A high-speed digital video camera can be used to obtain highly reliable short-sprint split times. Split time data can be used to estimate instantaneous position, velocity, and acceleration by fitting an exponential function to the known positional data yielding force-velocity (F-V) profiles that may provide more information than just sprint times alone. The purpose of this study was to evaluate the between-rater reliability of different exponential functions used to estimate instantaneous data. A high-speed digital video camera was used to obtain split times from eleven male high-school ice hockey players performing a 6.10 m sprint and a separate top speed test. Including an optimization parameter and using a player’s measured maximal horizontal velocity instead of estimating it tended to produce better between-rater reliability.
