(a) Predicted FEV1% in marathoners and half-marathoners at baseline, peak and recovery compared to sedentary controls. Predicted FEV1% significantly decreased after participating in a M while remaining stable in HM. There were no differences detectable between M, HM and sedentary controls. M, marathon; HM, half-marathon; baseline, 1–2 days before the run; peak, immediately after the run in the finishing area; recovery, after 2–7 days of recovery; FEV1, forced expiratory volume after one second. *p < 0.05. (b) Predicted FVC % in marathoners and half-marathoners at baseline, peak and recovery compared to sedentary controls. Predicted FVC % significantly decreased after participating in a M and remained stable in HM. There were no differences detectable between M and HM runners and sedentary controls. M, marathon; HM, half-marathon; baseline, 1–2 days before the run; peak, immediately after the run in the finishing area; recovery, after 2–7 days of recovery; FVC, forced vital capacity. **p < 0.01. (c) FEV1/FVC ratio in marathoners and half-marathoners at baseline, peak and recovery compared to sedentary controls. FEV1/FVC ratio remained stable in M and HM runners. There were no differences detectable between M and HM runners and sedentary controls. M, marathon; HM, half-marathon; baseline, 1–2 days before the run; peak, immediately after the run in the finishing area; recovery, after 2–7 days of recovery; FVC, Forced vital capacity. **p < 0.01.
