The relationship between objectively measured physical and mental functional capacity and work ability was studied among 137 workers with a mean age of 55 years. Of the physical capacity tests muscular strength correlated the best with the constructed work ability index. Cardiorespiratory capacity and work ability did not correlate statistically significantly. About 50% of the subjects was classified uniformly, and less than 10% not uniformly, with respect to muscular strength. The correlation between cardiorespiratory capacity and work ability was significant for those without, but not for those with, a musculoskeletal disease. The mental capacity tests had systematically lower correlations with work ability than the tests for physical capacity. The highest statistically significant correlation was found between visuomotor speed and work ability. Objective measurements of muscular strength seem useful for defining work ability, but other tests need to be improved to be more work-related. Furthermore, musculoskeletal diseases should be checked for when cardiorespiratory capacity is assessed.
在137名平均年龄为55岁的工人中，研究了客观测量的身体和心理功能能力与工作能力之间的关系。在身体能力测试中，肌肉力量与构建的工作能力指数相关性最佳。心肺功能能力与工作能力在统计学上无显著相关性。就肌肉力量而言，约50%的受试者分类一致，不到10%的受试者分类不一致。对于没有肌肉骨骼疾病的人，心肺功能能力与工作能力之间存在显著相关性，但对于患有肌肉骨骼疾病的人则不然。与身体能力测试相比，心理能力测试与工作能力的相关性系统性地更低。在视觉运动速度与工作能力之间发现了最高的统计学显著相关性。肌肉力量的客观测量似乎有助于定义工作能力，但其他测试需要改进，使其更与工作相关。此外，在评估心肺功能能力时应检查是否存在肌肉骨骼疾病。
