Acquistion of a High-Speed Video System for Motion Analysis

所要求的经费用于购买一套高速录像系统，用于运动分析。该设备将用于研究脊椎动物和无脊椎动物肌肉骨骼系统的生理学。该设备需要解决的研究问题包括：(1)在正常行为中，什么因素调节骨骼肌运动输出的变化？(2)温度对骨骼肌性能有什么影响？(3)肌肉的效率如何？运动时肌肉做多少功？目前用于研究肌肉骨骼功能的成像技术（主要是传统的视频和拍摄）不能提供足够的能力来研究三维复杂运动，运动图像上模拟数据的叠加，或数字图像的处理和分析。

Funds are requested for the purchase of a high-speed video system for motion analysis. This equipment would be used to study the physiology of the musculoskeletal system in vertebrates and invertebrates. Research questions to be addressed with this equipment include: (1) What factors regulate variation in motor output to skeletal muscle during normal behavior? (2) What is the effect of temperature on skeletal muscle performance? (3) How efficient are muscles, and how much work do they do during movement? Current imaging techniques for the study of musculoskeletal function (primarily conventional video and filming) do not provide adequate capabilities for the study of complex movements in three dimensions, the superposition of analog data on the movement image, or digital image manipulation and analysis.
