The effect of walking on peak expiratory flow rate (PEFR) of four asthmatic children is reported. Subjects 1 and 2 exercised three days per week and Subjects 3 and 4 exercised two days per week during this 9-mo. study. Subjects 1 and 3 exercised for 10 wk., did not exercise for 11 wk., and exercised again for 11 wk. Subjects 2 and 4 did not exercise for 10 wk., exercised for 11 wk., and again did not exercise for 11 wk. Subjects 1, 2, and 4 had a higher mean PEFR during exercise than during no exercise, and Subject 3 had a lower mean PEFR during exercise than during no exercise. These results suggest that walking may positively influence PEFR of selected asthmatic children if factors such as environment, allergies, and medication side-effects can be controlled.
报告了步行对四名哮喘儿童呼气峰值流速（PEFR）的影响。在这项为期9个月的研究中，受试者1和2每周锻炼三天，受试者3和4每周锻炼两天。受试者1和3锻炼10周，休息11周，然后再锻炼11周。受试者2和4休息10周，锻炼11周，然后再休息11周。受试者1、2和4在锻炼期间的平均PEFR高于不锻炼期间，而受试者3在锻炼期间的平均PEFR低于不锻炼期间。这些结果表明，如果环境、过敏和药物副作用等因素能够得到控制，步行可能会对部分哮喘儿童的PEFR产生积极影响。
