目的本研究旨在探讨年龄对上下肢和躯干肌肉的力学性能，肌肉大小和肌肉质量的影响。方法我们评估了83名健康女性（21-83岁）的上下肢和躯干肌肉的剪切模量（G），肌肉厚度（MT）和回声强度（EI）。在放松和伸展positions.ResultsRegarding年龄对G在不同的位置，G的上肢肌肉的G值进行了测量与年龄在放松和伸展的位置。相反，髂肌的G在两个位置上都表现出显著的负相关。此外，股直肌的G仅在放松位时呈显著负相关。关于身体部位之间的差异，下肢和腹斜肌的G显示出显著的负相关性，而上肢、腹直肌和背部肌肉没有相关性。此外，MT在下肢，腹部和竖脊肌与年龄呈显著负相关，但在上肢和腰多裂肌中未检测到相关性。结论年龄对G值的影响因部位而异，下肢和腹斜肌的G值与年龄呈负相关。此外，处于松弛位置的G可能比处于拉伸位置的G更容易老化。
PurposeThis study aimed to examine the effect of age on the mechanical properties, muscle size, and muscle quality in the upper and lower limb and trunk muscles.MethodsWe evaluated the shear modulus (G), muscle thickness (MT), and echo intensity (EI) of the upper and lower limb and trunk muscles of 83 healthy women (21–83-year-old). The G values of some limb muscles were measured in relaxed and stretched positions.ResultsRegarding the effect of age on G at the distinct positions, the G of the upper limb muscles were not significantly correlated with age in the relaxed and stretched positions. In contrast, the G of the iliacus showed a significant negative correlation in both positions. Additionally, the G of the rectus femoris had a significant negative correlation only in the relaxed position. Regarding differences among body parts, the G of the lower limb and oblique abdominal muscles showed a significant negative correlation, but no correlation in the upper limb, rectus abdominis, and back muscles. Moreover, MT showed a significant negative correlation with age in the lower limb, abdominal, and erector spinae muscles, but no correlation was detected in the upper limb and lumbar multifidus muscles. EI had a significant positive correlation in all the muscles.ConclusionThe effect of age on G depended on body parts, and the G of the lower limb and oblique abdominal muscles negatively associated with age. Additionally, G in the relaxed position may be more susceptible to aging than G in the stretched position.
