Who are stronger in nature the black Africans or the Siberian Tartars ?

I heard that the strongest human bodies are that of the Tartaric race ( Mongols , Kazakhstan , Afghanistan , ) rather than the Africans . Is that true ?? Cuz I've been hearing rumors about the Mongols , the huns , and Gog and Magog who once defeated the world . Even Great Britain couldn't colonize these regions because of it's people .
