OptiTrain - Optimal Training Women With Breast Cancer

This study on women with breast cancer during and after chemo- and hormonal therapy compares the effect of different physical training programs on physical and mental well-being and systemic inflammation mechanisms in blood. In a sub-group of participants, mitochondrial biogenesis and function and other molecular processes in skeletal muscle biopsies are studied. The women will be randomly allocated into three different intervention arms, a control arm with usual care and two different training arms. All participants will respond to questionnaires and have blood samples and taken and for a subgroup muscle biopsies before and after the exercise intervention. Participants will be supported to uphold exercise through collaboration with Friskis \& Svettis and followed for 5 years. Some of the women will also be asked to participate in an in depth interview about the experiences of exercise during ongoing treatment. This study will contribute to increased knowledge about the type, intensity and frequency of training that patients with breast cancer benefit most from with regards to impact on physical and mental wellbeing. This knowledge is of great importance since experience shows that patients and relatives often seek information about rehabilitation, self-care and physical activity. The study will also contribute to the improvement of the patients´ quality of life, ability to return to work, and reduce social costs, but above all, increase the possibility for development and implementation of evidence-based rehabilitation of women with breast cancer during and after active treatment.
