Sport-Specific Performance Metrics
Rotation Speed
Peak trunk/limb rotation velocity — the #1 metric for pitchers, hitters, and fielders
Sprint Top Speed
Home-to-first burst speed — elite threshold is sub-4.3 seconds
Sprint Count
Max-effort sprint events: steal attempts, gap-run reads, hustle plays
Player Load
Cumulative biomechanical load — essential for pitch-count management and arm health
Impact Events
Contact events: pitch impacts, fielding shocks, diving plays — longitudinal arm care data
Distance Covered
Total field coverage — tracks outfield range and infield positioning patterns
Effort / Work Rate
Intensity bursts vs. recovery — intermittent sport load profiling for pitchers
Jump Count
Leaps, dives, and jump-throw events — outfield wall play and catcher blocks
