Study to Determine the Relationship Between Exercise and Hypoglycemia in Children With Type 1 Diabetes
NCT00109434 · View on ClinicalTrials.gov ↗
Study Summary
The main purpose of this study is to find out how often low blood sugar (hypoglycemia) happens during the night after exercise in the late afternoon. The study also will see if there are any factors that can predict if low blood sugar is going to develop. Blood samples will also be drawn to measure two hormones-glucagon and epinephrine (adrenaline)-to see how they are affected by exercise. Glucagon helps to raise the blood sugar when it is low. Epinephrine causes symptoms that make the person aware that the blood sugar is low. From the blood sample, other substances in the blood may also be measured to see how they are affected by exercise. A second purpose of the study is to find out whether exercise affects the accuracy of a continuous glucose sensor (CGMS made by Medtronic Minimed). The study will also look at the accuracy of different home glucose meters.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT00109434
The ClinicalTrials.gov registry entry for NCT00109434 describes a study currently listed as completed. It is categorized as an unspecified phase, 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 50 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Jaeb Center for Health Research, which has 134 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Diabetes Mellitus, Type I appearing as the primary indexed condition, and to 0 interventions. 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: NCT00109434 reports 5 study locations spanning 5 distinct geographic areas — top geographies include California, Colorado, Connecticut. 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.
