🧐Is excess post-#exercise oxygen consumption following high-intensity exercise a source of EE estimation error for traditional linear-based and more recent #machinelearning #algorithms for the #ActiGraph compared to indirect #calorimetry? Article🔗 doi.org/10.1123/jmpb.2…

🧐 Read about new #harmonization efforts for minutes of moderate-to-vigorous @physicalactivity from wrist-worn ActiGraph and GENEActiv #wearables. 📊 Comparison of a consensus method + several individual #MVPA estimation methods included! 🔗 doi.org/10.1123/jmpb.2… Kimberly Clevenger, PhD, MPH

⏱️Curious about: 1.) The overall magnitude of time drift, 2.) The consistency of time drift between #wearables and over multiple waves of data collection, 3.) The impact of the time drift on time spent physically active in #parks? Read this:🔗doi.org/10.1123/jmpb.2…

💡New research about the fragmentation of children's #play is available now! 🏃Indoor vs. outdoor #MVPA and fragmentation probability are provided. 🔗Read the article here: doi.org/10.1123/jmpb.2… Kimberly Clevenger, PhD, MPH Karin Pfeiffer #healthykids #physicalactivity #research

🚨Just Accepted! 🏃Original research from Arto Pesola and colleagues investigating Fibion ⭐ Decoding Physical Behaviors 😴🪑🚶📊 #accelerometer energy expenditure and activity classification validity in children. 😎Abstract available here, article coming soon!

🤰To investigate associations between 24-hr #activity behavior and #pregnancy outcomes various combinations of activPAL, Actiwatch, & #sleep diary data were integrated to describe 24-hr activity. Parsed groupings were investigated to reduce burden. 🔗 doi.org/10.1123/jmpb.2…

🚛What is the impact of #vehicle vibration on wrist-worn #accelerometers? 🛑Read about research aimed at finding a noise-resistant method of MVPA estimation from the wrist. 🔗doi.org/10.1123/jmpb.2… Stacy Clemes Dr. Ben Maylor Charlotte Edwardson Aron Sherry Yu-Ling, Chen #PublicHealth

🌟Exciting new scoping review from Myles O'Brien and colleagues: Accelerometer Determined Free-Living Sit-to-Stand Velocity: A Scoping Review of Methodological Developments, Participant-Level Factors, and Link to Health Check out the abstract here, full text coming soon!

⏰ Comparison of #activPAL time in bed (TIB) #algorithms to polysomnography (PSG): ☑️overestimated TIB by ~40 minutes ☑️detected earlier TIB start and later TIB end ☑️TIB start and end were within acceptable limits, but TIB agreement was weaker Article🔗doi.org/10.1123/jmpb.2…

Researchers investigated the #ActiGraph ActiLife step algorithm's sensitivity to sampling frequency (Hz). 🔑findings: 1. The #algorithm is sensitive to Hz; 30 Hz is the most accurate setting. 2. MAVM algorithm isn’t affected but is less precise. 🔗doi.org/10.1123/jmpb.2…

📢Just Accepted! In this new original research, authors investigate #PhysicalActivity estimations -- volume and across intensity categories -- from #wearables 🆚 heart rate monitors. 👉Read the abstract here, full text soon!
