- 1. Strength<br />Thursday 5th May<br />9am – 11am <br />
- 2. Today’s lesson<br />Aim:<br />To know and understand strength<br />Objectives<br />To list and describe the different types of strength<br />To discuss and complete ways to test and train for strength<br />To explain the factors that affect strength and training<br />
- 3. What are the different types of strength?<br />M---m-l St-e---h<br />Maximal strength: maximum force produced in a single muscular contraction<br />E --lo---e Strength<br />Explosive strength: or power, a combination of speed and strength<br />Strength E--------<br />Strength Endurance: the ability to sustain a number of muscular contractions over a period of time<br />
- 4. Two more dimensions<br />There are a further two dimensions to categorise strength<br />Static strength<br />Dynamic strength <br />What might these two types of strength describe?<br />Static … force exerted against a resistance but no movement<br />Dynamic …force exerted causing change in body position<br />Can you think of an example of each??<br />
- 5. Examples of strength<br />Static … handstand<br />Dynamic<br /> … backflip<br />
- 6. Get scribbling on your whiteboard<br />Question: What factors might affect strength?<br />
- 7. Factors affecting strength<br />Your genetic muscle fibre type dictates your strength<br />potential and the percentage you have within your muscles.<br />Why? Discuss<br />Also the cross-sectional area of the muscle determines its<br />strength output.<br />What is it called when the x-sectional area increases in size?<br />
- 8. What else makes us strong?<br />Age optimum age for strength is in our …<br />… twenties <br />Gender there is no difference in pure muscle tissue between females and males<br />So why are males stronger? <br />higher testosterone levels<br />
- 9. Energy systems<br />The predominant energy system being used will depend on the type of strength being utilised<br />TASK (5 minutes)<br />Can you think of examples from sport?<br />Discuss this point together<br />
- 10. Energy systems<br />
- 11. Match the Adaptations<br />
- 12. Resistance training increases total number of motor units recruited and improved synchronisation.<br />Neural Adaptations<br />
- 13. Get your whiteboards ready<br />Question: What have you remembered from today!<br />
- 14. The body’s ability to apply a force<br />Whatis the above sentence describing?<br />… the maximum force thatcan be developed in a muscle or group of muscles during a single maximal contraction<br />
- 15. Maximum strength<br />Which example would you choose for maximum strength?<br /> A B C <br /> A B C<br />
- 16. Right answer is …<br />B<br />The judo throw requires overcome of a very large force<br />
- 17. Elastic strength<br />Which example would you choose for elastic strength?<br /> A B C <br /> A B C<br />
- 18. Right answer is …<br />A<br />The gymnast needs explosive strength in a sequence<br />
- 19. Strength endurance<br />Which example would you choose for strength endurance?<br /> A B C <br /> A B C<br />
- 20. Right answer is …<br />A<br />Rowing requires repeated contractions without fatigue<br />
- 21. Task<br />You are now going to research one type of strength<br />How to test for it<br />How to train for it<br />Gary – maximal strength<br />Charlotte – explosive strength<br />Chris – strength endurance<br />Testing and Training for different types of strength<br />
- 22. Testing and Training for different types of strength<br />
- 23. Plenary – musical mastermind<br />The winner is the contestant with the most points<br />You will get 2 minutes on strength questions<br />Everyone else will take it in turns to ask you questions<br />If you answer incorrectly the answer is read out losing you valuable time<br />You may pass three times<br />
- 24. musical mastermind<br />
