Trust is the willingness of people to cooperate. Although much research has been conducted on physical activity, little research has explored trust in institutions regarding environmental and physical activity recommendations. This study aims to assess the level of trust in sources of physical activity recommendations as well as to determine the factors that may influence trust in sources of physical activity recommendations, such as environmental, sociodemographic, or lifestyle factors.

Cross-sectional observational study using an online self-administered questionnaire (RedCAP). Flyers with the QR code/link to the questionnaire will be distributed 1) electronically by email via institutional mailing lists of employees/agents, social networks, blogs, internet advertisements, etc. and 2) in paper format in all locations likely to increase the number of respondents (sports facilities, public or private establishments, supermarkets and places of consumption, etc.). The questionnaire is quick and easy to complete (5 to 10 minutes), and participation is voluntary. The study is completely anonymous. No identifying data will be collected (no email address, no date of birth, etc.).

Inclusion Criteria:

• Anyone willing to participate.

Exclusion Criteria:

• Refusal to participate in the study is equivalent to not completing the self-administered questionnaire.
