项目摘要

DESCRIPTION (provided by applicant): CADENCE-Adults is an R01 study that will calibrate cadence (steps/min) and intensity in 260 ambulatory adults, 10 men and 10 women for each 5-year age-group category between 21-85 years, effectively covering the adult lifespan. Cadence is one of the temporal-spatial parameters of gait. Cadence multiplied by stride length equals speed. Capture and expression of objectively monitored physical activity in terms of cadence represents an overlooked opportunity to represent free-living patterns of ambulatory intensity. There is merit in being able to "translate" technological and analytical advances into more accessible terms, especially if public health goals are to be realized. Cadence represents a minimally processed and translatable metric that could be collected and interpreted across objective instruments, including those used in the lab, in the clinic, and in the real world. The primary aim of CADENCE-Adults is to identify objectively observed (video-taped) and manually counted cadence (steps/min) criterion cut points associated with markers of increasing intensity across age groupings. A secondary aim is to compare multiple instruments' abilities to accurately detect criterion values for cadence at different speeds and thus better inform our confidence in comparing this metric across instruments. To achieve these aims, cadence and oxygen uptake data will be collected during a treadmill assessment of incrementally faster paces and also using portable metabolic testing of common free- living activities to test the primary hypothesis: Activity intensity (oxygen uptake) will increase in a linear or nonlinear (curvilinear) fashion as cadence increases such that we will be able to develop statistical models for predicting markers (cut points) of intensity from cadence. We are uniquely positioned at the Pennington Biomedical Research Center to successfully conduct CADENCE-Adults as designed in a 5-year time period. We have conducted pilot testing demonstrating the feasibility of this project, established recruiting methods, and are fully experienced in exercise testing, accelerometry, and management of large complex data sets. We expect that cadence cut points established in CADENCE-Adults will be used both to assess ambulatory intensity, but also to inform program design focused on increasing not only the volume of physical activity (e.g., steps/day) but also its intensity (e.g., cadence) in user-friendly metrics. No similar data exist a this time so the approach described in this application is both innovative and critical to providing a minimally processed and translatable objectively monitored metric with established cut points across the lifespan.

描述（由申请人提供）： CADENCE-Adults 是一项 R01 研究，将校准 260 名可行走的成年人（21-85 岁之间每个 5 岁年龄组类别 10 名男性和 10 名女性）的步频（步数/分钟）和强度，有效覆盖成人寿命。步频是步态的时空参数之一。步频乘以步幅等于速度。以节奏来捕捉和表达客观监测的身体活动代表了一个被忽视的机会来代表自由生活的动态强度模式。能够将技术和分析进步“转化”为更容易理解的术语是有好处的，特别是如果要实现公共卫生目标的话。 Cadence 代表了一种经过最少处理和可翻译的指标，可以跨客观仪器进行收集和解释，包括实验室、诊所和现实世界中使用的仪器。 CADENCE-Adults 的主要目的是确定客观观察（录像）和手动计算的步频（步数/分钟）标准切点，这些切点与各年龄段强度增加的标记相关。第二个目标是比较多种仪器准确检测不同速度下踏频标准值的能力，从而更好地增强我们在跨仪器比较该指标时的信心。为了实现这些目标，将在跑步机评估逐渐加快的配速期间收集步频和摄氧量数据，并使用常见自由活动的便携式代谢测试来测试主要假设：活动强度（摄氧量）将以线性方式增加或非线性（曲线）时尚，随着节奏的增加，这样我们将能够开发统计模型来预测节奏强度的标记（切点）。我们在彭宁顿生物医学研究中心拥有独特的地位，能够在 5 年时间内成功开展设计的 CADENCE-Adults。我们已经进行了试点测试，证明了该项目的可行性，建立了招募方法，并且在运动测试、加速度测量和大型复杂数据集的管理方面拥有丰富的经验。我们预计 CADENCE-Adults 中建立的步频切点将不仅用于评估步行强度，还用于为计划设计提供信息，该计划不仅侧重于增加体力活动量（例如，步数/天），而且还注重增加其强度（例如，节奏）以用户友好的指标。这次不存在类似的数据，因此该应用程序中描述的方法既具有创新性，又对于提供经过最少处理和可翻译的客观监控指标以及在整个生命周期内建立的切点至关重要。
