RESUMO
INTRODUCTION: Uptake of sufficient physical activity before and after radical cystectomy is important to improve physical and psychosocial outcomes in bladder cancer (BC) patients. METHODS: In this paper, we describe the development of an evidence-based and theory-informed intervention, guided by the steps of the Intervention Mapping approach, to promote physical activity before and after radical cystectomy in patients with BC. RESULTS: The intervention is a home-based physical activity program. The preoperative timeframe of the intervention is 4 or 12 weeks, depending on administration of neoadjuvant chemotherapy. Postoperatively, the intervention will last for 12 weeks. The intervention consists of a digital oncological platform (DOP), several consultations with healthcare professionals, personal booklet and follow-up phone calls. DOP includes information, diaries, visual representation of progress, mailbox, videos of peers and treating physician explaining the benefits of physical activity, photo material of exercises and a walking program with an activity tracker. Individual goals will be set and will be self-monitored by the patient through DOP. Patients will receive alerts and regular feedback. CONCLUSIONS: Intervention Mapping ensures transparency of all intervention components and offers a useful approach for the development of behaviour change interventions for cancer patients and for translation of theories into practice.

The aim of this study was to analyse muscle activity and subjectively perceived exertion [rating of perceived exertion (RPE)] during whole-body vibration (WBV) in breast cancer survivors. Twenty breast cancer survivors and 20 healthy controls performed isometric squats on a vibration platform. RPE and muscle activity (surface electromyography) of the rectus femoris, vastus medialis, biceps femoris, tibialis anterior and gastrocnemius were recorded under the following conditions: nonvibration (0 Hz) and vibration (20-30-40-50 Hz) conditions. No significant differences were found between groups with regard to muscle activity (P=0.471) and RPE (P=0.629). Only for vastus medialis was muscle activity higher at 20 and 30 Hz compared with 40 and 50 Hz (P<0.05). RPE increased with increasing vibration frequency; however, no difference was found between 20 and 30 Hz (P=0.088). WBV at 20 and 30 Hz revealed lower subjectively perceived exertion and the highest muscle activity and therefore provide the optimal modalities for WBV in breast cancer survivors.
