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

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

Data reduction of CR metrics via principal component analysis, followed by k-means clustering. 54995.rar

The analysis identified nine distinct clusters among the 54,995 participants, including:

Measures quantity and quality during the sleep period. Chronotype: Measures the timing of wakefulness and sleep. Key Findings and Identified Clusters Timing of the most active 10 hours

Based on the search results, "54,995" refers to the sample size of participants from the UK Biobank cohort study analyzed in a 2026 study regarding accelerometer-derived circadian rhythm profiles.

Likelihood of shifting between activity and rest. Methodology 54995.rar

One cluster characterized by high-intensity physical activity.
