What part is interesting?
I thought that post workout carbs + protein has been conventional wisdom for a while now. Actually, I don’t think immediate post workout protein is a necessity as long as daily protein is optimized but it usually creates an opportunity for a scoop of whey to help with that optimization.
I think the milk industry has been funding researchers in this area for a while. Chocolate milk for the win!
Tim Podlogar supervising some graduate students doing a literature review is probably a worthy read.
Oh, sorry, I did not mean to offend. The politics of milk were not on my radar screen. What I found interesting was that there was more to rehydration than just water, and there were several ways to rehydrate.
No offense at all. It’s just a fact that the milk industry has funded a lot of studies.
I think you can go a long way with household staples like sugar, salt, coffee and milk.
For what it’s worth, ‘just water’ isn’t a great way to rehydrate. You’d want, at least, some sodium with it to facilitate absorption.
So has the sugar and sodium industries. 
I did chocoblocks after a workout and gave it up eventually. I eat some crisps and humus or salsa pre-workout.
Looks like Big Water needs to pull it’s socks up, if it wants to play with the big boys!
Post ride, I’m not particularly concerned about hydration as I hydrate well during my rides. Main thing for me to facilitate recovery and adaptation is consuming some carbs and protein. I use normal foods rather than commercial concoctions.
