Abstract
The purpose of this research was to measure changes in torso posture when a commercially available abdominal support belt was worn. In addition, this study investigated whether the belt affected static lift strength and predicted spinal compression of the L3/L4 intervertebral disc.
Eight males and eight females were asked to perform maximal static exertions on handles attached to a steel rig. Lifts were performed from symmetric and asymmetric positions at different heights while the support belt was worn and not worn.
It was found that static lift strength and torso posture, with the exception of axial twist, were not significantly affected by belt use. Axial twist for low asymmetric exertions was significantly larger when the belt was worn as compared to when the belt was not worn. Predicted spinal compression was significantly lower when the belt was worn (2738 N) as compared to the nonbelt conditions (3087 N).
