Sponsor's own description

Background and Rationale Elite athletes frequently experience sleep disturbances due to factors like irregular schedules, travel, and pre-competition stress. Despite the critical role of sleep in physical recovery and mental health, many athletes fail to meet sleep quality recommendations. While sleep interventions have shown promise in improving sleep outcomes, their effects on mental health-especially in athlete populations-remain underexplored. This study investigates the impact of a 4-week app-based sleep intervention, preceded by a workshop, on both sleep and mental health outcomes in Swiss elite athletes.

Objective To evaluate whether a brief, structured sleep intervention improves sleep quality and mental health in elite athletes and to identify perceived facilitators and barriers to intervention success.

Design A single-center, one-arm pre-post intervention study with four time points (baseline, pre-intervention, post-intervention, and 2-month follow-up). No control group is used due to practical constraints.

Participants 16 elite athletes (sport soldiers) enrolled in the Swiss recruit school. All participants are adults and proficient in German.

Intervention

A one-hour sleep workshop covering the importance of sleep and motivation-setting.

A four-week app-based program ("7-Schläfer") with seven audio modules (approx. 30 minutes each), completed flexibly by participants.

Outcomes

Primary outcomes include:

Sleep quality and disturbances

Mental health (depression, anxiety, well-being)

Data will be collected via REDCap using validated questionnaires. After the intervention, individual interviews will gather qualitative feedback.

Analysis Quantitative data will be analyzed using repeated measures ANOVA. Focus group data will be analyzed thematically.

Significance The study aims to provide practical, scalable insights into how sleep-focused interventions can improve athlete well-being and inform recommendations for sport organizations.
