New: Reference values for wrist-worn accelerometer physical activity metrics in England children and adolescents bit.ly/40BUXZw

Do you need to count steps using wrist-worn accelerometer data? Dr. Alex Rowlands and team used GGIR to evaluate and optimize the Verisense Step Count Algorithm! pubmed.ncbi.nlm.nih.gov/36384415/ #steps #cadence #OpenScience #GGIR Dr. Ben Maylor Journal of Sports Sciences

What's GGIR? A solution to generate advanced physical activity and sleep metrics from multiday accelerometer data recordings. Next training in May 2023! Do not miss your seat! accelting.com/ggir-training/ #OpenScience #GGIR

GGIR-derived physical activity metrics were used to demonstrate lack of association between lifestyle physical activity and arrhythmic events in arrhythmogenic cardiomyopathy pubmed.ncbi.nlm.nih.gov/36849235/ #PhysicalActivity #Health #GGIR Alberto Soriano-Maldonado Heart_BMJ

#GGIR version 2.9-0 is now available on CRAN! We have summarised the main updates in a new blog post: accelting.com/updates/ggir-r… #OpenScience

🆕🆕🆕 We developed the 'rawacceleration' application to translate our findings into clinical practice, making these metrics accessible to clinicians and patients. 'rawacceleration' is freely available as an R-package on GitHub. Check it out! github.com/FSchwendinger/…

For those of you who work with .cwa files (Axivity AX3 and AX6 devices): Note that #GGIR has become approximately eight times faster to process these files in the past year. To benefit from these updates, install (or update) R package GGIRread 0.2.7: cran.r-project.org/web/packages/G…

Nearly 10 years after its first release on CRAN with an LGPL software license, #GGIR has become even more re-use friendly by adopting the Apache 2.0 license: accelting.com/updates/apache… Apache - The ASF as this new blog post motivates.

New for R package GGIR users Absolute intensity thresholds for accelerometer-measured PA in adults Compared data from 🇧🇷adults to the pioneering study by Hildebrand, and estimated thresholds using other analytical approaches Open access: doi.org/10.1111/sms.14… Inácio Crochemore-Silva

R package GGIR has been on CRAN for 10 years! 🥳🍾 Read here about the long road that is behind us: accelting.com/updates/10th-a… Thanks to all who have contributed so far! Jairo Hidalgo Migueles, Séverine Sabia, Patrick Bos Netherlands eScience Center @akademienl.social Epi of Ageing MRC Epidemiology Unit ICM Newcastle and many others.

🆕tool: We introduce the 'interpretablePA' R-package. This tool facilitates interpretation of these metrics & offers translation into meaningful outcomes , aiding in both research settings and real-world applications. github.com/FSchwendinger/…🛠️ #interpretablePA #iPAforResearchers

🗓️On November 13, 15, 17 is the new series of online GGIR training sessions! An ideal way to start learning GGIR or to boost your knowledge. This can be complemented with the R essential for GGIR training the week before. To book your place go to: accelting.com/ggir-training/🏃‍♀️🏃‍♂️

#GGIR version 3.0-0 is now available on CRAN! We have summarised the main updates in a new blog post: accelting.com/updates/ggir-r…

Come join our team. Grade 7 Research Associate with expertise in accelerometry. Fixed term 4 year contract. Deadline 17th December.

🆕Coming Soon! Explore the raw data (acceleration signals and various sampling rates) comparability of popular research-grade accelerometers in this new study. Abstract available now, full text coming soon! #Accelerometry #Research #DataAnalysis Annelinde Lettink Teatske Altenburg Jeugd & Gezondheid

"Why does GGIR change between releases?" is a question we often get. You can now find Vincent's answer in this GGIR google group thread: groups.google.com/g/RpackageGGIR…

Excited to use our Activinsights: Activity,Sleep,& Lifestyle Insights GENEActiv accelerometers finally today. we will be using R package GGIR to process the data soon

How comparable are the raw data across accelerometer brands and configurations that we feed into GGIR? And why should we care? Read here about a new study led by Annelinde Lettink in Journal for the Measurement of Physical Behaviour that looked into it: accelting.com/updates/compar…

Grateful to Vincent Van Hees and Jairo Hidalgo Migueles for coming all the way to Ghent University to share their expertise in accelerometer data processing with us! 🙌 #accelerometerdata #expertise #doctoralschools @UGent PA & Health
