Types of contractions Flashcards
1
Q
What do muscle not have to do to generate force
A
don’t need shorten
2
Q
What are the 2 types of muscle contraction?
A
Isotonic (same tension) contraction
Isometric (same measurement) contraction
3
Q
What does isotonic contractions do?
A
Involves shortening of muscle
Associated with movement such as lifting a weight
As muscle shortens, tension remains the same
4
Q
What does isometric contraction do?
A
Involves force generation without shortening
Force is used to resist overstretching and oppose gravity
E.g holding a weight in one position
5
Q
What type of contract are most movements
A
combination of both types of contraction
6
Q
What is an example of a movement with both contractions
A
Picking up a weight is isotonic
keeping the weight in the same position is isometric
