| Popis: | Introduction Fitness testing forms an important role in evaluating an individual’s athletic performance and potential. Its assessment is a complex, multifaceted process comprising of cardiovascular endurance, strength, and flexibility testing as well as body composition evaluation. The respiratory element of this is commonly overlooked and undervalued despite dyspnoea, upper airway distress, recurrent infections and coryzal symptoms being a notable cause of underperformance in athletes. Previous studies have postulated that airway hyperresponsiveness or repeated injury and repair process of the respiratory epithelium, can lead to structural and functional changes, and are then responsible for the underlying airway dysfunction in athletes. It therefore seems feasible that understanding this could allow management and subsequent improved athletic performance. Objectives To examine the prevalence of airways disease in athletes attending a dedicated sports cardiology service To evaluate the correlation between respiratory physiology and exercise performance. Method Over 12 months the data of 82 athletes, comprising of team sports and individual endurance athletes, attending a dedicated sports cardiology service were retrospectively evaluated including clinical history, baseline spirometry and cardiopulmonary exercise test (CPET). FeNO and spirometry with reversibility were performed in individuals with respiratory symptoms or abnormal baseline spirometry. Results 14/82 (17%) had abnormal baseline spirometry defined by lower limit of normal, of which 6/14 had significant reversibility and 4/14 had FeNO >40ppb. A further 6/82 (7.3%) had FeNO >40ppb with normal baseline spirometry. 24.3% of the athletes had pulmonary function testing highly suggestive or diagnostic of airways dysfunction. 13/82 (15.9%) were commenced on inhaled therapy based on the results of these investigations. Using a Welch’s t-test to analyse the data there was a statistically significant difference between FEV1, FEV1/FVC ratio and breathing reserve for those with normal versus abnormal investigations. Conclusion These results demonstrate airway disease is highly prevalent in an athletic population. Results suggest that premature encroachment on ventilatory reserves may negatively affect performance in high achieving athletes. Addressing this could potentially have a positive influence on performance. A prospective study to further evaluate the prevalence of airways disease and impact on performance is underway. |
