Abstract

The purpose of this study was to gain insight into the physiological principles driving blood flow and fatigue both during and following different levels of intermittent exertion. Utilizing diffuse correlation spectroscopy (DCS) allowed microvascular blood flow (BF) to be observed continuously, providing new insight into the behaviors of BF within the exerting muscle. This experiment was conducted with 11 healthy, adult participants, (5 male, 6 female), fatiguing the First Dorsal Interosseous (FDI) muscle through the abduction of the index finger. The study monitored BF and fatigue in response to 3 levels of intermittent exertion (20%, 30%, and 40% MVC) under constant duty cycle (DC=50%) and cycle time (CT=90s). MANOVA on BF and MVC showed that time, exertion level (EL), and their interaction were significant during both exertion and rest (p
