本研究探讨了背带的设计对竖脊肌活动、手部力量和身体稳定性的影响。该带首先用静态保持任务进行测试，发现其显著降低背部肌肉活动。进一步进行了实际吊装任务，以检验皮带的效果。10名男性受试者进行了对称的提升任务的低洼负荷（11和16公斤）在自然搬运速度，使用蹲或弯腰提升姿势，无论是有和没有带。该研究使用肌电图（EMG）、称重传感器和运动捕捉设备测量了各种独立变量。结果表明，该带减少了竖脊肌以及肱三头肌和肱二头肌的负荷。佩戴安全带时，峰值（手）力的总体平均值未受到显著影响，但力峰值出现延迟。安全带在举重时不会改变身体的稳定性。从目前的研究结果来看，腰带有效地改变了举重过程中的力分布，至少减少了背部的肌肉负荷。该带可以是用于对称工业提升任务的潜在有用的装置。
This work investigated how wearing a new design of back belt affects erector spinae activity, hand force, and body stability. The belt was first tested with static holding tasks and found to significantly decrease the back muscle activity. Actual lifting tasks were further carried out to test the effect of the belt. Ten male subjects performed a symmetric lifting task of low-lying loads (11 and 16 kg) at natural toting velocity, using either a squat or stoop lifting posture, both with and without a belt. The study measured various independent variables using electromyography (EMG), load cells, and motion capture device. The results demonstrated that the belt reduced the load on the erector spinae, as well as the triceps brachii and biceps brachii. The overall mean values of the peak (hand) force did not appear significantly affected while wearing the belt, but the force peaks appeared postponed. The belt did not alter body stability while lifting. From the present findings, the belt effectively changed the force distribution during lifting, at least reducing the muscle load on the back. The belt may be a potentially useful device for symmetric industrial lifting tasks.
