Movement Debrief Episode 109 is in the books. Here is a copy of the video for your viewing pleasure, and audio if you can't stand looking at me.

Here is the setlist:

• What are normal scapular movements during respiration?
• Are these scapular respiration movements paired together as we move?
• Is passive exhalation a thing?
• What are the primary compensatory scapular positions for a wide and narrow ISA?
• What happens if further compensatory activity occurs?
• What type of compensatory strategy is a swayback posture utilizing?
• What are the best ways to gain proximal hamstrings to elicit a posterior pelvic tilt?
• How would you test whether a client needs inferior or superior posterior thorax expansion?

Respiration Revisited

Here is rockback breathing, a great way to encourage a posterior tilt

Here is the drunken turtle. You are getting a passive posterior tilt, but it's a great dynamic activity to drive spinal inhalation

A great squat variation to get proximal hamstring is the chair and wall squat

If you want to learn more about squatting, check out my deep dive.

Here is a picture of the subscapularis. Note the differences in fiber direction based on location:

Scapular Respiratory Mechanics (1:09)

When talking about respiratory scapular respiratory mechanics, do these mechanics INHaled scaps are ABD, ER, DownRotation, Posterior Tip Do those 4 movements ride together always with regard to a trainer's eye? To say a different way, If I protract/reach and Inhale in mid propulsion, like a pushup position... I should have abd/ER/DownRotation/PosteriorTipping all riding together?

Upward Rotation (8:48)

Thank you for the response! Could you explain how upward rotation is part of exhalation mechanics? I’m trying to visualize it but I’m having trouble connecting all the dots

Passive Exhalation (12:57)

Is passive exhalation a thing?

Compensatory Scapular Mechanics (14:12)

Hey Zac! Could you possibly talk about the compensatory scapular movement for narrow and wide ISA? For example, narrow ISA tends to have anterior compression first, how would this impact scapular movement? I can’t seem to quite understand this. Thank you!

Swayback and Respiration (25:06)

Would you consider someone with a swayback posture using an inhalation or exhalation strategy?

Pelvic tilts for Hip Internal Rotation (26:14)

How do you get hamstrings to engage to greater influence posterior pelvic tilt, which would greater influence femoral internal rotation?

Differentiating Posterior Thorax Expansion (28:25)

What is your go-to test to differentiate whether a client needs inferior or superior posterior ribcage expansion? They probably lack humeral ER in both situations if I understand correctly. Thank you!

Sum Up

• Normal scapular mechanics assume a "uniform" expansion in all directions of the thorax.
• Movement inherently biases air to go in certain areas of the thorax, changing the paired mechanics.
• Scapular upward rotation is associated with exhalation because the upward rotators compress the thorax.
• Passive exhalation typically occurs with quiet breathing; different than breathing that intends to restore movement options.
• Narrow infrasternal angles have thoraxes with increased volume posteriorly and more anterior compression; leading to an abducted and internally rotated scapula. More humeral internal rotation-based measures would be limited
• Wide infrasternal angles have thoraxes with increased volume anteriorly and more posterior compression; leading to an adducted and externally rotated scapula. More humeral external rotation-based measures would be limited
• A swayback is using an inhalation strategy, hence the increased thoracic kyphosis
• Using deeper hip flexion can better recruit the hamstrings when choosing activities for posterior pelvic tilting
• Posteroinferior thoracic expansion is needed with loss of shoulder external rotation at 90 degrees abduction
• Posterosuperior thoracic expansion is needed with loss of shoulder external rotation a 0 degrees abduction or horizontal abduction
• Shoulder flexion limitations can signify total posterior expansion (above 120 flexion needs upper thorax, less than needs mid to lower)
