| Abstract: | Purpose] Cigarette smoking increases oxidative stress, which is a risk factor for
several diseases. Moreover, strenuous exercise has been shown to induce plasma and
pulmonary oxidative stress in young cigarette smokers. However, no previous reports have
demonstrated whether plasma and pulmonary oxidative stress occur after moderate-intensity
exercise. Therefore, the aim of this study was to clarify whether moderate-intensity
exercise induces pulmonary and plasma oxidative stress in smokers. Subjects] Ten young
male smokers and 10 young male nonsmokers participated in this study. Methods] Plasma
hydroperoxide concentrations were measured at baseline and then immediately and 15 min
after moderate-intensity exercise. Hydrogen peroxide concentrations in exhaled breath
condensate were measured at baseline and after exercise. Results] No significant
interactions were found between smokers and nonsmokers in terms of hydroperoxide or
hydrogen peroxide concentrations following moderate-intensity exercise at any time point.
Conclusion] These findings suggested that moderate-intensity exercise did not induce
plasma or pulmonary oxidative stress in young cigarette smokers.Key words: Oxidative stress, Cigarette smoker, Moderate-intensity exercise |
