Error Correction Processing in Timing Lights

What is it about?

Timing lights are frequently employed to measure sprint performance of (team sport) athletes. As conventional single beam timing lights suffer from large measurement errors, systems employing error correction processing algorithms have been developed. But do these algorithms really work? In our study, we investigated if error correction processing is able to eliminate or to reduce measurement error on the basis of high-speed video analysis. We found that measurement errors were dramatically reduced compared to conventional single beam timing lights, indicating a good accuracy of measurement.

Why is it important?

An accurate measurement is the basis for sprint testing results to be used with confidence and to draw practical conclusions. Based on the high accuracy of timing lights employing error correction processing in this study, we recommend such systems for monitoring sprint performance to both scientists and practitioners.
