Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

According to data of the International Diabetes Federation (IDF), diabetes in general affects approximately 415 million people worldwide and this number is still increasing. Cardiovascular diseases, one of the major complications of diabetes, are the leading cause of mortality and morbidity in the diabetic population. One of the cardiovascular complications is diabetic cardiomyopathy, in which structural and functional changes occur in the heart impairing cardiac function.

Exercise training has already proven the benefits on glycemic control in diabetes. This is also the case for the effects on cardiac function. However, as results are conflicting, it remains unclear which elements of exercise training should be focused on. For instance, high-intensity interval training (HIIT) is gaining interest as positive effects are already shown on glycemic control. Therefore, the potential of HIIT to improve cardiac function in diabetes should be investigated. Further on, the effects of exercise training on cardiac function are mainly investigated during rest by the use of transthoracic echocardiography. Therefore, as data are lacking, it remains unclear how the diabetic heart functions during exercise.

The aim of the present study is to investigate the effects of different training modalities (e.g. HIIT) on heart function in diabetes both during rest and during exercise itself. Therefore, cardiac function will be evaluated by the use transthoracic (exercise) echocardiography. This will be combined by the evaluation of several biochemical parameters.

The results will provide more insight in the pathology of diabetic cardiomyopathy as well as the potential of exercise training for this cardiovascular complication. Eventually, this research will contribute to the optimization of exercise programs for patients with diabetes.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

training group 1: HIIT

high-intensity interval exercise training group (T2DM patients)

Group Type ACTIVE_COMPARATOR

high-intensity interval exercise training (HIIT)

Intervention Type OTHER

This program includes 24 weeks of exercise training and is divided in different phases (phase 1: week 1-2, equal to the MIT group, phase 2: week 3-6, 6 bouts of high-intensity exercise, phase 3: week 7-12, 7 bouts of high-intensity exercise, phase 4: week 13-24, 8 bouts of high-intensity exercise). The exercise training program consists of 3 exercise sessions per week (for 6 months).

training group 2: MIT

moderate-intensity exercise training group (T2DM patients)

Group Type ACTIVE_COMPARATOR

moderate-intensity exercise training (MIT)

Intervention Type OTHER

This program includes 24 weeks of exercise training and is not devided in phases. The exercise training program consists of 3 endurance exercise sessions per week (for 6 months). The total exercise volume equals the exercise volume of the HIIT group.

Detraining period

Follow-up: detraining of group 1 and 2 (T2DM patients)
