Using a 60-second average of wrist movement data gives a more accurate estimate of calorie burn than using shorter 10- or 30-second averages, when people are walking or running on a treadmill.

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
Whether a 60-second window consistently outperforms shorter windows across devices, populations, and activity types, establishing it as the optimal standard.
A systematic review and meta-analysis of all studies comparing EE prediction accuracy using different window sizes (10s, 30s, 60s, 120s) in wrist-worn accelerometers during walking and running, including at least 25 independent datasets with standardized reporting of RMSE and bias.
Whether using a 60-second window improves adherence to energy balance goals compared to shorter windows in free-living conditions.
A double-blind RCT of 200 adults using wrist devices with identical algorithms but different window sizes (10s vs. 60s), over 12 weeks, with primary outcome of daily energy balance accuracy via doubly labeled water and secondary outcomes of user satisfaction and device compliance.
Whether the 60-second window maintains accuracy across real-world walking and running conditions with variable terrain and pace changes.
A prospective cohort study of 300 adults wearing wrist accelerometers with 10s and 60s window algorithms during daily activities for 4 weeks, with periodic validation against portable calorimetry during structured walking and running bouts.
Whether the 60-second window remains optimal in older adults or individuals with different gait patterns.
A cross-sectional validation study comparing RMSE of EE prediction using 10s, 30s, and 60s windows in 100 adults aged 60–75 during treadmill walking and running, using direct calorimetry as reference.
Whether the 60-second window fails to capture rapid transitions between walking and running in individuals with irregular movement patterns.
A case series reporting EE prediction error and classification lag in 8 individuals with Parkinson’s disease or cerebral palsy during treadmill walking and running using 10s, 30s, and 60s windows.
