If I say I'm a bear, does that make me a bear?
What they call "sports karate" is essentially what most of us call American style kickboxing.
If you think about it they don't do proper Kihon or Kata, they don't wear gi's, and their competition format is essentially Kickboxing with the long pants and no low-kicks.
My friends trains and competes in that format in the UK and they call it Kickboxing not Sports Karate.
Look at those below videos of Michael Page in those competitions and tell me if as a Karateka you consider that "sports karate". For me "sports Karate" is the WKF type of competitions.
WAKO stands for The World Association of Kickboxing Organisations by the way.
