Mammals maintain a constant core body temperature by generating heat in resting muscles in response to changes in the environmental temperatures. This project aims to show how the fibre types that make up skeletal muscles regulate heat generation against other muscle function, to maintain core body temperature and the normal movement and posture of the mammal. Project outcomes include defining, for the first time, how heat generation in the muscles of the body is regulated. This should provide critical knowledge of mammalian evolution and ways to manipulate metabolism, which may provide ways to assist with achieving a desired meat quality and yield in beef and other commercially important animals.

哺乳动物通过在休息的肌肉中产生热量来维持恒定的核心体温，以应对环境温度的变化。该项目旨在展示构成骨骼肌的纤维类型如何相对于其他肌肉功能调节热量产生，以保持核心体温以及哺乳动物的正常运动和姿势。项目成果包括首次明确了人体肌肉中的热量产生是如何受到调节的。这应该提供哺乳动物进化的关键知识和控制新陈代谢的方法，这可能提供帮助实现牛肉和其他重要商业动物所需的肉类质量和产量的方法。
