Pulmonary Oxidative Stress is not Increased by Short-period High Intensity Exercise in Healthy Young Subjects

Abstract

[Purpose] This study investigated whether a short-period high intensity exercise induced oxidative stress in lungs. [Subjects] Subjects were 11 healthy young males. [Methods] Before and after the short-period high intensity exercise Wingate test performed on a cycle ergometer, exhaled breath condensate (EBC) was collected for 15 minutes. We measured hydrogen peroxide (H₂O₂) concentration and biological antioxidant potential (BAP) in EBC before and after the exercise. [Result] The H₂O₂ concentration and BAP in EBC did not show any significant changes after the exercise. [Conclusion] The short-period high intensity exercise has little impact on the H₂O₂ content in EBC of healthy young subjects.
