. A 6‐week period of physical training of 28 asthmatic children reduced the exercise‐induced percentage fall in peak expiratory flow (from baseline) from 44±4% (mean ± SE) to 30±4%. Resting pulmonary function was unchanged. Resting and maximum heart rate (submaximal treadmill running) and postexercise plasma lactate were all lowered by training. The individual values for exercise‐induced bronchoconstriction and postexercise plasma lactate correlated positively before and after training. Furthermore, the training‐induced reduction in these parameters correlated. In 14 asthmatic children, who served as controls, exercise‐induced bronchoconstriction and physical fitness remained unchanged during a comparable period. The study demonstrates a beneficial effect of endurance training on exercise‐induced bronchoconstriction and working capacity.
