Technical Details

  • Variable Type: Discrete Metric
  • Data Type: Float
  • Units: N/A (ratio)
  • Column Name: reactive_strength_index_modified
  • Measurement: Jump height divided by appropriate time or drop metric (definition may vary by jump type)

Description

Reactive Strength Index Modified is a measure of reactive strength and stretch-shortening cycle utilization. The exact formula may vary by jump type but generally relates jump height to contact time (countermovement jump) or drop height (drop vertical jump).

Use Cases

  • Reactive strength assessment
  • Plyometric capacity
  • Drop jump and countermovement jump evaluation
