The study aimed to determine whether collision loads derived from microtechnology can distinguish between collision performance outcomes and to compare the physical and analytical aspects of collision performance across positional groups.


Thirty-seven professional male rugby union players were involved in the study.
Collision events from 11 competitive matches were coded based on specific tackle and carry classifications.
Microtechnology units operating at 10Hz were used to automatically detect collision events.
Collision events were identified, coded (as tackle or carry), and timestamped at the collision contact point using game analysis software.
Attacking and defensive performances of 1609 collision events were analyzed.

Collision loads were significantly higher during dominant collisions compared to neutral and passive collisions, as well as during tackles and carries.
Forwards generally reported a greater number and frequency of collisions but lower loads per collision and velocities at the collision point compared to backs.
Microtechnology devices accurately, sensitively, and specifically identified collision events with high percentages of accuracy.

Microtechnology is validated as a reliable means of distinguishing between tackle and carry performance.
The data derived from microtechnology regarding collision loads can effectively track and monitor collision events in both training and game scenarios.
