Methods: 1454 elite athletes (24.1±6.7 years; 42% female; 41% individual sports) from 40 countries answered a retrospective, cross-sectional, web-based questionnaire relating to their behavioral habits pre- and during- COVID-19 lockdown, including: (i) Pittsburgh sleep quality index (PSQI); (ii) Insomnia severity index (ISI); bespoke questions about (iii) napping; and (iv) training behaviors. The association between dependent (PSQI and ISI) and independent variables (sleep, napping, and training behaviors) was determined with multiple regression and is reported as semi-partial correlation coefficient squared (in percentage). Results: 15% spent < one month, 27% spent 1-2 months and 58% spent > two months in lockdown. 29% self-reported maintaining the same training intensity during-lockdown whilst 71% reduced training intensity. PSQI (4.1±2.4 to 5.8±3.1; mean difference (MD): 1.7; 95% confidence interval of the difference (95% CI): 1.6 to 1.9) and ISI (5.1±4.7 to 7.7±6.4; MD: 2.6; 95% CI: 2.3 to 2.9) scores were higher during- compared to pre-lockdown, associated (all p<0.001) with longer sleep onset latency (PSQI: 28%; ISI: 23%), later bedtime (PSQI: 13%; ISI: 14%) and later preferred time of day to train (PSQI: 9%; ISI: 5%) during-lockdown. Those who reduced training intensity during-lockdown showed higher PSQI (p<0.001; MD: 1.25; 95% CI: 0.87 to 1.63) and ISI (p<0.001; MD: 2.5; 95% CI: 1.72 to 3.27) scores compared to those who maintained training intensity. Although the PSQI score was not affected by the lockdown duration, the ISI score was higher in athletes who spent > two months confined compared to those who spent < one month (p<0.001; MD: 1.28; 95% CI: 0.26 to 2.3). Conclusions: Reducing training intensity during the COVID-19-induced lockdown was associated with lower sleep quality and higher insomnia severity in elite athletes. Lockdown duration had further disrupting effects on elite athletes’ sleep behavior. These findings could be of relevance in future lockdown or lockdown-like situations (e.g., prolonged illness, injury, and quarantine after international travel). © 2022 Romdhani, Fullagar, Vitale, Nedelec, Rae, Ammar, Chtourou, Al-horani, BEN SAAD, Bragazzi, Donmez, Dergaa, DRISS, Farooq, Hammouda, Harroum, Hassanmirzaei, Khalladi, Khemila, Mataruna-Dos-Santos, Moussa-Chamari, Mujika, Muñoz Helú, Norouzi Fashkhami, Paineiras-Domingos, Rahbari Khaneghah, Saita, Souissi, Trabelsi, Washif, Weber, Zmijewski, Taylor, Garbarino and Chamari.Item Ramadan observance exacerbated the negative effects of COVID-19 lockdown on sleep and training behaviors: an international survey on 1681 Muslim athlete(Frontiers Media S.A., 2022-06-30) Romdhani, Mohamed; Ammar, Achraf; Trabelsi, Khaled; Chtourou, Hamdi; Vitale, Jacopo Antonino; Masmoudi, Liwa; Nedelec, Mathieu; Rae, Dale Elizabeth; Al-horani, Ramzi A.; BEN SAAD, Helmi; Bragazzi, Luigi; Donmez, Gurhan; Dergaa, Ismail; DRISS, Tarak; Farooq, Abdulaziz; Hammouda, Omar; Harroum, Nesrine; Hassanmirzaei, Bahar; Khalladi, Karim; Khemila, Syrine; Mataruna-Dos-Santos, Leonardo Jose; Moussa-Chamari, Imen; Mujika, Iñigo; Helú, Hussein Muñoz; Fashkhami, Amin Norouzi; Paineiras-Domingos, Laisa Liane; Khaneghah, Mehrshad Rahbari; Saita, Yoshitomo; Souabni, Maher; Souissi, Nizar; Washif, Jad Adrian; Weber, Johanna; Zmijewski, Piotr; Taylor, Lee; Garbarino, Sergio; Chamari, KarimObjective: Disrupted sleep and training behaviors in athletes have been reported during the COVID-19 pandemic. We aimed at investigating the combined effects of Ramadan observance and COVID-19 related lockdown in Muslim athletes. Methods: From an international sample of athletes (n = 3911), 1681 Muslim athletes (from 44 countries; 25.1 ± 8.7 years, 38% females, 41% elite, 51% team sport athletes) answered a retrospective, cross-sectional questionnaire relating to their behavioral habits pre- and during- COVID-19 lockdown, including: (i) Pittsburgh sleep quality index (PSQI); (ii) insomnia severity index (ISI); (iii) bespoke questions about training, napping, and eating behaviors, and (iv) questions related to training and sleep behaviors during-lockdown and Ramadan compared to lockdown outside of Ramadan. The survey was disseminated predominately through social media, opening July 8th and closing September 30th, 2020. Results: The lockdown reduced sleep quality and increased insomnia severity (both p<0.001). Compared to non-Muslim (n=2230), Muslim athletes reported higher PSQI and ISI scores during-lockdown (both p<0.001), but not pre-lockdown (p>0.05). Muslim athletes reported longer (p<0.001; d=0.29) and later (p<0.001; d=0.14) daytime naps, and an increase in late-night meals (p<0.001; d=0.49) during- compared to pre-lockdown. Both sleep quality (χ2=222.6; p<0.001) and training volume (χ2=342.4; p<0.001) were lower during-lockdown and Ramadan compared to lockdown outside of Ramadan in the Muslims athletes. Conclusion: Muslim athletes reported lower sleep quality and higher insomnia severity during- compared to pre-lockdown, and this was exacerbated by Ramadan observance. Therefore, further attention to Muslim athletes is warranted when a circadian disrupter (e.g., lockdown) occurs during Ramadan. © 2022 Romdhani, Ammar, Trabelsi, Chtourou, Vitale, Masmoudi, Nedelec, Rae, Al-horani, BEN SAAD, Bragazzi, Donmez, Dergaa, DRISS, Farooq, Hammouda, Harroum, Hassanmirzaei, Khalladi, Khemila, Mataruna-Dos-Santos, Moussa-Chamari, Mujika, Muñoz Helú, Norouzi Fashkhami, Paineiras-Domingos, Rahbari Khaneghah, Saita, Souabni, Souissi, Washif, Weber, Zmijewski, Taylor, Garbarino and Chamari.
