This proposal is requesting the SensorMedics Vmax 29 Encore Cardiopulmonary System.  This specialized equipment is used in humans to measure how much oxygen and carbon dioxide is breathed in and out; this can be done at rest or during exercise.  The equipment is specialized because it gives this information for each breath that is taken whereas similar systems need to collect and average several breaths to provide accurate results.  The requested equipment is very sensitive so it can be used to measure very rapid changes in breathing and these changes provide very valuable information on how the body responds to changes in its need to use energy.  As a new investigator building a research program, my work focuses on children's responses to exercise.  The main objective of this work is to understand what makes physical activity good for children's health.  The requested equipment is essential to my work as it provides a non-invasive method to measure many aspects of a child's response to exercise and how growth affects these responses.  With this equipment, I can a) measure fitness levels by directly measuring how much oxygen can be consumed during exercise; b) estimate what energy sources muscles use during exercise by measuring the relationship between oxygen and carbon dioxide; and c) gain some insight into how much blood is being delivered to the working muscle by knowing how quickly oxygen is being used by the body.  The ability to understand all of these processes in children who are growing provides an excellent way to learn what factors help control these responses.  This information will be very useful for researchers in other areas interested in how regular physical activity translates into health.  The requested equipment will create numerous possibilities to work together with other experts in the field and provide an essential tool for training of my students and visiting scholars who are currently restricted in their access to similar equipment.  Our laboratory is one of only a few in the world devoted to the study of children and exercise and this equipment will keep us at the leading edge of exciting new discoveries.

该提案要求使用SensorMedics Vmax 29 Encore Cardiovascular System。该专用设备用于测量人类吸入和呼出的氧气和二氧化碳量;这可以在休息时或运动时完成。2该设备是专门的，因为它为每次呼吸提供这种信息，而类似的系统需要收集和平均几次呼吸以提供准确的结果。所要求的设备是非常敏感的，所以它可以用来测量呼吸的非常快速的变化，这些变化提供了非常有价值的信息，关于身体如何响应其需要使用能量的变化。作为一个新的研究人员建立一个研究计划，我的工作集中在儿童对运动的反应。2这项工作的主要目标是了解什么使体育活动对儿童的健康有益。所要求的设备对我的工作至关重要，因为它提供了一种非侵入性的方法来测量儿童对运动的反应以及成长如何影响这些反应的许多方面。有了这种设备，我可以a）通过直接测量运动期间可以消耗多少氧气来测量健康水平; B）通过测量氧气和二氧化碳之间的关系来估计肌肉在运动期间使用的能量来源;以及c）通过了解身体使用氧气的速度，可以深入了解有多少血液被输送到工作肌肉。了解正在成长的儿童的所有这些过程的能力，为了解哪些因素有助于控制这些反应提供了一个很好的方法。这些信息对于其他领域的研究人员非常有用，他们对定期的身体活动如何转化为健康。所要求的设备将创造许多可能性，与该领域的其他专家一起工作，并为培训我的学生和访问学者提供必要的工具，他们目前在获得类似设备方面受到限制。我们的实验室是世界上仅有的几个致力于儿童和运动研究的实验室之一，该设备将使我们处于令人兴奋的新的前沿。发现。
