On-body sensor systems for sport are challenging since the sensors must be lightweight and small to
avoid discomfort, and yet robust and highly accurate to withstand and capture the fast movements associated
with sport. In this work, we detail our experience of building such an on-body system for track athletes.
The paper describes the design, implementation and deployment of an on-body sensor system for
sprint training sessions. We autonomously profile sprints to derive quantitative metrics to improve training
sessions. Inexpensive Force Sensitive Resistors (FSRs) are used to capture foot events that are subsequently
analysed and presented back to the coach. We show how to identify periods of sprinting from the
FSR data and how to compute metrics such as ground contact time. We evaluate our system using force
plates and show that millisecond-level accuracy is achievable when estimating contact times.© 2011 Elsevier B.V. All rights reserved.
