Study Arms (2)
Control
NO INTERVENTIONStudy participants are instructed regarding a healthy diet according to the recommendations of the German Nutrition Society (DGE) and are informed about positive effects of physical activity on incidence and prognosis of breast cancer
Intervention
EXPERIMENTALStructured exercise training plus mediterranean diet: Study participants receive a lifestyle intervention of 12 months duration (3 months intensive intervention plus 9 months maintenance using monthly contacts and meetings). The intervention comprises a structured intensified training based on the results of physical performance diagnostics and a nutrition program based on a mediterranean diet.
