What is a concentric contraction?
concentric contraction is atype of muscle contraction which the muscle shortens while genrating aforce The muscle shortens to produce movement. A muscle contraction in which shortening occurs.
what's an isometric contraction?
An isometric contraction is when the muscle does not shorten and no movement results.

during isometric contraction, the energy used appears as movement
Isometric contraction leads to load movement.?
no
What is the type of contraction in which the muscle fibers produce increased tension but does not shorten?
An isometric contraction builds tension but there is no joint movement.
What type of muscle is capable of rapid contraction and causes skeletal movement?
Skeletal or voluntary muscle is capable of rapid contraction and is responsible for skeletal movement.
Does muscle contraction always promote movement?
No , a muscle may be stretched with out movement .
In which direction does friction act compared o the direction of movement?
