CORRECT ANSWERS
Most risky deviation from neutral/ midline stabilization
loss of neutral spine during movement
Core to Extremity movements
a sequence of muscular contraction beginning w/ large force producing, low velocity muscles of the
core and hips and ends w/ small force producing, high velocity muscles of the extremities
Muscles more likely of injury
smaller muscle groups and tendons/ligaments
Balance about the frontal plane
athletes movements accommodate the object and may or may not be characterized by straight lines;
frontal plane divides athlete into anterior/posterior halves (bisects athlete at mid foot
Posterior chain
hamstrings, glutes, spinal errectors
Posterior chain engagement
balance of pressure btw balls of feet and heels; creates increased power generation, helps keep knees
in line w/ toes, promoted midline stabilization and balance about frontal plane
, Sound hip function
athletes ability to flex & extend hip to maximize contribution to movement
Major safety issues w/ slow or incomplete hip extension
none
Poor hip function
muted hip, lack of hip extension, slow hip extension
muted hip
never closes/flexes; permanently open hip
Active shoulders
scapular position & stabilization, applying force in direction opposite the load
Full ROM about a joint
allows greater compliment of musculature to be used, preserves joint health, flexibility and strength
Effective stance/ grip
hand & foot position during a movement
When to use narrow stance
