The investigators define the Invisible Preparation (IP) as the set of health behaviors that young athletes implement, on their own, to optimize their health and performances. This includes sleep, nutrition and hydration, physical well-being (injuries prevention) and mental well-being. If some studies have reported a lack of compliance in young athletes regarding sleep and hydration recommendations, the literature is poor in this field.

The CMS (Brest Metropolitan Area Sports Medicine Centre, France) aims at preserving the health of young athletes. Prior to their medical examination, the patients will be asked, all along the year 2024, to fill out a form that question them about their health behaviors in the four areas of the IP.

Under the direction of the Brest University Hospital, PRICELESS (Invisible Preparation of Middle and High School Students in Sports Institutions) study will try, based on their answers, to estimate the proportion of young athletes who declare adopting the health behaviors recommended in the IP.

Inclusion Criteria:

• Middle and High School students
• Being part of a Sports Institution (Club, Sport Section at School, Local Training Institution, or Elite Training Institution)
• Absence of opposition from the patients or their legal representatives

Exclusion Criteria:

• Refusal to participate
• Significant mental or psychological disability, making it impossible to obtain reliable answers
