Muscular Definitions Flashcards
1
Q
What is isometric?
A
- contraction with no movement
- i.e., holding the weight at the top
2
Q
What is isotonic?
A
- contraction with movement
- i.e., bicep curl
3
Q
What is concentric ?
A
- movement that shortens the muscle
- i.e., upward motion of a bicep curl
4
Q
What is eccentric?
A
- movement that extends the muscle
- i.e., lowering phase of a bicep curl
5
Q
What is agonist?
A
- the primary mover
- the primary muscle creating a concentric movement
6
Q
What is antagonist?
A
- opposing or reciprocal muscle to the agonist
- inactive while the agonist is contracting
7
Q
What are fixators?
A
- steadies the proximal part of the limb throughout an isometric contraction while movement happens distally
8
Q
What are synergists ?
A
- complements action of the prime mover
