Preliminary work on the determination of mechanical power during running based on kinetic data

Abstract

Mechanical power output can be used to quantify performance in order to plan and execute appropriate training programs. To measure mechanical power output during running, the dependent ground reaction forces, among others, should be recorded. Existing wearable devices for determining mechanical power during running do not measure these forces. Instead, they estimate them, for example, based on information from the GPS, inertial sensors, or other kinematic data (Cerezuela-Espejo et al., 2020). With the overall goal of determining mechanical power during running based on kinetic data, we performed long-duration measurements as a first step (Krumm, Koska, Wakode, Odenwald, & Maiwald, 2022). These measurements allow us to estimate vertical ground reaction forces based on plantar pressure. In this paper, we present the regression model developed for this purpose.
