RESUMEN
Caffeine is recognized as one of the most effective dietary ergogenic aids in sports, yet its evidence-based effectiveness in esports is unclear. This study investigated the effects of two different doses of caffeine on the shooting performance and reaction time of 24 first-person shooter (FPS) esports players (22 men, 2 women; age = 22.29 ± 2.91 years). Participants completed three experimental trials in which they consumed either a water control (CON), a 1â mg·kg-1 BM (CAF1) or a 3â mg·kg-1 BM (CAF3) dose of caffeine. Performance measures (e.g., score, accuracy (%), hit rate (hits/sec), and shots fired) were assessed in a static clicking and reactive tracking style task on the KovaaK's FPS aim trainer. Reaction time was used to assess vigilance on the psychomotor vigilance test (PVT). Performance was measured at four time points in each trial: pre-treatment (PRE), 60â min (POST1), 80â min (POST2), and 100â min (POST3) post-treatment. Significant differences were identified using repeated-measures analysis of variances. Caffeine, irrespective of dose, significantly improved performance compared to CON for static clicking score and hit rate, reactive tracking accuracy, and reaction time on the PVT. Significant interactions between treatment and time were identified and post hoc analyses showed that compared to CON, CAF1 significantly improved static clicking score at POST1 and POST3, static clicking hit rate at POST1, reactive tracking accuracy at POST1, POST2, and POST3, and reaction time on the PVT at POST1 and POST2. Post hoc analysis also showed that compared to CON, CAF3 significantly improved static clicking score, reactive tracking accuracy, and reaction time on the PVT at all time points, in addition to static clicking hit rate at POST1 and POST3. In summary, caffeine supplementation enhances the shooting performance and reaction time of FPS esports players.
RESUMEN
PURPOSE: To examine associations between time perspective and health promotion behaviors of physical activity and weight management. DESIGN: Quantitative cross-sectional. SETTING: This study is part of the Betula project on aging, memory, and dementia in Northern Sweden. SUBJECTS: 417 older adults aged between 55 and 85 years. MEASURES: Swedish-Zimbardo Time Perspective Inventory; Physical Activity in the past year, past week, and in comparison with others of similar age; Weight Management = Body Mass Index (BMI; kg/m2). RESULTS: After controlling for age, sex, and years of education, hierarchical linear regression indicated a Balanced Time Perspective was significantly associated with more physical activity in the past year (P = .04), the past week (P < .001), and in comparison with others (P < .01). Past Negative time perspective was associated with less physical activity in the past year (P = .03), and in comparison with others (P = .03). Present Fatalistic was associated with less physical activity during the past week (P = .03), and in comparison with others (P = .01). Present Hedonistic was associated with more physical activity the past week (P = .03), and in comparison with others (P = .03). Past Negative was associated with higher BMI (P = .02), and Future Negative were associated with lower BMI (P = .01). Taken collectively, greater positivity and flexibility across time perspectives was associated with more physical activity, whereas negative oriented time perspectives related with less physical activity and poorer weight management. CONCLUSION: Time perspective can be associated with health behaviors in older adults and have implications for health across the lifespan. Health promotion interventions may target older adults' enjoyment of exercise and weight management in the present, rather than highlight potential negative health outcomes in the future.
RESUMEN
Esports have grown substantially in the last decade and may be an effective way of engaging and exposing the youth, who is not actively participating in traditional sports, to the benefits of sports related performance environments. However, due to negative stereotypes about gamers and concerns about esports, parents might be hesitant to support their children's esports participation and may instead actively discourage it. The purpose of this perspective article was to discuss the determinants of parental support based on the theory of planned behaviour. Parents attitudes seem to be mostly negative and their perceived behavioral control is likely low due to a lack of knowledge about esports. The subjective norms are mixed and seem to be growing progressively more positive. Based on the theory of planned behaviour, parents seem unlikely to support their children's esport participation, however, more research is needed. Recommendations on how to increase the likelihood of parental support are discussed.
RESUMEN
Esports research lacks game-based metrics platforms appropriate for adequately capturing esports performance. The aim of this pilot study was to assess the reliability of the KovaaK's first-person shooter (FPS) aim trainer as a metrics platform for assessing shooting proficiency in esports players. Ten FPS esports players completed two identical experimental trials (T) separated by three to five days. Each trial included four rounds (R) of testing, evaluating four shooting tasks: Micro Flicking, Macro Flicking, Strafe Tracking, and Wall Peeking. Reliability of performance outcomes (e.g., accuracy, headshot accuracy, hits per second, and total shots hit) were assessed using the intraclass correlation coefficient (ICC) and their 95% confidence intervals (CI), and significant differences were identified using repeated-measures analysis of variance (RM-ANOVA). Results indicated excellent, or good to excellent reliability for all outcome variables with the ICC estimates ranging between 0.947-0.995, with lower and upper bound 95% CIs ranging between 0.876-0.988, and 0.984-0.999, respectively. Significant improvements were seen between experimental trials in the Macro Flicking task for accuracy (p = .005) and hits per second (p = .009) only. Significant interactions between trial and round were identified in the Micro Flicking task for accuracy (p = .006), with post hoc analysis showing accuracy was significantly higher in T1R1 compared to T2R1 (87.74 ± 3.13 vs. 85.99 ± 3.05, respectively, p = .02), and in T2R4 compared to T2R2 (87.99 ± 2.89 vs. 84.70 ± 4.25, respectively, p = .049). Significant interactions were also identified in the Strafe Tracking task for headshot accuracy (p = .002), with post hoc analysis showing headshot accuracy was significantly higher in T1R2 compared to T2R2 (78.48 ± 8.15 vs. 76.79 ± 12.16, respectively, p = .003), and in T1R2 compared to T1R1 (78.48 ± 8.15 vs. 73.68 ± 17.94, respectively, p = .023). In summary, this study demonstrates that KovaaK's provides a reliable metrics platform for assessing shooting proficiency in esports, however, some variability in performance was observed.
RESUMEN
There is growing recognition of the demands and health challenges experienced by esports athletes. The purpose of this perspective paper is to draw specific attention to the mental health of competitive gamers and spur on both future research and applied initiatives focussing on this important but under-addressed topic. We will briefly discuss the prevalence of mental health concerns, domain-specific stressors, and the need for comprehensive mental health support systems tailored to the esports context. It is our hope that, with this perspective paper, we can help set a new research agenda addressing mental health in esports.
