Why do many boxers immediately put on a shirt after the final bell? I mean, they've just been through combat and are sweating profusely. And packed arenas are always hot environments.
While the environment is warm, all that sweat and little to no movement will cause their muscles to cool too quickly which leads to sore tight cramped muscles. These guys for the most part (looking at you Andy Ruiz you fat *******) are highly over tuned machines after a fight. The amount of adrenaline, cortisol and other chemicals flowing through them only adds to the issues at hand.
I would probably guess that it will make the post fight interview more broadcast friendly as most of the time it’s first shown on morning tv and tops off doesn’t suit that audience
Your question, made me want Andy Ruiz & Chris arreola to wear shirts boxing. Biggest boobies battlin' in boxing that night. Let's hope they both manage their weight or the ring may collapse mid fight
