i've done several types of martials including muy thai, bjj, tkd, fma, etc... haven't competed formally in decades (eg. in tkd as a kid), but sparring in class is still a battle, and sometimes more stressful than a formal tourney (as you're fighting to improve or keep your unwritten "spot on the totem pole"' amongst training partners you will see daily).
it is important to have a "never give up" attitude, but it's important to stay calm but still at a highly energized level of alertness.
fighting, like tennis, still requires alot of focus on gathering data about my opponent, strategizing, and of course, executing (explosively) on my side... and having that awareness requires me to be mentally calm.
that said, in both fighting&tennis, how do you stay calm when a ball or punch/kick is coming at me faster than i'm comfortable with... practice
nothing magical about that... no matter how calm or frenetic, it's hard to execute in a reactive state
moratoglu's philosophy reminds me of saenchai... one of my favorite muy thai guys i love watching.... he's so calm&relaxed... looks like he's having alot of fun in the ring... yet when it's time to act, he does so with such smooth timing (he doesn't strike me as particularly or extaordinarily explosive (compared to his opponents)... mostly superb timing... which i imagine (from my own experience) requires a calm/clear mind):
i think his "fighting style" is what i'd want to emulate, but i imagine it required tens of thousands if not millions of reps to attaing that level of smooth-fighting.
in the boxing world... lomachenko is one of my fave examples of a "smooth" fighting style:
perhaps comparable in the tennis world is someone like fed, who always comes to mind as someone that is "smooth"
but back to the fighting styles question of the OP... when i think of a fighting style that is "energetic and aggressive"... i immediately think of guys like tyson & nadal (who is my fave), who seem to rely more on raw aggression to overwhelm opponents.
i used to be in the mindset of fight fight fight, aggression, never give up, etc... more like nadal, grind you down through attrition... but as i get wiser, or maybe just older (eg. not as fit as my 20-self).... my mindset is more deliberate... and i'm trying to be smoother, more precise and deliberate with what i'm trying to do with every shot (but hopefully not losing the never give up attitude, still trying to be explosive moving to contact and through execution)
