This study was performed to develop and evaluate a scheme for matching the strength of workers to the strength demands of their jobs. Biomechanical analyses were performed on production jobs in an aluminum reduction plant to identify and quantify strength demands. These data were used to design a set of nine strength tests which simulated job activities with the greatest strength requirements. A cross section of plant employees assigned to these jobs was strength tested and monitored for medical incidents for a period of over two years. Significant relationships were found among job strength requirements, worker strengths, and medical incidents. Workers with strength abilities (as determined by the tests) less than job strength requirements suffered a higher rate of medical incidents than workers whose strength abilities matched or exceeded job demands. It was concluded that strength testing can be used to identify workers who would be at increased risk of suffering medical incidents if placed on jobs which exceeded their strength abilities.
本研究旨在制定并评估一种将工人力量与工作强度需求相匹配的方案。对一家铝冶炼厂的生产工作进行了生物力学分析，以确定并量化强度需求。这些数据被用于设计一组九项力量测试，这些测试模拟了强度要求最高的工作活动。对分配到这些工作岗位的一组工厂员工进行了力量测试，并对医疗事故进行了两年多的监测。发现工作强度要求、工人力量和医疗事故之间存在显著关系。力量能力（由测试确定）低于工作强度要求的工人比力量能力与工作需求相匹配或超过工作需求的工人遭受医疗事故的比率更高。得出的结论是，力量测试可用于识别如果从事超出其力量能力的工作将面临更高医疗事故风险的工人。
