开发了肌肉能量消耗模型，用于预测模拟肌肉收缩期间的热能和机械能释放。该模型旨在产生适合人体骨骼肌在正常体温下收缩的能量（热量和做功）率预测。本模型的基本形式类似于许多以前的肌肉能量消耗模型，但参数值几乎完全基于哺乳动物肌肉数据，并在可能的情况下优先考虑人类数据。还纳入了与次最大激活相关的非线性现象。肌肉能量模型以不同的复杂程度进行评估，从模拟孤立肌肉的收缩到模拟全身运动。在所有情况下，模拟和实验能量释放之间都存在可接受的一致性。本模型在未来使用正向动态计算机模拟研究人类运动的能量学中应该有用。
A model of muscle energy expenditure was developed for predicting thermal, as well as mechanical energy liberation during simulated muscle contractions. The model was designed to yield energy (heat and work) rate predictions appropriate for human skeletal muscle contracting at normal body temperature. The basic form of the present model is similar to many previous models of muscle energy expenditure, but parameter values were based almost entirely on mammalian muscle data, with preference given to human data where possible. Nonlinear phenomena associated with submaximal activation were also incorporated. The muscle energy model was evaluated at varying levels of complexity, ranging from simulated contractions of isolated muscle, to simulations of whole body locomotion. In all cases, acceptable agreement was found between simulated and experimental energy liberation. The present model should be useful in future studies of the energetics of human movement using forward dynamic computer simulation.
