Sumo wrestlers : they ’re huge . The huger the better . remnant of story , correct ?
Of course not — sumo wrestlers practice nonindulgent training including a peculiar diet and they even go in sumo communes called “ heya . ” But one affair that scientific discipline has find to make a good sumo , and something the athletes regrettably do n’t have control over , is the duration of their fingers . Specifically , the proportion of the lengths of their pack to exponent finger’s breadth .
You ’ve all heard about the digit ratio affair right ? It seems to come up in bars as a dalliance mechanism , but drunken flirters lean to expend the wrong finger or the amiss proportion . Here ’s a simplified account : if your ring digit is prospicient than your index finger’s breadth , you were exposed to more testosterone in the womb than if your power finger is longer , in which compositor’s case you were probably scupper to more oestrogen . Women lean to fall into the latter category , men the former , although ratio vary widely . Mine seem to be almost the same . In the film below , the band finger is longer , so the ratio is low , which indicates mellow testosterone exposure in the womb .
Scientists have studied the so - called 2D:4D ( d is for digit ) proportion as it relates tosperm tally , penis size(“under anaesthesia , flabby and stretched penile lengths were appraise , ” not kidding),eating disorders , handwriting , financial trading , melodious power , just to name a few . The list is long . Maybe sumo rassling was the only thing leave behind ?
conveniently , thesumo museum in Japancollects wrestlers ’ handprints . So Tamiya et al , who published their oeuvre in the October 10 issue ofEvolution and Human Behavior , examined some of those handprints and come up that a lower 2D:4D proportion in sumo wrestler was relate with “ high sumo social station and better winning records . ” But the tie was not as strong as with other sports like association football and skiing , so the authors hypothecate that testosterone exposure in the uterus is more important for athletes that call for survival rather than those who wish sumos require volatile power .
