3Equipment Needed… Primary: Bat Baseball Secondary: Glove Home Plate CleatsHelmetBatting Gloves
4General 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
5Constraints…If the batter steps out of the batter’s box, the pitcher must wait to pitch the ballFoul balls (as mentioned previously)= count as strikes
6Constraints ctd…Batter must maintain control of bat during and after swingIf ball is fair, batter must lay bat down nicely next to plateIf teammate is attempting to steal while you’re at bat, depending where attempt is taking place, allow catcher appropriate space to make a play
7Objectives…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.
8Stages… Stance Stage (Right Handed)- Isometric Contractions Feet shoulder width apart, toes toward home plateKnees slightly bent R and L flexion- Biceps femoris, Popliteus, Semimembranosus, SemitendinosusGlenohumerus R and L flexion- Biceps brachii short and long head, brachialis, brachioradialis, pronator teresShoulders 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 fibersWrist R and L Hyperextend- Extensor carpi radialis longus, Extensor carpi radialis brevis, Extensor carpi ulnarisHand R and L flexion- Flexor digitorum superficialis, flexor digitorum profundus, flexor pollicis longus
9Preparatory StageEverything similar to Stance Phase minus trunk movements in preparationR arm abductingL arm adductingBoth arm movements going away from pitcherBody slightly leaning backwards in preparation for pitch
10Movement StageExternal and Internal Oblique perform counterclockwise trunk rotationR hip Extends while L hip FlexionR and L knees ExtensionR and L ankles invert and plantar flexionTrunk rotation counterclockwiseR shoulder Flexion while L shoulder ExtensionR and L elbows are ExtensionR wrist Supination and L wrist PronationStarts in left Cervical Rotation and finishes in right Cervical Rotation
11Follow Through StageFollow through stage is very similar to the movement stageBiceps
12Recovery StageMost 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.
13Most important Muscles to Strengthen and Stretch are: Hamstrings, Hips, Quadriceps, Abdominals, Chest, Forearms, and Shoulders
14Injury Concerns…Hit by a Pitch- Head Injuries (concussions and broken jaws)Bruises or contusionsPulled hamstrings often occur due to not staying ‘loose’Shoulders injuries can occur due to unstable nature of shoulder jointPatella Dislocation
