Abstract

OBJECTIVES: Redox homeostasis and redox-sensitive protein signaling play a role in exercise-induced adaptation. The effects of sprint-interval exercise (SIE), high-intensity interval exercise (HIIE) and continuous moderate-intensity exercise (CMIE), on post-exercise plasma redox status are unclear. Furthermore, whether post-exercise plasma redox status reflects skeletal muscle redox-sensitive protein signaling is unknown. DESIGN: In a randomized crossover design, eight healthy adults performed a cycling session of HIIE (5×4min at 75% Wmax), SIE (4×30s Wingate's), and CMIE work-matched to HIIE (30min at 50% of Wmax). METHODS: Plasma hydrogen peroxide (H2O2), thiobarbituric acid reactive subst..
