But once puberty hits everything changes. My teenage daughter played travel club volleyball on a pretty good team, and during practice they would occasionally run drills with the boys team. Even at that age the difference in hitting power and vertical was enormous, and those differences only grow larger with age. Men and women are literally playing different games. Beyond just fairness, forcing girls to compete against biological males becomes a safety risk due to concussions from taking a ball to the head.
I think male female trans etc . can compete if analysed by sports branch basis. Male x female in contact sports like karate boxing taekwondo is not fair. However i think the difference is negligible in shooting, archerty, curling etc.
“Women tend to have thinner skulls than men, along with smaller neck muscles, which can predispose female athletes to getting a concussion,” says Sarah Menacho, MD, a neurosurgeon and neurocritical care specialist at University of Utah Health. “Data shows that women are also more likely than men to report concussion-related symptoms, and these symptoms can persist for a longer time period prior to recovery than in male athletes.”
