L2 - Common movements themes

Common movements themes
Midline stabilization
Core to extrimity
Balance about the frontal plane
Posterior chain engament
Sound hip function
active shoulders
full ROM
Effective stance and/or grip
Relationship
Spine
Pelvis
Static
core strength
neutral spine
engaging
abs
obliques
internal
external
erector spinae
Torso rigid, integrated structure
injury if exposes to shear
secure when compressions
Deviations from natural
flexion
extention
Risk
Safest: neutral position
More: non-neutral in static
Most: Loss of neutral in motion (significant spinal flexion)
Common injuries L1-L5
Secuence
1. Large force, low-velocity muscles of the core (abdominals & spinal erectors) + hips
2. Small force, high velocity muscles (biceps, calves, wrist, etc)
Allow great work capacity
bicepcts mid foot
successful task especially as the loading increase
Also refer in the kipping
Posterior chain group of
increase power
base to transmit forces
keeps the knee in line with toes
Muscles
tendons
ligaments
Risk
midline stabilization
Risk
midline stabilization
by itself is not terrible risky
Pressure in the feet
lack -> shift excesively forward of the frontal plane
Knee position
fault -> inward
Risk
hip ability to
Flex
Extend
Applies more force
Most elevation
Poor hip function
Muted hip
Lack of extension
slow hip extension
never closes
provide stable position
scapular position
weightlifting
gymnastics
