Drills

The first drill is skating while balancing on one leg.  Most ice skating moves involves being able to skate and balance comfortably on one skate.  This is a simple drill that involves flexing one knee about 90 degrees and abducting the shoulders about 90 degrees.  Abducting of the shoulders is not necessary, but helps with balancing and distributing the center of gravity.

Video of Shoot the Duck

Preperation

The first part of the preperation is the acceleration.  This is when the skater accelerates to a fast enough speed to successfully do the move.  Shoot the duck is only able to be down while moving on the ice.  The velocity is what helps the skater with most of the balance needed to complete the move.  Without movement on the ice (speed), the skater will fall, regardless of the skater's body position. 

After skater is accelerating at a speed needed for the move, the skater has to:

Hip and knee -  Flex knee and hip flexors about 90 degrees so center of gravity is very low to the ground.  Extend right knee so entire leg is parallel to the ground.  Start arms and hands in neutral position, flex shoulders bilaterally until they are parallel to the ground. Grab and hold onto distal part of leg as close to the ankle as possible.

Hip joint - Flexion of the hips bilaterally using the Iliacus, Psoas major and minor, Rectus femoris, Sartorius, Pectineus bilaterally and the Tensor fasciae latae.
Knee joint- Flexion of the knees bilaterally using the Sartorius, Semitendinosus, Semibranosus, and Biceps femoris.
Knee joint - Extension of the dexter knee using the Rectus femoris
Shoulder girdle -  Elevation/upward rotation Serratus Anterior, Trapezius upper and middle fibers, Rhomboids and Levator scapulae.  Abduction (protraction) of the Serratus andterior, and pectoralis minor.

Shoulder joint - Flexion of the Anterior deltoid and upper pectoralis major. Horizontal adduction of the Pectoralis major, anterior deltoid and coracobrachialis.

Elbow joint -  Arm starts in anatomical position, so the (elbow) - Triceps brachii long, lateral, and medial head, and Anconeous are held in extension.

Execution





hip and knee - Isometric hold of the  bilateral hip flexors, sinster knee flexor and dextor knee extensor.
Hip flexor muscles used in isometric hold are Iliacus, Psoas major and minor, Rectus femoris, Sartorius, Pectineus, and the Tensor fasciae latae.

Knee joint - Knee flexors used in isometric hold are the Sartorius, Semitendinosus, Semimembranosus,  and the Biceps femoris.
Knee joint - Knee extensors used in isometric hold are the Rectus femoris.

Shoulder Girdle - Isometric hold in abduction (protraction) position of the pectroalis major uper fibers,  Deltoid anterior fibers, Deltoid middle fiers, Deltoid posterior fibers and the supraspinatus.  Isometric hold of the levator scapulae, serratus anterior, upper and middle, and rhomboids in the elevated upward rotation.   Isometric hold of the pectoralis major upper fibers, deltoid anterior, middle  and posterior fiibers and the supraspinatus in abduction(protraction) position.

Shoulder joint -  Isometric hold of your shoulder flexors and horizontal adductors for at least 10 seconds.
Shoulder flexors held in isometric hold are Anterior deltoid, and Upper pectoralis major.
Shoulder adductors held in isometric hold are Pectoralis major, Anterior deltoid and Corocobrachialis.

Elbow joint  -  Even though the shoulder adducts, the elobow joint holds in extension isometrically.
Elbow extensors held in isometric hold are the Triceps bracchii long, lateral and medial head and Anconeous.

Recovery

hip and knee - Flex sinster knee so blade of skate is gliding on the ice alongside the other foot.  Bilaterally extend knees and hips until body returns to the upright position.

Knee joint - Flexion of sinster knee using the Sartorium, Semitendinosus, Semimembranosus, and Biceps femoris.
Knee joint -Extension of knees bilaterally using the Rectus femoris.
Hip joint - Extensioon of hips bilaterally using the Adductor magnus, Semitendinosus, Semimembranosus, Gluteus maximus and Biceps femoris.

Shoulder girdle - Doward rotation (depression) of the Pectoralis minor, Trapezius lower fibers.  Adduction (retraction) of the middle and lower trapezius, and rhomboids.

Shoulder Joint - Extension of the Latissimus dorsi, teres major, lower pectoralis major, posterior deltoid.  Horizontal abduction of the middle and posterior deltoid, infraspinatus and the teres minor.

Elbow Joint: -  Even though the shoulder joint adducts, the elbow joint holds isometrically in extended position.
Elbow extensors used are Triceps brachii long, lateral and medial head and Anconeus.
