Coupling of Infant Respiration and Locomotion.

描述（由申请人提供）：这组研究将确定健康婴儿在生命的第一年呼吸是否与运动活动协调。将与成人进行直接比较。将确定哪些活动特别可能显示出协调。这些研究将确定一个节律活动的扰动是否也会引起第二个活动的扰动，如果协调依赖于成熟，这种发展的时间过程也将被调查。最后，将确定早产婴儿的协调性是否正常，以及这组婴儿的协调性如何发展。了解积极的运动如何影响幼儿的呼吸是很重要的。了解这种关系对有呼吸系统疾病风险的婴儿尤为重要。这些研究将为今后将这项工作扩展到有风险的婴儿提供必要的基础工作。

DESCRIPTION (provided by applicant): This group of studies will determine if breathing is coordinated with locomotor activities in healthy young infants during the first year of life. Direct comparisons will be made with adults. Activities will be determined which are especially likely to show coordination. These studies will determine if perturbations to one rhythmic activity will also cause perturbation of the second activity, if the coordination is dependent on maturation, the time course of this development will also be investigated. Finally, it will be determined if the coordination is normal in infants born prematurely, and how this coordination develops in this group of infants. It is important to know how active movements affect breathing in young infants. It is particularly significant to understand this relationship for infants who are at risk for respiratory problems. These studies will provide the ground work necessary for future extension of the work to infants at risk.
