Coupling of Infant Respiration and Locomotion

描述(由申请者提供)：这组研究将确定在健康的婴儿出生后的第一年，呼吸与运动活动是否协调。将与成年人进行直接比较。将确定哪些活动特别可能显示出协调。这些研究将确定对一个节奏活动的扰动是否也会导致第二个活动的扰动，如果协调依赖于成熟度，则也将调查这种发展的时间进程。最后，将确定早产儿的协调性是否正常，以及这组婴儿的协调性是如何发展的。了解活跃的运动如何影响婴幼儿的呼吸是很重要的。对于有呼吸问题风险的婴儿来说，了解这种关系尤为重要。这些研究将为今后将这项工作扩展到高危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.
