Tackle and impact detection in elite Australian football using wearable microsensor technology.

The effectiveness of a wearable microsensor device (MinimaxX(TM) S4, Catapult Innovations, Melbourne, VIC, Australia) to automatically detect tackles and impact events in elite Australian football (AF) was assessed during four matches. Video observation was used as the criterion measure. A total of 352 tackles were observed, with 78% correctly detected as tackles by the manufacturer's software.

Quantification of tackling demands in professional Australian football using integrated wearable athlete tracking technology.

Objectives: To describe and quantify the frequency, velocity and acceleration at impact during tackling in Australian football using a combination of video and athlete tracking technology.

Design: Quasi-experimental.

Methods: Data was collected from twenty professional Australian Football League players during four in-season matches.
