The objective of our investigation was to study isometric lifting strength in a population of industrial workers who perform a great variety of manual tasks, and to determine whether isometric strength is predictive of future back problems in such a population. Of 3,020 study subjects, 2,178 (72%) underwent strength testing in three standard lifting positions. During a 4-year follow-up period, 172 subjects tested reported back problems. When examining each isometric lift separately as a predictor of industrial back pain reports, those with greater isometric strength were at significantly greater risk than were weaker workers. However, after controlling for the effects of age, only a slight trend remained. For the blue collar workers in this study, isometric lifting strength testing was ineffective in identifying individuals at risk for industrial back problems.
我们调查的目的是研究从事各种体力劳动的产业工人的等长举重力量，并确定等长力量是否能预测这类人群未来的背部问题。在3020名研究对象中，2178名（72%）在三个标准举重姿势下接受了力量测试。在4年的随访期内，172名接受测试的受试者报告了背部问题。当分别将每次等长举重作为工业背痛报告的预测指标进行检查时，等长力量较强的工人比力量较弱的工人患背痛的风险显著更高。然而，在控制了年龄的影响后，仅剩下轻微的趋势。对于本研究中的蓝领工人，等长举重力量测试在识别有工业背部问题风险的个体方面无效。
