Chronic inflammatory disease of the lower respiratory tract characterized by acute or subacute episodes of dyspnea, cough and rarely catarrh is defined as asthma. Numerous studies show that an aerobic training program increases lung capacity and functionality and improves the condition of the cardiovascular system, which helps reduce the severity and frequency of asthma symptoms by increasing overall endurance during physical activity. This case study seeks to find out whether monitoring the results of Spirometry, FeNO test and AQLQ(S) questionnaire can quantify and explain in more detail the impact of an aerobic training program on asthma symptoms, i.e. To quantify the direct or indirect (adaptation to an aerobic training program) impact on asthma symptoms. It also serves to familiarize with the prerequisites for creating a database which would be used on asthmatics for specifying the activity that suits them best. The case study involved a former female gymnast (26 years old, 63kg, 172cm) diagnosed with allergic asthma. The Spirometry test, FeNO test and AQLQ (S) were measured at four points through the initial state, two transitive states and the final state. Factor analysis of the AQLQ (S) results resulted in three factors that were compared with the results of the Spirometry and FeNO test. A correlation of MEF 75 (0.907), FEV 1 (0.901), IVC (0.856), PEF (0.849), FVC (0.784) with the first factor (SA), FeNO (0.947) with the second factor (IOZ) and FEV 1/IVC (0.989), MEF 25 – 75 (0.870), MEF 25 (0.864) and MEF 50 (0.791) with the third factor (G) were found. For easier interpretation of the results, the correlation between individual factors, the results of the Spirometry and FeNO test in relation to the measurement were shown graphically. The results suggest the possibility of quantifying the impact of an aerobic training program on asthma symptoms and potentially creating a database which would be used on asthmatics for specifying the activity that suits them best when larger study would be organized.
