“…This is on the high end of the range (10 -31%) recorded in past studies, including self-reports on prevalence of EIB in athlete populations. 11,12,15,16 In addition, 47% of the athletes in this study perceived symptoms of EIB. These data raise concern that some athletes may not be appropriately screened and may potentially be experiencing silent episodes of EIB, resulting in possible long-term respiratory health complications and a potential fatal event.…”

BACKGROUND: Exercise-induced bronchoconstriction (EIB) can lead to long-term respiratory illness and even death. EIB prevalence rates are both high and variable in college athletes. Also, prevalence rates may be underestimated due to ineffective screening. The purpose of this study is to investigate the prevalence of EIB and the perceived impact of EIB in college athletes via a self-report questionnaire. METHODS: A self-report EIB questionnaire was administered to college athletes on 8 different sports teams. Information collected was used to identify athletes who selfreported: (1) a history of EIB and/or asthma, (2) respiratory symptoms during exercise, (3) medication use, and (4) concern about EIB. RESULTS: Results showed that 56 of 196 athletes (28.6%) self-reported a history of EIB or asthma. Over half (52%) reported a history of EIB/asthma or current EIB symptoms. Forty-six of the 140 athletes (32.9%) who did not report a history of EIB or asthma indicated symptoms of EIB during sports, training, or exercise. Fourteen of 56 athletes (25%) self-reporting a history of EIB or asthma did not report the use of a respiratory medication. Nineteen of 196 athletes (9.7%) reported being concerned that EIB was adversely affecting their sports performance. CONCLUSIONS: College athletes self-report a high prevalence of EIB or asthma. Although college athletes may not report a history of EIB or asthma, they indicate symptoms of EIB. A majority of athletes reported a history or current symptoms related to EIB or asthma. Many athletes with a history of EIB or asthma are not taking any asthma medication. Last, athletes report concern about EIB adversely affecting their sports performance. More work is needed using a combination of a screening questionnaire and standardized EIB testing to develop a validated tool for accurately screening and diagnosing EIB in college athletes.

“…Injury to the airway epithelium would expose sensory nerve endings to noxious agents (such as air pollutants and allergens) and may trigger a neurogenic inflammation (28). In swimmers (7), runners (29), and ice-arena athletes (32)—all of whom are frequently exposed to noxious airborne agents (e.g., chlorine derivatives and exhaust gas from cars or from fossil-fueled ice-resurfacing machines)—high prevalence of respiratory symptoms and pulmonary dysfunction has consistently been reported. That hyperpnea of dry air may stimulate cough and mucus hypersecretion independently of a change in airway caliber may explain why wheeze, which is more directly linked to airflow limitation (34), differentiated better EVH-positive athletes from EVH-negative athletes in Part 1 of this study.…”

“…Athletes frequently report respiratory symptoms on exertion, with almost a third of recreational roadrunners (29) and more than 70% of elite athletes—whether summer athletes (17), swimmers (35), or winter athletes (7)—reporting cough, wheeze, breathlessness, chest tightness, and/or mucus hypersecretion during or shortly after exercise. In a significant number of athletes, respiratory symptoms may arise from local release of inflammatory mediators (such as prostaglandins or leukotrienes) after dehydration of the airway surface lining in response to exercise hyperpnea and from ensuing narrowing of the airways (3).…”

PurposeA change in the perception of respiratory symptoms after treatment with inhaled beta2 agonists is often used to aid diagnosis of exercise-induced bronchoconstriction (EIB). Our aim was to test the association between subjective ratings of respiratory symptoms and changes in airway caliber after induced and inhibited bronchoconstriction in athletes with EIB.MethodsEighty-five athletes with diagnosed or suspected EIB performed a eucapnic voluntary hyperpnea (EVH) challenge with dry air. Of the 45 athletes with hyperpnea-induced bronchoconstriction [i.e., post-EVH fall in forced expiratory volume in 1 s (FEV1) ≥10%, EVH−], 36 were randomized in a double-blind, placebo-controlled, crossover study. Terbutaline (0.5 mg) or placebo was administered by inhalation 15 min before EVH. Spirometry (for FEV1) was performed before and after EVH, and respiratory symptoms were recorded 15 min after EVH on visual analog scales.ResultsTerbutaline inhibited bronchoconstriction (i.e., maximal fall in FEV1 <10% after EVH) in 83% of the EVH-positive athletes, with an average degree of bronchoprotection of 53% (95% confidence interval [CI], 45% to 62%). Terbutaline reduced group mean symptom scores (P < 0.01), but the degree of bronchoprotection did not correlate with individual differences in symptom scores between terbutaline and placebo. Of the 29 athletes who had less than 10% FEV1 fall after EVH in the terbutaline condition, almost half (48%) rated at least one respiratory symptom higher under terbutaline, and more than one quarter (28%) had a higher total symptom score under terbutaline.ConclusionSelf-reports of respiratory symptoms in conditions of induced and inhibited bronchoconstriction do not correlate with changes in airway caliber in athletes with EIB. Therefore, subjective ratings of respiratory symptoms after treatment with inhaled beta2 agonists should not be used as the sole diagnostic tool for EIB in athletes.

“…EIB can occur in children and adults of various fitness levels, ranging from recreational to elite competitors, 15 16 with a reported prevalence of 10-50% or greater in high level athletes, depending on sport and surveillance or diagnostic methodology. 17 18 Individuals who are exposed to high concentrations of airborne particulate matter during high ventilation exercise have an increased incidence of EIB (see box 1).…”
