为探讨长期日常训练对运动员骨骼肌的影响，本研究测定了运动员骨骼肌厚度与被动肌僵硬度的关系，并对运动员和非运动员骨骼肌厚度和肌肉僵硬度进行了比较。参加者是来自各种体育项目的日本精英运动员（278名男子，200名妇女）和非运动员（35名男子，35名妇女）。使用B型超声测量股直肌（RF）肌肉厚度，并将其标准化为总体重（肌肉厚度/体重（1/3））。通过超声剪切波弹性成像评估RF被动肌肉刚度（剪切模量）。男性运动员的肌肉厚度和肌肉硬度之间存在可忽略的显著相关性（p=0.003; r=-0.18），但女性运动员的相关性不显著（p=0.764; r=0.02）。在男性中，运动员的肌肉厚度显著大于非运动员（p
To examine the effect of long-term daily training on athletes' skeletal muscle, this study determined the relation between their muscle thickness and passive muscle stiffness, and compared the muscle thickness and muscle stiffness between athletes and non-athletes. Participants were elite Japanese athletes (278 men, 200 women) from various sports and non-athletes (35 men, 35 women). Rectus femoris (RF) muscle thickness was measured using B-mode ultrasonography and was normalized to the total body mass (muscle thickness/body mass(1/3)). RF passive muscle stiffness (shear modulus) was assessed by ultrasound shear-wave elastography. There was a negligibly significant correlation between muscle thickness and muscle stiffness in male athletes (p=0.003; r=-0.18) but not in female athletes (p=0.764; r=0.02). Among men, muscle thickness was significantly greater in athletes than non-athletes (p
