Which jump metrics should I choose?

This article highlights 4 categories of jump metrics you should be using to help assess performance overtime.

  1. Choose 1-2 Output metrics - what is an obvious performance output?
    • Examples: Jump Height, Take-Off Velocity, Peak or Average Velocity, Jump Momentum
  2. Support these with 1-3 Driver metrics - what drives the task?
    • Examples: Average Braking Force, Average Propulsive Force, Force at Lowest Displacement
  3. Try to identify 1-3 Strategy metrics - what strategy is your athlete using (knowingly or otherwise)?
    • Examples: Braking Phase Duration, Propulsive Phase Duration, Time To Take-Off (how long did the jump take?), Countermovement Displacement (how far down did the athlete go?)
  4. Interested in looking at symmetry? Include 1-3 Symmetry Metrics - what is the difference in output between left and right limbs?
    • Examples: L/R Average Braking Force (our favorite), L/R Average Landing Force, L/R Average Propulsive Force, L/R Average Braking Impulse Index
  5. Are Fluffy metrics needed? If so, how? How will these help support your assessment? If, and this is an important if, you have a scientifically robust rationale for including fluffy metrics then choose 1-3.
    • Examples: Peak Power, Average Power, Average Braking Rate of Force Development
