Running produces a greater amount of post-exercise bronchoconstriction than other forms of exercise carried out a similar metabolic rates. The treadmill can be used to provide a standardized form of exercise when studying the asthmatic child. The severity of post-exercise bronchoconstriction depends upon the rate of working on the treadmill and the duration of exercise. A maximum response is obtained by six minutes of running at an uphill slope of 10% at a speed of 5 kmph (3 mph). Even with this type of test, there is still considerable variation in the response from time to time and greatest reporducibility is obtained by repeating the test within one week. Treadmill exercise tests may be used in the diagnosis of asthma and in the assessment of its likely severity.
与在相似代谢率下进行的其他形式运动相比，跑步产生的运动后支气管收缩程度更大。在研究哮喘儿童时，跑步机可用于提供标准化的运动形式。运动后支气管收缩的严重程度取决于在跑步机上的运动速率和运动持续时间。以每小时5公里（3英里）的速度在10%的上坡坡度上跑步6分钟可获得最大反应。即使是这种类型的测试，每次的反应仍存在相当大的差异，并且通过在一周内重复测试可获得最大的可重复性。跑步机运动测试可用于哮喘的诊断及其可能严重程度的评估。
