Types of Muscle Contraction Flashcards
1
Q
Isometric contraction
A
- tension is developed within muscle but joint angles remain constant
- aka static contractions
2
Q
Isotonic contractions
A
- involve muscle developing tension to either cause or control joint movement
- can be either concentric or eccentric
- aka dynamic contractions
3
Q
Passive contractions
A
Movement might occur at any given joint without any muscle contraction whatsoever
4
Q
Concentric contraction
A
- involve muscle developing tension as it shortens
- causes movement against gravity
- described as being a positive contraction
5
Q
Eccentric contraction
A
- involve the muscle lengthening under tension
- force developed by the muscle is greater than that of the resistance
- causes body part to move against gravity
- results in joint angle changing
- described a negative contraction
6
Q
Isokinetics
A
a type of dynamic exercise using concentric and/or eccentric muscle contraction
7
Q
Conditions for isokinetic exercises
A
- the speedo f the movement is constant
- muscular contraction occurs throughout movement
- NOT another type of contraction
