[Methods of detection of exercise-induced asthma]

Different forms of physical exertion induce different degrees of severity of exercise induced asthma. Standardized methods are needed to quantify this phenomenon. These methods should include the possibility to examine lung function more differentially, especially to modify the conditions of inhaling air. Free running is difficult to standardize as an exercise. Bicycle-ergometers provide the most reliable results, allowing for triangular or rectangular exercise. Results should be related to fat-free body weight.
