Not really. Everyone can have different amount of muscles due to their heredity. Such as small muscles in their face to control winking, eyebrow movement, ect...
If you were thinking along the lines of extra major muscles then no. Different races have different body structures and muscle types. Some may have different amounts red muscles and white muscles due to their race which would account for differences in physical abilities
While there can be differences in the distribution of muscle mass that can be characteristic of different races, ALL people have the same muscle groups located in the same places of the body. The differences tend to be in the genetic potential for muscle development in different areas, but environmental factors are often needed to make these differences apparant (eg: African people can have the potential to develop more muscle mass in their legs compared to Scandinavian people, if they work out).
The cells in our bodies that are responsible for skin color are called melanocytes and they are found only in the skin. The cells in the body that are responsible for muscle development are called myocytes, or muscle cells, and they are only found in muscle tissue. So the two of them are unrelated. So the answer is: No.
Plus: There is no scientific basis for any discussion about the differences between "black people" and "white people" because the real test for any differences between different populations of people should focus on blood type and not skin color. And all blood types are present in all the human races. So we humans are more the same as each other, than we are different from each other.
apparently they have higher muscle density than everyone including whites (in general). according to my friend who read an article from UC Davis. as much as 4 times.
Not necessarily. Most Negro's have a metabolism that works faster than that of Caucasians, which allows their bodies to burn fat and build muscle at a faster rate.
No.
because they have extra muscles in there legs
no every human has two sets of butt muscles the glutinous maximus and the glutinous minimus.
because they have extra muscles in there legs
No.
Glycogen is the molecule used to store extra glucose into a MAMMAL'S muscles.
The muscles would provide the extra effort because the muscles are like extra foundations moving your body around.
yes
No, there are rumours about this but it is utter rubbish!
glycogen
Under Armour ColdGear clothing provides that extra squeeze to enhance your muscles. It improves circulation to your muscles and gives you an extra edge during athletic performances.
Not that I know of. I believe mean and women have all the same muscles, except for the reproductive system muscles.
Eating extra protein does not build muscles; only strength training, combined with adequate protein, can build muscles.
