    (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 Acute Effects of Caffeine Supplementation on Anaerobic Performance and Functional Strength in Female Soccer Players
    (Mdpi, 2025) Mor, Hakki; Mor, Ahmet; Abdioglu, Mekki; Tohanean, Dragos Ioan; Savu, Catalin Vasile; Acar, Gizem Ceylan; Moraru, Cristina Elena
    Background/Objectives: Despite extensive research on caffeine's (CAF's) ergogenic effects, evidence regarding its impact on anaerobic performance in female athletes remains limited and inconclusive. The aim of this study was to investigate the acute effects of 6 mg/kg(-1) caffeine on anaerobic performance, functional strength, agility, and ball speed in female soccer players. Methods: A randomized, double-blind, placebo-controlled crossover design was employed. Thirteen moderately trained female soccer players (age: 21.08 +/- 1.11 years; height: 161.69 +/- 6.30 cm; weight: 59.69 +/- 10.52 kg; body mass index (BMI): 22.77 +/- 3.50 kg/m(2); training age: 7.77 +/- 1.16 years; habitual caffeine intake: 319 +/- 160 mg/day) completed two experimental trials (caffeine vs. placebo (PLA)), separated by at least 48 h. Testing sessions included performance assessments in vertical jump (VJ), running-based anaerobic sprint test (RAST), bilateral leg strength (LS), handgrip strength (HS), single hop for distance (SH), medial rotation (90 degrees) hop for distance (MRH), change of direction (COD), and ball speed. Rating of perceived exertion (RPE) was also recorded. Results: CAF ingestion significantly improved minimum (p = 0.011; d = 0.35) and average power (p = 0.007; d = 0.29) during RAST. A significant increase was also observed in SHR (single leg hop for distance right) performance (p = 0.045; d = 0.44). No significant differences were found in VJ, COD, ball speed, LS, HS, SHL, MRHR, or MRHL (p > 0.05). RPE showed a moderate effect size (d = 0.65) favoring the CAF condition, though not statistically significant (p = 0.110). Conclusions: In conclusion, acute CAF intake at a dose of 6 mg/kg(-1) may enhance anaerobic capacity and lower-limb functional strength in female soccer players, with no significant effects on jump height, agility, or upper-body strength.
