Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Musculoskeletal complaints (assessed by the modified version of the BPI) at 4 months, existing of 3 domains: worst pain, pain severity and pain interference. All three domain scores will be primary outcomes which will be tested sequentially to preserve an Alpha of 0.05. | — |

| Measure | Time frame |
|---|---|
| Secondary endpoints (assessed at 4 months, unless otherwise stated) • Lower extremity joint complaints (WOMAC) • Upper extremity musculoskeletal complaints (DASH) • Menopausal symptoms (FACT-ES) • Fatigue (MFI) • Sleep (PSQI) • Quality of Life (EORTC-QLQ-C30;QLQ/BR45) • Anxiety and depression (HADS) • Cognitive problems (online cognitive test battery, at home: Amsterdam Cognition Scan) and self-reported (FACT-COG) • Compliance with endocrine treatment • Use of pain medication - Pain response (composite measure of the BPI and use of pain medication) • Physical fitness/strength (hand grip strength test/leg press/plank position holding test/steep ramp test) - Balance (Short-Form Fullerton Advanced Balance (FAB) scale) • Habitual physical activity (SQUASH) • Blood markers (i.e., inflammatory markers) • Vital signs and anthropometrics (blood pressure and anthropometrics) • Safety : (serious) adverse events during the study | — |
