The Colorado Asthma Ski Day an annual cross-country and alpine skiing
event, encourages children with asthma to participate fully in outdoor
winter sports. Since cold air and exercise can trigger bronchospasm,
we examined the peak expiratory flow rates of 80 children who attended
Asthma Ski Day 1992 or Asthma Ski Day 1993 to establish a safety prof
ile for this event. Peak expiratory flow rates were measured prior to
skiing, at lunchtime, and at the end of the day's activities. We asked
the children to pretreat with their regular medications, as prescribe
d by their physicians, to use their bronchodilator inhalers p.r.n., an
d to report to our medical station if an episode of acute asthma occur
red. The average age of the participants was 9.5 years, and the averag
e baseline daytime peak flow rate was 100.03% of predicted The average
percent change in peak flow rates during the day was an increase of 5
.00%. Our results demonstrate that with medical supervision, peak expi
ratory flow rate monitoring, and properly administered medications, pe
ak flow rates can be stabilized and even improve during cold-weather e
xercise to an extent that safety concerns need not restrict children w
ith asthma from engaging in exercise or cold-weather sports. The Color
ado Asthma Ski Day can serve as a model event for other organizations
that want to promote outdoor activities for children with asthma.
