Type Of Contractions Flashcards
Force of contracting muscle acting on object
Tension
Force exerted on muscle, weight of object
Load
No change in muscle length, exert force in thin filament
Isometric
No change in muscle tone, shortening of muscle fiber has 2 types
Isotonic
Muscle shorten, against gravity
Concentric
Muscle lengthen, works with gravity
Eccentric
Muscle fiber is stretched
Passive tension
The stretched muscle is stimulated
Total tension
Total tension - passive; amount of tension from cross-bridge
Active tension
Length of muscle prior contraction
Initial length
Length of muscle developing maximal isometric active tension
Resting / optimal length
In isotonic contraction, muscle velocity shortening is inversely proportional to _____
Degree of load
When there is no load, muscle contract to ______ velocity
Maximum
As the load increases, velocity ______
Decrease
The muscle is stretched by load prior the contraction
Free-loaded / pre-loaded
