samurai, the gravity at the poles and equator is the same, its just the centripetal acceleration that means the person at the equator has a slightly smaller reaction force (eg: a person stands on a set of scales, the scales will read higher at the poles).
Nope, it’s not.
If someone lives all their life at the pole, then even if the effect is tony, everytime they pick something up, they have to work that little bit harder so by the time they reach 30, they’ll be that much stronger.
Someone on the equator is further away from the apparent centre of mass of the earth (because the earth bluges on the equator due to those same rotational forces) and therefore experiences a smaller gravitational pull than they guy at the pole.
I reckon if the muscular eskimos all turned up at Singapore and started kicking off, the locals would have an awful time dealing with them and would need to import some Aussies or someone to deal with it all.
Or Lee Majors.
