The Relationship Between Sleep Quality and Performance During the Competition in Professional Badminton Players

Abstract

Sleep is crucial for athletic performance, as insufficient rest impairs cognitive function, psychomotor skills, and reaction time, all critical during competition. Research specifically on this relationship in badminton is limited. Therefore, this study investigated the relationship between sleep quality, gender differences, and tournament performance in professional badminton players. The sample included 78 professional badminton players (39 male, 39 female), aged 15–33. Sleep quality over the past month was assessed using the Pittsburgh Sleep Quality Index (PSQI). The tournament results and world rankings were taken from the Badminton World Federation Webpage Non-parametric tests (Wilcoxon Signed-Rank Test) were used for gender comparisons due to non-normal data distribution, and Spearman Correlation Analysis was applied for variable relationships. The mean PSQI Total Score for all athletes was 5.97 ± 2.74, which is close to the threshold (>6) indicating ‘poor sleep quality’. Although there was no significant difference in the Total PSQI Score between genders (p = 0.752), female athletes showed a significantly higher score in the Habitual Sleep Efficiency subscale (0.59 ± 1.09) compared to males (0.17 ± 0.45) (p = 0.036). Furthermore, a negative, significant correlation was found between the PSQI Daytime Dysfunction subcomponent and tournament results specifically in male participants (p = 0.015, r = -0.388). The international professional badminton players tend toward impaired overall sleep quality, with female athletes exhibiting significantly lower sleep efficiency than their male counterparts.

Profesyonel Badmintoncularda Uyku Kalitesinin Müsabaka Performansına Etkisi

Abstract

Uyku, yetersiz dinlenmenin bilişsel işlevi, psikomotor becerileri ve tepki süresini bozması nedeniyle atletik performans için hayati öneme sahiptir; bu unsurların tamamı müsabaka sırasında kritik öneme sahiptir. Bu ilişkinin badminton özelindeki araştırmaları sınırlıdır. Bu nedenle, bu çalışma profesyonel badminton oyuncularında uyku kalitesi, cinsiyet farklılıkları ve turnuva performansı arasındaki ilişkiyi araştırmıştır. Örneklem, 15-33 yaş aralığında 78 profesyonel badminton oyuncusundan (39 erkek, 39 kadın) oluşmuştur. Geçen ayki uyku kalitesi, Pittsburgh Uyku Kalitesi İndeksi (PSQI) kullanılarak değerlendirilmiştir. Turnuva sonuçları ve dünya sıralamaları Badminton Dünya Federasyonu Web Sayfasından alınmıştır. Verilerin normal dağılım göstermemesi nedeniyle cinsiyet karşılaştırmaları için parametrik olmayan testler (Wilcoxon İşaretli Sıralar Testi) kullanılırken, değişkenler arasındaki ilişkiler için Spearman Korelasyon Analizi uygulanmıştır. Tüm sporcular için ortalama PSQI Toplam Skoru 5.97 ± 2.74 olup, bu değer "kötü uyku kalitesini" gösteren eşiğe (>6) yakındır. Cinsiyetler arasında Toplam PSQI Skorunda anlamlı bir fark olmamasına rağmen (p = 0.752), kadın sporcular Alışılmış Uyku Verimliliği alt ölçeğinde erkeklere göre (0.17 ± 0.45) anlamlı derecede daha yüksek bir skor (0.59 ± 1.09) göstermiştir (p = 0.036). Ayrıca, PSQI Gündüz İşlev Bozukluğu alt bileşeni ile turnuva sonuçları arasında, özellikle erkek katılımcılarda, negatif ve anlamlı bir korelasyon (p = 0.015, r = -0.388) bulunmuştur. Uluslararası profesyonel badminton oyuncuları genel uyku kalitesinde bozulmaya eğilimli olup, kadın sporcular erkek meslektaşlarına göre anlamlı ölçüde daha düşük uyku verimliliği sergilemektedir.
