Transcript of Softball Fast Pitch Presentation

Objectives Softball Fast Pitch By:Anna Hilton
Kristen Kliemisch
Marino Pignataro
- Name the muscle groups that function to position and move upper and lower extremities with the pitch.
-Have the ability to understand the mechanics and kinetics of the windmill softball pitch
-Identify the six different phases The students will be able to: Introduction 6 o'clock Ball Release 3 o'clock 9 o'clock 12 o'clock We're going to talk about the
break down of the windmill
pitch in softball, and ways to
modify it in a
physical education setting. Follow-Through Windup http://www.denvillesoftball.org/cc_fundamentals_pitching.html How does this
relate... Weight Training
Exercises How can you
adapt this skill
for special education. How can you teach
a child who is
performing poorly Remind them one-on-one
of the cues which were
given to help remember
the three main body
positions for the throw. Talk with the student
one-on-one again
to see what they were
struggling with,
and demonstrate it
for the student again. Break information down
into segments
to help them learn
piece by piece Single Leg Squat
or
Split Stance Squats Lunge with Upper
Body Rotation Shoulder Flexion
Laying Flat on
Stomach Use a different
type of ball
Peer Assistance References: http://www.livestrong.com/video/3427-fastpitch-softball/ If several students
are struggling;
Stop class and go over
again but break it down
and present it to them slower Relate it to
something they
know For Example: Denville pal girls' softball. (n.d.). Retrieved from

kick the bad guy,
end with a punch This phase is to generate momentum before the pitch

Shift weight to ipsilateral leg

Continuous movement

Throwing arm is usually internally rotated or neutral In this stage the Anterior Deltoid, Pectoralis Major,
Serratus Anterior, and Bicep are at their peak of activity. In this stage the Anterior Deltoid, Pectoralis Major, Serratus Anterior, Biceps, Supraspinatus, Infraspinatus, Posterior Deltoid, and Teres minor are at their peak of activity.

Immediately after ball release arm makes contact with lateral hip and thigh.

Throwing motion of shoulder continues further into flexion.

Body continues to move forward untl the body's center of mass is over the stride leg.

Low muscle activity in upper extremity compared to baseball fast pitch.

Elbow flexors continue to flex the elbow.
Shoulder flexors and adductors move the arm across and up the front of the body.
The wrist continues to flex in it's follow through.

Stride leg holds entire body weight.
Hip and Knee extensors are primary muscles, working with hip abductors to
stabilize body over leg

Back and abdominal muscles work to maintain upright position of trunk.

Hip flexors of pivot leg lift the extremity upwards. ie: bigger, softer Stride leg: hip flexion and knee extension

Ipsilateral leg: gluteal muscle contraction

Triceps activate

Scapular stabilizers activate ->
increasing humeral elevation Pitchers arm reaches limit= TOB (top of backswing)

Pitchers stride foot may contact ground
before TOB

Humerus is externally rotated

Posterior deltoid, infraspinatus, and teres minor activated at TOB Arm accelerates down from TOB

Gluteal muscle groups, scapular stabilizers, and biceps activate

Posting leg supports body weight so gluteus medius must maintain elevation of pelvis on opposite side

Greatest activation of biceps occurs
during acceleration Greatest activation is in gluteal muscles and triceps during ball release


Hips move from relatively parallel orientation to a more perpendicular orientation Shorten the
pitching distance Professional Pitch In Slow Motion There is relatively little muscle activity in this stage because it is a preparatory phase.

The wrist is stabilized in extension.

The amount of trunk lean, elbow flexion, and shoulder hyperextension is relative to the sagittal plane and individualized for each person.

Hip / knee extensors and plantarflexors are activated in back leg providing transfer of weight to pivot foot.

Eccentric contraction of hip and knee extensors in pivot foot as it accepts weight
transfer.

Shoulder flexors move shoulder to 6 o'clock position.

Trunk stability is provided in this phase from the core muscles. The Supraspinatus is the most active muscle in this stage. The Anterior deltoid, Supraspinatus, and Infraspinatus are most active in this stage. The Posterior deltoid, and Teres minor are the most active muscles in this stage. The Subscapularis and Pectoralis major are most active in this stage.
