I find it super interesting when a new efficient technique breaks into professional sports. As it is described in the article, there is always push back from the establishment, with even accusations that the new technique is cheating, then in some cases the rules are changed to ban the new technique and in some cases the technique makes its way into mainstream. Some interesting examples from the top of my head:

- V-style in ski jumping: when it appeared in professional ski jumping in the 80s it was considered inappropriate by judges, and athletes had to avoid it to not be penalized with low style points. But at some point in the 90s it became so much superior in distances achieved that athletes started winning with that even after penalties, so it became recognized as valid by judges and took over. https://en.wikipedia.org/wiki/Ski_jumping_techniques#V-style

- Fosbury flop in high jump: this one didn't receive much push back, it was kind of a Columbus egg, once Dick Fosbury won the gold in the 1968 Mexico Olympics, it spread quickly and in no time all major athletes were using the technique. https://en.wikipedia.org/wiki/Fosbury_flop

- front flip on long jump: this one was quickly banned from competition, due to safety concerns. It is theoretically more mechanically efficient and has potential to produce longer jumps, but since it was never allowed to be perfected in high level competition we will never know how far it could go. https://en.wikipedia.org/wiki/Long_jump#Action_in_the_air_an...

- dunking free throws in basketball: this is other one that was quickly banned. Once a young Wilt Chamberlain demonstrated he could in fact dunk from behind the free throw line in a low league sort-of demonstration game, a rule banning it was created in the low leagues, and when Chamberlain made into the NBA the rule soon followed. https://www.sbnation.com/2022/3/26/22996516/wilt-chamberlain...
