Abstract

Promoting healthy aging requires identifying modifiable factors that can preserve physiological regulation. Cardiorespiratory fitness (CRF), a key pillar of healthspan, and Circadian Syndrome (CircS), an emerging marker of systemic dysregulation, are both strongly linked to health outcomes, yet their direct relationship is unknown. This study aimed to investigate the cross-sectional and longitudinal associations between estimated CRF (eCRF) and CircS in two large, distinct aging populations.

Research summary

The paper investigates the relationship between estimated cardiorespiratory fitness and circadian syndrome in aging populations. This research is relevant as it explores modifiable factors that could influence healthspan and physiological regulation, addressing potential root causes of aging.
