Sporting aspirations at the elite level is generally an illusion unless the parents are also at elite level. Last time I looked at studies, the average sport is around 75-99% determined by genetics when it comes to the top elite in those sports. World champions has to first win the genetic lottery, and then do the hard work to even have a chance to win. This is why its fairly common to see top elite sport players having parents, siblings or children that is also at similar elite level. The big difference with gender is that we can easily those genetics. It is much harder to look at two women or two men and measure their blood oxygen maximums. It is generally trivial to get an idea of blood oxygen maximum if one person is a man and the other is a woman.
