Can You Predict Ground Reaction Force from a Hip-Borne Accelerometer during Load Carriage?

Research Paper Title Predicting Ground Reaction Force from a Hip-Borne Accelerometer during Load Carriage. Background Ground reaction forces (GRF) during load carriage differ from unloaded walking. Methods to quantify peak vertical GRF (pGRFvert) of Soldiers walking with loads outside of a laboratory are needed to study GRF during operationally relevant tasks. Therefore, the purpose of… Read More

Physical Activity: Linking Emotion & Metabolic Heart Rate

Research Paper Title Improving Real-Life Estimates of Emotion Based on Heart Rate: A Perspective on Taking Metabolic Heart Rate Into Account. Background Extracting information about emotion from heart rate in real life is challenged by the concurrent effect of physical activity on heart rate caused by metabolic need. “Non-metabolic heart rate,” which refers to the… Read More

Average Steps per Day & Levels of Obesity: Any Connection?
