A strength-training workout where you can stay put in one place? Sign me up. Hold up, though. The easiest example of an isometric move to think about is a plank. That muscle contraction is called an isometric contraction. A plank is just an isometric exercise, but many exercises actually incorporate all three movement patterns.
Nelson , Ph. In between that, when you stop and pause at the bottom? The same can apply to a biceps curl, if you add a hold to the move. If you paused halfway through and held the position at the top of the move, when your arm was at 90 degrees, that would be the isometric phase. Other examples of isometric exercises include wall sits, calf raises, and hollow-body holds. Famed strongman Alexander Zass credited much of his great strength to his isometric training as a prisoner during World War I.
He would push on the bars and chains that held him captive and quickly saw benefits. Not long after, he started promoting this method of training through his mail order courses. In simple terms, muscle can only contract in a few ways. It can do the obvious and contract to shorten the distance between joints, such as when doing a bicep curl. This is called a concentric contraction, where the muscle tenses while shortening. It can also tense while lowering a load, or resisting it, such as when lowering the weight in a curl.
This type of contraction is known as eccentric and occurs when the muscle tenses while lengthening. A final type of contraction is called an isometric contraction, and it occurs when the muscle tenses while not changing length. Examples of this are poses in body building or pushing against an immoveable object such as a wall.
One of the main benefits of isometric training is that the body is able to activate nearly all the available motor units - something that is usually very difficult to do. Another benefit of isometric training is simply the amount of time spent performing an exercise.
Consider an exercise like the bench press. It may take one to two seconds to perform with each joint angle only being trained for short periods of time. In contrast, an exercise that mimics the bench press, like a press against pins at the sticking point of the lift, may be performed for several seconds. In other words, if you have a problem at a particular joint angle in a lift, you can do targeted isometrics to quickly overcome your problems.
Secondly, there has been some selective use of the science involved in isometric research. Many will cite potential drawbacks such as decreases in coordination and speed of movement or decreases in muscle elasticity.
Like all good training methods, you need to know how and when to apply isometrics, and how to overcome whatever shortfalls it has. Every system has holes and it is your job as the trainer to overcome them. Potential decreases in muscle elasticity and speed of movement are easy to overcome with the use of relaxation and stretching methods between sets. Another reason physical therapists and doctors tend to use isometrics early on in your recovery process is the fact that isometrics are the fastest way to build strength.
When you are rehabbing, you want to improve as fast as you safely can to ensure the best recovery you can have.
So when you wonder do isometrics work, ask the next doctor, trainer, or physical therapist you encounter how they incorporate isometric exercises in their programs. The idea of cross-training is to exercise in a variety of different shapes, forms, and movements to confuse and expose your muscles to different exertions. Therefore, by the definition of cross-training, if you are not incorporating isometric strength training techniques into your workout you are shortchanging your training by leaving out a beneficial aspect to thoroughly cross-train.
The term functional fitness is indeed a great term and an idea the fitness industry created to create a buzz.
However, my question is, can you name a time when increasing your strength, regardless of how, is not functional to life activities? I cannot. The bottom line is more strength gives you more functionality and performance. When performed correctly with an emphasis on concentrating on your muscles engaged, intentional flexation, you are also developing neuro pathways to your muscles resulting in improved muscle coordination and pathways.
How many people are more built, athletic, and demonstrate incredible movements of what the human body is capable of than gymnasts, ballerinas, and yogis? That is right, when you ask or doubt if isometrics work, think about the performances and incredible poses, shapes, and explosive acrobatics from a yogi, ballerina, and gymnast. All three of the arts are loaded with isometric exercises during both their performances and training.
Doctors, physical therapists, and martial artists are a few practices that have proven through many training programs, results, and performances that isometrics do indeed work and should be incorporated into your exercise routines.
Isometric strength training techniques are proven to be the fastest way to build strength and deliver a plethora of advantages such as, affordability, convenience, efficiency, combatting age-related muscle loss, improved mental health, options for people with arthritis, and rehabilitation. Give it a try for a week and see for yourself if isometrics really do work. You will not regret your decision and may find adding isometric strength training to your routine gives you more time for doing what you love by making your routine more efficient.
