Running, why is the man faster than the woman?
In running competitions, whether the course is more or less long, it is common to see a man cut first the goal than a woman. The opposite may also happen, of course, but the tendency is for them to be the fastest to run ... but why?
The high amount of testosterone in men (20 times greater than in women) causes them to have a greater physical and respiratory resistance, two factors that determine the running. And all in the hale of the hormone's ability to create new cells in the blood, keeping bones and muscles stronger (and in greater numbers, since men have higher muscle mass than women).
Continuing on the sex hormones, in addition to the women having less testosterone, have more estrogen, hormone that promotes a greater accumulation of fat.
The body constitution of men and women is also different, and they have about 80% muscle in the leg while they have only 60%, noting that in addition to having more muscle, men have even more muscle fibers, which allows better recovery and sprinting more effectively.
Even with regard to the body, men have larger lungs and, therefore, consume larger amounts of oxygen. The heart in the male is also larger and, therefore, there is a better blood flow.
Women are always at a disadvantage in a running because they also have lower levels of hemoglobin, the protein that is present in red blood cells and carries oxygen to body tissues.
