Normative data helps you understand an athlete’s performance in context. The classifications make it easier for coaches and athletes to identify strengths, highlight areas for improvement, and track development over time.
Our normative dataset uses the following brackets:
Sex: Male / Female
Age Bands: Youth (Under 18), Adults (18+)
Performance Levels: Developing, Average, Above Average, Advanced, Elite
Drop Jump
The Drop Jump evaluates your reactive strength - your ability to rapidly absorb and re-produce force using the stretch-shortening cycle. Stepping off a box, you land and immediately perform a maximal vertical jump, aiming to keep ground contact time as short as possible while achieving maximum jump height.
Your performance is captured through Reactive Strength Index (RSI), calculated as:
RSI = Jump Height ÷ Ground Contact Time
A higher RSI indicates better reactive strength and a more efficient transfer from landing to take-off. The Drop Jump provides a reliable, high-quality measure of how effectively you can transition from braking to propulsion - an essential component of elite performance.
