The present study aimed to review the research literature on aquatic exercise for health promotion using bibliometric methods and CiteSpace software. The number of studies related to this topic are constantly expanding, with the USA, Brazil, and Australia the centers of this research. Most published papers fall within Sports Science, but the disciplines of Physiology, Psychology, and Rehabilitation were also found to be dominant domains for this literature. The seven most prolific authors were from Brazil or Spain. The most frequently cited references focused on sub-topics of physiology, biochemistry, physical fitness, psychological health, cardiovascular disease, and joint disease. New research trends have shifted to the promotion of cardiovascular health in clinical populations (stroke, overweight, hypertension, endothelium dysfunctional, obese, inflammation, antioxidant, heart failure). Overall, this review found that research hot spots and trends in this realm have focused on improving cardiovascular health with aquatic exercise. [ABSTRACT FROM AUTHOR]

Background: During quarantine, both physical and mental health are a concern. To the same extent that physicians are a scarce resource during this crisis, psychiatrists and psychologists are also limited in number. To help practitioners and public managers decide where to invest their resources, the present research investigated the relationships of stress, depression and state anxiety levels with sociodemographic and behavioural variables. Methods: Data were collected in Brazil between March, 18 and 22, 2020 in 1,468 volunteers during quarantine. Participants with a history of or current mental health illnesses were excluded leaving 1,460 individuals in the final sample. The online assessment included instruments for psychological stress, depression and state anxiety. A sociodemographic and behavioural questionnaire with 15 items was used to assess other factors. Multiple linear regression was performed for each psychological outcome to determine a hierarchy of significant predictors. Findings: Stress, depression and state anxiety levels were all predicted by gender (women higher than men), quality of nutrition, attendance in tele-psychotherapy, exercise frequency, presence of elderly persons in quarantine with the person, obligation to work outside the home, level of education (more educated, lesser risk for mental illness) and age (younger age, greater risk). Having a perceived risk factor for COVID-19 predicted depression and state anxiety, but not stress. Finally, the presence of children in quarantine with the participant was a protective factor for depression. Interpretation: Even though this research is limited by its cross-sectional design, it is possible to infer that mental health varies by demographic attributes, obligations and health behaviours. Those who report higher distress must work outside the home during quarantine, live with an elderly person and carry a risk factor for COVID-19, among other factors. Identifying those who are most vulnerable would help to prioritize those who may need the greatest psychological aid and assist public health practitioners in developing support strategies.
