本研究调查了在没有肌肉张力的情况下，肌肉的厚度和硬度的组合是否可以用来估计成年男性和女性膝关节伸展时的肌肉力量。72名男性和33名女性参加了这项研究，年龄从18岁到35岁不等。我们使用超声肌肉硬度计测量了在没有肌肉紧张的情况下大腿右前区（股直肌和股中间肌）的肌肉厚度和硬度，以及右膝关节伸展的最大自愿等距收缩（MVIC）。计算压缩前组织厚度与压缩过程中组织厚度的变化率（压缩比）作为硬度的指标。比率越高，表明与其他肌肉厚度相同的个体相比，肌肉更硬。在男性组，MVIC与肌肉厚度（r=0.412, p<0.01）和压缩比（r=0.233, p<0.05）均呈显著正相关，但其变量之间也存在相关性。在女性组中，MVIC仅与压迫比呈正相关（r=0.499, p<0.01），与肌肉厚度无关（r=0.225, n.s）。在多元线性回归分析中，两个参数（肌肉厚度和压缩比）的组合可以更准确地估计女性组的MVIC （r=0.573, p<0.01）。这些发现表明，结合肌肉厚度和硬度能够有效地估计肌肉力量，特别是在女性中。
The present study investigated whether a combination of the thickness and hardness of muscles without muscle tension can be used to estimate muscle strength during knee extension in adult males and females. Seventy-two males and thirty-three females, whose ages ranged from 18 to 35 years, participated in this study. We measured muscle thickness and hardness in the right anterior region of the thigh (rectus femoris muscle and vastus intermedius muscle) without muscle tension using an ultrasound muscle hardness meter, and the maximal voluntary isometric contraction of right knee extension (MVIC). The changing ratios (%) of the tissue thickness before compression to those during compression (compression ratio) are calculated as an index of the hardness. Higher ratio indicates a harder muscle compared with that of other individuals showing the same muscle thickness. In male group, although the MVIC had significantly positive correlation to both muscle thickness (r=0.412, p<0.01) and compression ratio (r=0.233, p<0.05), their variables also had correlation mutually. In the female group, the MVIC has significantly positive correlation to only compression ratio (r=0.499, p<0.01), not muscle thickness (r=0.225, n.s.). On multiple linear regression analysis, the combination of two parameters (muscle thickness and compression ratio) allowed more accurate estimation of MVIC (r=0.573, p<0.01) in the female group. These findings suggested that the combination of muscle thickness and hardness is capable of effectively estimating muscle strength especially in females.
