there is no way that I can quote you...
A few points. First of all, my statistics. It is perfectly valid. Your point is Chinese athletes are genetically at a disadvantage in certain sports because they lack athletes in certain height and weight categories. I show you that the Chinese athletes have the same height and weight as other nations.
Ohhh, that's what you were getting at? No, you're still wrong. For example, Russia can field an athlete in the super heavyweight division, and China can field one too. But Russia picked him out of 50 guys while China only had 5 to pick from. So while we both put a guy up there who weighs about the same, our Chinese guy is a lot less talented because he was picked out of a smaller talent pool. That's why we have never beaten Russia at the Super heavies. It's not because we couldn't even get a guy to go up there.
About sickle-cell disease. It was my attempt to illustrate a potential difference in one physiological feature does not give you the ultimate advantage in a sporting activity. We only see the most obvious things, such as big muscles. what we don't know is that many other features will need to coordinate to achieve a final outcome. My example of sickle-cell disease was aimed to show you that a single different feature does not usually mean advantage, no matter how obvious it is.
Only one feature can't make it all with nothing else. I've already said that, but a combination can, and combinations can be passed in populations. Just like looks are a combination and those can be passed. But another point is, every advantage counts. Your sickle cell example doesn't even apply to black athletes because those athletes don't have sickle cell but they do carry the muscular advantage. Could Asians/Whites have other advantages? Of course! And that's why the races are different and have different advantages as I said.
About why white people don't run. It's not that they can't afford it. It is that they are interested in something else. they grow up doing the activities that they do, like tennis, golf and rugby. That has become a habit. And when some of them become good at some of these activities, they focus on them and become an athlete. It is similar with rugby. Since black athletes are so good at football, why don't they participate rugby? they grow up playing football. And that's what they have been accustomed to.
Definitely a factor, but as I said, not enough to make it so that every winning sprinter is black; every sprinter who made it to the finals is black. If 70% were black, then maybe, just maybe, but 100%? You're telling me that even though all races are even, that no other race, no whites, no Asians, anywhere in the world, was interested in training for that 100m medal? Only blacks wanted it and trained for it? Every year? (Even though their muscles made them more tired? LOLOL) Su Bingtian didn't win cus he didn't want the gold enough to train for it? Come on come on. Is there even a point to this conversation? You're killing yourself.
And I don't know where to get the numbers from, but I have a feeling that of all the sprinting applications to the US team every year, a large percentage are white. We just don't hear of them because they don't win.
