Same Man, Same River (same learner, same task) – Never happens in life or rehabilitation

This quote, attributed to Heraclitus, remains relevant today – and relevant in the face of what we do in rehabilitation. We effect change on the movement systems.

In approximately 497 BC, Heraclitus is reported to have said, “No man ever steps in the same river twice, for it’s not the same river and he’s not the same man.”

Today, I will offer a complementary quote, “Intensity will always mean different levels of exertion, numbers of repetitions, time under tension, cognitive load, and frequency of “wins”/success to each person. The person being trained will not even rate the same levels of exercise or task as exactly the same, as they fatigue deeper into a session, or return back more skilled and informed. A patient, subject, client, athlete or customer – once changed by practice and conditioning, illness or injury, aging or experience, is never the same person that they were.”
