    (1998) Bediz C.Ş.; Gökbel H.; Kara M.; Üçok K.; Çikrikçi E.; Ergene N.
    Background. The purpose of the present study was to compare the aerobic contribution of the Wingate anaerobic test by increasing the test load and power output Methods. Setting: The study was performed in the Physiology Department of the Faculty of Medicine, Selcuk University. Participants: Thirty sedentary male university students Volunteered to this study. Experiments: The subjects performed two Wingate tests against resistance of 75 g·kg-1 and 95 g·kg-1 body weight on Monark 818E bicycle ergometer. Breath-by-breath oxygen consumption rates were measured using an automated metabolic measurement chart (Sensormedics 2900). Aerobic contribution was determined by dividing energy equivalence of net oxygen consumption to the total work. Results. The mean total work values obtained from tests performed at 75 g·kg-1 and 95 g·kg-1 loads were 13.9 ± 1.5 kjoules and 14.5 ± 1.8 kjoules (t=2.32, p = 0.03). Mean total oxygen consumptions were 765 ± 105 ml and 770 ± 110 ml, respectively (t=0.24, p=0.81). Assuming 20% mechanical efficiency for both tests, aerobic contributions were calculated as 19.5 ± 3.7% and 18.9 ± 3.7%, respectively (t=l.01, p=0.30). Conclusions. Although the power outputs of the two tests were different, the difference between aerobic contributions was not statistically significant. So, it was failed to say that the increase in the power outputs might be related to higher contribution of anaerobic processes. However, if different mechanical efficiencies could be used, relationship between aerobic contributions of two tests might have been different.

    The Influence of Acute Sprint Interval Training on the Cognitive Performance of Male Basketball Players: An Investigation of Expertise-Related Differences
    (MDPI, 2023) Mancı E.; Herold F.; Günay E.; Güdücü Ç.; Müller N.G.; Bediz C.Ş.
    Highly developed cognitive abilities are an important prerequisite for reaching elite athletic levels. This study aimed to investigate the effect of an acute sprint interval training (SIT) session on the cognitive performance of amateur and elite players. Eighteen amateur and ten elite male basketball players were included in this study. They were asked to perform an acute SIT consisting of the Wingate Test (i.e., four bouts of 30 s all-out sprints) on a cycle ergometer, interspersed with 4 min of active recovery. Before and after the acute SIT, three cognitive tests (i.e., Change Detection Test, Timewall Test, Mackworth Clock Test) were performed. Exercise-induced changes in cognitive performance and between-group differences were analyzed. We did not observe significant between-group differences in the performance of any cognitive test at the pretest, but elite basketball players outperformed the amateur players in specific measures of the Change Detection Test and Timewall Test after the acute SIT (p < 0.05). In addition, for the Clock Test, only the elite basketball players’ performance improved from pre- to posttest. The current study’s findings suggest that male elite basketball players, compared to amateur basketball players, can preserve their cognitive performance after an acute bout of SIT. © 2023 by the authors.

    The Effect of the Playing Positions in Basketball on Measures of Cognitive Performance
    (Springer Nature, 2023) Mancı E.; Günay E.; Güdücü Ç.; Herold F.; Bediz C.Ş.
    Purpose: To compete at a high-performance level, an athlete needs not only extraordinary physical capabilities but also extraordinary cognitive capabilities. However, position-specific differences concerning cognitive performance capabilities in team sport athletes (e.g., basketball) have, so far, not been extensively studied. Thus, this study investigated possible position-specific differences in specific cognitive performance capabilities in a cohort of trained basketball athletes playing guard, forward, or center positions for more than 10 years. Methods: 27 male basketball players and 20 sedentary controls were included in this study. We used three cognitive tests (i.e., Change Detection Test, Timewall Test, and Mackworth Clock Test) to investigate possible cognitive performance differences concerning position-specific capabilities. Thereto, indices of cognitive performance were compared between the athletes of the different playing positions and sedentary controls. Results: In the Change Detection Test, the number of correct answers from guards was significantly higher than the one of the forwards, centers, and sedentary controls (p <.001). During the Timewall Test, centers’ timing scores were significantly higher than the one of the guards, forwards, and sedentary controls (p <.001). Concerning the Mackworth Clock Test, no significant differences between the playing positions were observed, although all basketball players outperformed sedentary controls. Conclusion: In summary, the results of this cross-sectional study provide evidence (i) that trained basketball players are equipped with superior cognitive capabilities as compared to sedentary controls, and (ii) that in trained basketball players position-related differences in specific cognitive capabilities occur. In regard to the latter, our findings suggest that guards are equipped with superior visuospatial attention and short-term memory capabilities whereas centers showed superior visuospatial perception and timing abilities. Whether such differences are caused by long-term position-specific training, are a result of a selection process, or a result of both factors needs to be investigated in future longitudinal studies. © 2023, The Author(s), under exclusive licence to Springer Nature Switzerland AG.

    The relationship between esports game genres and cognitive performance: A comparison between first-person shooter vs. multiplayer online battle arena games in younger adults
    (Elsevier B.V., 2024) Mancı E.; Güdücü Ç.; Günay E.; Güvendi G.; Campbell M.; Bediz C.Ş.
    The relationship between esports and cognitive performance has recently gained interest in scientific research. Specifically, the cognitive characteristics of popular gaming genres such as Multiplayer Online Battle Arena Games (MOBA) and First-Person Shooter (FPS) are needed to be explained. This present study aimed to compare cognitive abilities and reveal the differences between players who regularly play MOBA and FPS games. The participants were divided according to the game genres into MOBA players (n = 17; game experience = 9.17 ± 2.21 years) and FPS players (n = 22; game experience = 10.90 ± 3.62 years). Four cognitive tests (i.e., Change Detection, Mackworth Clock, Timewall, and Flanker Test) were administered to the participants via a computerized test battery. The data of the different groups were statistically compared. In the Mackworth Clock Test, FPS players had a higher percentage of correct answers than MOBA players (p =.02). The number of correct answers and reaction times obtained from the Flanker test by FPS players were higher compared to MOBA players (p =.02 and p =.01, respectively). This study revealed that the sustained attention, reaction time, and inhibition skills of FPS players are better than MOBA players. These findings may help to shed light on some of the cognitive abilities that might be more relevant to the FPS genres. © 2024 Elsevier B.V.

    The influence of acute sprint exercise on cognition, gaming performance, and cortical hemodynamics in esports players and age-matched controls
    (Springer, 2024) Mancı E.; Gençtürk U.; Günay E.; Güdücü Ç.; Herold F.; Bediz C.Ş.
    The relationship between esports and cognitive performance has recently gained increasing interest in the scientific community. However, our knowledge of the effects of acute sprint exercise (SE) on game performance and cognitive performance of esports players (as compared to age-matched controls) is scant. To address this gap, this study using a between-subjects design with pretest-posttest comparisons recruited amateur esports players aged between 18 and 35 years, and healthy age-matched controls who did not play esports games. The participants performed the Go/No-go test, Tracking Test, and the First Person Shooter (FPS) game Valorant immediately before and 5 and 30 min after SE. In addition to the behavioral performance, changes in the cortical hemodynamics of the prefrontal cortex (PFC) were recorded before and after the acute physical exercise while playing Valorant using functional near-infrared spectroscopy. The results show that amateur esports players have superior performance in both game performance (p <.001) and specific measures of cognitive performance (i.e., Tracking Test, p <.05), regardless of the sessions. After the acute physical exercise, the gaming performance in both groups improved, and amateur esports players showed a higher accuracy in the Go/No-go task 30 min after SE. Regarding PFC cortical hemodynamics, no significant difference was noticed in the oxygenation values of both groups between pre and post tests, and between-group differences (p >.05). In conclusion, our study provides evidence that (i) amateur esports players have superior cognitive performance in specific domains and (ii) an acute bout of physical exercise can increase the gaming performance of both amateur esports players and healthy age-matched controls. © The Author(s) 2024.
