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