The training muscular endurance ( isometric contraction ), is getting more and more important. A lot of the benefits that are achieved and you get this kind of training. In the following, we will cover this topic and give a couple of very interesting and useful information.
Can you doing the long-run, but when you need to doing endurance squat for 20 seconds, that make the problem arises. This shows that isometrically contractions are not that easy. Today, isometric exercises regaining popularity in the fitness world.
First, to clarify what is isometric exercise and contraction? Isometrically exercises are those exercises that are performed without changing the length of the muscle. These exercises are performed when the body is in a static position and requires muscle tension without any real movement. There are 3 main modes of muscle (muscle contraction), in relation to any action of muscle fibers – Concentric contraction, which involves reducing or shortening of the muscle fibers; Eccentric contractions, which includes the extension of the muscle fibers; and Isometric contraction where muscle fibers taut and without any changes in the length. The exercises of yoga and Pilates classes are mostly isometric nature.
Exercises of isometric contraction is play important role in the thickening of the muscle fibers, and thus strengthen a muscle. It is very important in the body and their muscles, which suffer high loads, such as the spine and spinal cord, knees and neck. The fact that the spinal cord and the muscles surrounding it, can withstand compression from 200 to 300 kilograms, and the rotation of only 9 kilograms, it says that if the muscles of the spinal column weakens and just taking out the crates of beer from the trunk and rotation of the spine, can lead to serious damage to the spinal column. Research shows that 6 minutes of exercise isometric contractions can even replace 30 to 35 minutes classic forms of training in the gym. Power Plate exercise, Dead lifts, Squats and Lounge are very burdensome exercise for knee, therefore exercises to strengthen leg muscles (thigh and hamstring) isometrically contractions are very much needed and necessary. This type of training also stabilizes the pressure (arterial and venous), improves heart function and stabilize the heart rate.
The most common exercises that are performed are: PLANK ( on hands or elbows), SIDE PLANK, isometrically push ups ( endurance in push ups ), endurance of SQUAT ON THE WALL OR ON PILATES BALL, endurance IN CRUNCH position for ABS, isometrically endurance ON THE GROUND FOR STRENGTHENING back muscles …
Certainly that was required to continually change the way of training, in order to have more motivation and more effects on the body, but this type of training should be frequently present with you, just for these reasons that we mentioned above. Later, you can devote weights to form muscles or increase muscle mass, but without a strong spine and core muscles will all be in vain, and may cause serious injuries.
