肌肉形态、年龄和性别可能是老年人肌肉力量的决定因素。然而，很少有研究直接检验衰老脊柱中的这种相关性。该研究的目的是检查老年人和年轻人的腰伸肌力量、肌纤维角度、胸腰椎曲度、年龄和性别之间的相关性。对 26 名年轻（平均年龄 27.9，SD 5.2）和 26 名老年（平均年龄 72.1，SD 5.9）参与者的腰伸肌肌纤维角度、胸腰椎曲度和腰伸肌力量进行了检查。采用皮尔逊相关系数来确定腰伸肌纤维角度、胸腰椎曲度、年龄、性别和腰伸肌力量之间的关联。使用多元逐步线性回归分析来确定腰伸肌力量的重要决定因素。结果表明，腰伸肌力量、肌纤维角度、年龄和性别之间存在显着相关性。在逐步回归分析中，性别和年龄被认为是老年人腰伸肌力量最有力的决定因素。然而，性别是年轻人肌肉力量的唯一决定因素。这些结果表明，与年轻人相比，老年人腰伸肌力量的下降更依赖于年龄。
Muscle morphology, age and gender may be determinants of muscle strength in older adults. However, very few research studies have directly examined such correlation in the ageing spine. The aim of the study was to examine the correlation between lumbar extensor muscle strength, its muscle fibre angles, thoracolumbar curvature, age and gender in the older and younger adults. Muscle fibre angles of lumbar extensor muscles, thoracolumbar curvature and lumbar extensor muscle strength were examined in 26 young (mean age 27.9, SD 5.2) and 26 older (mean age 72.1, SD 5.9) participants. Pearson’s correlation was employed to determine the association among lumbar extensor muscle fibre angle, thoracolumbar curvature, age, gender and lumbar extensor muscle strength. Multiple stepwise linear regression analysis was used to identify significant determinants of lumbar extensor muscle strength. The results demonstrated a significant correlation between lumbar extensor muscle strength, muscle fibre angle, age and gender. In the step wise regression analysis, both gender and age were identified as the most robust determinant for lumbar extensor muscle strength in older adults. However, gender was the only determinant of muscle strength in the young. These results suggest that the decline in the lumbar extensor muscle strength in older adults was more dependent on age when compared to younger adults.
