In the swimming group, 17 patients were schoolchildren
aged > 6 < 10; 8 were teenagers aged ≥ 10 < 15; and 5
were 15 years old or older. Table 2 shows a comparison of
pre-study anthropometric parameters, FEV1, and PC20 for the
61 asthmatic participants of both groups. Age of asthmatic
patients in the swimming group ranged from 6 to 18 years
(mean ± standard deviation, 10.35±3.13).
