Virtual reality (VR) technology is being increasingly used by athletes, coaches, and other sport-related professionals. The present systematic review aimed to document research on the application of VR to sport to better understand the outcomes that have emerged in this work. Research literature databases were searched and the results screened to identify articles reporting applications of interactive VR to sport with healthy human participants. Twenty articles were identified and coded to document the study aims, research designs, participant characteristics, sport types, VR technology, measures, and key findings. From the review, it was shown that interactive VR applications have enhanced a range of performance, physiological, and psychological outcomes. The specific effects have been influenced by factors related to the athlete and the VR system, which comprises athlete factors, VR environment factors, task factors, and the non-VR environment factors. Important variables include the presence of others in the virtual environment, competitiveness, task autonomy, immersion, attentional focus, and feedback. The majority of research has been conducted on endurance sports, such as running, cycling, and rowing, and more research is required to examine the use of interactive VR in skill-based sports. Additional directions for future research and reporting standards for researchers are suggested.
The ACT intervention, delivered via DVD for the promotion of physical activity, proved a simple, efficient, and accessible method to encourage positive short-term increases in an important health-promoting behaviour. Statement of contribution What is already known? ACT interventions can increase physical activity levels through augmenting initiatory self-regulatory control. Face-to-face delivery presents challenges of accessibility and feasibility for community implementation. There is a need for effective interventions that maximize impact while minimizing inconvenience. What does this study add? Supplementing a walking programme with a self-managed ACT DVD produced significant increases in physical activity. The ACT DVD is a convenient, accessible, and potentially cost-effective approach to physical activity initiation. ACT lends itself to implementation as a self-managed electronically delivered intervention.
The present study investigated the effectiveness of two cognitive strategies for resisting a craved food. One-hundred-and-ten self-identified chocolate cravers were randomised to a waiting list control condition or to receive a 60-minute standardised group intervention on cognitive restructuring (CR) or cognitive defusion (CD). All participants were provided with a bag of chocolates which they were instructed to carry with them for seven days and try to resist eating; uneaten chocolates were returned at the end of the study period. Measures included chocolate consumption and other behavioural, cognitive and evaluative self-reported outcomes. Overall, the odds of abstinence from chocolate were 3.26 times higher for participants in the CD than the CR condition. The effect of the interventions depended on baseline cognitive distress levels; for individuals at high levels of cognitive distress the CD condition led to significantly more restraint from chocolate than both the CR and control conditions. In addition, CD led to greater self-reported improvements in eating behaviours during the study period and was rated significantly easier to use and apply than CR. CD is discussed as a simple and efficient approach to manage food cravings and, potentially, other behavioural contributors to obesity.

4Furthermore, we investigated whether these effects were moderated by inhibitory self- to assess consumption of unhealthy snack foods. Inhibitory self-control was measured using a 10 self-report scale. As predicted, the implicit evaluation of unhealthy food became more it suggests that an intervention that retrains implicit food evaluations could be effective at 18 reducing unhealthy eating, particularly among those with low inhibitory self-control.
This study explored whether mental toughness, the capacity to maintain performance under pressure, moderated the relation between physical activity intentions and subsequent behavior. Participants (N = 117) completed the Mental Toughness Index and a theory of planned behavior questionnaire. Seven days later, physical activity was assessed using the International Physical Activity Questionnaire. Attitudes, subjective norms, and perceived behavioral control explained substantial variance (63.1%) in physical activity intentions. Intentions also significantly predicted physical activity behavior. The simple slopes analyses for the moderation effect revealed a nonsignificant intention-behavior relation at low levels of mental toughness. However, intentions were significantly and positively related to physical activity when mental toughness was moderate or high, suggesting that the development of a mentally tough mindset may reduce the gap between behavior and physical activity intention. Future research is needed to confirm these findings and apply them in the design of mental toughness interventions to facilitate physical activity engagement.
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.
