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.
Neck pain is a common occurrence these days. Long sitting on the computer, a desk, behind the wheel is the common causes of this problem. In this article we will explain this phenomen and try to help in the elimination of the same.
Pain in the cervical spine may spread to one or both shoulders, shoulder blades or the front of the chest, and neck stiffness were monitored and limited motion of the cervical spine. If the pain from the door wider to one side of the head, there may be visual disturbances, noise or tinnitus, balance disorders, dizziness, nausea and vomiting. Pain can be spread in one or both arms, and fingers can occur numbness in the fingers and arms along, decreased or increased sensitivity of the skin and loss of strength in his hand.

Just like all the other joints in your body, and neck joints tend to be subjected to abrasion in accordance with age, which can lead to osteoarthritis in the neck. Nerve compression. A herniated disc or bone marrow in the cervical vertebrae can cause pressure on the nerves of the spinal cord injury. Injuries. Auto collisions and accidents often result whiplash and neck injuries, which occur when the head is going backwards flick moves rapidly forward, it is stretching the soft tissues of the neck beyond their borders. Diseases. Neck pain can sometimes be caused by a disease, such as rheumatoid arthritis, meningitis or cancer.
Prevention and Exercise:
In the chronic phase, when reducing the intensity of pain and the spine becomes more mobile, applied for easing pain and spasms physical therapy, massage, electrotherapy and stretching. Physical therapy includes warm compresses, therapeutic ultrasound that serve as an introduction to kinesitherapy (movement therapy, medical gymnastics). Stretching, isometric exercises to strengthen the muscles, relieving exercises and posture exercises. It is important to emphasize the importance of medical gymnastics in the restoration and / or maintenance of the function of the cervical spine.
The exercises used in strengthening the neck muscles are generally static or mild and slow dynamic exercise. They should be run 3 times a week for 20 minutes.
Lightweight door rotation in all directions with a slight stretch. Around 12 rotation each side or 12 move up and down, left or right, slowly.
Pressure with hand in the opposite side of the carriage and the strengthening of the neck muscles with static contractions. Try to hold in position for couple of second and then change the side.
Strengthening Trapezius dorsal and cervical muscles, which is very important for proper posture and maintain the head in the proper position in the effort. The exercise is performed from a starting position with hands outstretched and pulling this towards the chin with a mandatory deflections elbows above shoulder level.
