Interval Training in Adults With Congenital Heart Disease a Randomized Trial

3 maart 2016 bijgewerkt door: Bengt Johansson, Umeå University

Effect of Home Based Interval Training on Exercise Capacity and Quality of Life in Adults With Congenital Heart Disease - a Randomized Controlled Multicenter Trial

Adults with congenital heart disease have various degrees of impaired exercise capacity compared to healthy controls. Impaired exercise capacity makes everyday activities more difficult and demanding. There are few studies on effect of exercise training in adults with congenital heart disease. The hypothesis of this study is that structured home based exercise training will improve exercise capacity and health status in the studied population.

Gedetailleerde beschrijving

The number adults with congenital heart disease is increasing. Thanks to advances in the medical and surgical fields the number of adults with complex congenital heart disease is now higher than the children with corresponding heart disease. Though the long term prognosis is still unknown and continuously changing as new therapeutic options are introduced.

Persons with congenital heart disease have different degrees of impaired exercise capacity compared to healthy controls. Some studies indicate that this population is not sufficiently active to achieve the recommendations for physical activity in preventing acquired heart disease. Physical inactivity is an important risk factor for developing acquired heart disease and other life style diseases as obesity and diabetes. In a population where one or more previous cardiac surgeries are common, the prevention of life style diseases is especially important. Exercise training in heart failure and coronary artery disease is well studied and there are clinical guidelines. Regarding exercise training in adults with congenital heart disease, however,the information is sparse and further studies are needed.

Based on defined inclusion and exclusion criteria adults with complex congenital heart disease will be recruited in the Northern Health Care Region in Sweden and in Gothenburg. Before and after the twelve week intervention period the investigators will collect information about cardiopulmonary exercise capacity, health related quality of life, exercise self-efficacy, anxiety and depression. The patients will be randomized to twelve weeks of home based interval training or to a control group. The randomization ratio will be 2:1 (intervention:control). The control group will be instructed to continue with their habitual physical activities. The home based interval training program will be individualized based on the results of the exercise tests.

The aim of this study is to examine the effect of home based interval training on maximal and submaximal exercise capacity, quality of life, exercise self-efficacy, anxiety and depression.

Deelnemersgroep / Arm
Interventie / Behandeling
Experimenteel: Home based interval training
12 weeks home based interval training
The participant in the intervention group will receive an individualized interval training program. The individualized adjustments in training load will be made from the results of the CPET-incremental and adjustments in training time from the results of the constant work rate 75% of peak work rate (Watt). The training will be home based and performed on a ergometer cycle 3 times a week for twelve weeks. During exercise they will wear a heart rate monitoring watch. The registered heart rate will be transferred to a webpage after the exercise session. Only the physiotherapist and participant have the access to this page. The physiotherapist and participant will have a weekly contact to promote compliance, provide feedback and if necessary adjust the training time or load. Progression in training load and time will be made when necessary to keep a relevant intensity.
Geen tussenkomst: Control group
No structured exercise training.
