    (MRE PRESS, 2025) Kırıkoğlu, N; Pekel, AÖ; Ceylan, T; Eliöz, M; Yavaşoğlu, B; Beykümül, A; Kurt, KA; Çalışan, HY; Baykal, C; Karaman, M; Türkoğlu, H; Ceylan, L
    Background: In this study, the Rsscan V9 (RsScan International, Olen, Bel & ccedil;ika) foot scanning system was used to determine the potential foot pressure distribution and foot contact times of individuals in early adolescence who did not receive sports training and those who received regular basketball training. Methods: The study involved 120 adolescent volunteers aged 11-14 years of which 60 did not receive sports training, and the other 60 received basketball training in Ankara for at least two years. The sociodemographic data of the study participants were documented. The foot pressure analyses were carried out in both fixed and moving postures. Results: When pressure values were compared between adolescents with and without basketball training, statistically significant differences were found between Q1 (left forefoot pressure) and Q2 (right forefoot pressure) values. Specifically the mean value (p < 0.05) of Q2 (right forefoot pressure) variable was higher in basketball participants compared to non-athletes. In non-athletes, Q1 (left forefoot pressure) (p < 0.05) was significantly higher than in participants who received basketball training. Similarly, with regard to the left forefoot pressure duration (left ms) variable, participants with basketball training showed significantly higher mean scores than non-athletes (p < 0.001). The findings revealed that there were differences in pressure imbalances and ground contact times between basketball players and non-players. Conclusions: If not controlled regularly, pressure imbalances can lead to serious discomfort in the feet, knees, hips and lower back, and serious injuries can be prevented if detected early. Minor injuries that develop due to repetitive movements and stress on joints from years of training can be treated early, and preventive applications can becarried out by recognising potential injuries. For this reason, it is recommended that basketball players have a regular foot pressure analysis carried out at the start of the season.

    Effects of inspiratory muscle training on 1RM performance and body composition in professional natural bodybuilders
    (FRONTIERS MEDIA SA, 2025) Çelikel, BE; Yılmaz, C; Demir, A; Sezer, SY; Ceylan, L; Ceylan, T; Tan, ÇT
    Background The effect of inspiratory muscle training on upper limbs One Rep Maximum (1RM) in professional natural bodybuilders is still unclear. Our aim of this study is to investigate the effects of a 6 weeks inspiratory muscle training on 1RM results.Methods This study included 14 athletes, that had participated in international bodybuilding competitions. Each athlete had been training for minimum of 5 years and at least 5 h per week. The participants were randomly divided into two groups: inspiratory muscle training (IMT) and control (CON) groups. The IMT group and CON group consisted of seven subjects. While the control group continued with the normal training regime, the IMT group additionally performed inspiratory muscle training with the resistance setting of the PowerBreathe (R) Classic device set to 40% of the participant's MIP. Prior to and during the 6-week training period, the bench press 1 RM, anthropometry, pulmonary function tests, and maximal inspiratory (MIP) and expiratory (MEP) pressure measurements were obtained. A nutrition protocol developed by a qualified dietician was implemented for each athlete.Results The mean maximal strength of the respiratory muscle training group changed by 14.39%, whereas that of the control group changed by 9.43% (p = 0.012). The changes in the mean FVC (p = 0.000), FEV1 (p = 0.001), PEF (p = 0.064), MIP (p = 0.001), and maximal expiratory pressure (p = 0.017) were greater in the IMT group. The mean circumferences of the shoulder (p = 0.004), chest (p = 0.008), arm (p = 0.004), and neck (p = 0.003) improved more in the IMT group than in the CON group. A reduction in abdominal measurement was observed in the IMT group (p = 0.039), whereas no notable discrepancy was identified in body fat percentage (p = 0.295).Conclusion In conclusion we identified that the addition of progressive loading inspiratory muscle training for competition preparation programs in professional natural bodybuilders will further improve their respiratory function, respiratory muscle strength, maximal strength, and muscle development. This research provides valuable insights into how IMT influences bodybuilding training outcomes, potentially guiding future interventions and program designs to better support strength development and body composition in bodybuilding training contexts.

    (FRONTIERS MEDIA SA, 2025) Yamaner, E; Turgut, T; Aksoy, A; Demirkıran, B; Uçar, MA; Başoğlu, B; Çamiçi, F; Yanar, MS; Bülbül, A; Koç, AF; Ceylan, T; Ceylan, L; Küçük, H
    Background A physically inactive lifestyle is associated with an increased risk of obesity, dyslipidemia and metabolic disorders, especially in women. While high-intensity training methods have been extensively studied in male populations, the physiological and metabolic effects of high-intensity interval resistance training (HIIRT) in overweight women are understudied. The aim of this study was to investigate the effects of an 8-week HIIRT program on body composition and lipid metabolism in women.Methods A total of 30 women (mean age: 23.13 +/- 4.03 years, mean BMI: 31.21 +/- 2.92 kg/m2) participated in an 8-week HIIRT program. Body composition was measured before and after the intervention using bioelectrical impedance analysis (BIA), while blood lipid parameters (triglycerides, total cholesterol, LDL, and HDL) were analyzed. Paired-sample t-tests were performed to determine the significance of the changes in body composition and lipid metabolism, using Cohen's d effect size for interpretation.Results The HIIRT program led to significant improvements in body composition, with body weight decreasing by 11.4 kg (p = 0.001, d = 0.96) and fat percentage decreasing by 3.1% (p = 0.001, d = 0.92). In addition, blood lipid profiles improved significantly, with triglycerides (-8.9 mg/dL, p = 0.001, d = 0.81, medium effect), total cholesterol (-19.7 mg/dL, p = 0,020, d = 1.98, large effect), and LDL (-8.2 mg/dL, p = 0.004, d = 1.96, large effect) decreased, while HDL increased by +10 mg/dL (p = 0.006, d >= 2.0, very large effect). These results underline the positive effects of HIIRT on lipid metabolism and cardiovascular health.Conclusion The results suggest that HIIRT is an effective and time-efficient training model for improving body composition and metabolic health in women. The combination of high-intensity interval training principles with resistance exercise optimizes fat oxidation, improves fat metabolism and supports cardiovascular function. Given its efficacy, HIIRT could be a valuable strategy for treating metabolic disorders and reducing the risks of physically inactive behavior. Future research should focus on long-term adaptations and individual variability in metabolic responses to optimize HIIRT programs for broader populations.

    (FRONTIERS MEDIA SA, 2025) Kaba, İ; Çelikel, BE; Adanur, O; Yılmaz, C; Sezer, SY; Tan, Ç; Durhan, TA; Özer, U; Ceylan, T
    Background A limited number of studies have investigated the effects of circadian rhythm-based running exercise interventions on physical fitness in child athletes. This study aimed to investigate the effects of an eight-week morning and evening running program on lower extremity strength, agility and respiratory function in 10-12-year-old male footballers.Methods Participants visited the laboratory three times, with one-day intervals before and after the training program. The assessments included maximal inspiratory pressure (MIP), maximal expiratory pressure (MEP), forced expiratory volume in one second (FEV1), forced vital capacity (FVC), and the FEV1/FVC ratio. Additionally, agility and functional performance tests (FPTs) were conducted for both the dominant and non-dominant legs.Results The findings indicated that morning running was more effective than evening running in enhancing respiratory function. Morning running also showed superior results in lower extremity strength tests, particularly in the single-leg (SL) and triple-leg (THD) crossover hop for distance tests (CHDs) and the 6-m timed-hop test (6 m THT). Furthermore, the agility performance of the morning running group was significantly better than that of the evening and control groups.Conclusion Consequently, morning running interventions had a positive impact on key physical fitness parameters, including respiratory muscle strength, respiratory function, agility, and lower extremity strength in child footballers.

    (FRONTIERS MEDIA SA, 2025) Küçük, H; Ghadamyari, N; Şahin, FN; Çiçek, G; Ceylan, T; Güler, O; Yaşar, OM; Şensoy, C; Arslanoğlu, C; Doğan, E; Arslanoğlu, E
    Background: Knee osteoarthritis (KOA) is a prevalent chronic condition among the adult individuals, leading to pain, joint stiffness, and muscle weakness. Resistance training is an effective strategy for alleviating KOA-related symptoms and improving physical function. However, the efficacy of such interventions also depends on their fidelity, ensuring that the prescribed exercise protocols are followed correctly. This study aimed to assess the fidelity of a structured strength training program and its effects on pain management in adult individuals with KOA. Methods: A total of 72 adults (mean age = 56.27 +/- 4.89 years), approximately 40% of whom were overweight, were randomly assigned to either a strength training group (n = 37) or a control group (n = 35). Quantitative data were collected using the Knee Injury and Osteoarthritis Outcome Score (KOOS), while qualitative data on intervention fidelity were obtained through self-reported adherence to daily home workouts. Results: The results indicated a significant improvement in KOOS scores in the strength training group compared to the control group (p < 0.001). Participants consistently adhere to the prescribed exercise program in their home workouts. These findings highlight the importance of intervention fidelity in strength training programs for adult individuals with KOA, emphasizing its role in optimizing health outcomes. Conclusion: This study contributes to the growing evidence supporting structured strength training as a viable strategy for managing KOA-related symptoms and enhancing physical function in ageing populations.

    Synthesis and Characterization of Rosa Canina-Fe3O4/Chitosan Nanocomposite and Treatment of Safranin O Dye from Wastewater
    (MDPI, 2025) Ceylan, T; Satır, İT; Akmeşe, B
    In response to the increasing demand for environmentally friendly and cost-effective adsorbents in wastewater treatment, this study reports the green synthesis, characterization, and application of a magnetic epichlorohydrin Rosa canina (m-ECH-RC) nanocomposite for removing Safranin O (SO), a commonly used cationic dye in textile effluents. The synthesized material was characterized using Brunauer-Emmett-Teller (BET), Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), X-ray diffraction (XRD), and zeta potential analyses to reveal its surface morphology, pore structure, functional groups, crystallinity, and colloidal stability. Adsorption performance was systematically tested under various conditions, including pH, adsorbent dose, contact time, ionic strength, and initial dye concentration. Kinetic analyses revealed that the adsorption process of Safranin O dye mainly obeys pseudo-second-order kinetics, but intraparticle and film diffusion also contribute to the process. As a result of the Isotherm analysis, it was found that the adsorption process conformed to the Langmuir model. Testing on real textile wastewater samples demonstrated a removal efficiency of 75.09% under optimized conditions. Reusability experiments further revealed that the material maintained high adsorption-desorption performance for up to five cycles, emphasizing its potential for practical use. These findings suggest that m-ECH-RC is a viable and sustainable adsorbent for treating dye-laden industrial effluents.

    (FRONTIERS MEDIA SA, 2025) Bingöl, M; Ünver, S; Mor, H; Berk, Y; Ceylan, T; Derebaşı, DG; Aydın, YN; Akman, T; Küçük, H; Ceylan, L
    Background:Regular training is associated with better postural alignment, decreased risk of musculoskeletal problems, and improved overall physical function. The aim of this study was to examine the changes in the spinal postures of individuals who regularly engage in fitness and bodybuilding training. Methods; A total of 252 male individuals between the ages of 20-28 (mean age: 23.71 +/- 1.81 years), who either engage in fitness and bodybuilding training (athletes) (n = 125; age 23.61 +/- 1.78 years; sports age 5 +/- 0.89 years) and those who do not engage in sports (sedentary) (n = 127; age 23.82 +/- 1.83 years) participated in the study. A spinal Mouse device was used in the measurements. In spine measurement, all spinal protrusions from C7 to S1 were evaluated. T-test and correlation tests were used to analyze the data. Results:A statistically significant difference was detected between the athlete and sedentary groups regarding the degrees of thoracic kyphosis, lumbar lordosis, and sacral kyphosis (p < 0.05). However, no difference was observed in the upright posture (p > 0.05). Conclusion: It was found that there were significant differences in some spinal curves of fitness and bodybuilding trainees compared to sedentary, but the values were within physiological limits and did not indicate negative effects. The study may provide new insights into the effects of fitness and bodybuilding training on spine health, and individuals can incorporate training with proper form and technique into their lifestyle for spinal health.
