children in need of early PA intervention may not be identified as habitually inactive using wearable sensors due to insufficient device wear time. To our knowledge, brief accelerometer data samples (∼15 minutes) have not been explored as a means by which to identify children at risk of insufficient daily

aforementioned studies comparing BMC from DXA and BIA used small samples and correlational analyses, so more definitive conclusions about the efficacy of using BIA to estimate BMC, and the extent of bias between BMC values from DXA and BIA, remain unknown. Accordingly, the purpose of this study was to validate

time, and some office-specific activities (such as sitting); however, further evidence is necessary to inform the collection of such measures in the field. Firstly, validity has been established only when using the shortest sampling interval (i.e., the 10-s proximity setting; Clark et al., 2018 ). Use

). However, at least for devices producing a moderate level of difficulty (e.g., foam mats, slowly moving platforms, etc.), most of the available literature reports a corresponding loss of complexity in center of pressure (COP) and muscle dynamics. For example, by means of sample entropy (SEn) and largest

 g). Low-range sensors may not capture signals necessary to optimally characterize moderate to vigorous activities. Other factors include the resolution of the sensor (e.g., 8 vs. 12-bit) and sampling rate (e.g., 10 to 100 Hz). Inter-device output heterogeneity may increase device-dependency, impact

Nonlinear dynamic measures such as time-to-boundary (TTB) and sample entropy (SampEn) analysis, which quantify the structure or organization of the postural control variability ( Glass, Ross, Arnold, & Rhea, 2014 ; Hertel & Olmsted-Kramer, 2007
