2. Baseball Swing Video

3. Equipment Needed… Primary: Bat Baseball Secondary: Glove Home Plate
Cleats
Helmet
Batting Gloves

4. General Rules… Batter must stay within the batter’s box
There are 4 balls and 3 strikes allowed per batter
*Swing and a miss= strike
*Foul ball= strike (Can’t strike out if foul ball=3rd strike)
*Ball=outside of strike zone
*4 balls= batter allowed to advance to 1st base
*batter hit by pitch= allowed to advance to 1st base

5. Constraints…
If the batter steps out of the batter’s box, the pitcher must wait to pitch the ball
Foul balls (as mentioned previously)= count as strikes

6. Constraints ctd…
Batter must maintain control of bat during and after swing
If ball is fair, batter must lay bat down nicely next to plate
If teammate is attempting to steal while you’re at bat, depending where attempt is taking place, allow catcher appropriate space to make a play

7. Objectives…
To successfully contact the ball with the bat and put into play, with an attempt of avoiding defenders and reaching base safely.
To give best attempt at not striking out.
To provide teammates and yourself opportunity to score as many runs as possible.

8. Stages… Stance Stage (Right Handed)- Isometric Contractions
Feet shoulder width apart, toes toward home plate
Knees slightly bent R and L flexion- Biceps femoris, Popliteus, Semimembranosus, Semitendinosus
Glenohumerus R and L flexion- Biceps brachii short and long head, brachialis, brachioradialis, pronator teres
Shoulders R and L-
*Horizontal abduction of R- Deltoid middle fibers, deltoid posterior fibers, lattisimus dorsi, infraspinatus, teres minor
*horizontal adduction of L- Pectoralis major upper fibers, Pectoralis major lower fibers, coracobrachialis, deltoid anterior fibers
Wrist R and L Hyperextend- Extensor carpi radialis longus, Extensor carpi radialis brevis, Extensor carpi ulnaris
Hand R and L flexion- Flexor digitorum superficialis, flexor digitorum profundus, flexor pollicis longus

9. Preparatory Stage
Everything similar to Stance Phase minus trunk movements in preparation
R arm abducting
L arm adducting
Both arm movements going away from pitcher
Body slightly leaning backwards in preparation for pitch

10. Movement Stage
External and Internal Oblique perform counterclockwise trunk rotation
R hip Extends while L hip Flexion
R and L knees Extension
R and L ankles invert and plantar flexion
Trunk rotation counterclockwise
R shoulder Flexion while L shoulder Extension
R and L elbows are Extension
R wrist Supination and L wrist Pronation
Starts in left Cervical Rotation and finishes in right Cervical Rotation

11. Follow Through Stage
Follow through stage is very similar to the movement stage
Biceps

12. Recovery Stage
Most batters step out of the batters box following their swing.
They do not have a specific recovery stage besides getting themselves ready to go back in the preparatory stage.
If the batters make contact will place the bat on the ground and begin to run.

13. Most important Muscles to Strengthen and Stretch are: Hamstrings, Hips, Quadriceps, Abdominals, Chest, Forearms, and Shoulders

14. Injury Concerns…
Hit by a Pitch- Head Injuries (concussions and broken jaws)
Bruises or contusions
Pulled hamstrings often occur due to not staying ‘loose’
Shoulders injuries can occur due to unstable nature of shoulder joint
Patella Dislocation
