Sleep Hygiene Strategies Among Track and Field Athletes

Sleep is vital for athletes, supporting both physical recovery and mental performance. Despite this, many athletes sleep less than recommended due to demanding training schedules, competition stress, travel, and lifestyle factors. Poor sleep impairs recovery, increases injury risk, and reduces athletic performance. One way to address this issue is through Sleep Hygiene Strategies (SHS)-a set of behavioral recommendations that help improve sleep quality and duration. This randomized controlled trial aims to explore whether the way SHS are delivered-either through written instructions or via verbal education-affects athletes' sleep behaviors and outcomes. The study involves 66 track and field athletes, both male and female, aged 18-40, who train actively at least 2.5 hours per week. Participants are randomly assigned to one of three groups: (1) a control group with no intervention, (2) a group that receives SHS in a written format, or (3) a group that receives SHS via a 40-minute one-on-one verbal session with a trained sleep and sports science professional. The SHS are general and evidence-informed, focusing on optimizing bedtime routines, limiting electronic use before sleep, adjusting environmental factors like noise and temperature, and managing naps effectively. Each participant has to complete a 10-day baseline sleep monitoring period and a 10-day intervention monitoring period. Sleep is measured using actigraphy (a wrist-worn movement sensor) and self-reported sleep diaries. Additional tools included a training diary and the Sleep Hygiene Index (SHI), a questionnaire is use to assess sleep-related habits.
