Impact of a Physical Activity Intervention With Motivational Support From Peers for Prostate Cancer Patients

Despite the recognized benefits of physical activity in tertiary prevention, 60-70% of prostate cancer patients are insufficiently active.Yet 150 minutes of brisk walking per week (new WHO recommendations) is associated with a 29% reduction in cancer mortality and a 57% reduction in recurrence.Increasing patients' adherence to regular physical activity appears to be a new challenge for personalized cancer care.Personalized physical activity programmes (1) at home, (2) supported by health professionals, or (3) by peers have shown the effectiveness of regular physical activity.However, these interventions last less than 6 months and do not allow for long-term sustainability of physical activity.Our study proposes to combine 3 interventions, which aim to initiate and maintain regular physical activity in prostate cancer patients:1-The realization of a personalized and realistic physical activity project via physical activity support devices (sport health centers)2-Coaching by a peer (a patient with the same disease who has reached the WHO recommendations for physical activity), who will provide motivational follow-up3-Support by health professionals (attending physician) through the prescription of physical activity.The feasibility of ACTI-PAIR program has been demonstrated, we now wish to evaluate it effectiveness.
