Physical activity is often continuously monitored using at-home fitness trackers or activity monitors which only provide global measures of physical activity and not information on muscle health or performance. The goal of this research project is to determine the feasibility of using wireless wearable near-infrared spectroscopy (NIRS) sensors to enhance the understanding of varying levels of physical activity on vascular muscle health. The findings of this research may increase the knowledge of varying levels of physical activity on vascular muscle health.
