The aim of this study to investigate the feasibility in hospital reality, of a group exercise program for oncology patients under active treatment and evaluate its impact on some outcomes considered relevant from both clinical and subjective point of view.

The intervention will consist of EFG sessions lasting 45 minutes each, twice a week for 12 weeks to be carried out in the gym of the Rehabilitation Day Hospital.

Each 45-minute session includes an initial relaxation/stretching phase, simple aerobic exercises, muscle strengthening exercises, balance exercises, and will be led by a physiotherapist. The exercises proposed to the group with ECOG 2 will be less intense and of less difficulty with the aim of adapting the activity to patients with a lower performance status (see appendix 4.5, V2, 07/10/2024). The groups will consist of a minimum of five patients and a maximum of ten. Patients will also be stimulated to perform physical activity at home to a total of 150 minutes per week. Patients will be assessed at baseline (T0), at the end of the intervention (T1,12 weeks) and 6 months after the start of the intervention (T2).
