>Perhaps the best physical test for innate athletic ability is the standing vertical jump. There isn't an awful lot you can do to improve it.

This isn't a very good example, because the reason it gets harder is that increasing the body's muscle mass also increases the strength needed to propel it a certain distance. Hence gaining muscle mass both helps and hurts the vertical jump. Is there any reason to believe intelligence should be like this?

No, it's not a measure of strength. It's a measure of explosiveness, or rate of force production. They are actually very different physical traits. Strength can be trained to a large extent. Explosiveness is mainly genetics. You can improve it by 15 or 20%. That's it.
