Exercise is one of the crucial factors responsible for asthma development and exacerbation. The purpose of the present study was to assess the risk of bronchial asthma in female athletes. Spirometric evaluations and physical exercise test were performed and exhaled nitric oxide (eNO) levels were measured in 12 female elite cross-country skiers. Serum concentrations of interleukin 1 beta (IL-1ß), tumor necrosis factor-alpha (TNF-a), and interleukin 6(IL-6) were measured in all subjects before exercise, immediately after it, and after 15 min of recovery. Peak eNO values were 18.7?±?4.8 (ppb) and did not confirm the risk of early bronchial asthma symptoms. A graded exercise test caused significant increases in TNF-a and IL-1ß concentration (p?
