This study explored the organizational stressors encountered by the "team behind the team" (viz. those operating in sport science and management roles) in elite sport and the consequences these can have. 40 support personnel working in elite sport were interviewed.Thematic analyses unveiled 36 lower-and six higher-order themes, which were separated into stressors encountered (e.g., relationship and interpersonal, physical resource, contractual and performance development, organizational structure and logistical) and their consequences (e.g., emotions and outcomes). Building on extant work, this study moves the focus beyond athletes' stress experiences to provide novel insight into those operating in sport science and management roles. The findings offer original insight into the educational needs of sport science and management staff, which can inform practitioners who face increasing demands to work with such personnel, and raise sports organizations' awareness of their duty of care to employees and the factors that need to be managed.
We evaluated the durability of IgG responses specific to SARS-CoV-2 nucleocapsid (N), receptor binding domain (RBD), and spike (S) antigens in saliva up to 8 months after RT-PCR-confirmed COVID-19 using a multiplex salivary assay. We estimated a half-life of 64 days (d) (95% CI: 49, 80 d) for N, 100 d for RBD (95% CI: 58, 141 d), and 148 d (95% CI: 62, 238 d) for S IgG responses in saliva, consistent with half-life estimates previously reported in blood. Saliva can serve as an alternative to blood to monitor humoral immune responses on a large scale following natural SARS-CoV-2 infection and vaccination for surveillance and assessment of population immunity.
The frequency, severity, and forms of symptoms months after coronavirus 2019 are poorly understood, especially in community settings. To better understand and characterize symptoms months after community-based COVID-19, a retrospective cohort analysis was conducted. Three hundred and twentyeight consecutive persons with a positive test for SARS-CoV-2 in the Johns Hopkins Health System, Maryland, March−May 2020, were selected for the study. Symptom occurrence and severity were measured through questionnaires. Of 328 persons evaluated, a median of 242 days (109−478 days) from the initial positive SARS-CoV-2 test, 33.2% reported not being fully recovered and 4.9% reported symptoms that constrained daily activities. Compared to those who reported being fully recovered, those with post-acute sequelae were more likely to report a prior history of heart attack (p < 0.01). Among those reporting long-term symptoms, men and women were equally represented (men = 34.8%, women = 34.6%), but only women reported symptoms that constrained daily activities, and 56% of them were caregivers. The types of new or persistent symptoms varied, and for many, included a deviation from prior COVID-19 health, such as being less able to exercise, walk, concentrate, or breathe. A limitation is that self-report of symptoms might be biased and/or caused by factors other than COVID-19. Overall, even in a community setting, symptoms may persist months after COVID-19 reducing daily activities including caring for dependents.
Effectively motivating social distancing—keeping a physical distance from others —has become a global public health priority during the COVID-19 pandemic. This cross-country preregistered experiment (n=25,718 in 89 countries) tested hypotheses derived from self-determination theory concerning generalizable positive and negative outcomes of different motivational messages encouraging social distancing. Participants were randomly assigned to three conditions: an autonomy-supportive message promoting reflective choices, a controlling message that was restrictive and shaming, or no message. Results partially supported experimental hypotheses: the controlling message increased defiance relative to the autonomy-supportive message and increased controlled motivation (which itself correlated with more defiance and less long-term behavioural intentions to engage in social distancing) relative to no message, but messages did not influence behavioural intentions. Despite small experimental effects on defiance and motivation (rs= .07 and .10), this work highlights the potential harm of controlling public health messages and potential benefits of autonomy-supportive ones.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
