[DC comics] If Batman and Nightwing are examples of normal humans with physical training, rather than superpowers, what are professional sports like in DC?

In a world where people have the reactions to dodge a bullet from a gun held up to their head, is hitting a fastball in baseball trivially easy? Does basketball involve people leaping from center court to slam dunk a three pointer? Do golfers consistently get hole in ones on holes we consider a par 4?

In DC just being an olympic-level athlete is alone enough to become a costumed crimefighter. A whole lot of golden age heroes had only that, in fact it was the whole schtick for Mister Terrific. Others like Captain Steel (if memory serves me) just started like athletes, before getting some cybernetics or metahuman powers. 

I belive the sports do monitor for metagene, but otherwise being ridiculously toned or buff is fair game as long as you've reached your "peak human" normally.

While that would likely imply that tables of world records are more tight in DC Earth, just by virtue of comic version of Olympic level athletes being different from real world ones it should be balanced well enough.
