The athlete on the right looks to be carrying Gene's from the neanderthal genus.
All non-sub-Saharan Africans have partial neanderthal ancestry. I believe the highest concentration of Neanderthal ancestry was in Tuscany, Italy.
What I think happens with some people - and some animals, such as bears - is that the small percentage of ancient genes they have end up dominating the phenotype of the organism in certain cases. So you will have these rare massive bears appear from time to time, because they have small amounts of ancient genes from giant bears in their evolutionary origin of ancestry / family tree, which show up in some random bear born today in modern times.
I think the same goes for people, where you see some people looking very much Neanderthal, even though they have the same 2.5% neanderthal DNA as most other White people do [or Asians, although I don't know what the specific average amount of neanderthal DNA is for White people and Asians, etc - all I know is that all non-sub-Saharan African people have some percentage of Neanderthal DNA in their overall DNA profile].
It's funny how for years we said that "race does not exist", yet in 2010, it was determined that all non-Sub-Saharan African people have partial neanderthal ancestry, whereas sub-Saharan Africans have no Neanderthal DNA.
So not only do sub-Saharan Africans and White people or Asians, etc, have different genetics in terms of the clustering pattern of micro-satellite alleles [which can identify beyond any doubt, literally with 100% accuracy, what race a person is from a blood sample in a double-blind scientific study/test, based on the clustering patterns of those micro-satellite alleles], we now have evidence that White people have a percentage of another SPECIES of bipedal hominid in our genetics, and yet people STILL say that race doesn't exist?
LOL.
This may also explain why Whites and Asians dominate strength sports - as neanderthals were much stronger than humans, quite possibly with female neanderthals being as strong as human males. That may explain the strength advantage for Whites and Asians, and why Whites and Asians dominate powerlifting, strongman, and Olympic lifting [not without exception - as I realize there are many extremely talented Black strength athletes - but not nearly as many as Whites, for example, no matter how you look at that data].
But no - we can't say that.
We can't even say that West African Blacks have an advantage in sprinting, or that Blacks dominate in basketball, football [aside from the quarterback position], or other sports, or that Blacks have average penis lengths longer than do Whites, who in turn have average penis lengths longer than do Asians, even though a global penis size chart was released in 2010 which proved this.
We can't stand facts about racial differences, because those facts are "racist".

It's better to say nothing than to engage in science while studying these things. After all, all of the above is just an example of "scientific racism" - when the truth offends people by proving there are average differences between the races [and these differences extend to literally 60 different traits, including the frequency of conceiving and producing/birthing twins, with Blacks producing more twins than Whites do, who additionally produce more twins than Asians do].
It's much better to just ignore facts when they are inconvenient to people who lie and claim that all people and all races are exactly equal - literally the equivalent of all people in the world being identical twins on the aggregate with "blank slates" for IQ/intelligence potential, and other traits - even though all scientific and empirical evidence found by liberal/leftist scientists in academia who study these things for a living shows that is not the case.
Who needs facts and data, when we can have emotion and outrage instead?
