Sport-Specific Performance Metrics
Jump Count
Total vertical events per match — attacks, blocks, and serve-receive hops all logged
Jump Height
Peak vertical per jump — track block height improvement across a season
Impact Events
Spike contacts, diving digs, and floor impact events — cumulative load for liberos
Player Load
Set-by-set load breakdown — identify when attackers fade late in five-set matches
Effort / Work Rate
Intermittent effort pattern — high burst, quick recovery — quantify rest-to-work ratio
Direction Changes
Defensive shuffles, serve-receive positioning, and setting footwork — court IQ metric
Sprint Count
Transition sprints and emergency digs — court coverage speed by position
Rotation Speed
Arm-swing mechanics on attack swings — coaching tool for approach and contact
