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, pronatorteres • Shoulders R and L- *Horizontal abduction of R- Deltoid middle fibers, deltoid posterior fibers, lattisimusdorsi, 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 carpiradialislongus, Extensor carpiradialisbrevis, Extensor carpiulnaris • Hand R and L flexion- Flexor digitorumsuperficialis, flexor digitorumprofundus, flexor pollicislongus

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
