- 1Force summationThe process by which an athlete calls on different parts of the body to maximise force production
- 2Types of force summationSimultaneous and sequential
- 3What is simultaneous and sequential force summationSimultaneous - force harnessed at the same time
Sequential - force produced by a times sequence - 4How to maximise sequential force summationUse as many segments of the body as possible
In the correct sequence and using large muscles first and the smaller
Timing
Greatest range of motio - 5Newton 1st lawAn object will remain at rest or in uniform motion in a straight line unless acts upon by an external force
- 62nd lawAll existing forces are not balanced
Acceleration is dependant on net force and mass
Larger the mass the lower the acceleration - 73rd lawFor every action there is an equal and opposite reaction
- 8MomentumThe quantity of motion of a moving body measured as a product of its mass and velocity
- 9InertiaA tendency to do nothing or to remain unchanged
- 10DisplacementThe action of moving something from it’s starting position
- 11SpeedThe rate at which someone orsomething moves or operated or is able to move or operate
- 12VelocityThe speed of something ina given direction
- 13Accelerationa vehicles capacity to gain speed
Change in velocity / time - 14ImpulseIntegral of a force, over the time interval for which it acts
- 15StabilityThe state of being stable
- 16Centre of massA point representing the mean position of the matter in a body or system
- 17Projectile motionForm of motion experience by an object thrown near the earths surface under the action of gravity
- 18Resistive forcesForce whose direction is opposite to the velocity of the body or of the sum of the other forces and refer to friction
- 19Mechanical advantageThe ration of the force produced by a machine to the force applied
- 20LeversBones ligaments and muscles
- 21PowerMove or travel with great speed or force
- 22FlexionDecreasing angle between two bones
- 23AbductionMoving a body pry away from the midline
- 24PronationRotating a body
Part so that the palm is posterior - 25ElevationRaising a body part
- 26RetractionPulling a body part backwards
- 27Plantar flexionBending a foot away from the shin
- 28InversionRotation of the sole of the foot inwards
- 29EversionMovement of the bottom of the foot away from the midline of the body
- 30Hyper flexionThe abnormal or excessive flexion of a joint beyond its
Normal range of motion - 31Hyper extensionThe abnormal or excessive extension of a joint beyond its normal range of motion
- 32MidlineAn imaginary line that runs vertically down the middle of the body through the middle of the body
- 33Velocity calcDisplacement / time
- 34Change in velocity calcCurrent speed - initial speed
- 35Base of supportContact with the floor and space in between
- 36Centre of gravityLocated at belly button. To lower bring centre of gravity closer to the base of support
- 37Height of releaseHeight st which an object is released
- 38Speed of releaseSpeed at which an object is travelling
- 39Angle of releaseAngle at which an object is released
