Inclusion Criteria

Participants must be between 18-40 years old, and actively competing in a team-sport and registered with a club at a minimum community level. Participants will be recruited from a range of invasion team-sports (e.g., football, rugby, soccer) with participants to be completing structured exercise at least three times per week for a minimum total of five hours per week to meet trained athlete” guidelines. Further, participants will be screened using the Athlete Sleep Screening Questionnaire and Pittsburgh Sleep Quality Index, and those with a sleep difficulty score equal to or greater than 5, global PSQI score >5 and a sleep onset latency >15 minutes will be eligible. These scores coincide with equal to or greater than mild sleep difficulty and poor-quality sleep, which are the targeted participants for this study.
