| مستخلص: | Exercise puts a stress on the body and results in multiple physiological changes despite the homeostatic mechanisms in place that try to maintain normalized conditions in the body. One of the factors that are transiently elevated with exercise of sufficient intensity and duration is the production of reactive oxygen/nitrogen species (RONS) which act as signal molecules that can influence adaptation. If these RONS accumulate beyond the normal level this is known as oxidative stress (OS). If OS is maintained over time, then homeostasis may be disrupted and adverse responses may occur, leading to dysfunction or disease. Previous studies have reported that most types of exercise (resistance, aerobic, and/or high intensity interval trainings) can induce an acute OS. The literature suggests that sufficient intensity and duration of exercise are needed to increase OS during exercise and is often noted with sample taken immediately after the exercise. Aerobic activities of at least 65-70%VO2max for at least 10 minutes have reported increased OS based on blood and/or muscle markers. Unfortunately, most studies only determined immediate post exercise responses. Only one study has reported a time-course of OS immediately after exercise and the sample period ended 30 minutes after exercise. However, no study has examined the timeline of OS biomarkers during and after an exercise. Additionally, there is limited information dealing with evening exercise. In this study, two OS markers were determined: lipid oxidation marker (oxidized low-density lipoprotein, LDLox) and the antioxidant glutathione and its status (glutathione status; the ratio of oxidized glutathione (GSSG), to total glutathione, TGSH [GSSG/TGSH]. The purposes of this study were 1) to determine the time course accumulation in the blood markers over the 1-hour exercise and 2) to determine the time course of the removal of OS blood markers in the 1 hour after exercise. To accomplish these objectives, 10 subjects parti |
