There is much to be learnt about how the human body responds to exercise. The capacity to examine how acute and chronic exercise stresses the cardiovascular, respiratory, metabolic, and cognitive systems is a fundamental component of exercise science and kinesiology research and relies heavily on high-quality exercise and metabolic monitoring equipment to ensure accurate and reliable data. This request is for a metabolic cart system, treadmill, and cycle ergometer to fill a critical shortage of research-grade testing equipment in the Department of Human Health and Nutritional Sciences at the University of Guelph. It will support three leading edge NSERC research programs which urgently require the infrastructure to advance their research and avoid delays in HQP training. Immediate access to this equipment is imperative for Dr. Millar's research on the causes of inter-individual variability in neuro-cardiovascular responses to exercise. His work has found a role of absolute contraction force in mediating blood pressure responses to static handgrip exercise, explaining why women have attenuated responses despite contracting at the same relative intensity. Unfortunately, this work has been limited to static handgrip exercise, which has limited translation to daily living. The requested equipment will enable Dr. Millar to gain insights into the causes of neuro-cardiovascular variability during the typical daily activities of walking, running, and cycling. High performance exercise equipment is essential to Dr Burr's research on how different types and volumes of exercise acutely and chronically affect the ability to adapt to cardiorespiratory, muscular, and metabolic stresses. Recent work has identified an important role for blood flow restricted exercise in eliciting cardiometabolic and performance adaptations. To advance this innovative research, Dr. Burr requires state of the art equipment with the ability to carefully titrate and adjust exercise loads to accommodate the abilities and limitations of human participants ranging from sedentary to athletic and young to old. Dr. Vallis's research examines how humans seamlessly integrate concurrent motor and cognitive tasks. Her recent work has shown promising improvements with dual-task training using a walking motor task. The acquisition of a research-grade treadmill with safety harness and cycle ergometer will enable new approaches to examine dual-task training that include higher intensity motor tasks, while the metabolic cart will provide novel physiological information relevant to the design of optimal training protocols to improve dual-task performance. The applicants currently train 28 HQP but all three research programs are significantly hindered by the limited access to existing equipment which provides a lower degree of functionality. The requested equipment will greatly expand our capacity for exercise testing and increase opportunities for HQP to conduct high impact human research.

关于人体对运动的反应，还有很多东西需要了解。研究急性和慢性运动如何对心血管、呼吸、代谢和认知系统造成压力的能力是运动科学和运动机能学研究的基本组成部分，在很大程度上依赖于高质量的运动和代谢监测设备，以确保数据准确可靠。 这项要求是一个代谢推车系统，跑步机和自行车测力计，以填补在人类健康和营养科学系在圭尔夫大学的研究级测试设备的严重短缺。 它将支持三个领先的NSERC研究项目，这些项目迫切需要基础设施来推进其研究，并避免HQP培训的延误。 米勒博士对运动引起的神经-心血管反应个体间差异的原因进行研究时，立即使用这种设备是必不可少的。他的工作发现了绝对收缩力在调节静态握力运动的血压反应中的作用，解释了为什么女性在相同的相对强度下收缩时反应减弱。不幸的是，这项工作一直局限于静态的握力练习，这限制了翻译到日常生活。所要求的设备将使米勒博士能够深入了解步行、跑步和骑自行车等典型日常活动中神经心血管变异性的原因。 高性能的运动设备是必不可少的伯尔博士的研究如何不同类型和量的运动急性和慢性影响的能力，以适应心肺，肌肉和代谢压力。最近的工作已经确定了一个重要的作用，血流限制运动引起心脏代谢和性能的适应。为了推进这项创新研究，Burr博士需要最先进的设备，能够仔细滴定和调整运动负荷，以适应人类参与者的能力和局限性，从久坐到运动，从年轻到老年。 博士瓦利斯的研究考察了人类如何无缝整合并发运动和认知任务。她最近的工作表明，使用行走运动任务的双任务训练有希望取得进步。收购一个研究级跑步机与安全带和自行车测力计将使新的方法来检查双任务训练，包括更高强度的运动任务，而代谢车将提供新的生理信息相关的最佳训练方案的设计，以提高双任务的性能。 申请人目前培训了28名HQP，但所有三个研究项目都受到现有设备的限制，这些设备提供的功能程度较低。所要求的设备将大大扩大我们的运动测试能力，并增加HQP进行高影响力人体研究的机会。
