What are the classifications of skills?

Answer 1

Gross, Fine, Closed, Open skills.

What are the characteristics of gross and fine motor skills?

Answer 2

gross motor skills are a large group of muscles and fine are a smaller group of muscles.

Answer 3

low inter-trial variability.

Question 4

What are the 3 stages of learning?

Answer 4

Cognitive, Associative, Autonomous.

Question 5

What are two characteristics of each S.O.L?

Answer 5

Cognitive - complete beginner and has errors in performance.
Associative - ability to detect errors and focuses on skill refinement.
Autonomous - almost perfect and has a high skill level.

Question 6

What skill has no distinct beginning or end?

Answer 6

Continuous.

Question 7

What skill has a distinct beginning and end?

Answer 7

Discrete.

Question 8

What skill has several discrete movements?

Answer 8

Serial.

Question 9

What is Massed practice and what is an advantage?

Answer 9

Massed practice has little rest and covers a lot of different skills. An advantage is that performers can complete a variety of skills.

Question 10

What is Blocked practice and what is an advantage?

Answer 10

Blocked practice involves the repetition of the same skill. An advantage is that it develops motor skill development quicker for the performer.

Question 11

What is distributed practice?

Answer 11

Distributed practice is short sessions but they are more frequent.

Question 12

What is random practice?

Answer 12

Random practice involves a variety of different skills in a training session.

Question 13

What is QMA?

Answer 13

preparation, observation evaluation, and error correction.

Question 14

What are some socio-cultural factors?

Answer 14

Family, SES, gender, peers, local community, beliefs/norms.

Question 15

What is a task-constraint?

Answer 15

A task constraint any change of rules within a game.
This can include size of field and different equipment used.

Question 16

What is a environmental constraint?

Answer 16

An environmental constraint is anything external to the athlete. This includes, noise level, weather, terrain, access to facilities.

Question 17

What are some individual constraints?

Answer 17

Body weight, fitness, genetics, mental skills.

Question 18

What is the relationship between motor skill development, participation, and performance?

Answer 18

Motor skills can be an enabler or barrier to participation. People are more likely to participate if they have the skills required which enhances their performance.

Question 19

Advantages of CONSTRAINTS BASED coaching?

Answer 19

learner orientated, explicit instruction, discovery based.

Question 20

Disadvantages of CONSTRAINTS BASED coaching?

Answer 20

Errors in performance, not suitable to all, time consuming.

Question 21

Advantages of DIRECT BASED coaching?

Answer 21

explicit learning, focus on skills, builds confidence.

Question 22

Disadvantages of DIRECT BASED coaching?

Answer 22

Coach orientated, autocratic, commanding.

Question 23

What is inertia?

Answer 23

Inertia is the reluctance of an object or body to change.

Question 24

What is moment of inertia and it’s formula?

Answer 24

Moment of inertia is the resistance of an object to change it’s angular motion. Mass x Radius 2.

Question 25

What does greater mass allow and what does less mass allow?

Answer 25

Greater mass allows for a greater inertia and a lighter mass allows for less inertia.

Question 26

What is force and it’s formula?

Answer 26

Force must be unbalanced to overcome inertia. F = M x A.

Question 27

High moment of inertia means you have spread or closed body parts?

Answer 27

spread.

Question 28

What is the formula for momentum?

Answer 28

Momentum = Mass x Velocity.

Question 29

What is impulse and it’s formula?

Answer 29

Impulse is the change in momentum of an object. I = F x T.

Question 30

Aim of Force Summation/Summation of momentum?

Answer 30

The aim is to generate momentum and force in a sequential manner in the body.

Question 31

What is angular momentum?

Answer 31

Angular momentum is conserved when the body is in flight.

Question 32

Greater momentum is harder to…

Answer 32

Stop.

Question 33

If moment of inertia DECREASES the ANGULAR VELOCITY will increase to conserve what?

Answer 33

Angular momentum.

Question 34

What is Newton’s First Law?

Answer 34

Inertia. Newton’s first law states that an object will remain at rest unless an external force is acted upon it.

Question 35

What is Newton’s Second Law?

Answer 35

Acceleration. Newton’s second law states that the acceleration of an object is directly proportional to the force and inversely proportional to it’s mass.

Question 36

What is Newton’s third law?

Answer 36

Equal and opposite action-reaction. Newton’s third law states for every action there is an equal and opposite action-reaction.

Question 37

What is Linear motion?

Answer 37

Motion that occurs in a straight line.

Question 38

What is speed?

Answer 38

How quickly a body moves over a certain distance.

Question 39

What are 2 external factors that affect projectile motion?

Answer 39

Air resistance and gravity.

Question 40

3 influences of projectile motion are:

Answer 40

Height of release, angle of release, speed of release.

Question 41

What is velocity?

Answer 41

Displacement/Time.

Question 42

What is torque?

Answer 42

The tendency of an object to rotate.

Question 43

Distance vs Displacement.

Answer 43

Distance is the total distance a body have covered from start to finish.
Displacement is the change of position from the start to the finish.

Question 44

What is angular motion?

Answer 44

The movement of a body around a central point.
