Boxing, judo, taekwondo and karate are Olympic sports but aren't on here. But eSports and winged suit flying is? Bizarre choices of sports.
Suggest the above plus Kickboxing, kung-fu, Jujitsu, jeet kun do.
What metrics would be interesting for you?
Should a boxer wear a watching during the sparring? Is it convenient or even allowed by rules?
