The pulse-rate prior to the race showed more uniformity among the boys when the
rates lay between 88-108 as against the girls 88-124. In only 4 of the boys was
the pulse-rate 100 or more, while 9 girls showed a high rate. Excitement largely
accounts for this all-round increase of pulse-rate, and the comparatively higher rates
in the girls indicates a relatively higher susceptibility to the effects of excitement
in them. There is normally a definite physiological increase of pulse-rate in pubescent
girls, so that the normal rate may be somewhere near 100, which, of course, does not
account for the high rates seen here.
This higher susceptibility to the effects of excitement in girls seems to be borne
out by the fact the average rise in rates following the races is lower in girls (47.5) than
is the average rise in boys' pulse rates (51). If anything, this indicates that the
reserve forces of the heart have already been called into action prior to the actual
contest, a surmise which is proved by the average slower rate of fall (32) in the girls than
in the boys (36.7) two minutes after the race, thus exemplifying the physiological
law that the greater the fatigue of any organ, the longer time such organ takes to
recuperate. In one girl's case, M. G. (2), the pulse-rate was 140 five minutes after
the termination of the race. She appeared to be cold and was shivering, and was
really the only child seen who perhaps was not suited by build or nature to take
part in such a contest, although no harm came to her, for she was seen some time
afterwards and was then warm and happy.
A very interesting result was the high jump of the pulse-rate in the three girls
of poor circulation, L. H. (60), G. T. (60), and M. G. (52), and in the high jump of
