Sport-Specific Performance Metrics
Rotation Speed
Trunk rotation velocity at impact — the single most important mechanical variable in golf
Player Load
Cumulative swing load — 18 holes × 75 swings = measurable fatigue accumulation
Effort / Work Rate
Low aerobic demand, high neuromuscular precision — baseline effort profile for coaches
Distance Covered
Full 18-hole walk — more than most athletes realize; hydration and fatigue monitoring
Impact Events
Club-ground and club-ball contact events — identify fat shots and thin contact patterns
Sprint Count
Cart path jogs and walking pace spikes — largely irrelevant, confirms true sport demand
Compass Heading
Shot direction orientation — combine with rotation data for shot-shape analysis

⚖ NFHS RULE STATUS
Golf is a practice-lane use case for HyperPulse. No NFHS competition rules govern wearable sensors in practice. USGA Rule 4.3 restricts devices during competition — HyperPulse is intended for training only.
