According to a new study at Ohio State University, college athletes may face a higher risk of exercise-induced asthma, though it often goes undiagnosed.

Exercise-induced asthma, known as EIA for short, causes the airways to narrow during and after exercise. It's common in people who already have asthma (80 to 90% have it), but it also occurs in about 10% of people who have never been diagnosed with asthma before.

However, the research published in the journal Medicine and Science in Sports and Exercise showed that elite college athletes had a higher risk of having EIA than the general public. In fact, 39% of the athletes studied had EIA; 89% of them had never been diagnosed with asthma before that. The study in question was a small one, though. Only 107 athletes were examined, and few studies have been done in the past of EIA in college athletes. So more research is needed to confirm these findings.
