Summary

This was one of the most enjoyable shows we’ve done all year. Really, really enjoyed speaking with Dr. Scott Lynn.

He earned a PhD in Biomechanics and is now an associate professor of Kinesiology/Biomechanics at Cal State Fullerton. Loosely put, biomechanics is the study of how forces effect your body (stress —> adaptation) as well as how the forces produced by your body effect the world (moving yourself and objects… in our case heavy barbells).

Want to know how front squats are different than back squats? Is there a difference in muscular activation? Is there a difference in the stresses on the hips, knees and lower back? Scott has you covered. Collecting, analyzing and interpreting this kind of data is exactly what biomechanists do on a daily basis (often using cool things like 3D motion capture systems like the ones used to make video games and animated movie characters).

In this episode Dr. Lynn teaches us:

Why scoring well on a movement screen could actually make you MORE likely to get hurt
How you can use “movement variability” to stay healthy and minimize injury
Why your lower back isn’t designed to “move under load” and how to avoid lower back pain
How he tests muscular activation in his laboratory

Enjoy!

-Mike and Doug

Barbell Shrugged helps people get better. Usually in the gym, but outside as well. In 2012 they posted their first podcast and have been putting out weekly free videos and podcasts ever since.

Along the way we've created successful online coaching programs including The Shrugged Strength Challenge, The Muscle Gain Challenge, FLIGHT, Barbell Shredded, and Barbell Bikini.

0:00.0	I've been doing academic research for a really long period of time and you do those studies
0:03.6	that sit in academic journals that nurse like Andy and I read sometimes and nobody else really.
0:09.2	And so I think to me taking that technology or that knowledge and getting into the hands of
0:14.9	the average person is I'm more excited about doing stuff like that now where I can get people
0:20.6	using these really cool tools that have sat in academic settings for a long time
0:24.5	and using them in a real life setting. So whether it's in the gym or on the golf course or wherever
0:30.4	that's the kind of stuff that I'm doing a lot of work on now is trying to take these tools
0:35.0	and make them useful to to every single person.
0:59.9	All right welcome to Barbel's truck I'm Mike Blitzer here with Doug Larson and Andy Galpin and we are
1:12.6	here at Cal State Fullerton visiting Dr. Scott Lynn. He's a biomechanist and which means you study
1:19.9	how the body moves and what's firing and what's not firing and how to fix it and basically I'll give
1:26.6	you that. Is this stretch? Yeah so it's basically the mechanics of a biological system is the
1:34.6	technical definition and mechanics is actually defined as the influence of force on body. So
1:39.2	really what we're studying is how forces affect and there's two ways of biomechanist we can do
1:45.2	things that look at the structure of the human body. Some people look at how forces affect
1:48.5	the cartilage in your knee or the discs in your back or the ligaments in your knee or whatever
1:53.2	and then you can look at how it affects your function. So how it makes you lift better and jump higher
1:58.4	and hit a golf ball further and all those types of things. So a lot of people do talk about it as
2:03.4	being just a study of motion but I think a lot of stuff that we do looks at the forces that go into
2:08.0	creating that motion. Newton told us that we can't produce force without an external or we can't
2:12.3	produce motion without an external force and most of us when we're walking around moving the only
2:17.2	thing we can push off of is the ground with our feet and so we're really that's a lot of the work
