about the same study which talks about the p value: http://bretcontreras.com/2012/06/powerful-stats/#comment-24058

I have some comments here. I will write a review about it.The p value doesn’t say anything meaningful.

I have an article on it for almost a year and just needs to finish it and get it published.

The p-value doesn’t say anything meaningful? You mean that you need confidence intervals as well, if so I agree. But saying that anything below 0.05 is good, proven this is how it works and anything above is “myth debunked” is simply wrong. A p-value of 0.05 is abritrarily chosen.

Or do you mean that you need the power as well? This is pretty easy to calculate.

I mean you don’t need p values if you have confidence intervals. People report p is either doing it because of the force of habit or they do not know much about CI.

There are lots of problems with p value and the arbitrary value is just one of them.

yeah, I agree that the CI is much, much better. Wouldn’t say the p-value is uneccesary, though. It provides information about the result of the statistical test. However, it should be reported together with the CI and the power.
