“Screening the Lumbopelvic Muscles for a
Relationship to Injury of the Quadriceps,
Hamstrings, and Adductor Muscles Among
Elite Australian Football League Players
Sampling of Conclusions




“An association between multifidus muscle size (relative to
age, height, and weight) and preseason injury suggests a
way to identify players at risk of severe HGT injuries.
“Small multifidus muscle size at L5 through MRI predicted 5
of 6 players who incurred a more severe HGT injury, but No
relationship was found the ability to contract the transverse
abdominis muscle through the drawing in of the abdominal
wall.”
“People with LBP have delayed recruitment of the
Transversus Abdominis with upper and lower extremity
movement.”
“Hides et al does note that a previous report showed AFL
players with groin pain also had delayed activation of
Transversus Abdominis.”

Identifying the true core
weakness
Diaphragm – Top of cylinder
 The
core slings are
our window into
where the core is
actually weak,
typically it is not the
entire cylinder,
especially if you
catch the injury in
its early stages.
Muscle Slings according to
“The Janda Approach” text
Diaphragm
 Noted
in European Medicine since 1930s
movement and stabilization
across multiple joints!”
 Facilitate rotation
 Transfer forces through the trunk
 Interconnected – one muscle insertion is
connected to the next muscle’s origin via
a common keystone structure.
 Fixation points = stability for the chain
