    ABSTRACT

    Estimating the calories burned during exercise is important for understanding physical activity and managing weight. Wearable tools for counting calories, such as smartwatches, provide the opportunity to make these measurements outside of a laboratory environment but have errors of 40-80%, making them ineffective. Dr. Slade and colleagues developed a new approach to estimate calories burned by using two inertial measurement units placed on the shank and thigh of one leg. Using machine learning, they are able to estimate calories once per step to rapidly capture changes in energy expenditure without physiological signal delays, as is common when making these measurements based on heart rate and respirometry. Their data-driven approach has approximately 13% error when tested with a physiologically diverse adult population during walking, running, stair climbing, and biking.

    In the first half of the webinar, Dr. Slade will discuss the background and experimental work used to design and validate the Wearable System. In the tutorial during the second half of the webinar, Dr. Slade will share tips and guide you through the code so you can utilize this approach to estimate calories burned from wearable sensors in your own studies.
