在这项横断面人群研究中，78名健康的绝经后0.5-5年，49-55岁的女性发现腰椎LII-Liv骨密度与邻近的背伸、屈肌等长肌力之间存在显著的简单线性相关。逐步多元线性回归分析显示，体重(偏R2)(R2=0.197，p=0.0001；R2=0.157，p=0.0009)和年龄(R2=0.056，p=0.0205；R2=0.036，p=0.0708)是腰椎LII-Liv和股骨颈骨密度最显著的预测因素。身高、等长肌力和肌肉耐力不是显著的预测因子。体重和年龄也是等长肌力最显著的预测因子。脊柱活动度、体脂含量和无氧阈值与骨密度无相关性。
In this cross-sectional population study with 78 healthy 0.5-5 years postmenopausal, 49-55 year old females a significant simple linear correlation between lumbar spine LII-LIV bone mineral density and adjacent back extensor and flexor isometric muscle strength was found. With the stepwise multiple linear regression analyses the most significant predictors for lumbar spine LII-LIV and femoral neck bone mineral density were weight (partial R2) (R2 = 0.197, p = 0.0001; R2 = 0.157, p = 0.0009) and age (R2 = 0.056, p = 0.0205; R2 = 0.036, p = 0.0708). Height and isometric muscle strength and endurance of muscles were not significant predictors. Weight and age were the most significant predictors also for isometric muscle strength. The mobility of spine, body fat content and anaerobic threshold had no correlation on bone mineral density.
