types of muscle | 1. Skeletal or voluntary= allow us to move and create movement 2.involuntary=perform without conscious control, found in walls of internal organs (excluding heart) 3.cardiac=muscles found in the walls of the heart |
Antagonistic pair | muscles work in pair so movement can occur, when one muscle contracts the opposite must relax |
Agonist/prime mover | the muscle that is doing the work,this muscle creates movement |
antagonist | the antagonist must relax when the agonist is contracting to allow movement to occur |
concentric (isotonic) | -muscle shortens -origin and insertion get closer together |
eccentric (isotonic) | -muscle lengthens because of gravity -origin and insertion get further apart |
isometric | -muscles remain the same length -there is no movement |
slow twitch muscle fibres | Oxygen supply=good type of exercise=all fatigue=long time without tiring contraction speed=slower fibre size=small and weak sport suited for= cycling, marathons |
fast twitch muscle fibres | oxygen supply=poor type of exercise=explosive fatigue=short time before tiring contraction speed=fast fibre size=big and strong sport suited for=100m, triple jump |
