在最近的专题文献中，已经建立了许多基于加速度计的能量消耗估计算法和平台，并且每一种算法和平台都与能量消耗测量中的黄金标准，即间接量热法具有很高的相关性。这项研究的目的是实现一组这些算法，在一个通用的数据集上运行它们，并调查与每个算法相关的优点和缺点。这些算法随后被移植到微光设备上，用于实时、移动和非侵入性的能量消耗估计解决方案。在加速度计回归的能量消耗估计和计算机上的参考数据集以及算法的微调实现之间都发现了高度的相关性。
Many accelerometer-based energy expenditure estimation algorithms and platforms have been established in recent topical literature, and each boasts a high correlation against the gold standard in energy expenditure measurement, i.e. indirect calorimetry. The aim of this study was to implement a set of these algorithms, run them all over a common dataset and investigate the strengths and weaknesses associated with each. The algorithms were then ported to a SHIMMER device for a real time, mobile and non-invasive energy expenditure estimation solution. High correlations were found between the accelerometer-regressed energy expenditure estimates and the reference dataset both on a computer and SHIMMER-implementation of the algorithms.
