Öğe Cluster Set vs. Traditional Set in Plyometric Training: Effect on the Athletic Performance of Youth Football Players(Mdpi, 2025) Oztzurk, Bariscan; Adiguzel, Niyazi Sidki; Koc, Murat; Karacam, Aydin; Canli, Umut; Engin, Hakan; Orhan, Bekir ErhanAim: This study evaluated the effects of plyometric training with different set configurations on sprint speed, change of direction (COD), jump performance, and perceived exertion in youth football players. Method: Twenty-four U-19 players were randomized into three groups: Cluster Set (CLS, n = 8), Traditional Set (TRD, n = 8), and Control (CON, n = 8). CLS performed 8-10 sets of 2-3 repetitions, while TRD completed 2-3 sets of 8-10 repetitions in an 8-week plyometric program (2 sessions/week). The CON group did not train. Performance measures included 10 m, 20 m, and 30 m sprints, COD, Counter Movement Jump (CMJ), Reactive Strength Index (RSI), and Rate of Perceived Exertion (RPE). A repeated measures ANOVA analyzed group*time interactions. Results: Significant improvements were observed in CLS and TRD groups for sprints (10 m: f = 21.44; 20 m: f = 19.40; 30 m: f = 49.56; p < 0.001), COD (f = 14.66; p < 0.001), CMJ (f = 51.50; p < 0.001), and RSI (f = 24.91; p < 0.001). No changes occurred in CON (p > 0.05). Conclusions: CLS and TRD plyometric training improved sprint speed, COD, and jump performance, with CLS showing slightly superior results and better fatigue management.Öğe Finding Stability-A Case Report on the Benefits of Adapted Kata Training for Children with Autism Spectrum Disorder(Mdpi, 2024) Orhan, Bekir Erhan; Uzuncayir, Dilek; Canli, Umut; Karacam, Aydin; Ozdemir, Ali Selman; Popa, Cristian; Iconomescu, Teodora-MihaelaThis study investigated the efficacy of an Adapted Kata Training Program (AKTP) in enhancing balance for a 10-year-old child with Autism Spectrum Disorder (ASD), employing a mixed-model approach for data collection. Over 12 weeks, the AKTP demonstrated significant improvements in the child's balance abilities, with an 11% increase in static balance, 8% in proprioceptive, 12% in horizontal, and 14% in vertical balance performance. These improvements persisted in a follow-up assessment after four weeks. Observations by the child's mother corroborated the above findings. Consequently, this research suggests the AKTP as a valuable non-pharmacological intervention to improve balance in children with ASD. However, further studies are necessary to validate these results and explore the impact on additional developmental domains, such as cognitive and motor skills.Öğe Predicting functional movement capacity in adults: the effect of range of motion and isometric strength(Bmc, 2024) Ozkan, Mazhar; Canli, Umut; Alwhaibi, Reem; Ustamer, Kubra; Karacam, Aydin; Orhan, Bekir Erhan; Bohn, LucimereThe aim of the study was to determine the role of isometric strength and range of motion in predicting Functional Movement Screen (FMS) scores of adults. A total of 120 participants (age = 34.62 +/- 11.82 years; height = 170.56 +/- 9.63 cm; weight = 73.62 +/- 15.39 kg) volunteered to participate in the study. Anthropometric measurements were performed, including height, body weight, muscle mass, and body fat. Following this, the ranges of motion of the shoulder, hip, knee, and ankle joints were measured sequentially. Isometric strength and FMS tests were then performed. Hip extension isometric strength explained 23% of the variation in FMStotal. The common effect of knee flexion, shoulder flexion, and dorsiflexion joint range of motion explained 34% of the change in FMStotal (F ((3-116)) = 20.375, p < 0.001). A significant relationship (R = 0.658, R-2 = 0.413) was found between hip extension isometric strength, knee flexion, shoulder flexion, and dorsiflexion range of motion and FMStotal (F ((4-115)) = 21.952, p < 0.001). The common effect of all these variables explains 43% of the change in FMStotal. The results indicate that the FMS test scores, which are utilized to evaluate the risk of injury in sedentary adults, can be significantly predicted by the effect of hip extension isometric strength and parameters related to knee flexion, shoulder flexion, and dorsiflexion joint range of motion. At this time, it is advised that range of motion and isometric strength be taken into account when determining a person's functional movement capacity.Öğe The Effect of the Nordic Hamstring Curl Training Program on Athletic Performance in Young Football Players(Mdpi, 2024) Adiguzel, Niyazi Sidki; Koc, Murat; Ozturk, Bariscan; Engin, Hakan; Karacam, Aydin; Canli, Umut; Orhan, Bekir ErhanBackground: This study aimed to determine the effect of the Nordic hamstring curl training (NHCT) program on athletic performance elements such as linear speed, change of direction (COD), jump performance (CMJ), and eccentric muscle strength (Nordic Hamstring Curl Breaking Point Angle-NHCBP) in young football players. Methods: The study group consisted of 40 male football players who were actively trained and had no previous eccentric training experience or reported any injuries. The participants were randomly divided into a training group (TG = 20) and a control group (CG = 20). The TG performed the NHCT program twice a week for eight weeks, in addition to their standard football training. The CG continued with standard football training. Results: The study findings revealed no statistically significant differences in the interaction between group and time in 10, 20, and 30 m sprint performance. However, statistically significant differences were found in CMJ performance in terms of group-time interaction (F = 19.99, p < 0.001, eta(2) = 0.52), COD (F = 11.10, p < 0.004, eta(2) = 0.38), and NHCBP (F = 6.14; p < 0.02; eta(2) = 0.25). After the eight-week NHCT program, the experimental group showed improvements of 18% in CMJ performance, 8% in COD performance, and 25% in NHCBP performance. Conclusions: The NHCT program significantly increased hamstring muscle strength in football players, and this increase positively affected players' linear speed and change of direction performance. NHCT has the potential to enhance athletic performance in football.
