STANCE AND SWING PHASES OF
RUNNING.
STANCE
SWING
GOOD RUNNING FORM: what to
look for?
Minimal vertical displacement
Cadence
Lean forwards from the ankles
Foot strike beneath body
Compact arm positioning
Relaxed shoulder girdle
COMMON TECHNIQUE FAULTS
Component
Fault
Correction
Trunk
incline/general
posture
•Excessive trunk lean forwards
or backwards
•General posture e.g.
overextended
•Slight forward inclination
•“Imagine running into a stiff
breeze”
•“Ribs down”
•“Chest out”
Arm swing
•“Opening up” arm swing:
arms > 90 degrees, or away
from body
•Hand grip tight
•Arms close to body around 90°
•“Hands to pockets”
•“Potato chip hold”
Hip
flexion/extension
•Inadequate or poorly timed
hip flexion/extension
•Paw-back
Stride length
•Over-striding: initial foot
contact in front of body’s
centre of gravity
•Land with feet under body
•Correct cadence
FUNCTIONAL IMPAIRMENTS:
POSTERIOR VIEW
•
Pelvis/hip/knee:
•
•
•
•
•
Pelvic heights
Femoral rotation
Hip/knee angle
Trendelenberg – a weakness of hip
abductors (gluteus medius/minimus) on one
side causing contra-lateral lateral drop of
pelvis
Foot/ankle:
•
•
Normal pronation is 6-8 degrees with resupination
Over pronation of ankle/foot – a rolling out
of the heel relative to the leg +/- a collapse
of the arch, leading to late re-supination for
push-off
FUNCTIONAL IMPAIRMENTS:
LATERAL VIEW
Pelvis/hip:
Normal anterior/posterior tilt – 11° anterior
rotation, 15° with leg extension
Excessive anterior tilt of pelvis –muscle
imbalances of the hip flexor/extensor muscles,
reduced core control
Knee:
Excessive knee flexion in land
Poor strength/co-control of quads/hamstrings
Foot/ankle:
Dorsiflexion control
Listen for “foot slap”
Reduced control often from calf tightness +/tibialis anterior weakness/poor control
COMMON RUNNNG INJURIES
Component
Common diagnoses
Possible impairments
Spine
• Non Specific Low Back Pain
(NSLBP)
• SIJ pain
• Pelvic dysfunction
• Rib pain/subluxation
• Poor TVA/Oblique ratios
• Imbalance through oblique slings
• Hypomobile spinal segments
• Poor spinal awareness
•Tight and short H/S/QL/ES
Hip
• Gluteal tendinopathy
• High hamstring tear/ensethop’
• Femoroacetabular imp’
• Labral tears
• Weak glutes (Neuro/Strength)
• Tight ITB/Overactive TFL/ADD
• Overactive and short H/S
• Poor ant oblique sling co-ord
Knee
• PFPS/ITBFS
• Degenerative meniscal tears
• Patella tendinopathy/bursitis
• a/a
• Weak or poorly timed VMO
• Poor patella position/movements
Foot/Ankle
• Plantar fasciitis
• Achilles/Peroneal/Tib Post
tendinopathies
• Poor arch control/support
• Poor footwear for level of intrinsic
foot strength
• Tight calves
• LL biomechanic (check a/a)
