  Eroglu, Seref; Toktas, Sermet; Çaglar, Esin Cagla; Ünlü, Cisem; ÇevIker, Abdulkerim; Zambak, Omer

  The goal of this study was to compare the tactics expertise paradigms and game-reading skills of elite football coaches with different geographical and cultural back-grounds, based on empirical data. In total, ten elite football coaches participated in the study. All participants had at least 10 years of coaching experience and had either UEFA Pro or A license. Coaches came from the following football federations: Scandinavian (n = 4) , Baltic (n = 3) , and Turkish (n = 3) In order to gather empirical data regarding the knowledge of coaches about theory and methods in cri-sis situation (tacit knowledge), we used the interview form comprising of 25 ques-tions. The Kruskal-Wallis H test results indicated significant differences between groups (p < 0.05) in all aspects of tacti-cal expertise paradigm examined: strate-gic planning, offensive organization, de-fensive transitions, crisis management, and methodological fidelity. Effect sizes calcu-lated for each aspect proved that the mem-bership of the coaches' group (geographi-cal and cultural school) accounted for sig-nificant percentage of variance in their tac-tical expertise (n(2) = 0.777 - 0.86) The results obtained showed that Scandinavian School of coaching prioritized struc-tural discipline and collective intelligence principles, obtaining the highest ratings in strategic planning (4.43) and method-ological fidelity (4.77). Turkish School demonstrated its advantage in crisis man-agement (4.59); however, Turkish coaches were characterized by the lowest rate in methodological fidelity (2.94). As the re-sult, ability of Turkish coaches in tactical improvisation and intuitive expertise con-flicts with system-oriented approach. De-spite obtaining the best score in defen-sive transitions (4.76), the Baltic School demonstrated its reactivity in regards to offensive organization and strategic plan-ning. To conclude, this study showed that tactical expertise is not only a set of tech-nical knowledge, but also the specific cog-nitive scheme that includes geographic and cultural code elements. It can be concluded that distinctive feature of Scandinavian ra-tionalism and Turkish dynamism provides useful theoretical background for hybrid coach models in contemporary football.

  Selmi, Mohamed Amin; Hammami, Raouf; Ceylan, Halil Ibrahim; Duncan, Michael; Sassi, Radhouane Haj; Morgans, Ryland; Bayrakdaroglu, Serdar; Bragazzi, Nicola Luigi

  High-intensity interval training (HIIT) and repeated-sprint sets (RSS) are established conditioning methods in soccer, yet their integration with plyometric training among highly trained youth soccer players remains underexplored. This study investigated the effects of an 8-week program combining plyometric training with either RSS (PLYO-RSS) or HIIT (PLYO-HIIT) on physical fitness in young soccer players. Twenty-nine male players (14-15 years) were randomly assigned to PLYO-RSS (n = 14) or PLYO-HIIT (n = 15). Both interventions lasted 20 minutes per session and replaced part of regular soccer training. Physical fitness assessments included countermovement jump (CMJ), 15-s repeated vertical jumps (15''RJ), five-jump test (5JT), 10 m and 30 m sprint, maximal aerobic speed (MAS), VO2max, and repeated sprint performance (total sprint time, best sprint, fatigue index). Physiological markers (lactate, rating of perceived exertion, and HRmax) were also monitored. Significant improvements over time were observed in muscle power, sprint speed, aerobic capacity, and repeated-sprint ability (p <= 0.001; eta & sup2;p = 0.339-0.489). However, no main effects or group & times; time interaction effects were observed, indicating no evidence of differential responses between the two training modes. In conclusion, integrating plyometric training with either RSS or HIIT effectively enhances physical fitness in highly trained youth soccer players, offering flexible options for training prescription.

  Match success in football: insights from raw and possession-normalized key performance indicators in the Turkish professional league

  Sever, Ozan; Öncü, Çağdaş; Öztaşyonar, Yunus; Aksoy, Ömer; Bayrakdaroğlu, Serdar

  Background: Match-performance indicators are widely used to explain success in football; however, traditional analyses based solely on absolute key performance indicators (KPIs) may overlook contextual factors such as ball possession and phase of play. This study aimed to examine match-performance indicators associated with winning in Turkish professional football using two complementary approaches: a raw KPI model based on absolute match actions and a possession- and phase-of-play–normalized KPI model accounting for contextual opportunity. Methodology: Match data were obtained from a validated event-based database covering six consecutive seasons, yielding 2,728 team observations from 1,364 win–loss matches. Descriptive comparisons between winning and losing teams were conducted, followed by multivariate binary logistic regression analyses to identify performance indicators independently associated with match success under both modeling approaches. Results: At the descriptive level, winning teams demonstrated higher values for shots, shots on target, accurate passes, opponent-half accurate passes, accurate crosses (%), and opponent-half accurate passes (%), whereas total possession and total passes did not differ significantly between groups. In terms of disciplinary indicators, losing teams received significantly more yellow and red cards, whereas fouls committed were significantly higher in winning teams (p = 0.014). However, the normalized indicator (fouls committed per out-of-possession) did not differ significantly between groups. In the raw KPI model, positive predictors of match success included shots on target (OR = 1.58), accurate crosses (OR = 1.10), opponent-half accurate passes (OR = 1.01), and fouls committed (OR = 1.04). Negative predictors were total crosses (OR = 0.92), yellow cards (OR = 0.89), and red cards (OR = 0.49). In the possession-normalized model, significant positive predictors were shots on target per possession, accurate crosses per possession, and fouls committed per out-of-possession. Significant negative predictors included crosses per possession, accurate crosses (%), yellow cards per out-of-possession, and red cards per out-of-possession. Conclusions: The findings indicate that combining absolute performance indicators with context-sensitive normalized metrics may provide a more comprehensive perspective on match success in football. Offensive efficiency and disciplinary control emerged as key correlates of winning, particularly when evaluated relative to possession and phase-of-play contexts. These findings suggest the potential value of integrating contextualized performance analysis into match evaluation and performance analysis frameworks.

  Kartal, Alper; Ilhan, Muhammet Taha; Ergin, Esin; Pancar, Zarife; Karaca, Burak; Yildiz, Yasin; Gulsen, Doğukan Batur Alp; Bayrakdaroğlu, Serdar

  The post-activation performance enhancement (PAPE) effect has been widely studied; however, studies conducted under real-world conditions remain limited. Furthermore, investigations into how different conditioning activities (CAs) influence PAPE responses are also scarce. Therefore, this study investigates the acute effects of high-intensity barbell hip thrust (BHT) and back squat (BS) exercises, performed after a soccer-specific warm-up (Wup), on physical performance in soccer players. Seventeen male amateur soccer players participated in the study (mean age: 22.29 ± 3.60 years; height: 1.78 ± 0.06 m; body weight: 73.18 ± 8.44 kg). Participants attended 5 experimental sessions. In the first session, after anthropometric assessments, participants were familiarized with the exercises and tests. In the second session, one-repetition maximum (1RM) was tested for BS and HT exercises. In the following three sessions, two PAPE protocols and one traditional (TRAD) protocol were performed in a randomized order. In the TRAD protocol, players performed physical performance tests including countermovement jump (CMJ), 10-m and 30-m sprint, and zigzag agility 16 minutes after a soccer-specific Wup. In the PAPE protocols, players performed CAs (e.g., hip thrust or back squat) at 85% of 1RM for 2 sets of 3 repetitions following a soccer-specific Wup, and completed the tests 8 minutes later. Results from the linear mixed-effects models revealed no significant effect of protocol on any performance variable, including CMJ (F(2,32) = 1.554, p = 0.227), 10 m sprint (F(2,32) = 0.242, p = 0.786), 30 m sprint (F(2,32) = 0.453, p = 0.640), and change of direction (COD) performance (F(2,32) = 0.946, p = 0.399). Marginal R² values indicated that the protocol explained only a minimal proportion of variance in performance outcomes (0.005–0.030), whereas conditional R² and ICC values suggested that between-participant differences accounted for a substantial proportion of variance, particularly for CMJ and 30 m sprint performance. Bonferroni-adjusted pairwise comparisons further showed no significant differences between PAPEBHT, PAPEBS, and TRAD protocols for CMJ, 10 m sprint, 30 m sprint, or COD performance (all p > 0.05). In conclusion, neither PAPE protocol performed after a soccer-specific warm-up significantly enhanced or impaired subsequent CMJ, sprint, or COD performance compared with the traditional warm-up. These findings suggest that adding PAPEBHT or PAPEBS protocols after a soccer-specific warm-up may maintain subsequent performance without inducing measurable decrements; however, their ergogenic effectiveness may depend on individual factors such as players’ strength levels, recovery capacity, training status, and physical characteristics.

  Exploring the acute recovery effects of dry cupping therapy and electrical stimulation on anaerobic performance metrics in active individuals: A quasi-experimental crossover study

  Can, Ibrahim; Yerlikaya, Gokhan; Yalçin, Seda; Bayrakdaroglu, Serdar; Kayhan, Recep Fatih; Uluç, Ender Ali; Stefanica, Valentina; Ceylan, Halil Ibrahim

  Background:This quasi-experimental crossover study aimed to examine the acute effects of dry cupping therapy (DCT) and neuromuscular electrical stimulation (NMES) on fatigue and perceived exertion in anaerobic performance among physically active individuals.Methods:Twelve male participants (mean age: 24.1 +/- 2.37 years), all students from the Faculty of Sports Sciences, were recruited to participate voluntarily. Anaerobic performance parameters, including peak power, mean power (MP), and fatigue index (FI), were assessed using a Monark 839E cycling ergometer under 3 distinct conditions: NMES, DCT, and a control condition (no intervention), with each session separated by a 48-hour rest period. Perceived exertion was evaluated immediately following each test session using Borg's rate of perceived exertion (RPE) scale. Both NMES and DCT were administered bilaterally to the hamstring (m. hamstring) and quadriceps femoris (m. quadriceps femoris) muscles for 20 minutes before testing.Results:The results revealed no statistically significant differences in peak power and MP across the conditions. However, significant effects were identified for FI (F(2, 22) = 4.08, P = .031, eta p(2) = 0.27) and RPE (F(2, 22] = 8.88, P = .0015, eta p(2) = 0.45). Post hoc pairwise comparisons indicated that NMES significantly reduced FI compared to the control condition (P = .0311), with a small to medium effect size (Cohen's d = 0.44). In terms of RPE, DCT significantly lowered values compared to both the control (P = .0018) and NMES conditions (P = .0005), demonstrating medium (Cohen's d = 0.74) and small to medium (Cohen's d = 0.37) effect sizes, respectively.Conclusions:While NMES and DCT did not elicit acute improvements in peak or mean anaerobic power, both interventions effectively mitigated fatigue and reduced perceived exertion during maximal anaerobic exercise. These findings suggest that NMES and DCT may serve as valuable recovery modalities for mitigating fatigue in sports characterized by high anaerobic demands. Future research should investigate the chronic effects of these interventions and explore their utility among trained athletes to determine their broader applicability in enhancing athletic performance.

  The acute effect of neuromuscular electrical stimulation on optimum power performance in healthy individuals

  Can, Ibrahim; Yerlikaya, Gokhan; Bayrakdaroglu, Serdar; Ceylan, Halil Ibrahim; Subak, Guelhan Erdem; Bayrakdaroglu, Yesim; Uluç, Sinem; Nikolaidis, Pantelis T.

  Background: This study examines the acute effects of neuromuscular electrical stimulation (NMES) application on peak power (PP) and mean propulsive power (MPP) during a weighted squat jump (SJ(Loaded)). Methods: Fourteen male students (age: 23.71 +/- 2.30 years; height: 173.71 +/- 6.89 cm; weight: 69.59 +/- 9.08 kg; body mass index (BMI): 26.87 +/- 3.49) from the Faculty of Sport Sciences participated voluntarily. PP and MPP values were measured during the SJ(Loaded) movement, performed with an external load of 40% body weight, using a computer-integrated linear velocity transducer system (T-Force Dynamic Measurement System Ergotech Consulting SL, Murcia, Spain). NMES was bilaterally applied to the musculus hamstring and musculus quadriceps femoris for 20 minutes. The Shapiro-Wilk test, skewness and kurtosis values assessed data normality. Results: Differences between pre- and post-test PP and MPP power performances were analyzed using Paired Samples t-tests. Cohen's d (ES: effect size) and 95% confidence intervals (CI) were also calculated to assess the pairwise comparisons' magnitude. According to the analysis results, statistically significant improvements were observed in both PP (t (13) = -2.612, p = 0.021, d: -0.69 (-1.27; -0.10, 95% CI)) and MPP (t (13) = -2.756, p = 0.016, d: -0.73 (-1.32; -0.13, 95% CI), moderate effect) values after the NMES application. Conclusions: NMES significantly enhances PP and MPP during loaded squat jumps, highlighting its potential as a supplementary training tool for improving explosive power. Future studies should explore its long-term effects across different sports and populations, such as female athletes or older adults, to optimize training protocols. Research on NMES intensities and frequencies may provide insights into optimal parameters for power development and neuromuscular adaptation.

  The Effects of Vertıcal and Horızontal Statıc Core Strength Exercıses on Athletıc Performance ın Young Female Handball Players

  Bayrakdaroğlu, Serdar; Ceylan, Halil Ibrahim; Edis, Çağlar

  Core exercises are typically performed in the horizontal plane, whereas athletic activities such as running, jumping, and change of direction (COD) occur in both vertical and horizontal planes. This study aimed to investigate the effects of static core exercises performed in the vertical and horizontal planes on physical performance. Twenty-four female handball players voluntarily participated in the study and were randomly assigned to either a vertical static core (VSC) exercise group (n=12; age: 17,75±0,99 years, height: 171,00±8,66 cm, weight: 66,08±5,97 kg) or a horizontal static core (HSC) exercise group (n=12; age: 17,75±0,75 years, height: 166,75±13,71 cm, weight: 63,33±6,74 kg). A two-group experimental design with a pretest-posttest model was employed. The core exercise protocol consisted of prone plank, side plank (right and left), supine bridge, and bird dog exercises, performed three times per week for eight weeks. Before and after the intervention, participants were evaluated for isometric core strength, 5-20 meter linear sprint performance, vertical jump height, and three different COD performance tests. Data were analyzed using the Shapiro-Wilk test to assess the normality of the distribution. Paired samples t-tests were used to analyze differences between the groups’ pretest and posttest results based on normality assumptions. For between-group comparisons, independent samples t-test was used. The results revealed no statistically significant differences between the VSC and HSC groups in terms of post-exercise performance improvements (p>0.05). However, significant improvements in physical performance parameters were observed within both groups from pre- to post-intervention (p

  ACTN3, IL-6 AND PPARA GENE POLYMORPHISMS AND ANAEROBIC PERFORMANCE IN VOLLEYBALL PLAYERS

  Ön, Sadi; Can, Ibrahim; Bayrakdaroglu, Serdar; Sever, Mehmet Onur; Diker, Gurkan; Özkamçi, Huseyin; Zileli, Raif; Söyler, Mehmet; Yilmaz, Ozlem Ozge; Polat, Tolga

  The aim of this study is to determine the relationship between ACTN3 rs1815739, IL-6 rs1800795, and PPARA rs4253778 gene polymorphisms and anaerobic test parameters among volleyball players. A total of 22 volleyball players voluntarily participated in the study. DNA isolation from buccal epithelial cell samples were performed using a PureLink DNA isolation kit, following the manufacturer's instructions. The genotyping of ACTN3 rs1815739, IL-6 rs1800795, and PPARA rs4253778 gene polymorphisms were determined using the real-time polymerase chain reaction technique. Statistical analysis of the test results was performed using the SPSS 23 software package. Homogeneity of variance was assessed with the Levene test, and normal distribution was evaluated using the Shapiro-Wilk test. The One-Way ANOVA test was applied for the analysis of all parameters, and significance was set at p < 0.05. When the data were evaluated, no statistically significant differences were observed between PPARA rs4253778 and ACTN3 rs1815739 gene polymorphisms and anaerobic performance parameters (p>0.05). Statistically significant differences were observed between the IL-6 rs1800795 gene polymorphism and anaerobic performance parameters of back strength (p> 0.05). In conclusion, in volleyball, PPARA rs4253778 andACTN3 rs1815739 gene polymorphisms did not cause differentiation in anaerobic performance parameters. However, IL-6 gene polymorphism caused differentiation only in the back strength parameter. Additionally, the good performance of athletes with different prevalent level of genotypes in the studied performance criteria does not fully reveal which performance outcomes are influenced by the gene or genotype distributions. It is understood that further studies are needed to better determine the gene-performance relationship.

  Isometric Shoulder and Hip Strength Impact on Throwing Velocity and Reactive Strength

  Kayhan, Recep Fatih; Terzi, Esranur; Bayrakdaroglu, Serdar; Ceylan, Halil Ibrahim; Biyikli, Turker

  The aim of the study is to examine relationships between shoulder extension-flexion and internal-external rotation strength of professional male handball players with throwing velocity, and the hip extension-flexion strength with horizontal and vertical reactive strength index. Fifteen professional male handball players participating in 1 st League matches took part in the study. The results showed that isometric shoulder flexion and extension strength significantly predicted stable throwing velocity (r (2 )=between 0.27-0.73) and dynamic throwing velocity (r( 2) =between 0.30-0.62). In addition, isometric internal and external rotation strength significantly predicted stable throwing velocity (r (2) =between 0.32-0.54) and dynamic throwing velocity (r (2) =between 0.31-0.44). Moreover, isometric hip extension and flexion strength significantly predicted vertical reactive strength index (r( 2) =between 0.31-0.45) and horizontal reactive strength index (r (2) =between 0.26-0.42). In conclusion, it was observed that shoulder strength has an enhancing effect on handball players' throwing velocity, while hip strength is a determining factor for the reactive strength index. In this context, it is assumed that shoulder weakness during throwing will affect the accuracy and velocity of throwing by disrupting the angular momentum, while weakness in the hip during the jump phase of the throwing motion will negatively affect the explosive power by limiting stabilization during landing.
