“…Future research should seek to establish a list of both contextual and individual-level underpinnings of sport burnout and engagement. Findings from the area of organizational science could become a valuable starting point in this context (e.g., Maslach and Leiter 2008;Waleriańczyk et al 2019); however, due to the specificity of the area of sport activity, certain mechanisms characteristic of this domain of human functioning (e.g., associated with physiological responses to extreme physical effort) should also be taken into account. Furthermore, applying the SES to individuals with various levels of exercising habits would provide further evidence for the scale's validity and broaden the findings reported in the present paper.…”

The concept of sport engagement, emerging from the application of major ideas of positive psychology in sport science, has become a valuable conceptual and practical addition to understanding athlete burnout. The present article reports the major results of an attempt to develop a Polish version of the Sport Engagement Scale, a brief metric created to measure athletes' engagement for both research and practical purposes. Study 1, conducted on a sample of Polish athletes (N = 214) supports the original threefactor structure of engagement comprising the dimensions of Vigor, Dedication, and Absorption. A single-factor model also fit the data well, suggesting that calculating a general engagement factor is also justifiable. The internal consistency of the scale, as well as its associations with athletic burnout, competition anxiety, personality traits, declared sport level, and number of hours spent in training, provide evidence for sufficient concurrent criterion validity and the reliability of the scale for both research and applied purposes. Study 2, conducted on a sample of athletes taking part in a half marathon run (N = 135), provides evidence for the scale's predictive criterion validity with respect to objective performance: greater engagement, particularly scores in the Vigor subscale, predicted significantly better running performance. In the discussion, we summarize the present findings, commenting on their limitations and highlighting future research paths for the phenomenon of sport engagement.

“…However, recent reports showed that higher social jetlag is associated with job-related stress [ 61 ] and with anxiety symptoms in adolescents [ 62 ]. Other psychosocial factors such as professional or school burnout [ 63 , 64 ] were previously reported to show either no or negative correlation with social jetlag.…”

Study Objectives Social jetlag manifests as a difference of sleep timing on workdays and free days. Social jetlag is often associated with shorter, lower quality sleep, so it is unclear how much the chronic circadian misalignment contributes to observed negative health outcomes. We aimed to (1) investigate associations between social jetlag, chronotype (one of its determinants), and the levels of health markers; (2) to describe factors associated with social jetlag; (3) to examine whether working from home can reduce social jetlag. Methods Adult respondents participated in a nationally representative longitudinal survey of Czech households (individuals in each wave: n2018/19/20=5132/1957/1533), which included Munich ChronoType Questionnaire to evaluate chronotype and social jetlag. A subset provided blood samples (n2019=1957) for detection of nine biomarkers and was surveyed in three successive years (social jetlag calculated for n2018/19/20=3930/1601/1237). Data were analyzed by nonparametric univariate tests and mixed-effects multivariate regression with social jetlag, chronotype, sex, age, BMI and reported diseases as predictors and biomarker levels as outcomes. Results Higher social jetlag (≥0.65h) was significantly associated with increased levels of total cholesterol and low-density lipoprotein cholesterol, particularly in participants older than 50 years (Mann-Whitney, men: pCHL=0.0005, pLDL=0.0009; women: pCHL=0.0079, pLDL=0.0068). Extreme chronotypes were associated with cardiovascular disease risk markers regardless of social jetlag (Kruskal-Wallis, p<0.0001). Commuting to work and time stress were identified as important contributors to social jetlag. Individual longitudinal data showed that working from home decreased social jetlag and prolonged sleep. Conclusions We report significant associations between sleep phase preference, social jetlag and cardio-metabolic biomarkers.

“…4 Besides, better synchronization of older adults to external natural/societal cues might also be responsible for lesser desynchronization of biological rhythm. 14 More SJL might also imply disturbed sleep-wake patterns and more sleep loss in young compared to aged. 1,15 Delayed MST and higher SJL in females compared to males corroborates with our latest report suggesting higher susceptibility for alteration in the sleep-wake pattern during this lockdown which might be due to their longer digital time exposure during the lockdown.…”

Background: India, being the third worst affected country from COVID-19 pandemic at the time of study, faced complete lockdown to minimize community transmission that confined people to social isolation for extended durations. Design and Methods: Therefore, we conducted an online questionnaire-based survey for the Indian population after 37 days of complete lockdown to assess the integrative effects of such home restriction and social isolation on mid-sleep time, social jetlag, and their associated psychosocial behaviour. From the reports of sleep onset and waking-up times before and during lockdown as obtained from a total of 1511 respondents of ≥18 years, mid-sleep time (MST) and social jetlag (SJL) were calculated. Participants also rated their psychosocial behaviour related variables on a Likert scale. Results: Significantly delayed MST was noted during the lockdown. The majority showed reduced social jetlag; however, younger people and female subjects exhibited more SJL with delay in MST. Also, delayed MST and elevated SJL problems were more clearly demonstrated in people exhibiting more disturbances in sleep quality and daily routine, lower general mood status, irregular feeding habits (snacking frequency), worsened personal relationship, quality of life, and increased daydreaming events.Conclusion: The study emphasizes the importance of maintaining a regular daily routine with respect to sleep-wake patterns and eating habits to minimize the impact of such a crisis situation on sleep behaviour, social jetlag, and associated psychosocial wellbeing.
