Study Guides
This pupil-friendly study guide includes a unit summary, clear notes, common mistakes, and quick questions with answers.
Unit Summary
This unit will explore basic principles of movement and their effect on sporting performance to include the classification of levers, planes of movement and axis of rotation. This understanding enables pupils to maximise efficiency of movement or generate more power.
Lesson Summary
You will learn to identify and apply each lever system to various sporting actions.
Key Notes
- Sporting examples of a first class lever include the neck when heading the ball in football.
- Sporting examples of a second class lever include plantar flexion at the ankle during a jump shot in basketball.
- Sporting examples of a third class lever include flexion of the elbow in a bicep curl.
Vocabulary To Learn
- first class lever: fulcrum is placed in the middle bewteen the load and effort
- second class lever: load is placed in the middle bewteen the fulcrum and effort
- third class lever: effort is placed in the middle between the load and effort
- mechanical disadvantage: 3rd class levers cannot lift as heavy loads with the same amount of effort as 2nd class levers due to the position of the effort and load from the fulcrum
Common Mistakes To Avoid
- The effort in a lever starts in the belly of the muscle.
3 Quick Questions (With Answers)
1. Explain the lesson in two key points.
Sporting examples of a first class lever include the neck when heading the ball in football. Sporting examples of a second class lever include plantar flexion at the ankle during a jump shot in basketball.
2. What does this key word mean in this lesson? 'first class lever'
fulcrum is placed in the middle bewteen the load and effort.
3. Correct this common mistake.
Mistake: The effort in a lever starts in the belly of the muscle. Correction: The effort from a muscle will start from the muscle insertion. The insertion is the tendon attached to the bone which that muscle moves.
