This research examines the influence of temperature on the speed and force of muscle contraction. Most biological rate processes are strongly influenced by temperature and are inhibited at low body temperatures. This research will examine the extent to which locomotor and feeding ability can proceed and be effective over a wide range of temperatures. The extend to which these functions are directly limited by muscle contractile kinetics will be determined. "Cold-blooded" vertebrates (those which vary temperature with environments) are used as model systems because of the ease with which their body temperatures can be manipulated.

这项研究考察了温度对肌肉收缩速度和力量的影响。大多数生物速率过程受到温度的强烈影响，在较低的体温下会受到抑制。这项研究将检查运动和摄食能力在广泛的温度范围内能够进行和有效的程度。这些功能在多大程度上直接受到肌肉收缩动力学的限制将被确定。“冷血”脊椎动物(那些温度随环境变化的脊椎动物)被用作模型系统，因为它们的体温很容易被操纵。
