Why the males faster than females in running?

Males are generally faster than females in running due to physiological differences, including greater muscle mass, higher levels of testosterone, and larger lung capacity, which contribute to increased strength and endurance. Additionally, men typically have a higher proportion of fast-twitch muscle fibers, which are more efficient for explosive speed. These biological factors, combined with differences in body composition and cardiovascular performance, contribute to the observed disparities in running speeds between genders.
