    Effect of Post-Warm-Up Three Different Duration Self-Selected Active Rests on 100 Meter Swimming Performance: Preliminary Findings
    Türkmen, D; Günay, E; Güdücü, Ç; Öniz, A; Bediz, CS
    The question of when the optimal effect of warm-up is reached after the warm-up phase in swimming competitions is still not fully elucidated. The purpose of this study was to see how self-selected active rest in three different duration periods affected 100-m maximum swimming performance. Eight well-trained elite swimmers (6 males and 2 females, mean age: 17.2 +/- 3, mean 616 FINA points) were included in the study. After the participants completed a standard warm-up consisting of dryland-based dynamic warm-up (10-min) and in-water warm-up protocols (1200-m / similar to 25-min) in 3 different sessions, they observed different transition phase periods (15, 30 and 45-min) with standard clothes in their maximum heart rate of 30% and self-selected movement forms (stretching, walking, etc.) completed by active rest. Subsequently, swimmers carried out the 100-m maximum time-trial swim test using their main stroke. Tympanic temperature (Ttympanic), forehead temperature ( Tforehead), heart rate (HR), rating of perceived exertion (RPE), and maximal 100-m-time-trial ( TT) were recorded during all sessions. Measurements were evaluated in repeated measures ANOVA. Delta (.) calculation was used to score changes and strengthen the analysis. The 100-m time-trial demonstrated a trend of improvement in 30-min active rest (p=0.037). In addition, there was no difference between rest times in Tforehead, Ttympanic, HR, and RPE conditions (p>0.05). The 30-min active rest interval improved 100-m swimming performance by 1.6% and 0.8% compared to 15-min and 45-min active rest. The positive effect of pool warm-up can be maintained for up to 30 minutes with self-paced active rest.

    Determining Cognitive Performance in Athletes: A Systematic Review Focused on Methodology of Applying Cognitive Tests
    Manci, E; Herold, F; Özdalyan, F; Benli, MD; Bozkurt, Ç; Gençtürk, U; Gebel, A; Güdücü, Ç; Günay, E; Bediz, CS; Pontifex, MB; Muller, NG
    Although in recent years, there have been many studies to determine the cognitive performance of athletes, there are significant differences in the methodological approaches of these studies. Therefore, this methodology-focused systematic review aims to analyze the application methods of cognitive test studies with athletes and to provide standard recommendations for further studies. For this purpose, three electronic databases (Web of Science, PubMed, and Scopus) were searched using predetermined keywords. As a result of the screening, 25 studies were included in the review. The result of this systematic review focused on the methodology of applying cognitive tests and observed considerable heterogeneity in methodological procedures applied in studies investigating the cognitive performance of athletes. The findings of this review highlight the need for the development of standardized procedures for the assessment of cognitive performance in future research while offering practical recommendations for researchers and coaches working in this area.
