Sleep Restriction and Postprandial Lipemia
NCT05713370 · View on ClinicalTrials.gov ↗
Study Summary
Sleep restriction increases overnight and early morning non-esterified fatty acids (NEFA) levels, which are correlated with whole-body decreases in insulin sensitivity, consistent with the observed impairment of intracellular insulin signaling. Adipose tissue biopsies from sleep restricted subjects that are insulin stimulated have reduced phosphorylation of protein kinase B (pAKT). This protein is involved in suppression of intracellular lipolysis and NEFA release. Aerobic exercise has beneficial effects on postprandial lipemia and insulinemia in normal-weight and obese individuals. Acute moderate-intensity aerobic exercise (30-90 min) performed 12-18 h before an oral fat tolerance test or mixed meal test reduces postprandial triglycerides (TG) and insulin concentrations. This response is largely dependent upon the exercise-induced energy deficit as the response is abolished when the calories expended during exercise are replaced. However, it is not known if sleep restriction will interfere with the beneficial effects of prior exercise on postprandial lipemia. The aim of this project is to investigate if sleep restriction negates the positive effect that exercise has on postprandial lipemia. It is hypothesized that sleep restriction will negate the beneficial effects of prior exercise on postprandial lipemia. Additionally sleep restriction will result in a worsening of the lipid profile compared to no exercise. For the proposed study, the investigators will use a repeated measures analysis of variance (ANOVA) (4 study conditions (no exercise+ sleep restriction, no exercise+normal sleep, exercise+normal sleep, exercise+sleep restriction) x time will be used to analyze changes in NEFA and TG concentrations while a one way ANOVA will be used to analyze area under the curve of the NEFA and TG concentrations.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT05713370
The ClinicalTrials.gov registry entry for NCT05713370 describes a study currently listed as completed. It is categorized as NA, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 10 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is University of Missouri-Columbia, which has 275 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 2 conditions, with Obesity appearing as the primary indexed condition, and to 1 intervention — of which high fat meal is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT05713370 reports 2 study locations spanning 1 distinct geographic area — top geographies include Missouri. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
