Coupling of Infant Respiration and Locomotion.

描述（由申请人提供）：这组研究将确定健康幼儿在生命的第一年内呼吸是否与运动活动协调。将与成人进行直接比较。将确定特别有可能显示协调的活动。这些研究将确定对一种节律活动的扰动是否也会引起第二种活动的扰动，如果协调依赖于成熟，则还将研究这种发展的时间过程。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如何发展。了解主动运动如何影响幼儿的呼吸是很重要的。对于有呼吸系统疾病风险的婴儿来说，了解这种关系尤其重要。这些研究将为将来将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.
