The Followthrough

Phase 7- The Follow through:

After your arm decelerates across your body, the leg on the same side as your throwing arm will swing around and land about shoulders length apart from the opposite leg. You want to be balanced on the balls of your feet. After balanced on both feet, quickly bring your glove and hand up into a fielding position. This will allow for a quicker reaction off the mound if a ball is hit towards you.

Shoulder Girdle
The scapula on your throwing shoulder upward rotates with the use of the middle/lower fibers of your trapezius muscles. The scapula on your glove hand shoulder protracts using the pectoralis minor and serratus anterior muscles.

Shoulder Joint
Throwing Hand- Slight diagonal abduction of the shoulder joint by eccentrically contracting your posterior deltoid, infraspinatus, and teres minor muscles.
Glove Hand- Shoulder joint stays adducted by eccentrically contracting your latissimus dorsi, teres major, and lower pectoralis major muscles.

Elbow Joint
Glove hand elbow is slightly pronated by isometrically contracting your brachioradialis, pronator teres, and pronator quadratus muscles. Throwing elbow is flexed to about 30 ˚ by concentrically contracting both heads of the biceps brachii, brachialis, and brachioradialis muscles. It is then slightly pronated by isometrically contracting your brachioradialis, pronator teres, and pronator quadratus muscles.

Hip Joint
Both hip joints remain in a slightly flexed position by concentrically contracting your iliacus, psoas major and minor, rectus femoris, sartorius, pectineus, and tensor fasciae latae muscles, causing an anterior pelvic tilt.

Knee Joint
Both knees remain flexed by concetrically contracting your biceps femoris, popliteus, semimembranosus and semitendinosus.
