Isometric: Iso means same and metric means length. A con traction is said to be isometric when tension in the muscle is developed but there is no change in the length of the muscle. This is also called static contraction because the **** angle does not change. For example, holding a weight at arm' length, pushing against the wall.
So isometric exercises are those in which no movement takes place while force is exerted against an immovable object. It develops tension only at ***** concerned.
There is neither shortening nor lengthening which results in no visible muscular effort. Such types of contractions are more useful for weightlifters, gymnasts, wrestlers, etc
For example:
(a) Holding half push-ups
(b) Flexed arm hang
(c) Pushing against the wall
