Both the Dualistic Model of Passion and Self-Determination Theory suggest that the persistence of a behaviour over time derives from the internalisation of the passion or motivation that the individual feels about the activity. However, the integration of these theoretical assumptions may lead to a better understanding of related outcomes, in particular on subjective well-being (SWB). In this context, this study aimed at systematically reviewing the relation between passion, behaviour regulation (i.e., self-determined motivation), and SWB in sport. The PRISMA 2020 protocol was used to guide the systematic review. Electronic searches were conducted in the Web of Science database and Pubmed. The following descriptors were used: SWB; passion; motivation; behavioural regulation; and sport. After the search, 12 studies were retrieved for analysis that show us the following results tendencies: harmonious passion (HP) and autonomous motivation (AM) (i.e., more self-determined forms of behaviour regulation) are positively related to SWB (i.e., life satisfaction and positive affect), while obsessive passion (OP) and controlled motivation (CM) (i.e., less self-determined forms of behaviour regulation) are negatively associated with SWB. However, no studies were found to simultaneously analyse the three theoretical constructs. These results show us the importance of developing conditions in sport contexts that promote positive feelings that take into account athletes' development of harmonious passion and self-determined behaviour regulation, in order to achieve higher levels of well-being. Nevertheless, these results also lead us to the necessity for more studies to highlight the theoretical link between passion and motivation in the context of sport, especially regarding the mediating role of motivation in the relationship between passion and well-being.

Alzheimer's disease is a type of dementia that progressively affects memory, thinking, and behavior. It can interfere with daily activities and lead to a decline in cognitive abilities over time. Exercise-based interventions can complement Alzheimer's disease treatment. Exercise is a valuable tool in all healthcare settings and has shown promise as an effective cognitive improvement intervention for people with cognitive impairments. This systematic review and meta-analysis aimed to analyze the effect of physical exercise on the QoL of subjects with Alzheimer's disease. A search was performed with the help of the electronic databases PubMed and Web of Science. Randomized controlled trials with exercise-based interventions were selected. Four studies met the inclusion criteria, which included interventions based on exercise. The effects were summarized using standardized mean differences (95% confidence intervals) using random-effect models. The results showed that exercise had no significant effect on the QoL of subjects with Alzheimer. Thus, the effect of exercise interventions on the QoL of patients with Alzheimer's disease is not conclusive. More research is needed about this topic and the way in which the QoL is assessed; the necessity to conduct an objective way to assess the QoL in this population is mandatory., Competing Interests: The authors declare no conflict of interest.

The present research aims to systematically review the determinants and reasons for swimming dropout. The systematic review was conducted through electronic searches on the Web of Knowledge and PsycInfo databases from 2 February to 29 July 2015, using the keywords dropout, withdrawal, motives, reasons, sport, framework-theories, motivation, swim*, review, attrition and compliance. Fifteen studies were found and six were fully reviewed and its data extracted and analysed. Most studies were undertaken in Canada and in the United States of America (USA), and one study was conducted in Spain. Most participants were female (65.74%), and the main reasons for dropout were 'conflicts with their trainers', 'other things to do', 'competence improvements' failure', 'parents, couples or trainers' pressure', 'lack of enjoyment' and 'get bored'. This review contributes to the present knowledge on the understanding of dropout in swimming. However, it is necessary to continue researching on this topic, validating measurement instruments and studying the motivational processes related to dropout and persistence., Competing Interests: The authors do not have any conflict of interest regarding this study.
