- 1. Muscles and Movement. Aims: To know the different muscle types in our body. To understand the different types of muscular contractions. To know the roles of the different muscles during a sporting action.
- 2. Recap from previous lesson. Add this info to your spider diagram!!! Elbow Femur, Tibia, Fibula, Patella Shoulder Carpals Wrist Articulating bones Joint type Location
- 3. What are the 3 Different types of muscle found within our body? Skeletal – Voluntary Cardiac – Involuntary Smooth – Involuntary This topic focuses upon voluntary skeletal muscle.
- 4. Functions of skeletal muscle. Muscles can only pull (contract), they have specific roles as members of a group of muscles to produce movement. Three Roles: Agonist (Prime Mover) muscle Antagonist muscle (opposite action) Fixator muscle (contracts isometrically)
- 5. For the bicep curl exercise, which muscles form the; agonist, antagonist and fixator ? (flexion of the elbow) Agonist muscle : Directly responsible for the movement at a joint. E.g. Biceps. Antagonist : Opposing action to that of the agonist. E.g. Triceps. Fixator: Allows the agonist to work effectively by stabilising the origin of the agonist. E.g. deltoid.
- 6. Task. With a partner; act out a number of different sporting actions. E.g. kicking a ball, chest pass etc. Draw a diagram of this action. Identify the : Agonist, Antagonist and Fixator muscles involved with this movement.
- 7. The two main types of muscular contraction Isotonic Isometric No movement. Movement occurs. Eccentric = lengthening. Concentric = shortening.
- 8. The role of muscle contractions. Isotonic – concentric contraction occurs in agonist muscles. Isotonic – eccentric contraction occurs in antagonist muscles. Isometric contraction occurs in fixator muscles which stabilise joints aiding muscle movement.
- 9. Homework Learn the different muscles within the body. I will be testing you next lesson. You need to know all the muscles in the Quadriceps and Hamstrings!!
