Abstract

A significant share of rowers does not have access to professional supervision by coaches. However, proper technique is a key component for both success in competitions and to prevent injuries or long-term induced postural deformity. In cooperation with national rowing coaches we developed a sensor system to continuously monitor the rower's seat position. It allows offline data analysis and complements existing state-of-the art methods to analyze rowing technique based on video footage. Both quantitative analyses for coaches as well as qualitative and visual feedback for athletes are provided. We tested our system on the water and present exemplary data and analyses.
