    Investigation of Foot Biomechanics in 5-15 Years Old Children Performing Gymnastics
    Seyhan, S; Açar, G; Yasasin, Y; Üzümcü, B; Sinen, H
    Gymnastics is a basic sport branch consisting of eight disciplines and is recommended to be taught to children at an early age. Our study aimed to evaluate the foot biomechanics and static plantar pressure of children aged 5-15 years who were performing rhythmic and artistic gymnastics. The study included 58 (19 Men/39 Women) child gymnasts and aged 5-15 years. Sociodemographic form, static plantar pressure analysis in bipedal position with pedobarography device, hallux valgus angle measurement (HVA), navicular drop test (NDT) and subtalar pronation angle measurement were performed respectively. The measurements were performed in the same way by an experienced expert. IBM Statistical Package for Social Sciences Version 26.0 (SPSS inc, Chicago, IL, USA) statistical programme was used. Tests were analyzed pairwise with Pearson correlation (p <= 0.05). The mean age was 7.43 +/- 2.37 years, height 124.68 +/- 16.97 cm, weight 27.39 +/- 11.39 kg and body mass index (BMI) 16.99 +/- 3.22 kg/m(2). There was no significant difference between weighted and unweighted in NDT results. In pedobarography analysis, hindfoot percentages were higher than forefoot percentages in static bipedal positions. A positive correlation was found between HVA and subtalar angles (p=0.00). In children performing artistic and rhythmic gymnastics, lateral ankle sprain may be observed due to a pronation tendency in subtalar angles. In addition, in the static bipedal position, distortions occurred in the bipedal static force center because the percentage of hindfoot pressure in plantar pressures was higher than the forefoot. Studies with foot-ankle exercises are needed for these.

    Super High-Intensity Continuous Training: A New Approach to Aerobic Training with Huge Effects on Elite Team Handball Players
    Milosevic, M; Dopsaj, M; Jourkesh, M; Milosevic, M; Seyhan, S
    The purpose of this study was to examine and evaluate the effectiveness of Super High-Intensity Continuous Training (SHCT) on elite team handball players. SHCT is a new approach of aerobic training that combines the advantages of both continuous and interval training methods. The study included 14 professional handball players who are members of the first national handball league team. The participants were trained five times a week over eight weeks using the SHCT method. The training intensity for each athlete was tailored to their individual oxygen consumption. Significant (P < 0.001) improvements were obtained in all measured and evaluated indicators of aerobic abilities, including maximal oxygen uptake (VO2max), maximum relative oxygen uptake (VO2rel), running speed at which maximum oxygen uptake occurs (VO2max), when comparing the pre-, intermediate, and post-tests, as well as a huge positive effect (eta(2)(G) reaching from 0.19 to 0.49 and eta(2)(p) of 0.91). These effects from short cycles of aerobic training have not been previously obtained in studies involving elite and and recreational athletes, whether using continuous or interval training approaches. In addition to the above,SHCT showed several other positive features. As such, we recommend further research into SHCT and encourage its integration into athletic training practices.

    Test-Retest Reliability and Validity of TecnoBody D-Wall to Assess the Range of Motion During Overhead Squat in Healthy Individuals
    Soylu, C; Acar, G; Uzumcu, B; Demir, P; Seyhan, S; Biyikli, T
    This study evaluated the validity and reliability of the TecnoBody D-Wall system in assessing joint range of motion (ROM) during overhead squat movements in healthy individuals, using Kinovea as a reference tool for data comparison. A total of 29 participants (16 males, 13 females) with a mean age of 28.41 +/- 6.66 years were included. Measurements were conducted for hip and knee joint angles in the sagittal plane, with three repetitions per participant analyzed using both systems. The D-Wall system employed a 3D Kinect V2 camera and force platform, while Kinovea used 2D video-based motion analysis. The results demonstrated excellent agreement between the two systems, with intra-class correlation coefficients (ICC) ranging from 0.79 to 0.99. For the knee joint, the test-retest ICC values were 0.99 (95% CI: 0.97-0.99) for Kinovea and 0.98 (95% CI: 0.95-0.99) for the D-Wall on the right side, and 0.98 (95% CI: 0.97-0.99) for Kinovea and 0.88 (95% CI: 0.79-0.94) for the D-Wall on the left side. For the hip joint, test-retest ICC values were 0.99 (95% CI: 0.97-0.99) for Kinovea and 0.94 (95% CI: 0.88-0.97) for the D-Wall on the right side, and 0.98 (95% CI: 0.97-0.99) for Kinovea and 0.93 (95% CI: 0.87-0.97) for the D-Wall on the left side. Bland-Altman plots confirmed good agreement, with no significant systematic bias observed. Both systems showed statistically insignificant differences (p > 0.05) between measurements, and correlation values ranged from 0.83 to 0.99, indicating strong associations. These findings highlight the high validity and reliability of both TecnoBody D-Wall and Kinovea systems in measuring joint angles during dynamic movements. The comparable accuracy between systems suggests that either system can be effectively utilized in clinical or research settings, depending on specific needs and resource availability.

    Selective Activation of the Infraspinatus During External Rotation Exercises in Participants with Rounded Shoulder Posture: Comparison of Three Common Exercises and Muscle Architecture-Based Exercise
    Soylu, C; Atalay, ES; Haksever, B; Demir, P; Seyhan, S; Biyikli, T
    Background and Objectives: The infraspinatus muscle is critical for shoulder stability and external rotation, yet achieving selective activation during exercises remains challenging. This study explores the effectiveness of a novel muscle architecture-based position (MABER) compared to traditional exercises in individuals with rounded shoulder posture. Materials and Methods: This prospective, cross-sectional study evaluated the selective activation of the infraspinatus during external rotation exercises in participants with rounded shoulder posture. Thirty-two participants (17 males and 15 females) were recruited. Electromyographic (EMG) activity of the middle trapezius, posterior deltoid, and infraspinatus muscles in the dominant limb was recorded during four exercise positions: standing external rotation (SER), side-lying external rotation (SDER), scapular plane external rotation (SPER), and MABER. Results: MABER produced the highest infraspinatus activity (p < 0.001), while the lowest activity was observed during SPER (p < 0.001). The SER position generated higher posterior deltoid activity compared to other positions (p < 0.001). The SDER position demonstrated the highest infraspinatus/posterior deltoid activity ratio (p < 0.001). Conclusions: The MABER position can be used as an effective exercise to strengthen the infraspinatus muscle. This study contributes to the literature by comparing MABER with traditional exercises and highlights its potential benefits for individuals with rounded shoulder posture.

    Seyhan, S; Saribas, GS; Akcay, NC; Gurgen, SG; Akyol, SN; Goktas, G; Hirfanoglu, IM; Erdogan, D; Ozogul, C
    Objective: The aim of the study was to investigate the prophylactic effects of acetyl L-carnitine against to uterus induced by cisplatin. Methods: Twenty-four female Wistar albino rats were divided into four groups: group I (control) was administered with saline; group II was administered with acetyl L-carnitine; group III was administered with cisplatin; group IV was pretreated with acetyl L-carnitine before cisplatin intraperitoneal injection. After 72h of cisplatin injection uterine tissue was removed. Histological and immunohistochemical investigations were performed, respectively. Results: We found that the number of TUNEL and caspases positive cells were increased in the endometrial epithelium, subepithelial connective tissue, endometrial glands and stroma in group III compare to the other groups. Furthermore inflammation and edema were observed in uterus of rats in group III. Conclusion: We can concluded that pretreatment of acetyl L-carnitine administration has protective effect on histological alteration of uterus caused by cisplatin.
