简要总结
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.
详细描述
- Background and Rationale Elite athletes often suffer from sleep disturbances due to high training loads, frequent travel, jet lag, pre-competition stress, and irregular routines. Poor sleep negatively affects cognitive function, immune response, recovery, and overall performance. It is also strongly associated with mental health challenges including anxiety, depression, and psychological distress.
Although interventions such as sleep hygiene education and sleep extension strategies show promise in improving subjective sleep quality, there is limited evidence on their long-term effectiveness or impact on mental health in elite athlete populations. Moreover, few studies examine what elements of sleep interventions athletes perceive as most helpful or what barriers they face.
This study seeks to close these gaps by evaluating the short- and long-term effects of a structured sleep intervention on sleep quality and mental health in elite Swiss athletes, with additional qualitative data on user experience. 2. Study Objectives Primary Objective To determine whether a 4-week sleep intervention improves sleep quality and mental health (depression, anxiety, and well-being) in elite athletes.
Hypotheses
The intervention will reduce sleep disturbances and improve sleep quality.

结局指标
主要结局
Sleep problems
时间窗: The ISI was administered at four time points: (1) baseline, (2) pre-intervention (4 weeks later, immediately before intervention), (3) post-intervention (6 weeks after pre-intervention), and (4) follow-up (2 months after post-intervention).
The Insomnia Severity Index (ISI, Gerber et al., 2016) was used to assess the severity of sleep problems. The ISI consists of seven items, evaluating difficulties with falling asleep, staying asleep, subjective sleep quality, the impact of sleep disturbances on daily life, and worries about sleep problems in the previous two weeks. Participants rated each item on a 5-point scale ranging from 0 (not at all) to 4 (very much). A total sleep problem score was calculated by summing all item responses. Higher values indicate more sleep problems.
次要结局
- Depression(The PHQ-9 was administered at four time points: (1) baseline, (2) pre-intervention (4 weeks later, immediately before intervention), (3) post-intervention (6 weeks after pre-intervention), and (4) follow-up (2 months after post-intervention).)
- Anxiety(The GAD-7 was administered at four time points: (1) baseline, (2) pre-intervention (4 weeks later, immediately before intervention), (3) post-intervention (6 weeks after pre-intervention), and (4) follow-up (2 months after post-intervention).)
- Well-being(The MHC-SF was administered at four time points: (1) baseline, (2) pre-intervention (4 weeks later, immediately before intervention), (3) post-intervention (6 weeks after pre-intervention), and (4) follow-up (2 months after post-intervention).)
