Er hätte seine Aussage noch mit der Benennung einer Studie belegen können, sofern es eine gibt, denn so steht die erstmal im Raum ohne Beweise (also, dass Menschen mit afrikanischen Einflüssen biologische/physiologische Vorteile haben).

Könnte auch schwerfallen so eine Studie neueren Datums zu finden, flüchtige Suche bei Pubmed ergibt eher, dass diese früher gehegte Vermutung nicht aufrecht erhalten werden kann

A growing body of evidence suggests that genetic variation does influence athletic performance, yet despite the speculation that African athletes have a genetic advantage for physical performance, there is no genetic evidence to suggest that this is the case. The only available genetic studies of elite African athletes do not find that these athletes possess a unique genetic makeup; rather, they serve to highlight the high degree of genetic diversity in east African populations and also among elite east African 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
