🔍 How consistent are activPAL algorithm updates?

A new study compared CREA vs. GHLA algorithms w/ 6,038 days & 350 adults:
✅ 24 of 29 posture/activity metrics were equivalent within 3%
📈 Correlations: r = .97–1.00
Great news for for cross-study comparisons!

🏃‍♂️5 of 21 algorithms for wrist-worn sensors estimated #SedentaryTime within 10% of a gold-standard reference in free-living adults.

#ML & cut-point methods both showed promise—real-world testing matters!

🆕 ActiWearCheck, a new Python tool, flags valid Fitbit wear days using only energy expenditure data—no heart rate needed!

Across 3,339 days and 72 participants, it boosted step & energy expenditure estimates by 12% & 6%.

🏃‍♂️📉Measuring #PhysicalActivity in older adults with #WearableTech? It's not one-size-fits-all.

In a new JMPB study, researchers found heart rate and accelerometry don’t always agree-especially at low & vigorous intensities.

🆕24-hr #PhysicalActivity cycle

Move 4 and #activPAL monitors were compared over 24 hrs➡️

✅ Strong agreement for steps, METs & activity categories
✅ Monitors equivalent for MVPA, sedentary time & steps
❌ Differences found for light activity, #sleep and METs
