Chronotype and physical activity: An objective one-week assessment of young adults in a controlled home setting

No significant differences in average physical activity levels were found among intermediate, morning, and evening chronotypes.

• Chronotype may influence physical activity levels, though results have been inconsistent in previous studies.
• Morning types are generally thought to have higher physical activity levels than other chronotypes.
• This analysis utilized actigraphy data collected during well-rested sleep weeks.
• Data were recorded every 30 seconds over 7 days and all waking hours.
• The findings suggest that further investigation is needed to clarify the relationship between chronotype and physical activity.
