Sport-Specific Performance Metrics
Impact Events
Tackles, scrums, rucks, and mauls — the definitive contact-sport safety and toughness metric
Sprint Count
Breakaway sprints, support runs, and kick-chase bursts — backs vs. forwards profiling
Distance Covered
Full-match coverage — one of the highest-distance team sports behind soccer
Player Load
Cumulative load from contact, sprints, and scrums — manage forward pack workload
Rotation Speed
Offload pass mechanics, tackle technique, and scrum bind rotation — technical coaching data
Sprint Top Speed
Wing and fullback peak velocity — elite benchmark for backs is >21 mph
Direction Changes
Evasion moves, support-line angles, and defensive positioning — agility profile by position
Effort / Work Rate
Sustained output across 80 minutes — compare halves to identify late-game fading
