Levers
What is the main type of lever we use in sports?
Third Class Levers
What are the three stages of learning?
Cognitive, Associative, Autonomous
What are the three main types of constraints?
Individual, Task, Environmental
What is the formula to find force?
Force = Mass x Acceleration
What is massed practice?
Uninterrupted practice of a specific skill during a practice session
Draw what a third class lever looks like
Joint -----force-----load
What stage is commonly the longest?
Associative
What type of constraint is changing the equipment used?
Task
What are two key things we need for good force summation?
◦Timing of movement
◦ Correct Sequence
◦Large body parts to small
◦As many body parts as possible
◦Greatest range of motion/Optimal range of motion
◦What is distributed practice?
Short sessions with frequent rest periods
What kind of lever is used in a serve in volleyball?
Third Class Lever
Which type of feedback would you not associate with a cognitive learner?
1. Terminal
2. Negative
3. Positive
4. Extrinsic
Negative
What are two examples of an environmental constraint?
◦Crowd, temperatures, lighting, playing conditions (wet/heat)
Which one has the greatest force?
Cricket ball = Mass - 1.22 x Acceleration - 25
Rock = Mass 1.23 x Acceleration - 35
Rock
What is part practice?
Parts, or components of the skill are practised
What is an example of a Second Class Lever?
Wheel barrow, stapler, nut cracker, nail clippers
Which stage will focus more on tactics and strategies?
Autonomous
If an athlete is not 4'9 and wants to play basketball, what is this constraint and which of the three does it fit into?
Individual and height
Which person would have greater force? Why?
Golf player puttering
Golf player driving
Golf player driving, uses more muscles, biggest to smallest, greatest range of motion
◦What is problem-solving practice?
◦More related to what happens in a game
◦Uses tactics, strategies, problem solving, ‘game sense’
◦Skill is embedded in the game
What is an example of a First Class lever?
Seesaw, scissors
Which type of feedback is more appropriate in the Autonomous stage?
Intrinsic
If I make successful drop shots two points, what type of constraint is that?
Task
Which serve would produce more force, a jump serve or a standing overhead serve
What is an example of problem-solving practice?
3 v 3 basketball
