Visually identified breakpoints in muscle oxygen saturation are not equivalent to ventilatory thresholds in national-level triathletes

Abstract Purpose Portable near-infrared spectroscopy (NIRS) enables cost-effective monitoring of muscle oxygen saturation (SmO 2 ) during exercise, presenting a promising alternative for delineating exercise intensity domains. This study investigated whether SmO 2 breakpoints (BP...
