Tissue Artifact Removal from Respiratory Signals Based on Empirical Mode Decomposition

TL;DR: An algorithm based on the mutual information and power criteria was devised to automatically select appropriate intrinsic mode functions for tissue artifact removal and respiratory signal reconstruction and comparison with low-pass filtering that has been conventionally applied confirmed the effectiveness of the technique in tissue artifacts removal.
Journal ArticleDOI

Energy expenditure of selected household activities during pregnancy.

TL;DR: This study measures the metabolic cost of four commonly reported household activities (window washing, dusting, vacuuming, and laundry) during each trimester of pregnancy to assess if energy costs for these activities changed across trimesters, and compare the observed values to those presented in the compendium.
Journal ArticleDOI

Submaximal exercise quantified as percent of normoxic and hyperoxic maximum oxygen uptakes.

TL;DR: Maximum oxygen uptake was measured in six college-aged males under normoxic (NVO2max) and hyperoxic (HVO2max; 70% oxygen) conditions and no significant changes in VE, epinephrine, norepinephrine, or blood lactate were observed when hyperoxia and normoxia were compared.
Journal ArticleDOI

Estimating Sedentary Time from a Hip- and Wrist-Worn Accelerometer

TL;DR: Accurate group-level estimates of SB from a hip-worn AG can be achieved using either simpler count-based approaches (CPM100, CPM150) or machine learning models (Soj1x, Soj3x).
Journal ArticleDOI

Blood Lactate Responses to Exercise in Children: Part 2. Lactate Threshold

TL;DR: An analysis is presented comparing children to adults regarding responses to submaximal exercise, and the lactate threshold as a percentage of VO2max, and possible explanations for lower blood lactate concentrations during sub maximal exercise in children are considered.
