Validation of Cut-Points for Evaluating the Intensity of Physical Activity with Accelerometry-Based Mean Amplitude Deviation (MAD)
PURPOSE Our recent study of three accelerometer brands in various ambulatory activities showed that the mean amplitude deviation (MAD) of the resultant acceleration signal performed best in separating different intensity levels and provided excellent agreement between the three devices. The objective of this study was to derive a regression model that estimates oxygen consumption (VO2) from MAD...
متن کاملIntensity Thresholds on Raw Acceleration Data: Euclidean Norm Minus One (ENMO) and Mean Amplitude Deviation (MAD) Approaches
OBJECTIVES (1) To develop and internally-validate Euclidean Norm Minus One (ENMO) and Mean Amplitude Deviation (MAD) thresholds for separating sedentary behaviours from common light-intensity physical activities using raw acceleration data collected from both hip- and wrist-worn tri-axial accelerometers; and (2) to compare and evaluate the performances between the ENMO and MAD metrics. METHOD...
متن کاملSampling, noise-reduction and amplitude estimation issues in surface electromyography.
This paper reviews data acquisition and signal processing issues relative to producing an amplitude estimate of surface EMG. The paper covers two principle areas. First, methods for reducing noise, artefact and interference in recorded EMG are described. Wherever possible noise should be reduced at the source via appropriate skin preparation, and the use of well designed active electrodes and s...
متن کاملAmplitude and Phase Deviation in the Nlc Detuned Structure
The 1.8m accelerating structure for the NLC consists of 204 individual cells and two coupling cells each differing in phase from their full cell nearest neighbor by 2x/3 radians. In order to avoid the deleterious effects of beam breakup it is required to minimize the trailing wake field left behind by electron beam bunch trains traversing the iris-loaded slow-wave structure. This is effected by...
متن کاملAmplitude and amplitude variation of emotional speech
The present study introduces a recording technique to maintain all dynamic information of even full-blown emotional speech, and investigates the effect of emotion class, speaker, and sentence type on the amplitude of speech. The results show that the factors emotion class and speaker are highly significant and that the former explains half of the variance while the latter explains only one nint...
