Females run faster than males

Posted by iluvshrutiverma on December 14, 2009

Males as well as females think that males are physically stronger than females. I have been looking for data to substantiate that claim.

Females outlive men by 5 – 7 years everywhere in the world, so I tend to believe that females are physically superior species.

I told this to a friend but he was not convinced. He insisted that males are stronger and females are weaker. I asked him whether there is any data he can provide in support of his belief. He said – look at the 100m Olympic race, males invariably run faster than females.

I remembered that the men’s world record for 100m was somewhere around 9.5 seconds and the women’s world record was somewhere around 10.5 seconds. So, at first he seemed to be correct.

But then I decided to take a closer look, and this is what I did: I pulled gender-wise data from Wikipedia for World Athletics Records. Following table summarizes the data available.

WR stands for World Record.

WR(f) = WR time taken by a female to complete the race

WR(m) = WR time taken by a male to complete the race

Next I plotted them on a Chart, added a simple trend-line to the data points, here is what I get:

Here is my interpretation of this trend: For short distances, females on an average take 1.12 times the amount of time taken by males for the same distance, but as the distance goes on increasing the time taken by them as compared to the time taken by males goes on increasing. So much so, that the factor reduces to less than 1.06 for 100 kms race.

So, does this mean that if there were races longer than 100kms females would be beating males? Well, perhaps – Yes. Extrapolating the same trend line, we see that if there was a race of 209.5 km, females and males would have completed it in equal time. For any race longer than 209.5 km, females would be scoring a better timing as compared to males.

We all know that life is a long race, and therefore females beat men at life expectancy. They live 7 years longer to males. So next time do not think females are weak, because they are not!
