a controlled study of 20 children with asthma who participated in a 4-month running program ( 30 min/day , 3 days/wk ) , using inhalation of a beta-2 stimulant prior to each running session to prevent exercise-induced asthma , showed significant increases in work tolerance ( 120.5 +/- 45.0 w before , 131.5 +/- 43.5 w after , p = 0.002 ) and cardiopulmonary fitness ( peak oxygen consumption 37.6 +/- 8.6 ml/kg/min before , 43.1 +/- 10.5 ml/kg/min after , p less than 0.001 ) .
