Randomization
At T1, patients are randomly assigned (in a 1:1 ratio) to one of the two groups, namely either to receive standard oncological care alone (Control Group: CG) or standard care plus an exercise program (Training Group: TG), which starts at the halfway point through the chemotherapy protocol. During the follow-up period (T3-T6), both groups follow standard oncological care without supervised PA. Furthermore, the level of PA, without guidelines, is assessed by a connected watch.
