Prevalence of Sleep Inadequacy Among Badminton Players: A Systematic Review

TL;DR

This review estimates how often badminton players experience poor sleep and identifies factors that may contribute to it.

Contribution

The study systematically reviews sleep inadequacy prevalence and its associated factors specifically in badminton athletes.

Findings

The prevalence of poor sleep health among badminton players ranges from 28% to 36%.

High training volumes, delayed sleep onset, and academic stress are linked to poor sleep quality.

Prior injuries and training frequency do not significantly affect sleep quality.

Abstract

Sleep quality is a critical determinant of athletic performance and recovery, yet limited research has specifically addressed this issue among badminton players. This systematic review aimed to estimate the prevalence of inadequate sleep and identify associated factors in this athletic population. Following a registered protocol (INPLASY202550010), a comprehensive literature search was conducted using the MEDLINE, Scopus, and DOAJ (Directory of Open Access Journals) databases through April 2025. Eligible studies were those that assessed sleep health using validated tools in badminton athletes. A total of two studies met the inclusion criteria, comprising 165 players. The prevalence of poor sleep health ranged from 28% to 36%. Factors contributing to suboptimal sleep included high weekly training volumes, delayed sleep onset, and academic-related stress. In contrast, prior injuries, number of rest days, and overall training frequency showed no significant associations with sleep quality. These findings suggest that both physical and psychological demands may adversely influence sleep in badminton players. Although the available data are limited, the evidence underscores the importance of addressing sleep health in this population. Further research using standardized methodologies and larger sample sizes is warranted to better characterize sleep patterns and inform targeted interventions that support optimal athlete well-being and performance.
