Okay, but we don't have any old stuff for the paper today because we've got a new publication from 2026 in the Journal of Sports Sciences.
This is single joint posterior chain isometric testing using force plates, a systematic review of the methodologies and reliability of testing methods.
So this is a, as it sounds like, systematic review on a relatively new form of testing in sports science and performance, the single joint posterior chain isometric test, which is kind of named that as a general umbrella because there are a lot of different setups and ways that people are using uniaxial plates to test posterior chain isometric strength.
Um, probably some of the common ones that you might see are like somebody set up in a bridge based position and there's something blocking the hips and they're pushing down on the plate.
You may see, um, the plate being elevated up on a box and kind of like a hamstring bridge set up and it's an isometric push.
So the test that they ended up finding in the systematic review where we ended up in figure two here demonstrate all of these it's The 90-90, which is like a 90-90 hamstring bridge setup where the force plate is elevated up on plates, supine position, hip at 90, knee at 90, as kind of like a hamstring pull movement.
The 30-30 test, which is the same setup, but 30 degrees hip flexion and 30 degrees of knee flexion.
The standing 90-20 test, which is having the plates elevated even higher as somebody is standing hip at 90 degrees, knee at 20 degrees.
And then the hip extension, which is basically any form of like a ground-based bridge, long lever bridge into a force plate.
