Adolescents’ daily life has dramatically changed during the COVID-19 era due to the social restrictions that have been imposed, including closures of schools, leisure centers and sport facilities. The purpose of this study was to examine levels of well-being and mood and their relations with physical (in)activity and eating behaviors in adolescents during a lockdown period in Greece. A total of 950 adolescents (Mean Age = 14.41 years ± 1.63) participated in a web-based survey while education was conducted online and organized sport activities were interrupted. Participants showed poor well-being, insufficient physical activity levels and moderate scores of healthy eating behavior. Hierarchical regression analysis showed that, after controlling for the effect of gender and body mass index, increased physical activity and healthier eating behavior predicted better well-being (b = 0.24, p < 0.01 and b = 0.19, p < 0.01, respectively), whereas sedentariness predicted worse well-being (b = −0.16, p < 0.01). Furthermore, it was revealed that days of physical activity per week was a stronger predictor of well-being than minutes of physical activity per week, and that both in-house and out-of-house physical activity were beneficial. Considering that well-being in our study was below the threshold recommended by the World Health Organization as indicative of possible depressive symptoms, measures to increase physical activity, decrease sedentariness and improve eating behavior should become a priority for communities and policy makers.

Background Therapeutic virtual reality (VR) has emerged as an effective treatment modality for cognitive and physical training in people with mild cognitive impairment (MCI). However, to replace existing nonpharmaceutical treatment training protocols, VR platforms need significant improvement if they are to appeal to older people with symptoms of cognitive decline and meet their specific needs. Objective This study aims to design and test the acceptability, usability, and tolerability of an immersive VR platform that allows older people with MCI symptoms to simultaneously practice physical and cognitive skills on a dual task. Methods On the basis of interviews with 20 older people with MCI symptoms (15 females; mean age 76.25, SD 5.03 years) and inputs from their health care providers (formative study VR1), an interdisciplinary group of experts developed a VR system called VRADA (VR Exercise App for Dementia and Alzheimer’s Patients). Using an identical training protocol, the VRADA system was first tested with a group of 30 university students (16 females; mean age 20.86, SD 1.17 years) and then with 27 older people (19 females; mean age 73.22, SD 9.26 years) who had been diagnosed with MCI (feasibility studies VR2a and VR2b). Those in the latter group attended two Hellenic Association Day Care Centers for Alzheimer’s Disease and Related Disorders. Participants in both groups were asked to perform a dual task training protocol that combined physical and cognitive exercises in two different training conditions. In condition A, participants performed a cycling task in a lab environment while being asked by the researcher to perform oral math calculations (single-digit additions and subtractions). In condition B, participants performed a cycling task in the virtual environment while performing calculations that appeared within the VR app. Participants in both groups were assessed in the same way; this included questionnaires and semistructured interviews immediately after the experiment to capture perceptions of acceptability, usability, and tolerability, and to determine which of the two training conditions each participant preferred. Results Participants in both groups showed a significant preference for the VR condition (students: mean 0.66, SD 0.41, t29=8.74, P<.001; patients with MCI: mean 0.72, SD 0.51, t26=7.36, P<.001), as well as high acceptance scores for intended future use, attitude toward VR training, and enjoyment. System usability scale scores (82.66 for the students and 77.96 for the older group) were well above the acceptability threshold (75/100). The perceived adverse effects were minimal, indicating a satisfactory tolerability. Conclusions The findings suggest that VRADA is an acceptable, usable, and tolerable system for physical and cognitive training of older people with MCI and university students. Randomized controlled trial studies are needed to assess the efficacy of VRADA as a tool to promote physical and cognitive health in patients with MCI.

The emotional reactions of athletes in sports competitions are not only fascinating to the spectators, but also illustrate that emotions are transmitted to the outside world, thus suggesting that they are not just intrapersonal processes. From a metacognitive perspective it is important to understand why these reactions occur and how they affect sports performance. In this study the antecedents and consequences of outward emotional reactions were explored using a naturalistic qualitative video-assisted procedure. Twelve German table tennis players were video-recorded during competitive matches in their regular season. Subsequently, based on the footage, self-confrontational interviews were conducted focusing on the antecedents and consequences of outward emotional reactions. The analysis revealed several factors related to whether or not outward emotional reactions were displayed, ranging from more malleable (e.g., state-like psychological states) to less malleable (e.g., trait-like factors). In addition, the analysis revealed how outward emotional reactions have performance-related effects on one's own mental state (e.g., one's concentration) and on the psychological state of the opponent (e.g., the opponent's confidence). The present findings suggest that it is important to create an awareness of antecedents of outward emotional reactions in athletes in order to improve the use of psychological skills by athletes to control their emotional responses. In addition, the results point to the importance of the behavioural component of emotions in the emotion-performance relationship, as various intra- and interpersonal consequences that interact with the consequences of the purely subjective emotion experience were identified.

Emotional intelligence is an important variable related to the interaction and functioning of sports teams. The present study examined the relationship between players’ trait emotional intelligence and functional and dysfunctional psychobiosocial states. In particular, we examined the mediating effects of intra-team communication efficacy and role ambiguity in this relationship. The participants were 291 (174 men and 117 women) Italian players involved in various team sports (i.e., futsal, soccer, volleyball, handball, and rugby). They completed a multi-section questionnaire assessing the study variables during the early/middle part of their competitive seasons. Structural equation modeling (SEM) showed trait emotional intelligence to positively predict functional psychobiosocial states and negatively predict dysfunctional psychobiosocial states. Effective intra-team communication mediated the relationship between emotional intelligence and functional states, while role ambiguity was a mediator of the relationship between trait emotional intelligence and dysfunctional states. Overall, the results highlight the importance of examining trait emotional intelligence as an antecedent of players’ psychobiosocial states in applied sport contexts both in terms of team functioning and individual optimal sport experience.

Previous research has shown that an empowering motivational climate in organized sport has been linked to attitudes favoring migrants’ integration. The purpose of the present study was to further test the relationship between motivational climate and acculturation attitudes, and to explore the role of prosocial skills as potential mediators of this relationship in adolescent athletes from the host population. Participants were 338 (13.61 ± .95 years of age) Greek adolescents (167 girls) participating in organized sport. Participants’ acculturation attitudes, prosocial skills, and perceptions of the coach‐created motivational climate were measured. Analysis of structural models revealed that an empowering motivational climate was positively related with prosocial skills, reflecting empathy and altruism, which in turn were positively linked with acculturation attitudes favoring migrants’ integration. The results of the present study replicate previous findings regarding the links between empowering motivational climate and acculturation attitudes, and further, provide evidence that prosocial skills such as empathy and altruism mediate this relationship.

Physical activity (PA) is linked to reduced risk of depression, but research on the objectively measured PA in clinically diagnosed adult outpatients with major depressive disorder (MDD) is scarce. This study aimed to examine relationships of objectively measured PA with depression and mood. A total of 19 outpatients (6 males) with MDD, a mean age of 47.79 ± 11.67 years and mild-moderate depression participated in the study. To record PA, participants wore a triaxial accelerometer device on the right hip during waking hours for seven consecutive days. Depression and mood were assessed with self-reports immediately after day seven. Participants wore the accelerometers for a high number of days (M = 6.26 ± 1.24 days) and hours per day (13.40 ± 2.61 h), recording light (266.01 ± 100.74 min/day) or moderate (31.19 ± 24.90 min/day) PA, and sedentary time (515.33 ± 155.71 min/day). Stepwise regression analysis yield a significant prediction (p < .05) with only moderate PA contributing to the prediction of depression (Beta = -0.47, p < .05). The model explained 22% of the variance of depression. Our findings provide valuable preliminary evidence regarding the relationship between objectively measured PA and lower depression in clinically diagnosed outpatients with MDD, suggesting moderate PA may help alleviating depressive symptoms.

In our study, we had two objectives. Our first objective was to test a social-cognitive model of doping in sport. In this model, we examined moral variables (i.e., moral disengagement, moral identity, anticipated guilt) and performance motivational climate as predictors of doping likelihood and whether performance motivational climate moderates the relationship between moral disengagement and doping likelihood. The second objective was to determine whether this model is invariant across sex and country. We used a cross-sectional design. Participants were 1495 (729 females) elite football players (mean age 20.4 ± 4.4) recruited from 97 teams in the UK, Denmark and Greece. They completed questionnaires measuring the aforementioned variables. Moral disengagement positively predicted doping likelihood both directly and indirectly via anticipated guilt. The direct relationship was significant only when performance climate was perceived as average or high. Moral identity negatively predicted doping likelihood via both moral disengagement and anticipated guilt; and performance climate positively predicted doping likelihood. The model was largely invariant across sex and country. Our findings suggest that young elite football players in the UK, Denmark and Greece are less likely to use banned substances to enhance their performance, if they consider being moral an important part of who they are, and if they perceive a low performance climate in their team. Moral identity is likely to trigger feelings of guilt associated with the use of banned substances and to mobilize moral disengagement mechanisms. Our findings highlight the importance of moral variables in deterring the use of banned substances in sport.

The purpose of this study was to explore situational determinants of goal-directed self-talk and to advance our understanding of athletes’ goal-directed self-talk functions. Participants were 97 young adult athletes (Mage = 20.36; SD = 3.38), competing at regional, national, and international level. In face-to-face meetings, participants were guided to describe situations in which they had used goal-directed self-talk. Subsequently, they were asked to report what their goal-directed self-talk in these situations had been. Both inductive and deductive data analyses were used to address the research questions. Regarding the situations, participants used goal-directed self-talk mainly in a variety of situations in training, and before, during and after competition. Furthermore, they also employed self-talk to better handle substitutions, injuries and interpersonal conflicts. Regarding self-talk functions, the initial coding scheme was expanded with additional categories to add depth and specificity to the model. Specifically, newly described self-talk functions relate to performance analyses, goal-orientation promotion, reasons underlying persistence, time perceptions and down-regulation of excessive confidence. Overall, the findings of this study suggest that athletes have different self-talk functions at their disposal, to manage a large variety of situations.

The purpose of the present study was to examine whether self-regulation strategies can further extend the effect of moderate intensity exercise on smoking delay. Participants were 40 adult smokers who were randomly assigned into two groups: control and self-regulation. A repeated measures design was adopted including a neutral condition (20 min video) and an exercise condition (20 min moderate intensity exercise). The results showed that smoking delay increased significantly for both groups; however, the increase for the self-regulation group was significantly larger than that of the control group. The results supported the anti-smoking effects of acute exercise; furthermore, they highlight the usefulness of self-regulation strategies, and in particular goal setting, in extending smoking delay. The present findings provide important evidence for the exercise and smoking literature and useful directions for the development of smoking cessation interventions.

Although exercise is associated with depression relief, the effects of aerobic exercise (AE) interventions on clinically depressed adult patients have not been clearly supported. The purpose of this meta‐analysis was to examine the antidepressant effects of AE versus nonexercise comparators exclusively for depressed adults (18–65 years) recruited through mental health services with a referral or clinical diagnosis of major depression. Eleven e‐databases and bibliographies of 19 systematic reviews were searched for relevant randomized controlled clinical trials. A random effects meta‐analysis (Hedges’ g criterion) was employed for pooling postintervention scores of depression. Heterogeneity and publication bias were examined. Studies were coded considering characteristics of participants and interventions, outcomes and comparisons made, and study design; accordingly, sensitivity and subgroup analyses were calculated. Across 11 eligible trials (13 comparisons) involving 455 patients, AE was delivered on average for 45 min, at moderate intensity, three times/week, for 9.2 weeks and showed a significantly large overall antidepressant effect (g = –0.79, 95% confidence interval = –1.01, –0.57, P < 0.00) with low and nonstatistically significant heterogeneity (I2 = 21%). No publication bias was found. Sensitivity analyses revealed large or moderate to large antidepressant effects for AE (I2 ≤ 30%) among trials with lower risk of bias, trials with short‐term interventions (up to 4 weeks), and trials involving individual preferences for exercise. Subgroup analyses revealed comparable effects for AE across various settings and delivery formats, and in both outpatients and inpatients regardless symptom severity. Notwithstanding the small number of trials reviewed, AE emerged as an effective antidepressant intervention.

Zusammenfassung. Bei der Erforschung des Zusammenhangs zwischen Emotionen und sportlicher Leistung wurde bisher fast ausschließlich das subjektive Erleben der Sporttreibenden untersucht. Dabei war es gängige Praxis Emotionen mit Fragebögen oder Interviews prospektiv bzw. retrospektiv zu erfassen. Ferner wurden in Experimenten Emotionen erzeugt, um anschließend deren Einfluss auf zum Beispiel die sportliche Leistung zu messen. Da Emotionen jedoch auch anhand von Veränderungen im Gesicht, der Gestik, der Körperhaltung oder der Stimme beobachtbar sind, wird in diesem Beitrag dafür argumentiert, zukünftig auch die Verhaltenskomponente von Emotionen verstärkt miteinzubeziehen. Bei der systematischen Verhaltensbeobachtung können Emotionen „online“ in ihrem natürlichen Kontext erfasst werden. Darüber hinaus wird darauf eingegangen, wie Veränderungen im beobachtbaren Verhalten leistungsrelevante Konsequenzen sowohl für die Person selbst als auch für andere Personen (z.B. Gegner oder Gegnerin) haben können, die nur sehr bedingt durch die Erlebniskomponente einer Emotion erklärt werden können. Abschließend werden mögliche Herausforderungen, die mit der Erforschung der Verhaltenskomponente von Emotionen im Zusammenhang stehen, diskutiert.

Over the last 20 years research investigating self-talk in the context of sport has expanded rapidly enhancing our understanding of the construct. In the present article, we provide a brief historical review of the sports-oriented self-talk literature. In so doing we identify landmark investigations and review conceptual, research, and measurement themes present within the literature. We review this empirically based literature, distinguishing between three time periods: (1) the early foundations of self-talk research, up to the end of the 1990s; (2) the developmental years of systematic self-talk research during the 2000s; and (3) the modern day maturation of self-talk research, post-2011.

This study explored the effectiveness of self-talk strategies on task performance under conditions of external distraction in laboratory and field experiments. In the laboratory experiment, 28 sport science students (Mage 21.48±1.58 years) were tested on a computer game requiring attention and fine execution following a baseline assessment and a short self-talk training. In the field experiment, 28 female basketball players (Mage 20.96±4.51 years) were tested on free-throwing, following a baseline assessment and a six-week intervention. In both settings the final assessment took place under conditions of external distraction (noncontinuous, sudden, loud noise). Analyses of covariance showed that participants of the self-talk group performed better than participants of the control group. Findings suggest that self-talk can counter the effects of distraction on performance, and indicate that the attentional effects of self-talk is a viable mechanism to explain the facilitating effects of self-talk on performance.

The study examined the effects of a motivational self-talk intervention on endurance cycling performance in hot conditions. Participants were 16 physically active adult men. After a baseline VO2 peak assessment and two training sessions, participants completed a 30 min cycling trial in a hot environment (35°C, 45% relative humidity) while maintaining a steady rate of perceived exertion. Participants of the intervention group produced greater power output during the final third of the trial. Findings suggest that the self-talk strategy seems to have compromised the aversive effects of the demanding environmental conditions and provide support for the psychobiological model of endurance performance.

Grounded on self-determination theory, this study aimed to explore the relationships between basic needs satisfaction, motivational regulations, and athletes’ automatic self-talk, and examine the potential mediating role of autonomous and controlled motivation in the relationships between basic needs satisfaction and athletes’ automatic self-talk. A cross-sectional design was employed. Athletes (N = 381; mean age 16.54) from a variety of individual (n = 132) and team sports (n = 249) completed a multisection questionnaire tapping the targeted variables. Structural equation modeling was used to test the hypothesized relationships through a direct, a fully mediated, and a partially mediated model. The analyses provided best support for the partially mediated model which showed that (a) the relationships between the need for competence and athletes’ positive and negative self-talk were partially mediated by autonomous motivation; (b) the relationships between the need for relatedness and athletes’ positive and negative self-talk were fully mediated by autonomous motivation; (c) the relationship between the need for autonomy and positive self-talk was partially mediated by autonomous motivation, whereas the relationship between the need for autonomy and negative self-talk was fully mediated by autonomous and controlled motivation. Overall, our self-determination theory-derived hypotheses were largely supported. These findings stress the importance of basic need satisfaction and motivational regulations, as factors that influence athletes’ automatic self talk and suggest that sport environments which support athletes’ basic psychological needs are likely to foster more autonomous motivation toward sport and maximize athletes’ positive self-talk, while minimizing negative self-talk.

Self-talk interventions in sport have been receiving increased research attention in recent years. The findings have provided robust support that self-talk strategies enhance sport performance. Identifying the mechanisms that explain the beneficial effects of self-talk is important for developing a comprehensive self-talk theory and informing practice. Among the mechanisms proposed to explaining the effectiveness of self-talk, is its attentional effects. This article reviews the literature considering the effects of self-talk on attention. The findings suggest that self-talk can help enhancing attentional focus and attentional performance, but also help countering the aversive effects of distraction and ego depletion. The present evidence suggests that attention is a potential key mechanism in the self-talk performance relationship.
