Use
of Lifting Belts During Strength Training Workouts
By David Petersen
The decision of whether
to use a lifting belt during exercise should be guided by the following
information:
As mentioned in an earlier
article on lower back pain, the deep stabilizing muscles of the
lumbo-pelvic region (core) are suspected as having a “drum
forming” effect – that is the muscles contract simultaneously
in a reflex (no conscious thought required in people without back
pain) action to help stabilize the low back and allow forces to
be transferred from the lower body to the upper body and vice versa.
This action also has the effect of compressing the abdominal contents
- composed primarily of water and very little gas; thus the name
of this phenomenon is the “fluid ball” effect. Water
as a liquid is essentially incompressible, so you can see how the
presence of an internal pressurized fluid “ball” will
lend stability to the pelvis and spine and actually help generate
torque in the lift. For example, as you descend into a heavy squat,
the muscles of the core and diaphragm begin to contract and generate
tension on the fluid ball. As you squat deeper and your knees and
hips flex more and more, the pelvis starts to tip forward and the
large erector spinea muscles begin to lose their strength advantage
due to a decreased muscle length. It is logical then to assume that
the fluid ball acts as a “block” to prevent excessive
spinal flexion and possible compressive damage to the intervertebral
ligaments and discs.
Lifting belts
have been demonstrated to have a similar effect of passively increasing
intra-abdominal pressure simply by the mechanics of their operation.
However, when a lifting belt is used on a consistent basis, it is
proposed that the inner stabilizing muscles and deep abdominals
are relieved of much of their duty and fail to get stimulated sufficiently.
Therefore, even though you may be performing a very functional movement
like a squat, you are receiving a source of external stabilization
likened to that provided by machine exercise. The risk of using
a lifting belt for all lifts is that the core muscles are not trained
sufficiently and in the correct motor sequence, so if you attempt
a heavy lift without a lifting belt, there may be an increased chance
of injuring your back. The best advice then is if you are going
to use a lifting belt, use it only when you attempt maximal (1RM)
lifts and only when the spine is directly targeted like in a squat.
Perform submaximal lifts without a belt to ensure sufficient training
of the deep stabilizers of the spine. (It should be kept in mind
however that some world class Olympic-style weightlifters never
use weightlifting belts).
So if your goal is to
wear a lifting belt on the field or track or even while performing
regular everyday tasks, then use a belt for all your lifts. If however
you want “true” functional strength and power, train
your own “internal weight lifting belt” and discard
the “fake” one.
