Caffeine Helps Exercise-induced Asthma

An Indiana University study found that the ingestion of caffeine within an hour of exercise can reduce the symptoms of exercise induced asthma.

A large dose of 9 milligrams of caffeine per kilogram of body weight was as effective as the use of a salbutamol inhaler, which is commonly used to treat or prevent exercise-induced asthma. Smaller amounts of caffeine, for example, 3 and 6 milligrams of caffeine per kilogram of body weight,also reduced the wheezing, coughing and other symptoms.

Reference: "Comparative and Synergistic Effects of Caffeine and Albuterol on The Severity of Exercise-Induced Bronchoconstriction," was presented at the American College of Sports Medicine conference during the Respiratory Session on May 29. Co-authors include lead author Timothy A. VanHaitsma, now at the University of Utah; Martin R. Lindley, Loughborough University, United Kingdom; and David Koceja and Joel Stager, IU's Department of Kinesiology.
