The Three Worst Exercises For Low Back Pain
Three of the most common exercises purported to reduce back pain
actually can cause more harm than good. In fact, some of these exercises
are downright dangerous. Given the frequency with which these harmful
exercises are prescribed, it is not surprising that most people
experience back pain at some point in their life and typical medical
treatment is not effective for reducing the pain.
The first
harmful exercise is the "Superman", which involves laying down on your
stomach and lifting up your arms and legs. This causes a strong
contraction in the lower back.
The primary reason that this
exercise is dangerous is that any time you hyper-extend your spine, the
facet joints (one of the joints between adjacent vertebrae) are
compressed in a compromising position. The facet joints are incredibly
sensitive and often the site of many people's back pain.
Adding a
muscular contraction in this position can result in forces in excess of
6000 Newtons (a Newton is a unit of force). To get an idea of what this
type of force means, the NIOSH, which is a safety organization run by
the American government, states that the maximum allowable force in the
workplace is 6700 Newtons.
The "Superman" exercise approaches the
maximum safe level of force spinal compression in a hyper-extended
(compromised) position, making this exercise a true spine destroyer.
The
deceptive thing about this exercise is that usually motion (of any
kind) provides relief at first, so this exercise might temporarily
reduce pain. However, given the damage it can cause to the facet joints,
this exercise is bound to increase back pain levels over time.
The
second harmful exercise is the crunch or sit-up. It does not matter
whether or not this exercise is performed with the knees bent, straight,
as a full sit-up, just a crunch, or on a Swiss ball; this exercise will
inevitably cause damage to the spine.
This is counter-intuitive
as the popular belief is that increasing "core" strength will reduce
back pain. The truth is that increasing abdominal strength is not
associated with back pain at all (however, muscular endurance does
protect against back pain).
The problem with the crunch is that
lab research has discovered that the easiest way to herniate a disc is
to repetitively perform flexion (flexing) to extension (straightening
back to normal) movements (a crunch involves flexing then extending the
spine repeatedly).
As a result, performing crunches can increase
disc wear and tear in addition to ultimately creating or worsening
herniated discs.
The final exercise is the side-crunch. This
exercise for the obliques involves holding a dumbbell or weight in the
hand and then bending down to the side and back up. This is bad for the
back for the same reasons that a crunch is: repeatedly flexing and
extending (straightening) the spine is liable to herniate a disc
