Exercise in Prevention of Metabolic Syndrome

Status Completed

Clinical Trial Summary

The primary objective of the study is to compare in a real-world setting the efficacy of traditional training (today's guideline, vigorously or moderate exercise) and amount of aerobic interval training (1-AIT) in reduction of risk factors constituting metabolic syndrome.

The secondary objective is to compare the efficacy of traditional moderate training (today's guideline) and amount of aerobic interval training (1-AIT vs. 4-AIT) in improving aerobic capacity, cardiovascular function, skeletal muscle contractile function, skeletal muscle energy metabolism, left ventricle systolic and diastolic function at rest and right ventricular function.

The investigators hypothesized that aerobic interval training would reverse features of the metabolic syndrome more than traditional training.

Clinical Trial Description

This study describes a randomized multicenter clinical trial designed to test the hypothesis that a 16-week program, with one year follow up of vigorously exercise defined from today's guidelines (performed as 4-AIT (4x4min aerobe interval training)) yields larger beneficial effects in reducing risk factors constituting the metabolic syndrome than continuously moderate intensity exercise (CME) defined from today's guidelines.

Furthermore, the importance of the amount of aerobic interval training remains unclear and it is unknown how little "one can get away with" and still obtain substantial beneficial cardiovascular effects. Therefore, the investigators will also determine whether one bout of aerobe interval training (AIT) - 1-AIT = 1x4min aerobe interval training, can give beneficial effects compared to 4-AIT and CME.

Evaluation criteria are risk factors constituting metabolic syndrome, aerobic capacity measured as peak oxygen uptake and compliance to intervention. Assessments will be made before and after the 16-week program, and at six month, and 1 and 3 years follow-up. According to estimates based on data from previously studies, 3, 4 a total number of 465 patients randomized 1:1:1 to the three interventions gives 80% power to detect an effect of 4-AIT compared to 1-AIT/CME of 51% recovery versus 37% recovery from metabolic syndrome at the 5% significance level. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
