    (Mdpi, 2024) Acar, Kuersat; Mor, Ahmet; Mor, Hakki; Kargin, Zehra; Alexe, Dan Iulian; Abdioglu, Mekki; Karayigit, Raci
    Caffeine (CAF) has been shown to be an effective ergogenic aid in enhancing sports performance, including vertical jump (VJ), sprint, balance, agility, and freestyle swimming performance (FSP). However, whether acute CAF supplementation improves FSP in moderately trained female swimmers has not been well documented. Therefore, this study aimed to investigate the effects of CAF intake on vertical jump, balance, auditory reaction time (ART), and swimming performance in female swimmers. In a double-blind, cross-over design, eight moderately trained female swimmers (age: 21.3 +/- 1.4 years, height: 161.2 +/- 7.1 cm, body mass: 56.3 +/- 6.7 kg, body mass index (BMI): 21.9 +/- 1.3 kg/m(2), and habitual CAF intake: 246.4 +/- 111.4 mg/day) ingested caffeine (CAF) (6 mg/kg) or a placebo (PLA) 60 min before completing VJ, balance, ART, and 25/50 m FSP. CAF supplementation resulted in a significantly lower time both in 25m (p = 0.032) and 50m (p = 0.033) FSP. However, CAF resulted in no significant difference in VJ, ART, and RPE (p > 0.05). Balance test results showed a non-significant moderate main effect (d = 0.58). In conclusion, CAF seems to reduce time in short-distance swimming performances, which could be the determinant of success considering the total time of the race. Thus, we recommend coaches and practitioners incorporate CAF into swimmers' nutrition plans before competitions, which may meet the high performance demands.

    Moderate-dose caffeine enhances anaerobic performance without altering hydration status
    (Frontiers Media Sa, 2024) Mor, Ahmet; Acar, Kursat; Alexe, Dan Iulian; Mor, Hakki; Abdioglu, Mekki; Man, Maria Cristina; Karakas, Fatih
    The effects of direct nutritional supplements on athletic performance are still being investigated and arouse curiosity. Only one study in the literature was found that investigated the kicking speed performance of futsal players following low-dose caffeine supplementation (3 mg/kg); thus, the question of whether caffeine supplementation improves kicking speed as well as essential physical parameters in soccer players is still controversial. Therefore, the aim of this study was to determine the effect of caffeine supplementation on vertical jump (VJ), sprint, reaction time, balance, change of direction (COD), and ball-kicking speed in soccer players. In a double-blind, cross-over design, nine moderately trained male soccer players (21.11 +/- 2.02 years, 171.22 +/- 6.14 cm, 71.78 +/- 10.02 kg) consumed caffeine (6 mg/kg) or a placebo 60 min before completing balance, reaction time, vertical jump, agility, 30 m sprint, and ball-kicking speed tests. Greater VJ height (p = 0.01) and power (p = 0.08), and faster completion time according to the Illinois Agility Test (p = 0.08) were found following caffeine supplementation compared to placebo. Elapsed time (p = 0.01), average (p = 0.01) time, and the slowest reaction times (p = 0.016) were significantly reduced after caffeine consumption compared to placebo supplementation. Caffeine intake significantly improved VJ, agility, and reaction time (p < 0.05) but did not affect 30 m sprint, ball-kicking speed, balance, and RPE values in soccer players (p > 0.05). Although non-significant, caffeine intake also improved sprint (0.67%) and ball kicking (2.7%) performance percentages. Also, caffeine consumption did not induce dehydration, and the athletes' body hydration levels were normal. These findings support the use of caffeine supplementation as an effective nutritional ergogenic aid to enhance anaerobic performance, at least for vertical jumps, COD speed, and reaction time, in trained male soccer players.

    Prosocial and antisocial behaviors in Turkish female and male football players
    (Imr Press, 2022) Acar, Kursat; Mor, Hakki; KarakaS, Fatih; Yilmaz, Ali Kerim; Arslanoglu, Cansel; Mor, Ahmet
    Background and objective: Women have increasingly taken more part in a rather male-dominated sport in recent years: football, so our study's main focus is exploring the acts and behaviors of the female athletes during a football match. The study analyzes the sex-related differences in prosocial and antisocial behaviors between male and female athletes. Materials and methods: A total of 837 players, recruited from various leagues in Turkey, participated in the study. Participants were active female (n = 432) and male (n = 405) football players. The informed consent form and Prosocial and Antisocial Behavior in Sport Scale (PABSS) were utilized as data collection tools. Results: Female football players displayed less prosocial and more antisocial behaviors compared to male football players. Among all the league statuses, both female and male players exhibited the highest prosocial and the lowest antisocial behaviors in the top league status. Additionally, there were statistically significant differences concerning the age variable (p < 0.05). Conclusions: Our study findings indicate that male football players engaged in more prosocial behaviors toward both their teammates and opponents than female football players; moreover, male players engaged in less antisocial behaviors in general. Players reported higher prosocial and lower antisocial behavior scores as league status increased. Lastly, higher prosocial behavior scores were obtained with increasing age.

    THE EFFECTS OF DIFFERENT WARM-UP PROTOCOLS ON SOME PERFORMANCE PARAMETERS IN 11-12 AGE GROUP FOOTBALL PLAYERS
    (Ankara Üniversitesi, 2021) Mor, Ahmet; Yurtseven, Rifat; Mor, Hakki; Acar, Kürsat
    The aim of this study was to investigate the effects of two different warm-up protocols on some performance parameters in 11-12 age group football players and analyze the correlation. Active and trained 22 male football players (age: 11.50±.51 years; height: 148.54±7.69 cm; weight: 40.44±7.50 kg and body mass index (BMI): 18.21±2.29 kg/m2) voluntarily participated in this study. Subjects performed two different warm-up protocols including jogging+dynamic stretching and jogging+static stretching exercises on non-consecutive days. Following the dynamic and static warm-up protocols and then three minutes of passive recovery, subjects were tested on the leg power, flamingo balance test, T-test, 30-m sprint and ball kicking speed. Data were checked for normality by using Shapiro-Wilk test. Mann-Whitney U test was used for comparing the effect of warm-up methods on selected performance parameters. Correlation between parameters were analyzed with Spearman Correlation test. There was statistically significant difference (p<0.05) between dynamic and static warm-up methods in T-test, while no statistical significance existed in other performance results (p>0.05). According to the results of this study, dynamic warm-up protocol provides performance enhancement, although agility is the only parameter reached statistical significance, in leg power, balance, agility, sprint and ball kicking speed compared to static warm up protocol, and it is thought to have positive effects in football players when performed prior to the training. So, dynamic stretching exercises before training in football players are strongly recommended for performance enhancement. On the other hand, football is characterized by variety of the physical-physiological demands and performance parameters, so it can be said that warm-up protocol preference is very crucial and it may vary by training requirements.
