Greg Lehman – Show Notes

In this episode, Greg Lehman and I discuss spine biomechanics and considerations for lifting kinematics. Greg is a Physiotherapist, Chiropractor and Strength and Conditioning Specialist from Canada who runs educational courses around the world. You can read more about him, see some more of his thoughts and view his course schedule on his website.

Key papers highlighted:

Spinal flexion in common exercises:

The Lumbar and Sacrum Movement Pattern During the Back Squat Exercise

Kettlebell swing, snatch, and bottoms-up carry: back and hip muscle activation, motion, and low back loads.

Effects of load on good morning kinematics and EMG activity

Comparison of different strongman events: trunk muscle activation and lumbar spine motion, load, and stiffness.

Stoop or squat: a review of biomechanical studies on lifting technique.

Using verbal instructions to influence lifting mechanics - Does the directive "lift with your legs, not your back" attenuate spinal flexion?

Regional changes in spine posture at lift onset with changes in lift distance and lift style.

Analysis of squat and stoop dynamic liftings: muscle forces and internal spinal loads

How to lift a box that is too large to fit between the knees

Forces acting on the spine:

Posture and the compressive strength of the lumbar spine.

Bending and compressive stresses acting on the lumbar spine during lifting activities.

Examination of a lumbar spine biomechanical model for assessing axial compression, shear, and bending moment using selected Olympic lifts.

Reduction in anterior shear forces on the L4L5 disc by the lumbar musculature

Transfer of loads between lumbar tissues during the flexion-relaxation phenomenon.

In vivo loads on a vertebral body replacement during different lifting techniques
