when the associated scapular motion is performed with shoulder motion. With motion and
resistance from overhead, scapular depression is required. For the arm to return to the start-
ing position overhead the eccentric action of the lat must be accompanied by the scapular
rotation of scapulohumeral rhythm.
• Associated Muscles - The lower fibers of the trapezius are responsible for scapular
depression. Slight retraction is always associated with scapular depression as the lower
fibers of the trapezius angle downward and toward midline, attaching on the spine. The long
head of the triceps is involved in shoulder extension and adduction, although change in its
length is limited when elbow flexion coincides with shoulder motion. The biceps,
brachioradialis, and brachialis are always involved in pulling movements as elbow flexion is
required. The degree of their individual involvement depends upon radioulner joint position.
The Positioning
• Adjust the thigh pad to allow access and stabilize
the body.
• Check the weight to insure that the appropriate
resistance has been selected. Body position and
control of the motion should never be compro-
mised by excessive weight.
The Motion
• Grip the narrow/parallel handles.
• Lean back slightly at the hips and maintain.
• Depress the scapula (pinch the shoulder blades
down and back).
• While maintaining the scapular position, bring the
handles down in front of the face an elbows beside
the body.
• Slowly return to the starting position overhead by
allowing the scapula to move as needed, but with-
out resting.
• Reset the scapula at the beginning of each
repetition.
