To determine the effect of "warm-up" on exercise-induced asthma (EIA) 18 subjects ( mean age 19.7 years) performed five minutes of submaximal treadmill running to achieve a heart rate (HR) of 85% of predicted maximum for age. One such exercise test was preceded by "warm-up" and one was not. "Warm-up" consisted of three minutes of treadmill walking or jogging to attain 60% of predicted maximun HR for age. An identical incidence (77.8%) and severity (38.1% mean decrease in FEV1) of EIA was recorded after treadmill running whether preceded by "warm-up" or not. While this study does not support the concept that "warm-up" could reduce the likelihood of EIA, it is recommended that a longer, more intense "warm-up" involving interval exercise should be evaluated before rejecting the view that "warm-up" ameliorates EIA.
为了确定“热身”对运动诱发哮喘（EIA）的影响，18名受试者（平均年龄19.7岁）在跑步机上进行了5分钟的次最大强度跑步，以使心率达到年龄预测最大心率的85%。其中一次这样的运动测试之前进行了“热身”，另一次则没有。“热身”包括在跑步机上步行或慢跑3分钟，以使心率达到年龄预测最大心率的60%。无论是否在跑步机跑步前进行“热身”，运动诱发哮喘的发生率（77.8%）和严重程度（第一秒用力呼气量平均下降38.1%）均相同。虽然本研究不支持“热身”可降低运动诱发哮喘可能性的观点，但建议在否定“热身”可改善运动诱发哮喘这一观点之前，对涉及间歇运动的更长时间、更剧烈的“热身”进行评估。
