The largest calculated compressive force occurred in the weight belt condition (7 kN), and the smallest force was observed in the condition utilizing the weight belt with a rigid abdominal pad (6.51 kN).
The total times for the lifts were more variable but still not significantly different, with ranges between 1.43 s for the elastic binder condition and 1.59 s for the weight belt with abdominal pad.
Extensor moment 606.0 639.0 580.0 591.0 (N[multiplied by]m) (165.0) (215.0) (143.0) (150.0) Findings from the present study indicated that differences in IAP and its relieving force are minimal when comparing various belt designs inclusive of an abdominal pad. This is similar to the results of another study, which showed that wearing belts did not significantly increase IAP above that which could be achieved by holding [TABULAR DATA FOR TABLE 2 OMITTED] the breath (McGill, Norman, and Sharratt, 1990).
