How reliable is finger length in issues of athletic ability? Another experiment with five athletes: all 100 meters specialists… the outcome is again rather remarkable!
VIDEO SUMMARY (TRANSLATED):
This video – broadcasted in Spanish language – includes e.g. scenes from Discovery Channel. Professor John T. Manning explains how finger length is related to athletic ability. Finger length ratios are established in utero under the influence of testosterone. Testosterone plays an important role in the early development of the heart and lungs – the ‘motor’ of every athlete! But it is very hard to say how much in utero testosterone is involved in the early development of individuals. However, the 2D:4D finger length provides an indication for the amount of in utero testosterone.
In the second half of this video Mannings describes that the five athletes all must have had large amounts of testosterone during their early development in the whomb – because their ‘2D:4D finger ratio’ is rather low (for males). But in only one athlete the ‘2D:4D finger ratio’ is exceptionally low – and Manning explains why he expects that this athlete (no.5) has the best chance to win the race.
Then the moment of truth arrives… the athletes are prepairing to start the race. Who will win? The movie shows clearly that athlete no.5 was by far able to make the fastest start… during the race athlete no.2 becomes very competing… but at the finish athlete no.5 is still ahead, and wins the race. Manning made the right prediction!
At the end of the video Manning explains his prediction again, but he also points out that the proceses in the womb do not explain everything.
Feel free to watch the video again – knowing the succesfull outcome of the experiment should make you enjoy watching this video, and it should be easy to remember the outcome again!!!

How to measure the ‘digit ratio’? (= 2D:4D finger ratio) – Measure from the crease at the base of the finger to the tip. Divide the number from the index finger (2D) and divide it by the number from the ring finger (4D).
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:
“… 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!!!

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.
