Countermovement Jump Assessment for ACLR Athletes
For the vast majority of ACLR athletes I manage, this will be the first time ever working with them.
For that reason I won't have a database of their previous best strength and performance tests (eg. hop, jump, sprint, fitness tests).
And neither will they..
So what Ive been using a lot lately during late stage rehab, and to help me guide return to full training and sport, are normative values from existing research to see what their current performance standards are.
It's far from perfect, and care does need to be taken when generalising the data from one group of normal athletes to the person you're testing, but I find it helps me understand where the person is at, and their readiness to return to high demand activities.
If you're interested, here are some other CMJ norms I've come across:
35-37cm male school children (15-18yrs)
26-28cm female school children (15-18yrs) Reference: Ramírez-Vélez et al 2017
46-50cm elite male volleyball players (24-26yrs) Reference: Borras et al 2011
This is just the tip of the iceberg of what's out there and if you're interested in going down a rabbit hole, PubMed is a great place to explore
