Isometric Exercise — Muscular contraction where muscle maintains a constant length and joints do not move.
The tests are performed individually and involve a static, timed, isometric contraction of the core muscles stabilizing the spine until the individual exhibits fatigue.
Isometric contractions occur when the muscle contracts but there is no movement.
By sustaining extended isometric contractions, we can build up muscle endurance and focus on developing proper motor control and stability patterns through the hips, core, and shoulders.

The purpose of the exercise is to stimulate your muscles through isometric muscular contraction, which is a fancy way to say «flexing your muscles in a set position for a set amount of time.»
Isometric exercises — exercises that involve muscle contractions with no movement, such as clasping your hands and pressing your arms together — can be a great way to start resistance training.
However, it is unclear whether the soleus muscle activity is greater during flexed positions when performing isometric contractions.
Because of the isometric contraction of planks, they also make your ab muscles work more efficiently without placing the tension on your back.
You can recruit almost all muscle fibers / motor units in a maximal isometric contraction.
The isometric contractions and balance positions engage all of the muscles and can provide an effective overload, according to McCall.

So in this article I'll explain what isometrics are, the different types of isometric contractions you can do, and how to use them to build both maximum strength and muscle size too.
Most PNF stretching techniques employ isometric agonist contraction - relaxation where the stretched muscles are contracted isometrically and then relaxed: After assuming initial passive stretch, the muscle being stretched is isometrically contracted for 7 - 15 seconds, then the muscle is relaxed for 2 - 3 seconds, and then immediately stretched again (even further than the initial passive stretch) for 10 - 15 seconds.
There are PNF techniques that use isometric contraction of antagonist muscles where the antagonists of the stretched muscles are contracted.
Small study said it did nothing but decrease muscle endurance (I'm guessing because muscular endurance is related to estrogen, which was been indicated in other studies on the difference between males and females preforming isometric contractions).
The reason why is because a muscle will only get stronger in the range of movement you put it in (or to simplify it) the best way to get the strength your hip muscles and hamstrings need to do the splits is you've guessed it, isometric contractions in the splits position.
You should find that after every isometric contraction your muscles will relax so much that you are able to push the rear leg back whilst still maintaining a 90 degree angle at the front leg knee.

Similarly, training using a partial range of motion (which is similar to using isometrics at short muscle lengths) increases strength around the joint angle corresponding to the peak contraction.
As for residual force enhancement, several experiments have found that single muscle fibers subjected to maximal (tetanized) contractions produce lower tension after a being shortened to a standard length, compared to a comparable isometric contraction at the same standard length, without the preceding shortening phase.
Thus, these studies suggest that the length of the muscle during strength training may not be an important factor for altering muscle fascicle length, at least when using isometric contractions.
