#ConferenceTime This week, our own Manuel Leitner attended the #CEREPS conference in Münster.

#ConferenceTime @irinatimm.bsky.social has presented our Delphi study at the Conference of the Arbeitsgemeinschaft für Sportpsychologie in Heidelberg last week – running into contributor Dr. Kristina Klier. Key facts: n=99 participants 84% compliance consensus on 24 items in round two #Wearables

Wearable Landscape @wearable-landscape.bsky.social · 15/05/2026

#FactFriday 👉 Did you know? Physical activity, sedentary behaviour, and sleep are mutually exclusive physical behaviours of the same 24-hour day. More time in one behaviour always means less time in another. 💡 Wearable research should focus on the whole 24-h movement behaviour cycle. #Wearables

000

Wearable Landscape @wearable-landscape.bsky.social · 08/05/2026

#FactFriday 👉 Did you know? Wearables can collect millions of data points/day – ~2.6–8.6M at 30–100 Hz, or up to ~25.9M with triaxial sensors. Yet we often reduce this to simple metrics like steps or activity time. 💡 The challenge isn’t collecting data, it’s contextualising it. #Wearables #BigData

000

Wearable Landscape @wearable-landscape.bsky.social · 24/04/2026

#FactFriday 👉 Did you know? Wearable research has shifted from simple cut-point thresholds to machine learning approaches that enable a more nuanced and context-aware analysis of activity patterns. 💬 Are you already using machine learning in your analyses? #Wearables #MachineLearning

#FactFriday ✨ Wearables often perform better in the lab than in real life. Algorithms accuracy can drop substantially in real-world (free-living) conditions — where behavior is more complex and less predictable. 💬 Do you prioritize lab or real-world validation? #Wearables #RealWorldData

Wearable Landscape @wearable-landscape.bsky.social · 03/04/2026

#FactFriday 👉 Did you know? The same wearable device can produce very different results depending on where it’s worn. Placement strongly influences how movement is captured, and thus the interpretation of data. 💬 What’s your preferred placement for your research? #Wearables #Accelerometry #Methods

Wearable Landscape @wearable-landscape.bsky.social · 27/03/2026

#FactFriday 👉 Did you know? There is an uncountable number of wearable devices on the market – but only a fraction are properly validated. Not all data is equal! Quality mattes – validation is key 🗝️ 💬 Do you check validation studies before using a device? #Wearables #Validation

Wearable Landscape @wearable-landscape.bsky.social · 20/03/2026

#FactFriday 👉 Did you know? Accelerometers have been used in research since the 80s/90s — long before fitness trackers. The earliest pedometers date back all the way to the late 19th century. ⏱️ They laid the foundation for today’s wearable-based activity measurement. #Wearables #PhysicalActivity
