Official title
Mechanisms for Sleep/Circadian Disruption-Induced Impairments in Bone Formation
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This is a small intervention study with healthy males aged 20-65 years old who habitually sleep 7-9 hours/night.This study investigates if and how sleep restriction, independent of circadian misalignment (e.g. shift work, jet lag), induces a decrease in the bone formation marker Procollagen I Intact N-Terminal Propeptide (PINP). The specific aim is to evaluate the mechanistic underpinnings for the relationship between sleep restriction and suppression of bone formation. The study will enroll 12 healthy male participants and have a two-week intervention after enrollment.
