Anatagonistic muscle
Types of muscles contractions and antagonistic pairs
Question | Answer |
---|---|
What is an Agonist | - these are the muscles that cause the movement |
What is an Antagonist | these are the muscles that relax (eccentrically contract) to allow the movement to |
What is a Synergist | muscles that work along side the agonists helping with control and direction of the movement |
What is a Fixator- | these stabilise the origin of the muscle |
What is an Isometric contraction | increase in muscle tension the muscle does not change in length |
What is a Concentric contraction | increase in muscle tension as it shortens |
What is an Eccentric contraction | increase in muscle tension as it lengthens |
Example of an eccentric muscle contraction? | Controlling , slowing, downward movement squat downward phase/press up downward phase |
Example of concentric muscle contraction ? | A movement that accelerates upward phase of bicep curl/ running |
Name a sporting action that uses a concentric muscle contraction? | Forehand in tennis / jumping up / bicep curl upward phase / press up upward phase |
Name a sporting action that uses an eccentric muscle contraction? | Downward phase of squat / running downhill or stairs / downward phase of a jump / landing after a jump / downward phase of a bicep / press up down ward phase |
Name a sporting action that uses a isometric muscle contraction? | Crouch position of skier / held handstand / plank / weightlifter holding a weight above head |
