This study analyzed the effect of lumbar support belts on functional performance.
To compare lumbar muscle strength and lifting capacity with and without a lumbar belt.
Industrialized settings have begun to encourage the use of lumbar support belts for their employees. It is believed that the belts may decrease the risk of injury and enhance the functional performance of the individual.
Twenty-two subjects (average age, 27.5 years) were tested on four separate days to evaluate the effect of a commercially available belt on isolated lumbar isometric strength and functional dynamic lifting capacity. All subjects had no history of low back problems. The order of testing with and without a belt was randomized for both conditions. On the first 2 days, subjects performed a seven-angle isometric lumbar extension strength test, 1 day with and 1 day without a lumbar belt. On the following 2 days, subjects were tested to evaluate functional capacity with and without a lumbar belt. The functional capacity evaluation was performed by progressively lifting weighted canisters from various levels. Heart rates were monitored to ensure that a maximum effort was achieved over the different days.
T tests revealed that isometric lumbar strength and functional lifting capacity was not significantly affected by the belt.
The use of a lumbar belt does not enhance isometric lumbar muscle strength or dynamic lifting capacity.
本研究分析了腰部支撑带对功能表现的影响。
比较使用和不使用腰部支撑带时的腰部肌肉力量及举重能力。
工业化工作环境已开始鼓励员工使用腰部支撑带。人们认为这种腰带可能会降低受伤风险并提高个人的功能表现。
22名受试者（平均年龄27.5岁）在四个不同日期接受测试，以评估一种市售腰带对孤立的腰部等长肌力和功能性动态举重能力的影响。所有受试者均无腰痛病史。两种情况下使用和不使用腰带的测试顺序均随机安排。在前两天，受试者进行了七角度的腰部等长伸展力量测试，一天使用腰部支撑带，一天不使用。在接下来的两天里，受试者接受测试以评估使用和不使用腰部支撑带时的功能能力。功能能力评估通过从不同高度逐步举起加重的罐来进行。监测心率以确保在不同日期都达到了最大努力。
t检验显示，腰部支撑带对腰部等长肌力和功能性举重能力没有显著影响。
使用腰部支撑带并不能增强腰部等长肌肉力量或动态举重能力。
