Force plate result vs weightlifting result

[Elle]

A coach I know borrowed a force plate (and its accessories) from his physiotherapist and tested his athletes on october 2024. Nice! His athletes are growing well in terms of weightlifting results but the new tests, made a week ago, reported a worsening of all tests.

How would you go about it? Would you stick with the program until the athletes improved or would you modify it to try to improve those tests?

The tests are:
Jump (peak force)
Isometric mid thigh pull (peak force)
Legs abduction and adduction (with a sort of dynamometer sold with the force plate)
Leg extension

I don't know how the test were conducted but there was the help of the physio.

Don't know. My first instinct would be miscalibration of the force plates or improperly run tests.

The other option is difference in fatigue level, especially completed at the start or end of a session.

IMTP tends to correlate okay with general improvement in pulling and squatting strength. Leg extension/hip abd,add decreasing would be unusual with better training results and increased test familiarisation. Jump peak force could increase or decrease for multiple reasons.

This could also be an example of how laboratory measures may not exactly correlate to real world results. But like strapping said, maybe residual fatigue impacted the results too. I do believe many of these tests are performed after a week or so of near complete rest or cessation from training in order to "calibrate" the body.
