This study examined the association between motivational processes, psychological distress (depression, anxiety, and stress), and burnout among winter sports athletes within the Hierarchical Model of Intrinsic and Extrinsic Motivation (HMIEM). A total of 685 winter sport athletes participated in this study (377 males, 308 females, age range 18–25 years), from three sport universities across nine winter sports. They completed five psychometric inventories related to motivational factors and mental disorders. Overall, a task-oriented climate showed a positive association with basic psychological needs, eliciting a positive pathway to autonomous and controlled motivation. In contrast, an ego-oriented climate showed a negative association with basic psychological needs, eliciting a negative pathway to amotivation. Autonomous and controlled motivation were negatively associated with symptoms of psychological distress and burnout, while amotivation was positively associated with symptoms of psychological distress and burnout. These findings highlight the complex relationships between various motivational factors and mental health disorders among winter sport athletes, and support the essential requirement for adding mental health factors to the outcomes of the HMIEM sequence.

The present research investigated the association between a series of motivational factors and burnout syndrome among elite skiers at the contextual level within the Hierarchical Model of Intrinsic and Extrinsic Motivation (HMIEM). There are 352 subjects (258 males, 94 females, aged 18 to 25 years) across five skiing events from three sport universities in this study. Four psychological scales related to motivational factors and burnout syndrome were completed by subjects. Overall, the result showed that a task-involving climate had a positive relationship with basic psychological needs, eliciting a positive pathway to autonomous motivation, and thus negatively affecting burnout syndromes. On the other hand, an ego-involving climate had a negative relationship with basic psychological needs, eliciting a negative pathway to amotivation, and then positively affecting burnout syndromes. The results underscore the intricate associations between a variety of motivational factors and athletes’ burnout syndrome, supporting the need to incorporate burnout syndrome elements into the outcomes of HMIEM sequence.

Liver fibrosis is inevitable in the healing process of liver injury. Liver fibrosis will develop into liver cirrhosis unless the damaging factors are removed. This study investigated the potential therapy of Bama pig adipose-derived mesenchymal stem cells in a carbon tetrachloride-induced liver fibrosis Institute of Cancer Research strain mice model. Adipose-derived mesenchymal stem cells were injected intravenously into the tails of mice of the Institute of Cancer Research strain that had been treated with carbon tetrachloride for 4 weeks. Survival rate, migration, and proliferation of adipose-derived mesenchymal stem cells in the liver were observed by histochemistry, fluorescent labeling, and serological detection. At 1, 2, and 3 weeks after adipose-derived mesenchymal stem cell injection, liver fibrosis was significantly ameliorated. The injected adipose-derived mesenchymal stem cells had hepatic differentiation potential in vivo, and the survival rate of adipose-derived mesenchymal stem cells declined over time. The findings in this study confirmed that adipose-derived mesenchymal stem cells derived from the Bama pig can be used in the treatment of liver fibrosis, and the grafted adipose-derived mesenchy-mal stem cells can migrate, survive, and differentiate into hepatic cells in vivo.

The aim of this study was to examine the effect of brand familiarity on sponsor recall. 196 respondents in China and Singapore were exposed to video clips from the 14th FINA World Championships held in Shanghai, China in 2011, and the 28th South East Asian (SEA) Games held in Singapore in 2015. It was found that respondents were more likely to recall familiar brands. The findings provided empirical evidence that commercial organisations should first consider the level of brand familiarity in the target market before embarking on sports sponsorship. This is because sports sponsorship is more effective when the brand is familiar with the target spectators. In addition, this study suggests that it may be more effective for commercial organisations that are not established internationally to consider sponsoring events that targets spectators from regions that they are already operating in. This will allow their sponsorship to be more effective.

This study examined the relationships between motivational processes and mental toughness in college skiers based on the self-determination theory (SDT). A total of 332 participants from four skiing items completed four psychological scales assessing motivational factors and mental toughness. The findings revealed that a task-involving climate is positively associated with basic psychological needs, eliciting a positive pathway to autonomous motivation and controlled motivation, thereby positively affecting mental toughness. In contrast, an ego-involving climate is negatively associated with basic psychological needs, eliciting a negative pathway to amotivation, thus negatively affecting mental toughness. The findings highlight the complex interplay between a series of motivational factors and athletes’ mental toughness, underscoring the need to integrate mental-toughness-related factors into the motivational framework.
