Early Cocking

Phase 2.

Early Cocking- Begins after the windup phase as your hands spread apart to form a T shape. At the same time, your front foot starts to go towards the target.

Shoulder Girdle
Both scapulas upward rotate using using your serratus anterior muscle and middle/lower fibers of your trapezius muscle.

Shoulder Joint
Abduction of both shoulder joints by concentrically contracting your supraspinatus, deltoid, and upper pectoralis major muscles.

Elbow Joint
Extension of about 170 ˚ by eccentrically contracting triceps brachii, and anconeus muscles.

Hip Joint
Non Throwing Leg causes the hip to extend and abduct.
It extends concentrically by using your semitendinosus, semimembranosus, biceps femoris, and gluteus maximus muscles.
It abducts by eccentrically contracting your gluteus medius and minimus, along with your tensor fasciae latae muscle.

Knee Joint
NonThrowing Knee starts to extend by concentrically contracting your rectus femoris, vastus intermedius, vastus lateralis, and vastus medalis.
The throwing knee stays externally rotated by isometrically contracting your biceps femoris muscle.
