UNDERSTANDING THE CORE: WHAT YOU NEED TO KNOW

In fitness today, strengthening the core” is a hot topic. What most people don’t realize is that the core is more than just abdominal muscles. It is a combination of static and dynamic stabilizers of the lower back, pelvis and hip joints that work together to restrict or produce movements of these segments. Understanding how the core is structured will give you better insight into preventing back injuries and alleviating lower back pain.

The core consists of abdominal, lower back and buttock muscles, along with hip abductors and hamstrings. Acting in an harmonious fashion they ensure that the back, hips, knees and ankles do not get injured. This is analogous to a classical music concert when one member of the orchestra is out of rhythm, then the whole concert is meaningless.

Many back injuries occur because of a weak core. This does not imply that all of the muscle groups are weak. All that is necessary is to have one or two of the muscle groups weaker than the other ones and the person loses his/her ability to stiffen or stabilize the lower back for that specific activity. The harmonious firing of these muscle groups helps tremendously to off load the disc and joints in the lower back.

The major buttock muscle (gluteus maximus) is extremely important in transferring the work load between the hip abductors/hamstrings and abdominal/lower back muscles. The hip abductors (gluteus medius and minimus) are critical in leveling the pelvis and stabilizing the knee. Abdominal and lower back muscles (rectus abdominis, transverse abdominis, erector spinae, mutifidus, quadratus lumborum) are significant for increasing intra-abdominal pressure and thus stiffening and protecting the lower back. The hamstrings with the help of the gluteus maximus are responsible to support and work synergistically with lower back and abdominal muscles.

One of the mainstays of conservative management in patients who experience low back pain is to restore that person’s core. A routine gentle strengthening and flexibility program is most important. Exercises such as Pilates, gentle Yoga or Swiss Ball strengthening can be incorporated into a 15-minute, three-time-per-week program with amazing results.

Endurance training is as equally important as strength training. Most of the time injury happens when the muscles are fatigued and loose their ability to protect the lower back.

Under the guidance of a good physical therapist, chiropractor, personal trainer, or athletic trainer, one can achieve a strong and balanced core. It is extremely important that the trainer or the therapist be familiar with the specifics and the proper form of the exercises, otherwise, you can actually make your condition worse. Especially for those with persistent back injuries or pain, it would be wise to consultant with a board certified physician before starting any exercise program.

In the beginning, these muscle groups are isolated, but over time as you advance, all are combined in the final phase of the training. Once your body learns the neuromuscular pathways, your core becomes engaged in your activities without you being aware of it.

This is how you can avoid injuring your back as well as recover from lower back injury or surgery. And most important of all, use common sense; if you are in pain after a training session, then your are most likely doing the wrong exercise and/or using the wrong form.
