What does finger length say about athletic ability? An experiment with six athletes: all 5000 meters specialists… the outcome is simply astonishing.

Professor John T. Manning explains how finger length relates to testosterone & athletic behavior.

Professor John T. Manning explains:

“… What I should be able to do is look at the differences between the ring finger and index finger, and on that basis rank these runners: first, second, third, fourth and so on. In theory that should work.”

Comment voice explains:

“In practice we’re providing professor Manning with photocopies of the athletes hands. And in return he’s risking his reputation by providing us with the results of a race that has yet to be run.”

You can take a look at the outcome of this remarkable experiment from the BBC’s “Secret of the Sexes” – surely you will enjoy it, probably you will remember the outcome easily!!!

Long ring fingers drive faster (and sprint faster!)

New research from Germany points out that men with long ring fingers may more easily drive too fast, overtake on dangerous roads, and park illegally – indicated by more (self-reported) traffic violations!

Earlier research pointed out that Jamaicans are known for having long ring fingers: a rather remarkable – speculative – story about how “the world’s fastest man” got into a car accident earlier this year (luckely Usain Bolt escaped without serious injuries).

Earlier ring finger research:

Numerous finger length studies have shown that a long ring finger compared to the index finger in men, can have a powerful effect on health & behaviour.

Quite a few studies suggest that a long ring finger is linked with: increased male aggression, outperformance in sports & (financial) risk-taking behavior.

New ring finger research from Germany:

Researchers at the University of Mainz recruited 77 male drivers at an average age of 38. Each volunteer had their left hand scanned to measure the difference in length between the ring and index fingers.

They then had to provide details of all driving offences within the previous five years. Just over a third of the drivers reported having penalty points on their licences, ranging from one to 20, for offences ranging from speeding to drink driving.

The results, published in the journal Accident Analysis and Prevention, showed men with longer ring fingers were more likely to have offended.

In a report on their findings the researchers said: ‘A longer ring finger than index finger was related to more traffic violations. Hormone exposure in the womb might increase traffic violations in later life.’

Jamaicans have the long ring finger, and… Usain Bolt has the long ring finger!!

Now, knowing that Usain Bolt has the long ring finger & with the German research findings in mind:

… You might wanna take a look at the full story of Usain Bolt’s car accident earlier this year (april, 2009):

Jamaican sprinter Usain Bolt has the long ring finger!

Usain Bolt has the long ring finger, a marker for sprint talent!

The 2008 olympics in Beijing pointed out that Jamaican sprinter Usain Bolt is the fastest man on sprint ever! And last sunday he set another new world record at the Athletics World Championships 2009 Berlin. How come that Jamaican sprinters run so fast?

Earlier this year British researchers studied 241 boys aged 10 to 17 who took part in a sports talent-spotting competition in Qatar.

Professor John T. Manning (a.k.a. ‘the finger professor’) said about the finger research:

“We found finger ratios of the right and left hand were positively linked with sprinting times in boys. The advantage they had was soon apparent after the start of the sprint and remained steady thereafter.”

Previous studies have shown long-distance runners have the same hand characteristics (low 2D:4D digit ratio). But in this perspective one should not forget that longer ring fingers have also been linked with everything from a lower risk of heart disease and exam success to male aggression and higher earnings in the workplace. So the predictive value of a long ring finger is not very specific, nor reliable in individuals.

Nevertheless, according John T. Manning it’s a hand fact that Jamaicans are known for having the long ring finger – and it’s confirmed by various hand photos of the most successful sprinters from Jamaica.
