Race and Genetics(2)

When it comes to Olympic weight lifting , East Asians tend to dominate the sport.

majority of weight lifters are from East China and there are 3 main reasons:

•Asian are the most Endomorphic group of people out of all humans, this is very very advantages for powerlifting . Asians also have shorter limbs that gives them better leverage. 

Shorter levers=More power output

also shorter limbs means lower center of gravity, this is very advantages for weight lifting. The average height of a Chinese weight lifter are ranging from 5'3 to 5'7.

West African Descendants dominate alot of power sports and event.

Example: Sprinting,Basketball,American football, Boxing and MMA.

They also dominate sports like vertical jump and bodybuilding. 

There are  few reasons and 1 myth.

Firstly, let's knock out the myth  selective breeding during slavery is not the reason at all.

By slavery I'm referring to American slavery. There was Slavery on the continent of Africa too. That was Done by the Deutsch,French,British, Portuguese and Belgians.

The fact that work improves their endurance is a lie,Afro Caribbean and African American are not the best runner at all.

The best runner are East African who are not subjected to American slavery at all. That was West Central Africans. 

The Advantages genetics are prevalent at higher rates among  West and Central Africans who live in Africa.

In particular, Nigerians followed by Ghanaians, Cameroonians. the reasons for their Advantages in certain sports are Not characteristics that a slave master could pick out.

The myth that the best were chosen  from the villages and tribes and sold as slaves is just that a myth. 

Despite the representation in sport,the most favorable genetics for the sports mentioned eariler,  are actually more frequent in Africa, where not as many people were subjected to slavery .

Anatomy 

West Africans are the most mesomorphic group people on the planet  so they are very prone to get on muscle,  they are very narrow built and narrow waist. They don't have a broad shoulders, which is why they don't perform as well in swimming because if a lack of mobility. 

They also have longer limbs and shorter torso, a shorter torso helps losing heat while living in a hot climate, this lead to a higher center if gravity.  this is very optimal for running  but not for powerlifting and strong man.

They have a longer Achilles tendon and shorter claves, this is very Advantages for sprinting and jumping.

Fast twitch muscle Fibers

West African have less red blood cells  and lower haemoglobin. as a result  of less red blood cells, West Africans have less slow twitch muscle fibers . that's coz this type of muscle Fibers needs red blood cells of respiration. 

therefore, they have more fast twitch muscles . Fast twitch muscle Fibers do not need much oxygen, therefore don't need red blood cells, this in turns gives Advantages to sports that require speed and power. as fast twitch muscle are your bigger muscle for it to grow. 

ACTN3 (Speed Gene)

In Asian, 25% have the RR Genotype, that being the best genotype for power.50% have the RX genotype,  that being good for power, not as good as the RR genotype but still pretty good. 25% have the XX genotype  they being the bad for power.

In European, 33% have the RR genotype. 49% RX genotype and 18% have the XX genotype. The R allele is more prevalent in Russians. this is pretty interesting to look at their amazing feat, calisthetic and wrestling along with other eastern europeans.

With black people is quite the shift ,with West African living in Jamaica and United States.  68% have the RR Genotype, 29% have the RX genotype and 3% have the XX genotype. 

This drastic changes indicate why there's higher percentage of powerful athletes in this ethnicity.
