It is understood that the muscle weight per cubic centimeter of white people is 1.05g, black people are 1. 13g, and yellow people are in between. Smaller density, more fat and bigger breasts make white athletes almost natural torpedoes.
This makes blacks have to make more efforts than whites to solve the problem of sinking into the water. In addition, the proportion of black bone is 5%~ 10% higher than that of white bone. Black people's heavier bones and less fat make them less buoyant in water, so it is difficult for most black people to make great achievements in swimming competitions.
But this is only a common phenomenon, and there are some exceptions. According to the above comparison, the muscle density of blacks is higher than that of whites.
Should the density of yellow people be higher than that of white people? First of all, the white skeleton is big and thick. The fat content should be higher than that of the yellow race, right? Besides, they live in high latitudes, have strong genes, and are much better than us because of their acquired environment, diet and fitness hobbies.
Even though we can't compete with them in size, several world weightlifting champions are all black and white, which shows that we yellow people are no less powerful than them under the same body weight.
According to the above, I think the muscle density of yellow people is greater than that of white people.
