, Eddie Crawford of the University of Glasgow took a careful look at the
effects of weekly mileage, training intensity, paternal age, occupation, and
competitive performance on offspring gender in 139 male runners ('Sex Ratio
of the Children of Male Distance Runners,' Thesis, Institute of Physiology,
University of Glasgow, 1992). Crawford became interested in the topic when
a survey appearing in the publication Scotland's Runner revealed that just
23 per cent of the children fathered by runners engaged in serious training
were boys. |

发帖数: 18660 | 11 Crawford divided his athletes into several categories, including (1)
individuals who were not actually training at the time they and their mates
conceived a child, (2) subjects who were running between 0 and 30 miles per
week when their partners became pregnant, and (3) runners who were training
between 30 to 50 miles per week. To these runners, a total of 377 children
were born (about 3.4 per man).
Not running at all - or running less than 30 miles per week - proved to be a
good way to increase one's chances of having a male offspring. Overall,
about 62 per cent of the children of runners who were taking a break from
training or who were running fewer than 30 weekly miles were male.
However, things changed drastically when weekly mileage soared above 30
miles per week. For those runners who ran between 30 and 50 weekly miles,
only 40 per cent of the offspring were gentlemen! According to Crawford,
such high-volume running tends to produce dips in testosterone, which in
turn produces a decline in the output of boys.
Mileage proved to be the only factor which had an impact on offspring gender
, as running intensity (average training speed), overall life stress,
paternal age, social status, manual vs. non-manual labour, competitive
success, and the time interval between marriage and conception all had no
significant effect.
Yet to be reckoned in the sexual-determination story is the role played by
the training mileage of the mother. In theory, higher mileage levels should
drive female sex-hormone concentrations downward, increasing the chances of
having a female. Thus, married couples training together for a marathon and
also trying to have a child should have inordinate numbers of female
offspring. Conversely, such couples ambling for just 15 to 20 miles per week
can look forward with some confidence to boys.
