When presented with the goal of making a change in a complex system (human), we have to consider where in the system we can intervene to promote the desired change. There are two types of feedback loops that are important to consider: Balancing feedback loops and reinforcing feedback loops. Balancing feedback loops are self-correcting. For […]

My Incredibly Biased Review of The MetaShred Diet by Michael Roussell, PhD
From my Black Casebook: I need to start this review by being fully transparent. Michael Roussell, PhD is my friend. I get to call him Mike. We’ve been friends for 10 years since we both spoke at the JP Fitness Summit and sat next to each other at lunch. I made sure that my lunch […]
From my Notebook: Complexity and Constraints
“The only model of a complex system is the system itself.” – Gell-Mann The problem with human-based physical therapy research is that they keep using humans for subjects. – Me Problem: Humans are complex adaptive systems, so the system is modified by behaviors. (Newton’s 2nd Law puts us at a different starting point at every […]
From my notebook: On Stability
Perceived threat to a self-organizing system will result in simplification of the system to reduce degrees of freedom and response time while simultaneously sacrificing adaptability. Humans will shift into the sagittal plane to reduce the degrees of freedom to simplify movement creating a more stable state. This will reduce system complexity and cortical effort and […]
IFAST University Strength & Conditioning Coach Interviews
We had Joel Jamieson at IFAST recently to teach his BioForce Certified Conditioning Coach Course. I took advantage of all the brain power in the room and took a great group of coaches into the purple room for some quick hitting Q & A segments. Each interview is only a few minutes, but they are […]
