Throwing

Question 1

What are the 5 phases of movement in throwing?

Answer 1

1. Stance
2. Preparatory
3. Movement
4. Follow through
5. Recovery

Question 2

Which phase of throwing movement involves the deceleration of the body after movement?

Answer 2

Follow through

Question 3

Which phase of throwing movement involves the muscles lengthening for force generation?

Answer 3

Preparatory

Question 4

Which phase of throwing movement involves a comfortable and balances position as well as aligning the joints and body parts?

Answer 4

Stance

Question 5

Which phase of throwing movement involves the “action” of throwing?

Answer 5

Movement

Question 6

Which phase of throwing movement involves the regaining of balance and position?

Answer 6

Recovery

Question 7

Which phase of throwing movement involves storing potential energy for the throw?

Answer 7

Preparatory (the muscles lengthening stores the potential energy).

Question 8

Which phase of throwing movement involves the conversion of the potential energy gained in the preparatory phase into kinetic energy?

Answer 8

Movement

Question 9

True or false:

Pitching from the stretch increases the wind-up time.

Answer 9

False

Question 10

What is the cocking phase of throwing?

Answer 10

The time from when the ball leaves the glove to the point of maximal external rotation of the shoulder.

Question 11

What are the two things the preparatory category is divided into?

Answer 11

Wind up and cocking

Question 12

What is the wind up?

Answer 12

The initiation of the pitching motion to the ball leaving the glove–the thrower is positioning the body so all the segments can coordinate themselves for throwing. This begins to build up energy from the hips, thighs, and core.

Question 13

What gives time to transfer energy from the lower body and core to the upper body to increase the force of throwing?

Answer 13

Cocking.

Question 14

What is the reason for the cocking phase of throwing?

Answer 14

To increase the distance force that is applied to the ball.

Question 15

What movements occur during the cocking portion of the preparatory phase?

Answer 15

The stride leg is lifted, moves forward, & then plants.

The shoulder reaches the point of maximal external rotation as well.

Question 16

What is the movement phase also known as in throwing?

Answer 16

The acceleration phase

Question 17

What happens during the acceleration (movement) phase of throwing?

Answer 17

From when the hand begins to move forward to the point where the ball is released.

Question 18

What happens to the anterior structures during the acceleration phase?

Answer 18

They were wound up like a spring and then released to accelerate the ball.

Question 19

What is the most common phase of throwing to produce pain?

Answer 19

The acceleration (movement) phase.

Question 20

How fast is the arm moving during the acceleration phase of throwing?

Answer 20

However fast the speed of the ball is–for example, if you throw a 98mph fastball, then your arm was moving at 98 mph during the acceleration phase.

Question 21

What is the average speed of internal rotation during the acceleration phase of throwing?

Answer 21

6000+ degrees/second.

Question 22

What two things is the follow through phase of throwing divided into?

Answer 22

Deceleration and follow through.
