So, would you recommend having a glass of it after every workout, or only after particularly intense ones, like a long run, or after deadlifts?
These articles should answer your question.

"High-quality protein dosed at 0.4–0.5 g/kg of LBM at both pre- and post-exercise is a simple, relatively fail-safe general guideline that reflects the current evidence showing a maximal acute anabolic effect of 20–40 g. For example, someone with 70 kg of LBM would consume roughly 28–35 g protein in both the pre- and post exercise meal. Exceeding this would be have minimal detriment if any, whereas significantly under-shooting or neglecting it altogether would not maximize the anabolic response."
Personally, I'm finding that having carbs and protein immediately after any workout to be helpful for me. Otherwise, I feel a bit hungry and run down. I have to eat eventually anyway, so I might as well eat when it might be physiologically advantageous. I've tried eating before exercising, but that makes me burp, and that's not good while swimming.
I'd be concerned about injuries when people engage in agility sports, specifically lateral movement, particularly as people age, due to sudden acceleration/deceleration.But I would like to work in more agility stuff eventually.
