Caucasians (of European Origin) dominate the big majority of events in summer Olympics and almost all Winter Olympics, because of economic factors and because they have better opportunities, i will accept that but.................
Take a look some stats here
Sprints-Almost always dominated from black athletes (who their roots come from West Africa originally )
Middle distance-Arabics and Nothern Africans
Long Distance-East Africans
Field power events as discus,shot put, javellin etc-All caucasian of eastern European ancestry
Swimming-Heavily Caucasian dominated
Gymnastics-Heavily Caucasian dominated of eastern European origin,Asians excel always as well!
Wrestling-weightlifting-Heavily Caucasian dominated
i can go on for ever,but is not all this true??
Well i can always find exceptions as Wariner or Borzpv or Menea,in running or some black swimmers etc etc but exception confirms the rule does not it?
