About this study
Official title: The Effect of Aerobic Interval Training on Cardiac Function in Patients With Diabetes Mellitus Type 2 and Diastolic Dysfunction
The aim of the study is to compare the effects of aerobic interval training and the IDF recommendations on physical activity on cardiac function and CV risk factors in patients with diabetes. The hypothesis is that AIT more than MCT, will improve myocardial dysfunction in patients with subclinical LV disease, improve both endothelial function and VO2max and thus reducing CV risk factors and CV disease. HbA1c will be more stable.
The aims of this study are to address the exercise prescription recommendations for patients with (T2DM) who have subclinical heart disease. The prescription recommendations will be assessed by randomising T2DM patients with subclinical heart disease to one of the following 2 groups for 3 months followed by a 9 month home-based program:

Moderate Intensity Exercise Group (ME). Home exercise equivalent to the present exercise recommendations of the International Diabetes Federation.
Aerobic interval training (AIT). Exercise equivalent to the current guidelines achieved through high-intensity interval training.
Read the detailed description
The investigators primary hypotheses are that in patients with type 2 diabetes and subclinical heart disease:
Moderate Intensity Exercise will:
Not significantly improve myocardial function compared to controls,
Despite significant improvement (compared to controls) in:
Glycaemic control (HbA1c) Cardiorespiratory fitness (VO2max) Body composition (DXA)
Aerobic Interval Training Group will:
Significantly improve myocardial function compared to controls,
Significantly improve (compared to moderate intensity exercise group):
Glycaemic control (HbA1c) Cardiorespiratory fitness (VO2max) Body composition (DXA)

ExerciseOther
- Moderate Intensity Exercise Group (ME). Exercise equivalent to the current exercise guidelines. In total 210 minutes per week of continuous moderate intensity (70% HRmax) exercise. Home based training.
- Aerobic interval training (AIT). Exercise equivalent to the current guidelines achieved through high-intensity interval training.The exercise starts with warming-up for 10-min at 70% of HRmax before performing 4x4min intervals at 90-95% of HRmax, with 3-min active recovery at 70% of HRmax between each interval, and a 5-min cool-down period, giving a total of 40-min.

Questions about this trial
What is this clinical trial studying?
A study testing Exercise in people with Diabetes Type 2, run by Norwegian University of Science and Technology at 1 site in Norway.
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 1 inclusion and 14 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 5 Jan 2018. 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 Norway. 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?
Early diastolic tissue velocity (e') (time frame: 3 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01206725, which also lists 4 linked publications.
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 5 Jan 2018.
