Q: My teenage son had a second spell of bad breathing during a school basketball game. Even when he stopped playing, it felt like somebody was sitting on his chest. Could this be due to asthma?
Dr. Bassett: Your suspicions might be warranted, particularly if your son has a history of allergies and asthma. Exercise-induced bronchoconstriction or EIB (also called exercise-induced asthma), can be present in more than one-third of those with seasonal allergies and in up to 90 percent of those with chronic asthma.
With EIB, coughing, chest tightness, shortness of breath and/or wheezing generally occur within 3 to 8 minutes of strenuous exercise.
Low-stress exercise, such as walking, jogging and golf, or fitness involving short bursts, such as biking, baseball, football, volleyball and weight training, tend to be better tolerated by those who have EIB. Swimming is also a good option because of the humid, warm conditions.
Less optimal choices include: soccer, long-distance running and basketball, due to their prolonged and intense activity level.
Some of the key elements for successful exercising with asthma are:
‚Ä¢ an adequate warm-up and cool down;
‚Ä¢ avoiding strenuous outdoor fitness at high risk times, including days with an ozone alert, high pollen count or cold, dry weather conditions;
‚Ä¢ and pre-treatment prior to exercise with a prescription “rescue” inhaler.
A peak flow measurement taken before and after exercise and lung function tests performed by an allergist can help to confirm an EIB diagnosis and the proper treatment.
