Satellite tracking units that measure how far and fast athletes move.
GPS in sport refers to wearable satellite-tracking devices, usually worn between the shoulder blades in a vest, that log an athlete's movement during training and matches. They generate external-load metrics such as total distance covered, high-speed running distance, sprint counts, and acceleration/deceleration efforts.
For clinicians, GPS data provides an objective external-load picture that can be cross-referenced with internal-load markers (RPE, heart rate, wellness scores) and injury or return-to-play timelines. It supports conversations with coaching staff about whether a spike in high-speed running or acceleration load may be linked to a player's soreness, fatigue, or re-injury risk, and helps inform graded return-to-play progressions after injury.
Units are worn during every training session and match, and the data is downloaded and processed by sport scientists into standard metrics like total distance, distance per minute, high-speed running distance, sprint distance, and acceleration/deceleration counts. Clinicians typically review this data alongside physios and performance staff, often looking at rolling averages or acute:chronic workload ratios rather than single-session numbers when discussing an individual's loading pattern.
Accuracy depends on sampling rate (typically 10Hz or higher for adequate resolution) and satellite signal quality, so short, sharp movements like accelerations, decelerations, and change of direction are measured less reliably than steady-state running. GPS also only captures external load, not the internal physiological or biomechanical strain an individual experiences, so it should never be interpreted in isolation to make return-to-play or load-management decisions.
