Abstract

Timing light systems are commonly used to measure sprint times of athletes. In this study, the reliability and effect of timing light height on sprint times was investigated. Two sets of timing lights set at hip and shoulder height, simultaneously timed subjects over 10 and 20 meters. The within-trial variation of both timing light heights were equally consistent; all coefficients of variation (CV) less than 1.2% with less variability associated with the longer (20 m) distances (CV < 0.85%). The typical error between the two timing light heights for both distances was small (
