Do Africans build muscle faster?
No. This has been a part of a long-standing canard about Black bodies and stereotypes about our physical features for the last 500 years. Black people don't have some G-14 classified, special genes that make us build muscle any faster, denser, leaner, or superior to any other ethnic group.
Generally, muscle mass is highest in African Americans, followed by Caucasians, Hispanics, and Asians, while percent body fat is highest among Asian subjects (Wang et al., 1994; Silva et al., 2010) .
African American (AA) males and females tended to have higher values of SM mass across the lifespan, while Asian females and Hispanic males had the smaller absolute SM mass compared to the other groups (Fig. 3).

Some people have a genotype that makes them better at power or endurance. Much of this is related to muscle fiber type. If you naturally have more type I fibers, you are more likely to be good at endurance. If you have more type II, fast-twitch fibers, power is your strength.
Some people can naturally build more muscle than others (which seems totally unfair), but apparently it all comes down to hormones and genetics.
What is the strongest human race, physically? Eastern Europeans, Balts and Icelanders seem to be the strongest weightlifters and strongmen. To some extent this is probably due to them having a culture of weightlifting; the Polynesians might be even stronger genetically.
Individuals of African descent have higher bone density and fewer fractures than Caucasians, whereas Asians have lower fracture rates despite lower bone density.
“Blacks tend to have longer limbs with smaller circumferences, meaning that their centers of gravity are higher compared to whites of the same height,” Bejan said. “Asians and whites tend to have longer torsos, so their centers of gravity are lower.”

Strength peaks at age 25.
Your muscles are at their strongest when you're 25, although for the next 10 or 15 years they stay almost as hefty — and this is one of the traits that can be most easily improved, thanks to resistance exercise.
Iceland boasts of some of the strongest people in the world. With names like Jón Páll Sigmarsson, Magnús Ver Magnússon and Hafþór Júlíus Björnsson—the Mountain from Game of Thrones—Iceland has cemented itself as a veritable breeding ground for giants.
In summary, Women are the strongest between 26 and 37 years of age. Men are the strongest between 26 and 35 years of age. But of course there are individual differences between athletes and some people peak before or after that age window.
It comes down to hormones and genetics. Chances are, you've probably heard before that every body is different, and on a physiological level, that's really true. For example, some bodies are primed to put on muscle more easily than others.
Muscle-building abilities vary from person to person. That said, it's important to understand the big picture, because it doesn't begin and end with your genetics. You may have a genetic profile similar to that of an Olympic athlete, but if you don't put in the work, you'll never learn your actual potential.
Body composition differs between men and women, with women having proportionally more fat mass and men more muscle mass. Although men and women are both susceptible to obesity, health consequences differ between the sexes.

Who is the dominant race in the world?
The world's largest ethnic group is Han Chinese, with Mandarin being the world's most spoken language in terms of native speakers. The world's population is predominantly urban and suburban, and there has been significant migration toward cities and urban centres.
Although Asians have lower areal bone mineral density (aBMD, g/cm2) (by dual‐energy X‐ray absorptiometry [DXA]),(1–3) rates of hip and wrist fractures are lower among Asian compared with white adults,(1,4,5) and fracture incidence is also lower in Asian children and adolescents compared with their white peers.
Conclusions: Asians had smaller bones, thicker and denser cortices, and more plate-like trabeculae, but biomechanical estimates of bone strength did not differ between groups. Studies are needed to determine whether these differences persist later in life.
Taller subjects had greater bone mass at the radius sites than expected from their calcaneus or spine bone measurements (0.1 to 0.2 Z-score difference per 5 cm difference in height).
In 2009 Jamaican sprinter Usain Bolt set the world record in the 100-meter sprint at 9.58 seconds. For those of us more accustomed to sitting than sprinting, to translate this feat into terms of speed is to simply underscore the stunning nature of Bolt's performance.
