it really also depends on the person and their body type and how they use their body in mobility and footwork. i see people who train the same style fight move differently regarding bouncing/hopping.
there is a disconnect
between forms, solo pad/heavybag etc., drills in the air, and on to partner drills, pad/bag work with a trainer, sparring, fighting. you will see it increase from form to pad to sparring and fighting. how someone enters and exits etc.
its not the same thing in the sense that your state of being and reactionary movement/awareness arent going to be the same. like a fight isnt going to ever really look like a form.
a lot of times when people say ‘look like kungfu’ they refer to forms or movies. and no it wont look like that. BUT you will see people who fight and it will many times look like kung fu. esp if thats all they trained, you will see tendancies in things like ready stance, guard, entering/exiting, countering things like that.
but thats all in the nuances. you wont see beginners fight much different than any other beginners. thats how it is.
can you see thai boxing when its thai boxing, or how about someone who is a very advanced western boxer adapting to kickboxing but sparring hard with it, can you tell he has boxing training simply by how he fights and moves? the techniques and methods of thai boxing are so defined, prounounced, and focues that it is easy to see. but you can see the same qualities represent themselves from any style
