Describe how the impulse crosses the synapse
- vessicles release Ach into the synapse - if there is enough impulses, Ach will reach threshold - the Ach will attach to receptor sites on the following dendrite which increases the membrane permeability
100
What happens to a learning curve?
Increases get smaller, plateaus get longer
100
PRP - in order for the 2nd response to occur, what happens?
Attention must be required but it taken up with the first response
100
Describe conservation of angular momentum:
- the further the mass is from the axis, the greater the angular momentum - increase by moving mass to the perimeter (making racket longer)
100
GAS?
General adaptation syndrome - the body responds to any stressor the same way
200
What is the importance of cholinesterase? (Achase)
When Ach is released in the synapse, Achase is released to destory the leftover Ach so that neurons will not randomnly fire
200
What are the 3 stages of learning?
Cognitive, associative, autonomous
200
What are the two types of motion?
Linear (straight line) and rotational (around an axis)
200
Newton's three laws?
Inertia, Acceleration, Action/Reaction
200
The human heart is made up of how many chambers?
4
300
What is a fine motor skill?
Require ability to control small muscle groups
300
What is a schema?
Set of rules that provides the basis for a decision
300
What are the 7 principles of biomechanics?
stability, maximum effort, summation of forces, impulse, newton's third law, angular motion, conservation of angular momentum
300
6 training principles:
Specificity, progression, overload, reversibility, diminishing returns, individual differences
300
The last chamber the blood flows through on its path through the heart is the
left ventricle
400
What is a continuous skill?
Arbitrary end points, the performer determines when the skill beings rather than the skill itself
400
What are two elements of Adam's closed loop theory?
Perceptual trace and memory trace
400
Describe the principle of impulse:
forces should be applied as long as possible (long strides skating)
400
What is reversibility?
muscles begin to lose the benefits the training brought in the first place
400
What is the HR of a marathoner?
40
500
What is an open environment?
Skill involving an unstable environment and changing skill
500
What is Hick's law?
Every time the # of stimulus/response choices double, RT increases 150 ms
500
Describe angular motion
-hit away from COM - create spin - want torque
500
Diminishing returns:
a person's training gains will reflect that person's prior level of training
500
What is the correct sequence of the nervous stimulation of the heart?
SA node, AV node, purkinje fibers
