Study population: 20 patients with type 1 diabetes (treated with or without insulin pump) will participate in three identical test sessions on an exercise bike. During the three test sessions, patients will be monitored by heartrate, blood glucose (obtained by lancet) and CGM. The participants will also be using a diary for registration of diet as well as exercise during the study.
Who may be able to join
- Type 1 diabetes with a diabetes duration of at least 2 years
- age 18-60 years (inclusive)
- given informed consent
- exercises (at least 30 minutes intentional exercise where participants feel exhausted) one or more times a week
- participants agree to use CGM correctly
Who cannot join
- pregnancy
- exercising at a high level (five or more times a week with high intensity)
- treatment with prednisolone or less than a month ago contestant has been treated with prednisolone
- treatment with beta blockers
- Abuse of alcohol / drugs

Questions about this trial
What is this clinical trial studying?
An observational study of Diabetes Mellitus, Type 1 and Exercise, run by Nordsjaellands Hospital at 1 site in Denmark.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 18 Mar 2019. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Denmark. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Blood glucose response measured with CGM (time frame: 3 identical testing sessions throughout 3 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Mar 2019; AzTrials last refreshed its copy on 7 Nov 2026.
