Usain Bolt, fastest man on earth, sprint talent is in his fingers!

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

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 the hands of 241 boys aged 10 to 17 who took part in a sports talent-spotting competition in Qatar. And the results pointer out that a low 2D:4D finger ratio is linked with a fast sprint!

Professor John T. Manning (a.k.a. ‘the finger professor’) about the 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 confirmed the link between finger length and sprint talent: long-distance runners have the same hand characteristics – a ‘low 2D:4D finger ratio. But to understand the implications in this perspective one should be aware that the long ring fingers has also been linked with other ‘testosterone’ related matters such as: a lower risk of heart disease and good results in exam success in mathematics, to male aggression and higher earnings at the London Stock Exchange.

So the predictive value of a long ring finger is actually pretty, and certainly not reliable in individual subjects.

Nevertheless, John T. Manning has described in his first book – ‘Digit Ratio’ – that the hands of Jamaicans are usually featured with a relatively long ring finger – which is confirmed by various hand photos of the most successful sprinters from Jamaica (see the photo below).

Researchers at the University of Cambridge found that stock traders with a lower digit ratio of 0.93, on average, earned 10 times more than those with an average ratio of 0.988.

Traders with a lower digit ratio made an average of 679,680 pounds (or about $1 million U.S.), compared with 61,320 pounds ($90,956 U.S.) by those with a higher ratio, the report said.

The research, published today in the journal Proceedings of the National Academy of Sciences (PNAS), found that individuals who were exposed to high levels of prenatal testosterone tended to be more profitable traders.

The British researchers provide the following explanation for their finger length research results:

Testosterone, a steroid hormone, surges between the 9th and 18th week of gestation, exerting powerful organizing effects on the developing body and brain. According to both animal and human studies, these effects may include increased confidence, risk-preferences and search persistence, as well as heightened vigilance and quickened reaction times.

The amount of testosterone one was exposed to in the womb can be measured because it leaves traces throughout the adult body. Measures of prenatal androgens are increasingly used by paediatricians to gauge whether a newborn has been exposed to abnormal levels of steroid. The most common measure for behavioural studies is the ratio of the index to ring finger (2D:4D) on the right hand, a relatively longer ring finger – lower 2D:4D – indicating higher prenatal testosterone levels. Males typically have ratios below 1, women above 1.

As digit ratios have been found to predict performance in competitive sports such as tennis, football, and skiing, the scientists hypothesised that 2D:4D may also influence the risk preferences and physical speed required for what is variously called noise or high-frequency. Traders engaged in high frequency trading look for fleeting price anomalies and hold their trades for minutes, sometimes mere seconds.
