Design of a real-time performance feedback system for sprinter starts

摘要

In this paper, we report on the design of a portable set of starting blocks for personal training to provide immediate feedback on the quality of sprinters' starting performance. The prototype set features two portable starting blocks with embedded sensors and a microcontroller for data collection and analysis. Testing was conducted with sprinters to validate and gauge the overall functionality of the prototype. Our preliminary results show that the force-time data produced using the prototype system do correlate with qualitative coaches' scores of sprinter's performance, and that the prototype system does show considerable promise for performance feedback.
