Eyal Lederman The principle of core stability has gained wide acceptance in training for the prevention of injury and as a treatment . Someone recently sent me the above paper that was published a few years ago, The Myth Of Core Stability, by Professor Eyal Lederman.

Even if we could effectively re-train muscle timings, that would mean interfering with a complex mechanism that our bodies use to protect us from further injury. You could go around the timing problem by activating TrA all the time. But this way you use a force that is often more than what you need to efficiently perform a task, unnecessarily compressing the lumbar spine.

Also tensing of the abdominal muscles increases intra-abdominal pressure which in some cases e. If you learn to activate TrA while lying on your back, there is no guarantee that this would transfer to control and physical adaptation during standing, sitting, bending, lifting, running.

The Myth Of Core Stability

Which basically means, the only way to strengthen the body to be able to respond to various positions is to use it in all of these. Or in other words — to MOVE. Which made me think, our hunter-gatherer ancestors never went to a gym and probably never ever thought of doing any core strengthening and still had enough core strength to survive in wilderness hunting their lunch.

But the thing is, they moved — all day, every day, more in summer, less in winter, but at least a couple of miles every day.

They climbed trees, carried their children, sat on the ground to prepare their food and eat. And none of them ever even heard of core stability. Our modern weak core epidemic, sort of, is a response to the way we live and use our bodies day to day — driving everywhere, spending most time sitting on couches and comfortable chairs.

There is rarely any need to use your strength, unless maybe sometimes carrying a suitcase up the stairs when the lift is out of order or occasionally moving a piece of furniture. And then you throw your back out. Can 3—5 hours in the gym offset the rest of the week spent sitting, pretty much in one position every day from nine to five? The same as what we eat shapes us, the way we move over time shapes us too.

Not just exercise, but every movement and lack there of counts. Our bodies have adapted to very limited use and repetitive positioning of the joints throughout the day. Through using the body more and in more ways, we can restore mobility in the stiff areas and allow muscles to do their job in stabilising the body as we move.

We need to bring movement back into the way we live, bit by bit.

Core Strength Defined

Not only in the gym. Bowman makes a parallel between movement and nutrition in which exercises are an equivalent of vitamins — useful as a supplement only, but not able to replace eating well altogether. A healthy movement diet looks something like this: Walking, walking , walking Squatting and sitting on the floor Lifting and carrying Hanging and climbing So the same as we make effort to eat our 5 servings of fruits and veggies per day, we need to make sure to squeeze in at least a bit of each of these types of movements in our day as the main source of our movement nutrients.

The body stabilises itself in response to movement. Our feet and hands behave as sensory organs giving us information through a level of joint distortion.

And even looking deeper into the body — our muscles not just execute the movement but also react to the sensory input of the environment, tensing and releasing when needed. And this is basically the same view I found in work of dance educator Hubert Godard — there is no need to keep the tension in the centre but allow the body to respond freely to movement, gliding fluidly between the earth and the sky.

Walk, squat, use your arms more and in more ways, climb a tree if you can. No exercise programme can strengthen a body which is not being used otherwise. And release the belly — instead of keeping it pulled in all the time, leaving space for the body to stabilise itself as and when needed. How essential is TrA for spinal stabilisation? One way to assess this is to look at situations where the muscle is damaged or put under abnormal mechanical stress.

The myth of core stability.

Would this predispose the individual to lower back pain? It would be interesting to see how these individuals stabilise their trunk and whether they suffer more back pain. Pregnancy is another state that raises some important questions about the role of TrA or any abdominal muscle in spinal stabilisation.

During pregnancy the abdominal wall muscles undergo dramatic elongation, associated with force losses and inability to stabilise the pelvis against resistance Fast et al. Indeed, in a study of pregnant women n Z they were shown to have lost the ability to perform situps due to this extensive elongation and subsequent force losses Fast et al.

Whereas all non-pregnant women could perform a sit-up, However, there was no correlation between the sit-up performance and backache, i. Despite this, CS exercises are often prescribed as a method for retraining the abdominal muscles and ultimately as a treatment for LBP during pregnancy.

There is little evidence that localised musculoskeletal mechanical issues, including spinal stability play a role in the development of LBP during pregnancy. Another interesting period for us, concerning the role of abdominal muscles and stabilisation is immediately after delivery.

Postpartum, it would take the abdominal muscle about 4e6 weeks to reverse the length changes and for motor control to reorganise. For example, rectus abdominis takes about 4 weeks postpartum to re-shorten, and it takes about 8 weeks for pelvic stability to normalise Gilleard and Brown, Would this increase the likelihood for back pain?

In a recent study, the effects of a cognitive-behavioural approach were compared with standard physiotherapy on pelvic and lower back pain immediately after delivery Bastiaenen et al. An interesting aspect of this research was that out pregnant women suffering from back pain during pregnancy, were excluded because of their spontaneous unaided recovery within a week of delivery.

This spontaneous recovery was during a period, well before the abdominal muscles had time to return to their pre-pregnancy length, strength or control Gilleard and Brown, Yet, this was a period when back pain was dramatically reduced.

How can it be that back and pelvic pain is improving during a period of profound abdominal muscle inefficiency?

Why does the spine not collapse? Has the relationship between abdominal muscles and spinal stability been over-emphasised? One would expect, as in pregnancy, the distension of the abdomen to disrupt the normal mechanics and control of the trunk muscles, including TrA.

According to the CS model this should result in an increased incidence of back pain among this group. Yet, epidemiological studies demonstrate that weight gain and obesity are only weakly associated with lower back pain Leboeuf- Yde, According to the CS model we should be seeing an epidemic of back pain in over-weight individuals.The major muscles involved in the core are: the abdominals in the front; the obliques on the side; and the latissimus dorsi, the erector spinae and the glutes in the back.

Making contacts is about giving, offering yourself to others. The Myth of Core Stability by Professor Eyal Lederman The principle of core stability has gained wide acceptance in training for prevention of injury and as a treatment modality for rehabilitation of various musculoskeletal conditions in particular the lower back. I am always a fan of the counter-intuitive approach and after reading it I can say that everything posited in the paper is accurate but I can also say that the findings are not particularly useful to me.

Patients who have been trained to use complex abdominal hollowing and bracing manoeuvres should be discouraged from using them. And this creates a sense of separation and alienation. Did it really help low back pain? Everyone usually agrees that basic core exercises are beneficial, but the question became: What did it benefit?

The research in trunk control has been an important contribution to the understanding of neuromuscular reorganisation in back pain and injury.

Remember, too, that it has three-dimensional depth and therefore uses all three planes of motion.
