The aim of this study was to analyze the moderating influence of physical activity (PA) and dietary habits on the impact of the COVID-19 pandemic experience on sleep quality in elite and amateur athletes. Materials and methods: A total of 1,420 elite (40.1%) and amateur (59.9%) athletes (41% women; 59% men) from 14 different countries participated in a cross-sectional design study. Data were collected using a battery of questionnaires that identified sociodemographic data, sleep quality index, PA levels, dietary habits, and the athletes' perception of their experience during the COVID-19 pandemic. Means and standard deviations were calculated for each variable. The analysis of variances and the correlation between variables were carried out with non-parametric statistics. A simple moderation effect was calculated to analyze the interaction between PA or dietary habits on the perception of the COVID-19 experience effect on sleep quality in elite and amateur athletes. Results: The PA level of elite athletes was higher than amateur athletes during COVID-19 (p < 0.001). However, the PA level of both categories of athletes was lower during COVID-19 than pre-COVID-19 (p < 0.01). In addition, amateurs had a higher diet quality than elite athletes during the pandemic (p = 0.014). The perception of the COVID-19 experience as controllable was significantly higher (p = 0.020) among elite athletes. In addition, two moderating effects had significant interactions. For amateur athletes, the PA level moderated the effect of controllable COVID-19 experience on sleep quality [F(3,777) = 3.05; p = 0.028], while for elite athletes, the same effect was moderated by dietary habits [F(3,506) = 4.47, p = 0.004]. Conclusion: Elite athletes had different lifestyle behaviors compared to amateurs during the COVID-19 lockdown. Furthermore, the relevance of maintaining high levels of PA for amateurs and good quality dietary habits by elite athletes was noted by the moderating effect that both variables had on the influence of the controllable experience during the COVID-19 pandemic on sleep quality.

This study investigates the association between physical-activity levels and sleep patterns in quarantined individuals. An international Google online survey was launched in April 6th, 2020 for 12-weeks. Forty-one research organizations from Europe, North-Africa, Western-Asia, and the Americas promoted the survey through their networks to the general society, which was made available in 14 languages. The survey was presented in a differential format with questions related to responses “before” and “during” the confinement period. Participants responded to the Pittsburgh Sleep Quality Index (PSQI) questionnaire and the short form of the International Physical Activity Questionnaire. 5056 replies (59.4% female), from Europe (46.4%), Western-Asia (25.4%), America (14.8%) and North-Africa (13.3%) were analysed. The COVID-19 home confinement led to impaired sleep quality, as evidenced by the increase in the global PSQI score (4.37 ± 2.71 before home confinement vs. 5.32 ± 3.23 during home confinement) (p < 0.001). The frequency of individuals experiencing a good sleep decreased from 61% (n = 3063) before home confinement to 48% (n = 2405) during home confinement with highly active individuals experienced better sleep quality (p < 0.001) in both conditions. Time spent engaged in all physical-activity and the metabolic equivalent of task in each physical-activity category (i.e., vigorous, moderate, walking) decreased significantly during COVID-19 home confinement (p < 0.001). The number of hours of daily-sitting increased by ~2 hours/days during home confinement (p < 0.001). COVID-19 home confinement resulted in significantly negative alterations in sleep patterns and physical-activity levels. To maintain health during home confinement, physical-activity promotion and sleep hygiene education and support are strongly warranted. © 2021 Institute of Sport.

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.Item Sleep Quality and Physical Activity as Predictors of Mental Wellbeing Variance in Older Adults during COVID-19 Lockdown: ECLB COVID-19 International Online Survey(MDPI AG, 2021) Trabelsi, Khaled; Ammar, Achraf; Masmoudi, Liwa; Boukhris, Omar; Chtourou, Hamdi; Bouaziz, Bassem; Brach, Michael; Bentlage, Ellen; How, Daniella; Ahmed, Mona; Mueller, Patrick; Mueller, Notger; Hsouna, Hsen; Elghoul, Yousri; Romdhani, Mohamed; Hammouda, Omar; Paineiras-Domingos, Laisa Liane; Braakman-Jansen, Annemarie; Wrede, Christian; Bastoni, Sofia; Pernambuco, Carlos Soares; Mataruna-Dos-Santos, Leonardo Jose; Taheri, Morteza; Irandoust, Khadijeh; Bragazzi, Nicola L.; Strahler, Jana; Washif, Jad Adrian; Andreeva, Albina; Bailey, Stephen J.; Acton, Jarred; Mitchell, Emma; Bott, Nicholas T.; Gargouri, Faiez; Chaari, Lotfi; Batatia, Hadj; Khoshnami, Samira C.; Samara, Evangelia; Zisi, Vasiliki; Sankar, Parasanth; Ahmed, Waseem N.; Ali, Gamal Mohamed; Abdelkarim, Osama; Jarraya, Mohamed; El Abed, Kais; Moalla, Wassim; Souissi, Nafaa; Aloui, Asma; Souissi, Nizar; Gemert-Pijnen, Lisette Van; Riemann, Bryan L.; Riemann, Laurel; Delhey, Jan; Gómez-Raja, Jonathan; Epstein, Monique; Sanderman, Robbert; Schulz, Sebastian; Jerg, Achim; Al-Horani, Ramzi; Mansi, Taysir; Dergaa, Ismail; Jmail, Mohamed; Barbosa, Fernando; Ferreira-Santos, Fernando; Šimunič, Boštjan; Pišot, Rado; Pišot, Saša; Gaggioli, Andrea; Steinacker, Jürgen; Zmijewski, Piotr; Apfelbacher, Christian; Glenn, Jordan M.; Khacharem, Aïmen; Clark, Cain C.T.; Saad, Helmi Ben; Chamari, Karim; Driss, Tarak; Hoekelmann, Anita; ECLB-COVID19 ConsortiumBackground. The COVID-19 lockdown could engender disruption to lifestyle behaviors, thus impairing mental wellbeing in the general population. This study investigated whether socio-demographic variables, changes in physical activity, and sleep quality from pre-to during lockdown were predictors of change in mental wellbeing in quarantined older adults. Methods. A 12-week international online survey was launched in 14 languages on 6 April 2020. Forty-one research insti-tutions from Europe, Western-Asia, North-Africa, and the Americas, promoted the survey. The survey was presented in a differential format with questions related to responses “pre” and “during” the lockdown period. Participants responded to the Short Warwick–Edinburgh Mental Wellbeing Scale, the Pittsburgh Sleep Quality Index (PSQI) questionnaire, and the short form of the International Physical Activity Questionnaire. Results. Replies from older adults (aged >55 years, n = 517), mainly from Europe (50.1%), Western-Asia (6.8%), America (30%), and North-Africa (9.3%) were analyzed. The COVID-19 lockdown led to significantly decreased mental wellbeing, sleep quality, and total physical activity energy expenditure levels (all p < 0.001). Regression analysis showed that the change in total PSQI score and total physical activity energy expenditure (F(2, 514) = 66.41 p < 0.001) were significant predictors of the decrease in mental wellbeing from pre-to during lockdown (p < 0.001, R2: 0.20). Conclusion. COVID-19 lockdown deleteriously affected physical activity and sleep patterns. Furthermore, change in the total PSQI score and total physical activity energy expenditure were significant predictors for the decrease in mental wellbeing. © 2021 by the author.
