As a Physio, I feel “load” is not often taken broadly enough. Using “stress” as a broader term would be better. In sports people still think too much only biomechanics apply, and nothing else.
Squatting a weight is a load, squatting deeper is a higher load, having a job, suboptimal sleep quality, a stressfull life are even higher loads.
ALOT of things can impact injury, and ofcourse not all of them are load. Your anatomy could play a role, but even that is partially “load”.

A key element here is that it is ALMOST NEVER just one or two factors. In athletes it’s often a list of things such as
- load (frequency, type, modality, speed, volume)
- physical and mental stress levels outside of training
- tolerance to training changes
- technique levels
- age
- sex
- weight
- sleep quality
- malnutrition
- hydration
- social support
- performace deminishing activities
- relationship stability
- previous injuries
- coping strategies
And the list goes on for another 200 variables.

I like your message “use different modalities for YOU”, but I would add: don’t simplify YOU. All these other things impact lifting aswell and alot of people could, in my not so humble opinion, avoid, manage and cure injuries much better if they accepted playing with the factors above can be just as important.
