A top athlete who is exhausted and underperforming but experiencing no other symptoms will nonetheless be tested for allergies or exercise-induced asthma and offered treatment. As is the case with many advances in sports performance medicine, however, knowledge about these breathing problems and how to treat them rarely make it to everyday athletes — people who possibly could benefit the most from it.
You might think that you would have been diagnosed by now if you had allergies or exercise-induced asthma. But you can suffer from these illnesses for years with no obvious symptoms. A person with seasonal allergies may appear fine at his annual physical in November; another may breathe normally during a visit with her doctor any time of the year but become asthmatic when she starts exercising and demands more of her body.
If you experience unusual exhaustion, fatigue and underperformance, allergies should be your first suspect. The only obvious symptom may be that you don't perform well during certain times of the year. Exercise performance physician Massimo Testa discovered this during his work with cyclists. Michele Bartoli, for example, became a strong one-day racer and two-time World Cup winner after he was diagnosed with seasonal allergies.
Bartoli managed his allergies by avoiding races during May and June, when his allergies were at their worst.
If you experience months or seasons when your body mysteriously underperforms, you may have seasonal allergies. See a doctor for a diagnosis and for help managing your symptoms. Like Bartoli, you may have to identify times of the year when you can push yourself extra hard and expect optimal performance, and other times when you need to back off.
The symptoms of exercise-induced asthma are equally subtle. Exercise-induced asthma consists of mild bronchial spasms (or asthma) triggered by exercise. Many sufferers aren't even aware that they have it. Symptoms include coughing during warmup or cool-down periods, the sensation of shortness of breath when you are breathing cold or polluted air, and breathing that is cut short. If breathing problems force you to quit workouts or leave you lagging behind your workout partners, it's worth talking to your doctor.
Meanwhile, avoid starting workouts too quickly in dry, cold or polluted air, particularly when you are dehydrated. (Dehydration is a key trigger of exercise-induced asthma. That extra air you breathe dries out your airways, making their receptors hypersensitive, which causes coughing.)
You may also need longer warmups so that your muscles, heart and lungs are prepared when you begin your workout, alleviating the need to breathe as deeply or as often. If you start slowly enough, you may be able to exercise through asthma.
At present there is no cure for asthma, but you can increase your threshold. Rarely do people with mild asthma require inhalers; their lung function in resting condition is normal. Simple medication, modified warmup methods and breathing exercises that strengthen your respiratory muscles may be all you need for mild asthma.
