项目摘要
Muscles have different functions during locomotion (e.g. motor, brake,spring). This study investigates whether there are adaptions in muscleproperties according to these functions. For this purpose, the two rat muscles - M. gastrocnemius (Caput mediale) and M. quadriceps femoris(Vastus lateralis) - are compared experimentally as well as insimulations of muscle contractions. The latter requires a muscle modelwhich is able to predict the history-dependence of muscle force,namely force-depression after muscle shortening and force-enhancementafter muscle stretch. In the previous funding period we developed aphysiologically motivated model which for the first timerealistically predicts lengthening-induced force enhancement.In this last funding period (one year) it is necessary to enhance theexisting muscle model with regard to shortening-induced forcedepression. Using the enhanced muscle model we will performsimulations of muscle contractions to compare the muscles with respectto their functions (motor, brake, spring) during locomotion. Uponconclusion of the project a better understanding of functional muscleadaptations on the level of muscle properties will be achieved.
运动时肌肉有不同的功能(如马达、刹车、弹簧)。这项研究调查了根据这些功能是否存在肌肉特性的适应性。为此,我们在实验和模拟肌肉收缩时比较了两种大鼠肌肉——腓肠肌(股内侧肌)和股四头肌(股外侧肌)。后者需要一个肌肉模型,能够预测肌肉力的历史依赖性,即肌肉缩短后的力下降和肌肉拉伸后的力增强。在之前的资助期间,我们开发了生理动机模型,这是第一次现实地预测延长引起的力增强。在最后一个资助期(一年),有必要加强关于缩短引起的力抑制的现有肌肉模型。使用增强的肌肉模型,我们将进行肌肉收缩的模拟,以比较肌肉在运动过程中的功能(马达,制动器,弹簧)。该项目结束后,将在肌肉特性水平上更好地了解功能性肌肉适应。
