Wanted to add this little clip from Homo Optimus as an addition to my comment regarding DOMS.
Did you try to recommend the optimal diet for the sports people?
I did indeed. There is a leading football team in Poland for the players of which, some time ago, I recommended correct nutrition. They are resistant to fatigue, play aggressively, and typically score goals in the second half when their opposition is falling apart. And one more important detail – they do not have muscle cramps, and suffer injuries much less often than other players.
Not sure how well the Polish team referenced here play or which one it is; more interested in the lack of muscle cramps.
