“…4,5,13,14 However, another study showed a low prevalence rate among college athletes when using the eucapnic voluntary hyperventilation testing method. 15 Regardless of the variability seen with the prevalence of EIB in athletic populations, a previous workgroup reported a substantial EIB prevalence (30 -70%) in athletic populations using a variety of diagnostic methods.…”

“…Our results are also consistent with previous studies reporting a lack of association between college athletes who were EIB-positive by objective testing with a previous history of EIB or asthma. 4,5 Parsons et al 5 showed that only 14% of college athletes who were EIB-positive had a previous history of EIB or asthma. Dickinson et al 4 showed that only 27% of EIB-positive elite athletes reported a history of EIB or asthma.…”

“…2,3 Moreover, previous studies reported that EIB was 3-5 times more prevalent in athletes when compared with the general population. [4][5][6] Morbidity associated with EIB is speculated to originate from reoccurring episodes of inflammation during repeated bouts of exercise, leading to airway remodeling and chronic irreversible airway obstruction. 7,8 More importantly, the potential for a severe episode of EIB leading to mortality has been noted in athletes.…”

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. Prevalence rates may be underestimated due to ineffective testing and screening. The purpose of this study was to investigate the prevalence of EIB in college athletes by a standardized EIB test that can be used on many college campuses. In addition, we assessed the usefulness of self-reporting EIB/asthma (1) history, (2) symptoms, and (3) respiratory medication obtained from a simple screening questionnaire for predicting an EIB-positive athlete. METHODS: A standardized EIB test and self-report questionnaire were administered to college athletes on 10 different sports teams. Information collected included pulmonary function (spirometry), expired gas analysis (maximal oxygen uptake), CO 2 production, minute ventilation, EIB/asthma history, current symptoms, and medication use. RESULTS: Results showed that 34 of 80 athletes (42.5%) were EIB-positive by standardized exercise testing. The majority (76.5 and 58.8%) of the 34 athletes who tested positive self-reported a negative history or no symptoms, respectively. Also, 79.4% of the athletes who tested positive for EIB reported not using a respiratory medication. There were no significant differences in a positive EIB test when assessing interactions for history (P ‫؍‬ .93), current symptoms (P ‫؍‬ .12), or respiratory medication use (P ‫؍‬ .66). CONCLUSIONS: A high proportion of college athletes tested positive for EIB when using a standardized test. Positive history, current symptoms of EIB/asthma, and respiratory medication use were not predictive of a positive test. Many EIB-positive athletes are not using a respiratory medication. More work is needed to develop an effective screening tool and improve education for EIB in college athletes.

Breathing concerns in athletes are common and can be due to a wide variety of pathology. The most common etiologies are exercise-induced bronchoconstriction (EIB) and paradoxic vocal fold movement disorder (PVFMD). Although some patients may have both, PVFMD is often misdiagnosed as EIB, which can lead to unnecessary treatment. The history and physical exam are important to rule out life threatening pulmonary and cardiac causes as well as common conditions such as gastroesophageal reflux disease, sinusitis, and allergic etiologies. The history and physical exam have been shown to be not as vital in diagnosing EIB and PVFMD. Improvement in diagnostic testing with office base spirometry, bronchoprovocation testing, eucapnic voluntary hyperpnea (EVH) and video laryngoscopy are essential in properly diagnosing these conditions. Accurate diagnosis leads to proper management, which is essential to avoid unnecessary testing and save healthcare costs. Also important to the physician treating dyspnea in athletes is knowing regulations on medications, drug testing, and proper documentation needed for certain organizations. The differential diagnosis of dyspnea is broad and is not limited to EIB and PVFMD. Ruling out life threatening cardiac and pulmonary causes with a proper history, physical, and appropriate testing is essential. The purpose of this review is to highlight recent literature on the diagnosis and management of EIB and PVFMD as well as discuss other potential causes for dyspnea in the athlete.

In contrast, there is limited evidence to suggest inhaled doses of β 2 -agonist have signiicant ergogenic efects according to a study by Pluim et al he current List of banned substances and methods allows athletes to inhale up to 1600 μg salbutamol without the requirement of a TUE [3].…”

John et al., J Sports Med Doping Stud 2015, 5:S2 http://dx.doi.org/10.4172/2161 Research Article Open Access AbstractObjectives: Investigate the ergogenic effect of inhaling up to 1600 µg of salbutamol on intermittent running performance in pre-fatigued soccer players. Methods:In a single blind randomised repeated measures design seven male and six female soccer players volunteered to participant. All participants were regularly playing competitive soccer and had no history of asthma. Following familiarisation sessions participants visited the exercise physiology laboratory on three occasions to complete an intermittent running protocol followed by twelve 17.5 m sprints. Prior to each trial participants inhaled either: placebo, 800 µg inhaled salbutamol (SAL800) or 1600 µg inhaled salbutamol (SAL1600). Following completion of the sprints a sample from the irst urine passed was analysed for salbutamol concentration. A repeated measures ANOVA was used to compare the mean sprint time, maximal sprint power, peak blood lactate post sprints and post sprint salbutamol urine concentration between conditions.Results: Mean sprint time, maximum power, maximum velocity, peak HR and peak blood lactate during the 17.5 m sprints were not signiicantly different between treatments in soccer players. There was no signiicant difference between male and female players in urine drug concentration following SAL800 (mean + SD; 201.47 + 294.47 ng.ml -1 vs. 180.2 + 102.15 ng.ml -1 ) or SAL1600 (739.24 + 549.21 ng.ml -1 vs. 879.58 + 633.14 ng.ml -1 ). Three players urine drug concentrations were above the WADA decision limit set at 1200 ng.ml -1 . Conclusions:Inhaling up to 1600 µg inhaled salbutamol did not signiicantly improve repeated sprint performance. However, inhalation of 1600 µg may result in a urine concentration above the current WADA upper limit and decision limit leading to a positive test. Athletes should ensure they use inhaled salbutamol at therapeutic doses to avoid the risk of breaching the WADA decision limit.
