I heard in this interview of Jill Cook (tendon researcher) on https://youtu.be/GKkSp-TlofI?t=230:
Tendons talk to you 24 hours later. So what happens if if I put load on a tendon today, it will tell me tomorrow it's been happy with the load.
Why does it take 24 hours for tendons to give feedback on whether the loads they received were excessive?
