I found this interesting Wrestling scene in episode 135 (2001).
Martin Krahn as Max on the left in longer blue shorts, and I think Martin Mitdank as Carlo in yellow shiny shorts. Look both like Basketball shorts. Some spectators in the background, I think a boy in red and some girls in blue shorts, but not sure if shiny.
I still have to recheck some other episodes including swimming scenes.
