Do You Have The Aptitude For Sports?

Do You Have The Aptitude For Sports?

Have you ever wondered why the Jamaican sprinters dominated the 2008 Olympics? Paradoxically, it could be due to their “finger ratio” known as the second-to-fourth digit ratio (2D:4D). Is your ring finger longer than your index finger? If it is, then you may have the potential to excel in sports.

The 2D:4D digit ratio is sexually dimorphic. It is affected by the prenatal exposure to testosterone and is predetermined within the 14th week of pregnancy. To calculate, you simply measure the length of index finger and ring finger of the right hand, and divide the former by the latter.

Several studies conducted by researcher, John Manning have elucidated that prenatal exposure to testosterone promotes the growth of ring finger while prenatal exposure to oestrogen promotes the growth of index finger. Digit ratio varies among ethnic groups and genders. Caucasians tend to have high 2D:4D, while black and East Asian people tend to have low 2D:4D. The average digit ratio for a Caucasian male and female is 0.98 and 1.0 respectively.

Usain Bolt (male world record holder for 100m and 200m ) is a classic exemplar of a low digit ratio. A more detailed analysis indicates that the 2D:4D ratio of Usain Bolt’s right hand could be close to 0.93 – which is quite low for an average man.

The best female sprinters from Jamaica also appear to have the long ring finger!

However, no need to give up sports if you have a high digit ratio. A lot still boils down to old fashion hard work. In my opinion, nothing bests a good proper training programme and a tenacity to not only achieve but also stick with it when the going gets tough.

So are you a covert superstar athlete?
