1.Stability: A person is more or less stable depending on the area of
their support- ing base
2.Acceleration: The rate of change in velocity over a certain period of tim
3.Torque: The force that causes something to rotate
4.Force: The push or pull exerted on an object
5.Mass: The quantity of matter in an object
6.Center of Gravity (COG): AKA Center of
Mass More Stability= lower center of
gravity
For Max stability= COG is perpendicular to the ground and the center of
the base
Movement requires you to change your center of gravity
7.Friction: The force created by an object's contact with the ground.
Depends on
,1) Weight of the Object
2) Surface of the ground
8.Tonic Neck Response: Movement in relation to the neck and limbs
9.Centripetal Force: The force exerted on an object moving in a circle
10.Inertia: Any object's resistance to a change in velocity
11.Weight: Mass x Gravitational Constant
Will vary depending on the gravitational force
12.Momentum: The tendency of an object in motion to stay
moving Mo= velocity x mass
Objects with the same speed will have different momentum if the masse
are different
13.velocity: The measure of speed and direction of an object
Velocity= distance/time or Final Distance- Initial Distance/Time
14.After- Contraction Phenomenon: The increase in the force of
, movement that seems to happen when the neuromuscular systems
become excited
eg. Pressing against a wall for a minute
15.Flexibility: The range of motion around particular joints
16.Exercise and Muscles: greater muscle endurance = greater aerobic
capacity & aerobic metabolism
Muscles are best exercised when overloaded
17.Water and Exercise: People can lose up to a quart of water through
sweat alone
The heart has difficulty providing oxygen to the heart when dehydrated
18.Strategies of Exercise: Building strength and Building endurance:
Building strength= low reps heavy weight, gradually increasing weight
Building endurance= large reps, low weight
19.Ballistic Stretching: When one jerks or bounces muscles around when
stretch- ing
