一些研究已经调查了超声测量的肌肉厚度（MT）和个体肌肉横截面积（CSA）和肌肉体积（MV）之间的关系，在四肢和躯干肌肉;然而，腘绳肌尚未研究。本研究的目的是探讨股后MT的超声和肌肉CSA和MV的腘绳肌磁共振成像（MRI）获得的关系。10名20-31岁的年轻女性在大腿内侧前（大腿长度的50%; TL）和后（TL的50%和70%）三个部位通过超声测量MT。同一天，通过MRI测量了一系列沿大腿沿着的连续肌肉CSA。在每个切片中，分析腘绳肌（股二头肌、半腱肌和半膜肌）和四头肌的解剖CSA，并确定TL的50%和70%时的CSA和腘绳肌的最大CSA（CSA（max））。通过CSA乘以切片厚度计算MV。在后部50% MT和50%腘绳肌CSA之间观察到显著相关性（r=0848，P=0002），在后部70% MT和70%腘绳肌CSA之间观察到显著相关性（r=0679，P=0031）。后50%MT（r=0732，P=0016）和50%MTxTL（r=0873，P=0001）也与腘绳肌MV相关。大腿前：后50% MT比与股四头肌和腿筋肌肉MV比相关（r=0803，P=0005）。我们的研究结果表明，股后MT反映了腘绳肌CSA和MV。前：后MT比可以作为股四头肌和腘绳肌MV比的替代。
Several studies have investigated the relationship between ultrasound-measured muscle thickness (MT) and individual muscle cross-sectional area (CSA) and muscle volume (MV) in extremity and trunk muscles; however, the hamstring muscle has not been studied. The purpose of this study was to examine the relationship between posterior thigh MT by ultrasound and the muscle CSA and MV of the hamstring obtained by magnetic resonance imaging (MRI). Ten young women aged 20-31 had MT measured by ultrasound at three sites on the medial anterior (50% of thigh length; TL) and posterior (50% and 70% of TL) aspects of the thigh. On the same day, a series of continuous muscle CSA along the thigh was measured by MRI. In each slice, the anatomical CSA of the hamstring (biceps femoris, semitendinosus and semimembranosus) and quadriceps muscle was analysed, and the CSAs at 50% and 70% of TL and maximal CSA of the hamstring (CSA(max)) were determined. MV was calculated by multiplying CSA by slice thickness. A significant correlation was observed between posterior 50% MT and 50% hamstring CSA (r=0848, P=0002) and between posterior 70% MT and 70% hamstring CSA (r=0679, P=0031). Posterior 50% MT (r=0732, P=0016) and 50% MTxTL (r=0873, P=0001) were also correlated to hamstring MV. Anterior:posterior 50% thigh MT ratio was correlated to MV ratio of quadriceps and hamstring muscles (r=0803, P=0005). Our results suggest that posterior thigh MT reflects hamstring muscle CSA and MV. The anterior:posterior MT ratio may serve as a surrogate for MV ratio of quadriceps and hamstring.
