Brief summary: Depression is a major public health issue due to its frequency (prevalence of 7.5% in adults), its difficulties in therapeutic management (ineffective in 30% of cases and poor compliance) and its societal cost (170 billion euros per year). The most frequent clinical expression is a characterized depressive episode.

Physical activity, through better management of emotions and stress, has been proposed as a complementary therapeutic approach in depression. Studies have shown a decrease in depressive symptoms during a sports program of at least 2 weeks in addition to pharmacological treatment. Similarly, mindfulness meditation, because it reduces ruminations, could also improve the therapeutic management of depression. More recently, virtual reality (VR) exposure therapy has also been proposed in the treatment of anxiety and depression, with a benefit of multisensory stimulation induced by a virtual environment in cognitive and sensory-motor rehabilitation and emotion regulation. However, these therapeutic strategies, in addition to pharmacological treatments, have limits. There is thus a real challenge in designing innovative therapeutic programs for the treatment of depression that encourage motivated practice. A sports activity coupled with immersion in VR could combine the benefits of each of these treatments. With the emergence of new immersive technologies, VR allows the recreation of sensory experiences in an environment close to the ecological context. The use of physical activity on an indoor rower or other sensor-equipped device could thus intensify the psychological benefits of exercise and improve compliance. However, there is a lack of clinical evidence to recommend this coupled therapeutic approach in the additional treatment of depression. This approach is part of the embodied virtual medicine road map.

Furthermore, a better understanding of the biological, metabolomic, and cerebral mechanisms underlying this approach could improve its effectiveness. It would make it possible to propose and evaluate biomarkers for therapeutic and prognostic monitoring of depression. In particular, progress in the field of the "-omics" family includes new tools with great potential. This is more specifically the case of metabolomics. The analysis of metabolites present in the organism or released with natural secretions would allow to constitute a metabolomic signature evolving during the treatment. The interest in characterizing metabolomic biomarkers is an interesting avenue to meet the need to establish a biological diagnosis with quantified values, for better objectivity and follow-up. Functional imaging could also be used to highlight regional activity or connectivity anomalies and markers of response to therapy in relation to biology.

The aim of this work is to determine the clinical impact of physical exercise in VR on a depressive state, and to study in biology, metabolomics and neuroimaging the functional substrates of such a practice in order to understand the mechanisms involved and to propose ways to improve the management of depression.
