The Biomechanics of Performance

Biomechanics is an essential area of rehab and performance that every coach and clinician should understand, but there is one BIG problem. Ever pick up a biomechanics book? If you’ve so much as peaked at one, you probably saw a ton of technical jargon, physics, mathematics, and endless equations. While the fancy equations might be useful for researchers, coaches need a working knowledge of a few biomechanics principles to really make that knowledge useful in the gym. So, cut out the equations, and grasp the concepts. In this video series, we’ve done just that.

This 4 part video series will go through the core principles every coach should understand to make their training more effective, prevent injuries, and make better decisions when writing programs or adjusting things on the fly.

  1. Biomechanics and Coaching
  2. Essential Concepts for Coaching I
  3. Essential Concepts for Coaching II
  4. Biomechanics for Peak Performance


Part 1 – Biomechanics and Coaching

Here is what you’ll find in part 1 of the series:

  • Why mechanics matter in performance and rehab
  • A few prerequisite concepts you should know before getting too deep
  • The 3 laws of motion
  • Forces, forces, forces, and more forces
  • Basic mechanics of posture and squatting

Part 2 – Essential Concepts for Coaching

In video one, we went over the foundations of biomechanics including Newton’s laws and forces.

In this video, we get deeper into forces, start applying Newton’s laws, and get into the first two BIG biomechanics concepts that will change the way you think about movement. Once we’ve hammered home those concepts we will apply them to movement at various joints. Here’s what you will find in video two:

  • Internal vs. External forces. This includes those “ground reaction forces” that Ty is always talking about. And friction, which is so incredibly undervalued it’s sickening. I’ll give you “book definitions”, then a bunch of examples so you can relate this to what you intuitively know. This lets you look at things in new ways, connecting more dots in that big brain of your’s. Don’t worry, I drew a ton of arrows over pictures to make it simple. What are you trying to do with most training? Look at it through the lens of internal and external forces to really dissect your clients’ movement.
  • Length-Tension Relationship. A theory that strongly explains why position of the bones and muscles is so important. What reduces a muscle’s ability to contract? To produce force? Those two are not the same, by the way.
  • Torque & Newton’s laws (yes, again). This is the big topic I want to hammer home (no pun intended). What is a torque wrench? How does it work? How is it similar to muscles and joints? I try to avoid equations, but I wanted to show you the torque equation so you can understand the relationship between force and moment arms. Don’t worry, we don’t waste time on math and mathematical units. Understand the relationships. How does torque change through an exercise’s range of motion? How does torque change if you don’t have a patella? How can you change exercises on the fly? How do proper running mechanics optimize your torque?
  • Velocity and Acceleration. Linear vs. angular velocity. Centripetal forces and the hammer throw. We’ll work through a whole series of diagrams so you can understand how velocity and acceleration change during a squat. If you know this, you’re in a great spot. Feel free to play this back or work through it on your own. How would bands or change alter these pieces of physics?

Part 3 – Essential Concepts for Coaching Deux

After beating Newton’s laws, forces, and torque to death in the first two parts; we can get to the last two biomechanics concepts every coach needs to understand. In this video we clarify the impulse-momentum relationship and the work-energy relationship. After going though the “book definitions” of these concepts we walk through applying them to jumping, landing, throwing, and gait. This is the shortest video in this 4 part series, but by far the most dense.

Here is what your getting into:

  • A recap of velocity and acceleration
  • The impulse momentum relationship
  • The work energy relationship
  • How these relationships relate to one another
  • Practical examples for each concepts to clarify things
