Cards in this deck (9)
- 1types of muscle1. 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 - 2Antagonistic pairmuscles work in pair so movement can occur, when one muscle contracts the opposite must relax
- 3Agonist/prime moverthe muscle that is doing the work,this muscle creates movement
- 4antagonistthe antagonist must relax when the agonist is contracting to allow movement to occur
- 5concentric (isotonic)-muscle shortens
-origin and insertion get closer together - 6eccentric (isotonic)-muscle lengthens because of gravity
-origin and insertion get further apart - 7isometric-muscles remain the same length
-there is no movement - 8slow twitch muscle fibresOxygen supply=good
type of exercise=all
fatigue=long time without tiring
contraction speed=slower
fibre size=small and weak
sport suited for= cycling, marathons - 9fast twitch muscle fibresoxygen supply=poor
type of exercise=explosive
