Are we building fitness and skill on top of dysfunction?
What is the FMS?What is the FMS?
• A series of movements designed to evaluate A series of movements designed to evaluate stability and mobility (i.e. functional movement)stability and mobility (i.e. functional movement)
• Uses extreme positions where weaknesses and Uses extreme positions where weaknesses and imbalances become noticeableimbalances become noticeable
• Ultimate goal is to identify athletes at increased Ultimate goal is to identify athletes at increased risk for injuryrisk for injury
Key PrinciplesKey Principles
• Optimum functional movementOptimum functional movement– Balance between mobility and stabilityBalance between mobility and stability
• Tightness = weaknessTightness = weakness– Example :Example :
» Hamstring seemingly become tight when the core is Hamstring seemingly become tight when the core is too weak to control the pelvistoo weak to control the pelvis
» Targeting the tightness only will result in a short Targeting the tightness only will result in a short term gain at bestterm gain at best

Asymmetry
• musculo-skeletal asymmetry is a well established risk factor for injury

flexion and abduction of the shoulders
DEEP SQUATRequires:
mobility :
ankle, knee, hip, thoracic spine, and shoulders
stability :
core in symmetrical stance
DEEP SQUATUpper torso is parallel
with tibia or toward vertical
Femur below horizontal
Knees are aligned over feet
Dowel aligned over feet

flexion of the knee and hip
adequate balance-dynamic stability
HURDLE STEPRequires:

closed chain hip extensioncore stabilization to maintain adequate balance in single leg stance
HURDLE STEP
Hips, knees and ankles remain aligned in the sagittal plane
Minimal to no movement is noted in lumbar spine
Dowel and hurdle remain parallel

SHOULDER MOBILITYRequires:
shoulder mobility in a combination of motions including
abduction/external rotation, flexion/extension, andadduction/internal rotation
scapular and thoracic spine mobility.
SHOULDER MOBILITY Fists are within one
hand length
(Assume one hand length is 8 inches)

ACTIVE SLRRequires:
functional hamstring flexibility, which is the flexibility that is available during training and competition
(this is different from passive flexibility, which is more commonly assessed)
adequate hip mobility of the opposite leg
lower abdominal stability
ACTIVE SLRRequires:
Mobility :functional hamstring flexibility, which is the flexibility that is available during training and competition(this is different from passive flexibility, which is more commonly assessed)adequate asymmetrical hip mobility
Stability : lower abdominals
ACTIVE SLR• Ankle/Dowel resides
between mid-thigh and ASIS

TRUNK STABILITY PUSH UP
requires:symmetric trunk stability in the sagittal plane during a symmetric upper extremity movement
(Many functional activities in sport require the trunk stabilizers to transfer force symmetrically from the upper extremities to the lower extremities and vice versa)
If :the trunk does not have adequate stability during these activities, kinetic energy will be dispersed and lead to poor functional performance, as well as increased potential for micro traumatic injury
TRUNK STABILITY PUSH UP
Males perform one repetition with thumbs aligned with the top of the forehead
Females perform one repetition with thumbs aligned with chin
ROTARY STABILITYRequires:
asymmetric trunk stability in both sagittal and transverse planes during asymmetric upper and lower extremity movement
ROTARY STABILITYPerforms one correct
unilateral repetition while keeping spine parallel to surface
Knee and elbow touch
