(SALT LAKE CITY) -- Do men punch harder when standing up or when on their hands and knees? The author of a new study out of the University of Utah found that male boxers and martial arts practitioners punch twice as hard when standing up as when kneeling, and more than twice as hard when punching downward compared to punching in an upward direction.
So why do the experiment? The author believes that the ability to punch harder in a downward motion while standing up provided a survival and mate-selection advantage that contributed to the evolution of bipedalism, or the act of walking on two legs in humans.
“The results of this study are consistent with the hypothesis that our ancestors adopted bipedal posture so that males would be better at beating and killing each other when competing for females,” the author explains, noting that “it provides a functional explanation for why women find tall men attractive.”
The researcher’s findings were published by PLoS ONE.
