Obviously this won’t work for all sports, but things like football, track, soccer, it would allow for de-gendered team, even allowing athletes with the skills but not the genetically-endowed physical attributes to have a place to play.
Note: I know very little about sports and being on a sports team, so please point out anything that doesn’t make sense.
Because a man tends to be stronger, faster, and more athletic than a woman of the same weight. It won’t work for football, track, or soccer.
It would work for marathons though. Figure that out
Testosterone also increases red blood cell count, so even male endurance athletes have an advantage. Look at Tigst Assefa who holds the women’s World record for a marathon at 2:11, she’s 120 lbs, the top 5 male marathon runners are all at 120 lbs too and run 10 minutes faster.
