Module 7 - Rotational Driven Running Flashcards
Intervertebral disks of the spine are not for shock absorption but rather to _________.
Store and unload energy via torsion of the spine
What is spinal torsion?
The twisting of the spine
What does ASSS stand for?
Anterior spiraling spring system
What does PSSS stand for?
Posterior spiraling spring system
The ASSS comprises of which muscle groups?
External Oblique
Abdominal fascia and external oblique aponeurosis (tendon sheath)
Contralateral Internal Oblique
Contralateral Adductors
The PSSS comprises of which muscle groups?
Latissimus Dorsi
Fascia of the thoracic and lumbar spine region
Contralateral Glute Max
Contralateral Biceps Femoris
These spiraling spring systems (PSSS and ASSS) gain and release energy via the _______________.
stretch-shortening cycle.
The degree of hip rotation directly correlates to what?
To the degree of rotation of the torso and, more specifically, the shoulders.
if your athlete under or over-rotates the hips, where is a good starting place and why?
The shoulders. By instructing your athlete to increase or decrease rotation of the shoulders, it is likely you can directly affect the rotation of the hips.
What is an effective way to cue runners who under-rotate their torso while running?
To have them focus on moving their shoulders forward while running.
What does shortening one’s stride refer to?
This refers to reducing one’s stride length in front of the body, not behind it.
If you have athletes who run with a very short posterior stride and/or prematurely lift their heel during their posterior stride (or always run on their forefoot), a lack of adequate _________________ may be the culprit.
Ankle dorsiflexion
