Because achievement goals are context-specific, the study first investigated the evolution of two achievement goals of 697 regular athletes, namely self-approach goals (improving oneself) and self-avoidance goals (avoiding regression), before and during the confinement situation and the physical exercise restrictions due to the Covid-19 outbreak. Secondly, we sought to examine the potential predicting role of self-approach and self-avoidance goals on athletes’ intention to exercise during confinement, while self-avoidance goals were usually not related to this outcome in a more traditional context. Using a retrospective correlational design, the results of repeated measures ANOVA highlighted that self-approach goals scores decreased while self-avoidance goals scores increased and became the athletes’ goals with the highest score during confinement. The results of hierarchical regression analyses showed that self-approach and self-avoidance goals were both found as positive predictors of intention to exercise during confinement. This study reinforces the assumptions that (a) a specific achievement setting encourages the adoption of different achievement goals (which was identified here with regular athletes in an unusual context of confinement), (b) self-avoidance goals are not always maladaptive, and (c) shifting among multiple goals according to the requirements of the situation may be beneficial.  相似文献

The present study investigated the impact of physical exercise on the executive shifting function in 24 participants low and 24 participants high in agentic extraversion and tested whether agentic extraversion moderated the exercise effect. Participants accomplished a shifting task and a control task that employed the same materials and response procedure as the shifting task but required less central-executive processing. Physical exercise was varied within subjects. The order of conditions was counterbalanced. After resting, the high agentic extraversion group showed higher cognitive flexibility than the low agentic extraversion group, whereas only the low agentic extraversion group improved after exercise. The results showed that agentic extraversion moderated the exercise effect on shifting performance. Implications concerning the hypothetical dopaminergic mediation were discussed.  相似文献

Abstract

Background: A dearth of research exists about the health behaviors of transgender young people (TYP). As we seek to learn more about transgender (trans) health, community-based participatory research (CBPR) approaches are crucial for incorporating TYP’s needs into the formulation of research questions and development of health behavior programing.

Aim: Explore body image and exercise as priorities among TYP.

Methods: Trans masculine young adults (N?=?16) in a small city in the Midwest took part in semi-structured interviews about their health behaviors and priorities. Theme analysis was used to capture key patterns in participants’ responses. Specific analysis steps included initial and more specific coding, analytical memos, organizational matrices and reports, and discussion about results with participants.

Results: Participants identified exercise and body image as connected primary health concerns. They discussed these issues in terms of three themes: Body shape as motivation for exercise; Poor body image, stigma and fear as exercise barriers, and; Exercise or lack of, as destructive. Participants wanted to exercise to achieve a certain body shape, not for health or as stress relief. They cited gyms as unwelcoming, however. They also worried about discrimination and did not feel sufficiently comfortable with their bodies to exercise. When they could not exercise, they used harmful behaviors, like restricted eating, to achieve a specific male shape.

Conclusions: Using participatory methods allowed us to understand the priorities of a group of Transmasculine young people. Our findings suggest that it is important to continue to explore TYP’s body-related motivations for exercise and understand the balance between exercise as a positive health behavior, and a potentially harmful one, in light of TYP’s complex body image concerns. Trans friendly gyms and gym policies could promote safe exercise and continued anti trans discrimination work and policy advocacy can promote the safety of TYP in all spaces.  相似文献

Objective: The current investigation extends ecological momentary assessment (EMA) and daily diary weight stigma research in internalised weight bias (IWB). This investigation used daily diaries to examine the relationship between IWB, mood, coping, body appreciation, exercise behaviours and eating behaviours. Design: The study sample consisted of individuals who were overweight or obese (85% female) with MBMI?=?36.0, SDBMI?=?6.2. Participants completed a daily diary each evening and wore a Fitbit for 30 days. Main Outcome Measures: Participants reported on IWB, mood, coping, body appreciation, exercise behaviours and eating behaviours.

Results: Both within- and between-subjects IWB were significantly related to positive affect, negative affect, several coping responses, body appreciation, eating behaviours and the urge to avoid exercise. Exploratory analyses indicated that positive and negative affect mediated many of the associations between IWB and coping responses, body appreciation, and eating and exercise behaviours.

Conclusion: This investigation provides evidence that IWB experiences have daily impacts on psychological well-being, body appreciation, coping, eating and exercise behaviours. Also, this study raises awareness about IWB and its potential impact on psychological well-being and health behaviours.  相似文献
