Ultrasound imaging was used to investigate vastus medialis (VM) architecture in 10 males and 10 females at different knee angles. Increase in muscle thickness occurs predominantly when the knee angle is changed from 0° (full extension) and 45° (p < 0.05); increases in VM pennation angle can be predominantly observed between 45° and 90° (p < 0.05). Sex differences in the VM architecture can be observed in the distal (p < 0.01) but not in the proximal region of the muscle (p > 0.11).
超声成像技术用于研究 10 名男性和 10 名女性在不同膝关节角度下股内侧肌（VM）的结构。当膝关节角度从 0°（完全伸展）变为 45°（p＜0.05）时，肌肉厚度主要增加；当膝关节角度从 45°变为 90°（p＜0.05）时，VM 羽肌角的增加主要观察到。在肌肉的远端（p＜0.01）可以观察到 VM 结构的性别差异，但在肌肉的近端（p＞0.11）则观察不到。
