skills
What is a fundamental movement skill?
Basic learned movement patterns and form the foundation for the development of sport specific skills
When would a coach use part practice?
cognitive learner
complex skill
new skill
What is the inverted U hypothesis?
increased athlete arousal has a positive effect on performance but only up to a certain point/level
What are the 2 types of motion?
linear and angular
What is the definition of Newton's second law?
Law of acceleration - Force = mass x acceleration
what are 3 key aspects of an open skill?
unstable environment
pacing is external
high inter trial variability
What is an advantage of massed practice?
Which athlete does it suit?
maximises practice time, non fatiguing skills
elite or highly motivated performer
Define:
Knowledge of performance feedback
Knowledge of results feedback
Bonus point which learner benefits from which?
Performance - information of the process of performing skill
results - information about outcome of performance
Cognitive - both (results for cognitive could relative to how performance felt when hitting ball correctly or scoring)
Assoc, autonomous - performance
List any 2 biomechanics formulas
momentum = mass x velocity
speed = distance/time
velocity = displacement/time
impulse = force x time
What s the definition of Newton's 1st law?
Law of inertia - an object will remain at rest or in uniform motion unless acted on by an unbalanced force
What are the 3 type of movement skills?
discrete, serial, continuous
What is a disadvantage of direct approach to coaching?
doesn't develop decision making skills
the learner makes more errors in a competitive environment
boring, repetitive
poor transfer of learning
What are the 4 psychological skills?
What is one strategy to increase one of them?
Confidence, motivation, optimal levels of arousal, concentration
Apply conservation of momentum to cricket and give an example where you could see it?
Ball hitting stumps
Ramp shot
bat hitting ball
What is the definition of Newton's third law? Give an example of this from cricket
Law of action and reaction - for every action there is an equal and opposite reaction
eg. pushing off to run, bat hitting the ball, jumping to make a catch or dive sideways
In the direct approach to coaching (linear learning) how are skills practiced?
skills learned in isolation
learning aspires to textbook technique
skill and drill
What are two disadvantages of non-linear (constraints) based coaching?
cognitive can become overwhelmed with rules/tactics
skills may lack refinement
skills may take longer to develop, harder for coach to give feedback
What is the definition and formula for angular momentum?
measure of how much rotation a body has around an axis
angular momentum = moment of inertia x angular velocity
Give two aspects of force summation
Large body parts to small
Sequenced correctly
Stabilisation of body
Timing
Apply Newton's 2nd law to a tennis ball vs a cricket ball that has been bowled.
Force = mass x acceleration
Cricket ball has more mass therefore will take more force to throw but will also generate more force than a tennis ball and therefore be harder to hit
What are 3 types of task constraints? Pick one and explain how it assists a cognitive learner
goal
rules
equipment
facilities
You have a cognitive learner list:
Type, distribution and variability of practice you would use.
Justify your answer
Part and whole
Distributed
Blocked
Projectile motion - for maximum horizontal distance, when is the best angle 45 degrees, <45, >45
45 = height of release = landing height
<45 = height of release is greater than landing height
>45 height of release is lower than landing height
When answering biomechanic questions what does the acronym DEEP stand for?
Define
Equation
Explanation
Performance link
Give an example of each of Newton's laws in the game of basketball
1. player on the post, player boxing out, the ball not moving unless passed or shot, player taking a charge
2. player with less mass chasing a larger mass player
3. Jumping, dribbling, pushing off to run,
