CH 5: types of muscle contractions Flashcards
What muscle contraction occurs when tension is produced and shortening of muscle takes place?
Concentric
What muscle contraction is referred to as a lengthening contraction?
Eccentric
What muscle contraction occurs when tension is produced and lengthening of the muscle occurs?
Eccentric
What type of exercise involves loading a muscle, causing a physical lengthening of the muscle as it attempts to control the load when lowering the weight?
Eccentric
What muscle contraction occurs when tension is produced but no joint movement or action occurs?
Isometric
What muscle contraction involves a muscle contraction against force with no significant movement occurring?
Isometric
What muscle contraction is used when joint movement is restricted or impossible?
Isometric
What muscle contraction is a muscle-setting exercise?
Isometric
The word “Set” describes what type of muscle contraction?
Isometric
Isometric exercises are used for?
- Decrease pain
- Facilitate muscle contraction
- Increase circulation
- Retard muscle atrophy
What describes the action of variable velocities of movement with a constant load?
Isotonic
What are example of isotonic resistance equipment?
Free weights (barbells, dumbbells, ankle weights)
What contraction occurs when the resistance, force, load or tension remain constant, whereas the tension created changes as the joint angle changes?
Isotonic
What type of contraction occurs when the speed or velocity of movement is held constant regardless of the magnitude of force applied to the resistance?
Isokinetic
What type of exercise is called accommodating resistance?
Isokinetic
