MEASUREMENT OF THE DISTRIBUTION OF MUSCLE OPTICAL PROPERTIES

这个子项目是利用资源的许多研究子项目之一 由NIH/NCRR资助的中心拨款提供。子项目的主要支持 子项目的主要研究者可能是由其他来源提供的， 包括其它NIH来源。 列出的子项目总成本可能 代表子项目使用的中心基础设施的估计数量， NCRR赠款不直接向子项目或子项目工作人员提供资金。 使用近红外光谱（NIRS）的测量在肌肉组织中是丰富的，但很少有研究在正常肌肉组织中的光学特性如何变化。 我们建议研究各种因素如何影响肌肉组织的光学特性： (1)肌肉光学特性如何随年龄、性别和肌肉健康水平而变化？ (2)在不同的时间尺度上（每天，每周），肌肉的光学特性有多大变化？ (3)肌肉光学特性的变化如何表明对运动训练的反应（短期和长期）？

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. Primary support for the subproject and the subproject's principal investigator may have been provided by other sources, including other NIH sources. The Total Cost listed for the subproject likely represents the estimated amount of Center infrastructure utilized by the subproject, not direct funding provided by the NCRR grant to the subproject or subproject staff. Measurements using near infrared spectroscopy (NIRS) are abundant in muscle tissues, yet very little has been studied in terms of how optical properties changes in normal muscle tissues. We propose to study how various factors influence the optical properties of muscle tissues: (1) How do muscle optical properties vary with age, gender, and muscle fitness level? (2) How much do muscle optical properties vary on different timescales (daily, weekly)? (3) How do changes in muscle optical properties indicate response to exercise training (both short term and long term)?
