Evaluation of the Effect of Adapted Physical Activity on the Modification of Lipid Metabolism During Chemotherapy for Metastatic COLorectal Cancer

This study will be open on 2 sites (CIC CHU Dijon with inclusion of 18 volunteers and CGFL with inclusion of 36 patients).

The participants will be randomized in 4 differents groups :

• Group 1 (for patients only) : No adapted physical activity teacher arm
• Groupe 2 (for patients only) : Arm intervention with an adapted physical activity teacher - minimum volume of INCa recommendations for adapted physical activity
• Groupe 3 (for patients only) : Arm intervention with an adapted physical activity teacher - maximum volume of INCa recommendations for adapted physical activity
• Groupe 4 (for volunteers only) Each participant in the 4 groups will have to complete questionnaires (quality of life, physical activity and dietary intake) and take 3 blood samples for lipidomic analysis.

For patients in groups 1 to 3, participants will be asked to complete a diary to record their daily physical activity and the duration of that activity.

For groups 2 and 3, in addition to the diary, sessions with adapted physical activity teaching will be organised throughout the study.
