Measures the stability and fragmentation of rest-activity cycles, using metrics such as interdaily stability (IS) and intradaily variability (IV).

Circadian rhythm profiles derived from accelerometer ... - Nature

Four clusters focusing on poor RAR (low activity, late chronotype, or restless sleep). Associated Metrics 54995.rar

Two clusters focusing on robust RAR with opposite sleep profiles (longer/efficient vs. shorter/fragmented).

Covers physical activity (PA) and sedentary behaviour (SB). 54995.rar

The study utilized a comprehensive set of 36 metrics to characterize these profiles, including:

Timing of the most active 10 hours. Cosinor Acrotime: Time of peak activity. 54995.rar

The research involved analyzing 7-day, 24-hour accelerometer data to understand behavioural patterns. The study developed nine unique based on four main dimensions:
