Isometric force response curve by electrically stimulated skeletal muscle contraction of twitch is important in order to judge the ability of the skeletal muscle and to distinguish disease state. In this report, we introduce a new mathematical model of the isometric force response curve, in order to estimate the muscle contraction behavior accurately. The new mathematical model of force response curve was expressed by a difference of fundamental function which was expressed by products of a step response function and a logistic function. The mathematical model was applied to the force response curve by electrically stimulated muscle contraction of twitch, using the rat gastrocnemius muscle (GC), intermediate vastus muscle (VI) and soleus muscle (SOL) . The results indicate new mathematical model showed better agreement with the force response curve of twitch than previous mathematical model in the rat skeletal muscle which has different muscle fiber type only changes the model parameters.

<p>骨格筋収縮に起因する微細な振動を記録した筋音図MMG (mechanomyogram) は, 筋の機械的な収縮機能を反映しているが, 強縮時における筋の断面積方向の変位を測定した報告は少ない. 著者らはヒト大腿直筋 (type Ⅱ線維優位) および短母指外転筋 (type Ⅰ線維優位) の皮膚表面において, 30秒間に0.2 [Hz] から50 [Hz] まで連続的に電気刺激の周波数を増加させたときのMMGを, レーザ変位計によって測定し, 骨格筋の強縮特性について検討した. 実験は筋疾患のない21～25歳の男性3名, 女性1名で行った. 本実験より, (1) 異なる筋線維タイプが混在する骨格筋は, 二段階的に不完全強縮が進行し, 筋線維の構成比によって変位MMGの大きさが異なる, (2) 一般的なtype Ⅰ, type Ⅱ線維の単収縮 (筋張力) の収縮時間と弛緩時間から, 強縮過程における変曲点の周波数域を推定した結果, 最初に起こる不完全強縮はtype Ⅰ線維, 続いて起こる不完全強縮はtype Ⅱ線維の周波数域とほぼ一致する, ことがわかった.</p>
