Huh? What? Oh, that was the “no, that’s wrong” buzzer going off….
The frequency of this gene is nowhere high enough in any population to be a “racial” trait, even if such traits actually existed. And it is prevalent mainly among Europeans and Asians. The slow ones have the fast genes.
Back to the paper:
The frequency of the 577X null allele differs between human groups: it is approx 10% in Africans but approaches 50% in Eurasian populations. Two independent studies have reported associations between R577X and elite athlete status; the frequency of the 577XX null genotype is lower in sprinting and power athletes and higher in endurance athletes.

The data suggest that the genes most studied and associated with performance in aerobic endurance running (ACE and ACTN3) do not seem to fully explain the success of these athletes. It seems unlikely that Africa is producing unique genotypes that cannot be found in other parts of the world. So far, the evidence shows that the subjects’ phenotype (molded over time by several factors) seems to have greater influence than their genotype in their long-distance running success.4 While recognizing that this field of study is at an early stage of understanding, the available results show that the identified candidate genes for human performance neither determine nor exclude the possibility of athletic success. Although, the right choice of parents can help in the search for athletic success, this is not the deciding factor between success and failure in sport.4

AS I STATED BACK TO THE CASE STUDY QUESTIONS, CHAMPS FROM the 1900 to 50s, Brazil , Cuba and of course why the non diluted WEST AFRICAN BORN & BRED isnt a factor !
