Red face Sitting straight is bad for your back

Now if this new study is to be believed then all those ergonomics about your office chair and desk are out the window.

Quote:
Sitting straight 'bad for backs'
Sitting up straight is not the best position for office workers, a study has suggested.



Scottish and Canadian researchers used a new form of magnetic resonance imaging (MRI) to show it places an unnecessary strain on your back.

They told the Radiological Society of North America that the best position in which to sit at your desk is leaning back, at about 135 degrees.

Experts said sitting was known to contribute to lower back pain.

Data from the British Chiropractic Association says 32% of the population spends more than 10 hours a day seated.

Half do not leave their desks, even to have lunch.

Two thirds of people also sit down at home when they get home from work.

Spinal angles

The research was carried out at Woodend Hospital in Aberdeen, Scotland.

Twenty two volunteers with healthy backs were scanned using a positional MRI machine, which allows patients the freedom to move - so they can sit or stand - during the test.

Traditional scanners mean patients have to lie flat, which may mask causes of pain that stem from different movements or postures.

In this study, the patients assumed three different sitting positions: a slouching position, in which the body is hunched forward as if they were leaning over a desk or a video game console, an upright 90-degree sitting position; and a "relaxed" position where they leaned back at 135 degrees while their feet remained on the floor.

The researchers then took measurements of spinal angles and spinal disk height and movement across the different positions.

Spinal disk movement occurs when weight-bearing strain is placed on the spine, causing the disk to move out of place.

Disk movement was found to be most pronounced with a 90-degree upright sitting posture.

It was least pronounced with the 135-degree posture, suggesting less strain is placed on the spinal disks and associated muscles and tendons in a more relaxed sitting position.

The "slouch" position revealed a reduction in spinal disk height, signifying a high rate of wear and tear on the lowest two spinal levels.

When they looked at all test results, the researchers said the 135-degree position was the best for backs, and say this is how people should sit.

'Tendency to slide'

Dr Waseem Bashir of the Department of Radiology and Diagnostic Imaging at the University of Alberta Hospital, Canada, who led the study, said: "Sitting in a sound anatomic position is essential, since the strain put on the spine and its associated ligaments over time can lead to pain, deformity and chronic illness."

Rishi Loatey of the British Chiropractic Association said: "One in three people suffer from lower back pain and to sit for long periods of time certainly contributes to this, as our bodies are not designed to be so sedentary."

Levent Caglar from the charity BackCare, added: "In general, opening up the angle between the trunk and the thighs in a seated posture is a good idea and it will improve the shape of the spine, making it more like the natural S-shape in a standing posture.

"As to what is the best angle between thigh and torso when seated, reclining at 135 degrees can make sitting more difficult as there is a tendency to slide off the seat: 120 degrees or less may be better."

So Cha,its time to change your office chair

Write a mail to the concerned department


I stopped believing in all these researches,its like they frame question to get the desired answer they want.

Earlier theys said coffee increases your cholestrol,triglyceride and sugar level now one new research says that it can save your heart

Earlier research said sex and masturbation could cause prostate enlargment and now newer research says frequent masturbation and sex can shrink the enlarged prostate or keep it healthy.

One team says a thing and another says just the opposite.

Re: Sitting straight is bad for your back

Bhai woh jo correct position dikhaya usme poora stress back sey utarke neck par aajayega especially if you work with a computer. So rather than back you will contract neck problems.

Go to some site and search for correct neck postures to avoid spondylytis.

Re: Sitting straight is bad for your back

I think, it is better to have a adjustable robot arm to hold the laptop at any angle and have it tilted towards you while you rest in 135 deg as shown in this figure, that way neck need not slouch forward.

The worst position for neck is to crane forward causing slip disk and neck pain.

Something roughly of this sort and I indeed have such arrangement with my reclining chair at home and it feels quite comfortable for both my neck and back.

Re: Sitting straight is bad for your back

YOu need to exercise and do exercises like air squats, then squats with weights. All these exercises make your back and spine strong and keep you in shape.

But that's what they used to say about straight back postures too. Soon now, we will have scientists claiming that air squats and squats with weights wear out your spine and cause hernia

fuck these scientists... I mean squats is something which is so well known even in Indian form of exercise in akhaadas (traditional gyms). Situps, pushups, all these are well known exercises, tried and tested for their benefits. Offcourse if you do them wrong, then you will fuck your body parts for sure.

So is the straight back posture, specially when sitting cross legged Indian style.

There was a study saying that the sit-ups or where you lie down and sit up and bend your head to your knees (or whatever it is called) is bad for your spinal cord. It wears your spinal cord down... if you do too many of them.

Re: Sitting straight is bad for your back

My chiropractor told me this too. I agree with the TS. I have back problems before since I always sleep while sitting.

I have an idea... If we make a magic chair with carefully aligned magnets at the bottom of the chair, and can showcase 10 people whose impotency is cured after sitting on the chair.... we can make millions.
