Spot Reduction in Male Adults
A study testing Abdominal aerobic endurance exercise in people with Healthy, run by Molde University College.
Trial summary
Spot reduction, referring to local body fat reduction, pertains to subcutaneous adipose tissue utilization from specific body parts during exercise. Its existence has been keenly debated, although generally accepted not to occur during exercise. Read more about this study

About this study
Official title: The Assessment of Spot Reduction in Adults Males Following Endurance Training
Spot reduction, referring to local body fat reduction, pertains to subcutaneous adipose tissue utilization from specific body parts during exercise. Its existence has been keenly debated, although generally accepted not to occur during exercise. However, it is based on not only equivocal data - commonly the training protocol typically applied is based on strength rather than endurance training. The investigators sought to test this assumption by utilizing endurance based exercise controlling for energy expenditure and using dual x-ray absorptiometric measures to assess body composition before and after training.

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?
Trunk fat mass change (time frame: Change from pre (baseline) to post test (after 10 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 3 Apr 2023.
