If Football Heads: 2019-20 Germany (Bundesliga) sends you down a curiosity rabbit hole, start here.

Archery was already on the Olympic programme in 1900, boxing joined the modern Games in 1904, and basketball became a medal sport in 1936. The details change, but the appeal of learning a system and trying again is remarkably persistent.
