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
