Daily Activity Patterns Impact Cardiorespiratory Fitness in Older Adults
Updated May 29,2025
Your internal clock considerably influences your daily life,from sleep patterns to metabolic functions.Now, new research from the University of Florida Health suggests that the timing and consistency of daily activity may play a crucial role in cardiorespiratory fitness and walking efficiency, both vital for healthy aging.
The study, funded by the National Institute on Aging (NIA), found that older adults who engaged in earlier and more consistent daily activity exhibited better heart and lung fitness compared to those with later or more irregular schedules. The NIA is part of the National Institutes of Health.
Karyn Esser, professor and chair of the UF College of Medicine’s Department of Physiology and Aging, said that while the benefits of activity are well-known, this study indicates that when you are active also matters. She added that the circadian mechanisms driving daily rhythms are essential for overall well-being.
The research,published in Medicine & Science in Sports and Exercise,involved nearly 800 older adults with an average age of 76. Participants wore wrist devices to monitor their activity for a week and underwent cardiopulmonary exercise testing.
Key findings included that higher-amplitude activity and rest cycles, earlier daily peak activity, and greater consistency in daily activity patterns were all associated with improved cardiorespiratory fitness and walking efficiency. Activity encompassed all daily movement, such as walking, gardening, cleaning, or shopping, not just formal exercise.
“While we’ve long known that being active supports healthy aging, this study reveals that when you’re active may also matter,” said karyn Esser, Ph.D., senior author. “The circadian mechanisms that generate daily rhythms in our system are critically important for our well-being.”
The body’s internal clock aligns physiological functions with the day-night cycle. Disruptions to this rhythm can negatively impact sleep, mood, and physical functioning. Esser noted that while the study suggests a link, it doesn’t prove that following an earlier, consistent schedule will directly improve health and fitness.
Esser believes these findings could lead to personalized medicine approaches, tailoring activity and treatment schedules to an individual’s internal clock, or chronotype.She describes herself as a “lark,” or morning person, while acknowledging that many of her colleagues are “owls” who prefer evenings.
What’s next
Future research will explore whether adjusting activity timing can improve health and if these findings apply to younger populations. Esser emphasized the potential for personalized health strategies based on individual circadian rhythms.
