1. Transferable Movement Skills and Principles
August 30th, 2010
Lesson 5

2. Transferable Movement Skills and Principles- Sending
Preparation
Wide base of support (feet shoulder-width, knees bent)
Shoulders square to target
Eyes on target
Execution
Apply force in direction of target
Release object at point where it will hit target
Follow-through
Follow-through in direction of target
Maintain balance ready for next movement

3. Transferable Movement Skills and Principles- Receiving
Preparation
Strong base of support
Provide target for the sender
Keep your body between object and defender
Focus eyes on path of object until received
Execution
Reach out to meet object
Receive object with appropriate instrument (hands, feet, glove, etc.)
Follow-through
Absorb force of the object
Bring object closer to body
Re-establish strong base of support
position object for next movement (triple threat: pass/shoot/carry)

4. Transferable Movement Skills and Principles- Carrying
Preparation
Strong base of support (athletic stance)
Head up looking for offensive advantage
Execution
Keep object under control (close to body)
Protect object with the body (keep your body between object and the defender
Move object toward goal trying to create an offensive opportunity

5. Some Biomechanical Principles -Building Blocks for Skills
1. The lower the centre of mass and the larger the base of support the greater the stability.
- In some sports, athletes become totally unstable when they lose contact with the ground for short periods of time.

6. Some Biomechanical Principles -Building Blocks for Skills
2. The production of maximum force requires the use of all possible joint movements.
-With more joints coming into play in a given skill, the more muscles there will be to contract – leading to greater force being exerted.

7. Some Biomechanical Principles -Building Blocks for Skills
3. The production of maximum velocity requires the sequential use of joints in order – from largest to smallest.
-Maximum velocity is generated when the movement starts from the legs and torso and finishes with the smaller joints of the hands or feet.

8. Some Biomechanical Principles -Building Blocks for Skills
4. The greater the applied impulse, the greater the increase in velocity.
-Increase in range of motion of a joint will result in greater application of force. This principle often occurs in reverse: “soft hands” to absorb the impulse of an incoming object.

9. Some Biomechanical Principles -Building Blocks for Skills
5. Movement usually occurs in the direction opposite that of the applied force. (Every action as an equal and opposite reaction – Newton’s Third Law)
-Occurs whenever an athlete pushes against a playing surface or a piece of equipment.

10. Some Biomechanical Principles -Building Blocks for Skills
6. Angular motion (spin) is produced by the application of a force acting at some distance from an axis (torque).
-In many sports, being able to put spin on an object is a key component of strategy.

11. Question
Think about how a baseball is thrown. How do the 6 biomechanical apply to the throw? Break down the effect that each principle has on the throw.
This may require you to get out of your chair.
This will be handed in.
