Study Overview
Brief Summary
Physical activity appears to be a novel and original adjunctive therapeutic approach in the management of patients with schizophrenia. It may help reduce schizophrenic symptoms, act as a pro-cognitive therapy, improve quality of life, and reduce cardiovascular comorbidities. Moreover, some evidence suggests that physical activity practiced in a natural environment has even more positive effects on mental health compared to physical activity carried out indoors or in urban settings. Indeed, greater exposure to greenery is associated with a better perception of general health and with reduced levels of cortisol, anxiety, and depression. No study has yet attempted to examine the impact of physical activity in green (outdoor) spaces compared to indoor physical activity on the negative symptoms of patients suffering from schizophrenia. The aim of this study is therefore to test this hypothesis.

Outcomes
Primary Outcomes
Self-evaluation of negative symptoms (SNS) questionnaire
Time Frame: Weeks 2, 10 and 22
The primary outcome will be the evolution of negative symtoms, assessed using the Self-evaluation of negative symptoms (SNS) questionnaire. The total SNS score ranges from 0 to 40, where higher scores indicate greater severity of negative symptoms.
Secondary Outcomes
- Balance(Weeks 2, 10 and 22.)
- Clinical global Impression (CGI) scale(Weeks 2, 10 and 22)
- Personal and social performance (PSP) scale(Weeks 2, 10 and 22)
- Subjective Scale to Investigate Cognition in Schizophrenia (SSTICS)(Weeks 2, 10 and 22.)
- VO2 max(Weeks 2, 10 and 22.)
- Flexibility(Weeks 2, 10 and 22.)
- Maximum force(Weeks 2, 10 and 22.)
- Spatio-temporal coordination(Weeks 2, 10 and 22.)
- IPAQ questionnaire(Weeks 2, 10 and 22.)
