In this time period, aimed at this audience, I'm guessing it'll continue depicting the matches as shoot fights, even if they explore some of the more realistic backstage dealings and training.
Kayfabe, or the whole song and dance that pro wrestling is real fighting, could be a very sensitive topic in those days. Pro wrestlers didn't want to be seen as fake, and in Japan, they went to lengths like implementing "strong style" where the strikes and holds could be super stiff to the point where wrestlers were practically beating each other up every night. Either this manga is respecting kayfabe (to an extent), or having the matches as shoots works better for them stylistically or in terms of narrative. My take on it, anyway.
In any case, it's an excuse for me to post this ol' gif
