Öğe Can polycythaemia vera disease be predicted from haematologic parameters? A machine learning-based study(Bmj Publishing Group, 2025) Haskul, Murat; Kaya, Emin; Kurtoglu, AhmetAims The aim of this research is to diagnose polycythaemia vera (PV) disease using different machine learning (ML) algorithms with complete blood count (CBC) parameters before further investigations such as Janus kinase 2 (JAK2), erythropoietin (EPO) and bone marrow biopsy (BMB). Methods The study included 1484 patients who presented to the adult haematology clinic with elevated haemoglobin. Participants were retrospectively screened for JAK2, EPO and BMB results, and patients were categorised as PV group (n=82) and non-PV (other) (n=1402). First, the synthetic minority oversampling technique (SMOTE) method was used to avoid data imbalance. Then, classification predictions were made using Random Forest, Support Vector Machine Technique, Extreme Gradient Boosting (XGBoost) and K-Nearest Neighbours algorithms according to the participants' CBC parameters of white cell count (WBC), haematocrit (HCT), haemoglobin (HGB) and platelet (PLT). Results The XGBoost algorithm was found to be the most effective ML algorithm in predicting the model (area under the curve=0.99, accuracy=0.94, F1-Score=0.94). In addition, the most effective parameter in the prediction of the model was PLT with 42.4%. As a result of the t-test, there was a highly significant difference between the WBC, PLT, HGB, HCT, EPO, JAK2 and bone marrow density results of PV and other groups (p<0.001). Conclusion ML algorithms can diagnose PV with CBC parameters with high accuracy, thus emphasising the potential to reduce the dependence on costly diagnostic methods such as JAK2, EPO and BMB.Öğe Chronotype as a predictor of athletic performance in youth with mild intellectual disabilities(Frontiers Media Sa, 2024) Kurtoglu, Ahmet; Eken, Ozgur; Tuerkmen, Musa; Car, Bekir; Setiawan, Edi; Yermakhanov, Baglan; Alotaibi, Madawi H.Aim This study aimed to explore the influence of circadian rhythms on athletic performance in individuals with mild intellectual disabilities (ID), with a specific focus on elucidating the association between chronotype and various performance metrics. Methods The study was a cross-sectional study consisting of 30 male participants aged between 11 and 19 years and diagnosed with mild ID. The chronotypes of all participants were assessed using the Childhood Chronotype Questionnaire (CCQ). Performance assessments were divided into three groups. Group A tests [sit and reach, medicine ball throw (MBT), plank], group B tests [handgrip strength (HGS), standing long jump (SLJ), 20-m sprint (20 ms)] and group C tests [vertical jump (VJ), hanging with bent arm (HBA), Illinois agility test) in order to ensure adequate rest periods between tests and not to affect the results. These group tests were performed 48 h apart, between 09:00-10:00 and 17:00-18:00, after a dynamic warm-up session. Results Significant variations were observed in the sit-and-reach test (t = -4.154, d = -0.75, p < .001), HGS (t = -2.484, d = -0.45, p = .019), SLJ (t = -2.117, d = -0.38, p = .043), VJ (t = -5.004, d = -0.91, p < .001), and plank duration (t = -4.653, d = -0.84, p < .001). Evening performances showed improvement in MBT, HBA, 20 ms, and the Illinois agility test, although these differences were not statistically significant (p > .05). Notably, positive correlations were identified between participants' chronotypes and their performance in HBA (morning/evening; r = .693, p = .026; r = .656, p = .039, respectively) and the plank (evening; r = .717, p = .020), with negative correlations noted in the 20 ms (morning/evening; r = -.703, p = .023; r = -.710, p = .021, respectively). Conclusion The findings suggest that individuals with mild ID exhibit enhanced athletic performance during evening hours. These insights underscore the importance of considering chronotype in tailoring exercise interventions for this population to optimize outcomes.Öğe Comparison of echocardiographic parameters of amputee football players with active football players and sedentary individuals(Bmc, 2023) Kurtoglu, Ahmet; Kurtoglu, Ertugrul; Konar, Nurettin; Car, Bekir; Eken, Ozgur; Prieto-Gonzalez, Pablo; Nobari, HadiBackgroundThe purpose of this study is to compare the echocardiographic (ECHO) parameters of amputee football players (AF) with those of athletes without a disability (football players) (FP), and sedentary individuals (SI).MethodsA total of 37 male participants (nAF = 12, nFP = 12, nSI = 13) were included in the study. All participants underwent a transthoracic echocardiographic examination. Aortic diameter in systole (ADs), aortic diameter in diastole (ADd), isovolumic contraction time (IVCT), isovolumic relaxation time (IVRT), left ventricular ejection fraction (LVEF), early (E) and late (A) wave velocities, myocardial systolic (S), early diastolic (E'), and late diastolic (A') myocardial rates, interventricular septal thickness (IVS), left ventricular end-diastolic diameter (LVDd) and left ventricular end-systole diameter (LVDs), left ventricular posterior wall thickness (LVPWd), left atrial diameter (LAD), and ascending aortic diameter (AAD) were measured.ResultsLVDd, E' were lower in AF than in FP. In contrast, LVDs, LVPWd, and A wave were higher in AF than in FP. When AF and SI groups were compared, ADs, LVPWd, A wave, IVRT, and S wave were higher in AF than in SI. ANOVA test showed a statistically significant difference between groups in LVPWd, A-wave, and E' wave. TTE data indicate that some parameters in AF differ from those observed in healthy individuals. The smaller LVEED diameter and higher PWT were found in AF.ConclusionsAlthough within normal limits, some ECHO parameters in the AF group differed from those without disability. Future studies should further investigate these differences using different and detailed measurement methods.Öğe The effect of chronic leg press exercises on hamstring muscle length and different vertical jump performance(Iermakov S S, 2024) Kurhan, Sebiha; Kurtoglu, Ahmet; Kurhan, Cihad Onur; Eken, Ozgur; Car, BekirBackground and Study Aim As it is known, chronic resistance exercises cause limitations in some joints and this negatively affects the normal range of motion. In the present study, it was aimed to analyse the quadriceps -hamstring balance by analysing different vertical jump performances after six weeks of leg press exercise. Material and Methods Eleven university students aged between 18-30 years were included in this study. The hamstring muscle length, 1 repetition maximum (1-RM) leg press performance were analysed before and after six weeks of leg press exercise. In addition, the vertical jump performances of the participants were analysed with My Jump 2 software programme. In this study, counter movement jumps (CMJ) and squat jump (SJ) performances of the participants were determined. Results According to the findings, 1 repetition maximum (1-RM) leg press performance and hamstring length of the participants improved significantly (t=-7.609, ES: -2.29, p<.001; t=-2.540, -0.76, p=.029, respectively). CMJ and SJ parameters of the participants did not change (p<0.05). It was concluded that the lengthened hamstring length after the leg press exercise programme had a positive relationship with vertical jump height (r=0.656, p=0.028), flight duration (r=0.663, p=0.026), speed (r=0.657, p=0.028), and average speed (r=0.669, p=0.024). These relationships were observed among CMJ parameters following the exercise programme. Likewise, a positive correlation was found between hamstring length, which lengthened after the leg press exercise programme, and vertical jump height (r=0.625, p=0.040), flight duration (r=0.646, p=0.032), speed (r=0.646, p=0.032), and average speed (r=0.637, p=0.035). These correlations were identified among the SJ parameters after the exercise. Conclusions As a result, it was determined that chronic leg press exercises positively affected hamstring muscle length and muscle strength. Different vertical jump performances such as CMJ and SJ did not change. However, the relationship between hamstring length and vertical jump parameters is interesting.Öğe The effect of time of day on Special Judo Fitness Test in active judokas: Evaluation in terms of chronotype(Taylor & Francis Inc, 2024) Eken, Ozgur; Ceylan, Halil Ibrahim; Kurtoglu, Ahmet; Simenko, JozefThe present cross-sectional study aims to examine the effect of time of day on the judo-specific performance in judokas, considering their chronotypes. Twenty-four male judokas participated in the study where the Morningness-Eveningness Questionnaire was administered, and on it, they were divided into morning-type (MT:12-judokas) and evening-type groups (ET:12-judokas). Afterwards, the Special Judo Fitness Test (SJFT) was applied to both groups at three different times (morning: 09:00 h, afternoon: 13:00 h and evening: 17:00 h) with body temperature measured before and after every SJFT performance. As a result, the Group*Test Time interaction significantly affected overall throwing performance during SJFT [F(2,44) = 29.437, p = 0.001, eta 2p: .572]. Furthermore, a significant time effect was found for the SJFT index [F(2,44) = 5.118, p = 0.010, eta 2p: .189] and for the Group*Test Time interaction with the mean value of the index [F(2,44) = 24.424, p < 0.001, eta 2p: .526]. Furthermore, body temperature had a significant time effect [F(2,44) = 301.454, p < 0.001, eta 2p: .932] and the Group*Test Time interaction [F(2,44) = 5.802, p = 0.006, eta 2p: .209]. In conclusion, coaches and exercise experts should consider judo athletes' chronotype when planning special training programs to improve judo-specific anaerobic capacity. Furthermore, to minimize the impact of time of day and chronotype on athletes' performance in competitions, it is recommended that MT athletes develop their judo-specific anaerobic capacity in the evening hours, when their performance is lower, while ET athletes should do so in the morning hours when their performance is lower via randori training.Öğe Effects of an eight-week bosu ball exercise program on core strength endurance and balance performance in intellectually disabled adolescents(Springer, 2024) Kurtoglu, Ahmet; Car, Bekir; Topoglu, Sevin; Isbasaran, Dervis Alper; Eken, Ozgur; Nobari, HadiThe objective of this study is to investigate the impact of an eight-week bosu ball exercise (BBE) program on core strength endurance and balance performance in intellectually disabled (ID) adolescents. Twenty-nine participants (14 males and 15 females) between the ages of 11 and 14, who had been diagnosed with moderate and mild intellectual disabilities (ID) by the Provincial Guidance Research Center they were affiliated with, were included in the study. The participants underwent an eight-week program of BBE. The plank test, endurance of the right (R) and left (L) lateral flexors, endurance of abdominal muscles, and endurance of back extensor muscles were assessed to determine core region endurance before and after BBE. Additionally, balance performance was evaluated using the Y balance test. The right (R) and left (L) leg Y balance test performances of the participants before and after BBE did not change significantly according to the group*time interaction (p>0.05). In the time interaction, L-Anterior (L-An) [F-(1,F- 27)=4.273, eta(2)(p)=.137,p=.048], L-Postmedial (L-PM) [F-(1,F- 27)=15.244, eta(2)(p)=.361,p<.001], L-Postlateral (L-PL) [F-(1,F-27)=10. 703, eta(2)(p)=.284,p=.003], R-An [F-(1,F- 27)=9.833, eta(2)(p)=.267, p=. 004], R-PM [F-(1,F- 27)=9.958, eta(2)(p)=. 269,p=.004], R-PL [F-(1,F- 27)=15.681, eta(2)(p)=.367,p<.001] values increased significantly. When the core strength parameters of the participants were examined; extensor muscle endurance showed a significant change in favour of men in the group-time interaction [F-(1,F- 27)=6.619, eta(2)(p)=.197, p=.016]. In the time interaction, plank [F-(1,F- 27)=16.204, eta(2)(p)=.375, p<.001], R-lateral flexor muscles [F-(1,F- 27)=14.140, eta(2)(p)=.344,p<.001], L-lateral flexor muscles [F-(1,F- 27)=12.379, eta(2)(p)=.314,p=.002], abdominal muscle [F-(1,F- 27)=8.418, eta(2)(p)=.238,p=.007], extensor muscles [F-(1,F- 27)=17.802, eta(2)(p)=.397,p<.001] parameters in males and females. As a result, BBE could be considered a preferred exercise modality to reduce the risk of fall-related injuries caused by balance impairment and inadequate trunk strength, which are prevalent among individuals with intellectual disabilities (ID).Öğe Effects of chronic core training on serum and erythrocyte oxidative stress parameters in amputee football players(Frontiers Media Sa, 2023) Kurtoglu, Ahmet; Konar, Nurettin; Akcinar, Faruk; Car, Bekir; Uremis, Nuray; Turkoz, Yusuf; Eken, OzgurObjective: The positive impact of aerobic exercise on blood oxidative stress parameters is well documented. However, the effect of core exercises on these parameters in amputee football players (AF) remains unclear. Therefore, this study aims to investigate the impact of core exercises on blood oxidative stress parameters in this population.Methods: Experimental method was adopted in the study. Eleven elite AF players participated in the study. The participants were divided randomly into two groups a core exercise group (CEG) and a control group (CG). Blood measurements were taken before and after the 8-week core exercise program. Blood measurements included erythrocyte Total Oxidant Status (eTOS), erythrocyte Total Antioxidant Status (eTAS), erythrocyte oxidative stress index (eOSI), serum nitric oxide (sNO), serum Total Oxidant Status (sTOS), serum Total Antioxidant Status (sTAS), serum oxidative stress index (sOSI), serum total thiol (sTT), serum native thiol (sNT), and serum disulfide (sDS) parameters were studied.Results: According to the results of the study, a significant difference was found between the 0th and eighth week pre-aerobic training load (ATL) sTOS (p = .028) values of CEG values. A significant difference was found in sTOS (p = .028) and sOSI (p = .028) values after the 0th and eighth-week pre-ATL. A significant difference was found in the sTOS (p = .043) and sOSI values (p = .043) of CG at week 0th and eighth-week pre-ATL.Conclusion: Overall, the results suggest that core exercises had a positive effect on blood oxidative stress parameters in AF players by reducing blood total oxidant levels.Öğe Effects of short-term pre-competition weight loss on certain physiological parameters and strength change in elite boxers(Public Library Science, 2024) Yasul, Yavuz; Akcinar, Faruk; Yasul, Muhammet Enes; Kurtoglu, Ahmet; Eken, Ozgur; Badicu, Georgian; Ardigo, Luca PaoloBackground Athletes in certain sports aim to gain an advantage by competing in a lower body mass class instead of competing in their own body mass class. This study aims to reveal certain physiologic and strength changes in elite male boxers who lost body mass rapidly before the competition.Methods 30 thirty boxers who were aged between 19-24 years and having a mean age of 7.4 years participated in the study. To evaluate the effect of short-term dietary intake interventions on body composition and muscle strength before the competition, boxers were divided into three groups: control (C), exercise+diet1 (E+D1) and exercise+diet2 (E+D2) groups. The dietary habits of the participants were controlled and they participated in the training program. The data of the study consisted of variables such as body mass, height, regional muscle mass, body fat percentage, biceps and femur bicondylar circumference measurements before the competitions. Isometric strength measurements of knee extensors and flexors and shoulder internal and external rotators were also recorded.Results Physiologic parameters such as body mass change, BMI level, body fat percentage and leg muscle ratios of E+D2 were significantly decreased compared to C and E+D1 groups. Furthermore, submaximal and maximal strength production in knee extensors and flexors as well as shoulder internal and external rotators were significantly decreased in E+D2 compared to C and E+D1 groups.Conclusion The tendency to lose body mass quickly in a short of time may give the desired results in terms of BMI, body mass and fat percentage, but it may cause strength losses in boxers during the competition period.Öğe Enhancing Pulmonary Function in Children with a 4-week Yoga Exercise Program: A Randomized Controlled Trial(Wolters Kluwer Medknow Publications, 2025) Soyler, Mehmet; Kurtoglu, Ahmet; Aydin, Engin; Senol, Ilkin; Car, Bekir; Eken, Ozgur; Aldhahi, Monira I.Background: Yoga is a widely recognized form of aerobic exercise that has gained significant popularity in recent years, with well-documented positive effects on respiratory functions. However, there is a limited body of research investigating the impact of yoga performed for various durations. Therefore, this study aimed to investigate the acute and chronic effects of a 4-week hatha yoga (HY) exercise program with different durations (60 min and 30 min) on pulmonary function in sedentary young individuals. Methods: A total of 52 sedentary individuals aged 15-16 years were randomly divided into three groups: 60 min HY group (60 min HY, n = 21), 30 min HY group (30 min HY, n = 15), and control group (CG, n = 16). The 60 mHY and 30 mHY groups underwent a yoga exercise protocol twice a week for 4 weeks, while the participants in the CG were instructed on the physical activity guidelines but did not perform yoga exercises. Pulmonary function profile was assessed using a spirometer device. Results: The forced vital capacity of the groups in the 60 mHY group increased after 4 weeks compared to the 30 mHY and CG groups (P = 0.002, 95% confidence interval [CI] = -1.10- -0.07). The forced expiratory volume in one second (P < 0.001, 95% CI = -0.03-0.54) improved in the 60 mHY group. Peak expiratory flow was least improved in the CG (P = 0.004, 95% CI =-1.23 to - 0.32). Forced expiratory flow between 25% and 75% (FEF25/75) of vital capacity changed the most at 60 mHY (P = 0.004, 95% CI=-1.72 to - 0.49). The forced expiratory time varied with time but did not differ across the groups. Conclusions: A 4-week HY program, particularly with 60-min sessions, significantly improved pulmonary function in sedentary young participants. The findings suggest that the longer the duration of HY, the greater the effects on the pulmonary system, and therefore, we suggest that the effects of yoga programs on different populations should be investigated.Öğe Evaluating the impact of rock climbing on mental health and emotional well-being in adolescents(Frontiers Media Sa, 2024) Gurer, Huseyin; Akcinar, Faruk; Arslan, Semiha Comertoglu; Akcinar, Serpil; Gullu, Mehmet; Eken, Ozgur; Kurtoglu, AhmetBackground: Rock climbing (RC) has gained attention as a therapeutic tool in psychiatric settings that merges physical exertion with mental engagement. It has potential to enhance mental health, through improved self-efficacy and social interaction, making it a novel intervention for addressing anxiety, depression, and behavioral issues in adolescents. This study aimed to investigate the effects of RC as a physical activity on anxiety, depression, and emotional and behavioral problems in adolescents. Methods: The current study included 57 athletes aged 14.5 +/- 1.7years and 91 adolescents aged 13.6 +/- 1.2years, matched for age and gender, who were not professionally involved in sport. In addition to the socio-demographic form, a detailed psychiatric assessment was carried out by the child psychiatrist; using the Schedule for Affective Disorders and Schizophrenia for School-Age Children Present and Lifetime Version (K-SADS-PL) to detect psychiatric conditions. The Revised Child Anxiety and Depression Scale-Child Version (RCADS-CV) and the Strengths and Difficulties Questionnaire (SDQ) were also administered to the adolescents in the study. Results: In the comparative analysis of the RCADS-CV outcomes between the athlete and control groups, the athletes demonstrated notably lower scores for both Separation Anxiety Disorder (SAD) and Generalized Anxiety Disorder (GAD), yielding p-values of < 0.001 and 0.031, respectively. Although the mean scores for social phobia, OCD, panic disorder, and MDD were lower in the athlete group, the differences were not statistically significant (p>0.05). In the correlation analysis, a moderately significant correlation was found between the duration of doing sport and the scale scores for SAD (p:0.010), OCD (p:0.014), and panic disorder (p:0.016). There was no significant difference between groups in terms of SDQ scores. Conclusion: These results suggest that RC, through its unique combination of physical exertion and mental focus, may offer protective benefits against certain anxiety disorders among adolescents. Further studies should be conducted to explore the potential use of RC as a preventive program for both healthy adolescents, as well as those with psychiatric disorder.Öğe Evaluation of electrocardiographic parameters in amputee football players(Frontiers Media Sa, 2023) Kurtoglu, Ahmet; Kurtoglu, Ertugrul; Akguemues, Alkame; Car, Bekir; Eken, Oezguer; Sarbu, Ioan; Ciongradi, Carmen IuliaObjectiveThe present study aimed to compare electrocardiographic (ECG) parameters of amputee football players (AF) with football players without disability (FP) and sedentary individuals without disability (SI). MethodsA total of 32 participants (AF = 9, FP = 11, SI = 12) were included in the study. ECG parameters including P-wave amplitude, P-wave duration, PR interval, QRS duration, RR interval, QT interval, corrected-QT interval (QTc), ST segment duration, Tp-e duration, Tp-e/QT and Tp-e/QTc ratios were assessed in all the study participants by using a 12-lead ECG device. OneWay ANOVA Test was used for statistical analysis. ResultsOf all ECG parameters, P-wave amplitude and QTc were significantly higher in the AF group in comparison to FP and SI groups. QRS duration was found to be lower in the AF group when compared to FP and SI groups. Myocardial repolarization parameters including Tp-e duration, Tp-e/QT and Tp-e/QTc ratios were similar between groups, as were other parameters such as P-wave duration, PR interval, RR interval, QRS duration and QT interval. ConclusionIt was found that some ECG parameters of amputee football players differ from those with non-disabled players and non-disabled sedentary individuals. These different parameters were within normal limits.Öğe Exploring the Impact of Physical Inactivity on Digital Gaming Attitudes and Addiction among Secondary School Students(Romanian Assoc Balneology, 2024) Kurhan, Sebiha; Car, Bekir; Kurhan, Cihad Onur; Kurtoglu, Ahmet; Eken, Ozgur; Polat, GulsenThe escalating concern regarding internet and digital game addiction among pre-adolescent children and its potential link to psychological issues prompted this study, aimed at evaluating digital game addiction levels and attitudes towards gaming in secondary school students. Conducted with a sample of 897 students from Ankara, T & uuml;rkiye, the study employed a survey method, utilizing the Attitude Scale towards Digital Game Addiction and Digital Games. Results indicated significant gender differences in addiction levels and attitudes, with boys showing higher scores. Age also played a role, with seventh graders exhibiting the lowest and eighth graders the highest addiction behaviors. Notably, those engaged in martial arts games and using consoles for gaming reported the highest addiction and positive attitude scores. The study underscores the prevalent issue of digital game addiction among youths, suggesting a strong correlation with physical inactivity. It concludes that promoting physical activity is essential not only for physical health but also as a preventative measure against the development of psychological issues stemming from digital game addiction.Öğe Exploring the quadriceps muscle architecture variations in various sports disciplines: a comparative analysis of football, taekwondo, and athletics(Edizioni Minerva Medica, 2024) Ciftci, Rukiye; Kurtoglu, Ahmet; Car, Bekir; Karavas, Erdal; Eken, Ozgur; Soyler, Mehmet; Ardigo, Luca P.BACKGROUND: The purpose of this study was to comprehensively investigate and compare the architecture of the quadriceps muscle in football, taekwondo, and athletics, shedding light on potential differences and providing valuable insights for athletic training and performance enhancement. METHODS: Thirty-five athletes (football[N.]=14. [7 women, 7 men]; taekwondo [N.]=11. [6 women, 5 men]; athletics [N.]=10. [5 women, 5 men]) aged 17-21 years participated in the study. After participant demographic data were collected, 2D real-time B -mode ultrasound (USG) and right (R) and left (L) leg quadriceps muscle group rectus femoris (RF), vastus intermedius (VI), vastus lateralis, pennation angle (PA), RF cross-sectional area (CSA), and subcutaneous fat thickness were determined. RESULTS: In the study, in female athletes, R-RF+VI (P=0.04, ES:4.34), R -VI (P=0.01, ES: 6.1), R-RF: (P=0.009, ES: 7.9), R-CSA (P=0.04, ES: 5.2), L-RF (P=0.002, ES: 10.4) and L-CSA (P=0.007, ES: 7.7) significant differences were found in favor of the Football group. In male athletes, R-CSA (P=0.004, ES: 9.05), L-RF (P=0.05, ES: 3.5) and L-SFT (P=0.00, ES: 13.6), there was a significant difference in favor of the Football group. L -PA (P=0.009, ES: 6.2). L -PA (P=0.009, ES: 6.2) was significantly higher in the male Taekwondo group. CONCLUSIONS: Our research findings show that there is a significant relationship between the type of exercise performed and the structural differences observed in the quadriceps muscle. Consequently, it is highly recommended to consider the outcomes of our study for enhancing the efficacy of training programs in the domains of football, taekwondo, and athletics.Öğe Gonarthrosis related changes in quadriceps muscle architecture and physical function outcomes in women(Nature Portfolio, 2025) Ciftci, Rukiye; Kurtoglu, Ahmet; Eken, Ozgur; Aldhahi, Monira I.This study aimed to assess the effects of gonarthrosis on quadriceps muscle architecture and fatigue, physical function, and postural balance in women compared with healthy controls. Eighty-one females diagnosed with gonarthrosis (n = 40) and healthy control group (n = 41) aged between 47 and 77 years participated in the study. After demographic data were collected, right and left rectus femoris (RF), vastus intermedius (VI), vastus lateralis (VL) thicknesses and RF pennation angle (PA) were determined using a 2D real-time ultrasound device (USG). RF and VI depths and RF cross-sectional area (CSA) were obtained using ultrasound with the probe positioned in a transverse orientation to the muscle. In addition, the participants underwent the timed up and go test (TUG), 30-sec sit-and-up test (SU30s), and completed the Fatigue Severity Scale (FSS). The relationship between functional tests and right and left quadriceps muscle architecture parameters was also analyzed. In our study, the right CSA (p < .001, t=- 8.609, ES = 1.92), left VL (p = .020, t= - 2.365, ES = 0.052), and left CSA (p < .001, t=- 10.164, ES = 2.26) were significantly higher in the healthy group. Conversely, TUG (p < .001, t = 4.882, ES = 1.08) and FSS (p < .001, t = 10.362, ES = 2.29) were significantly higher in the gonarthrosis group, while SU30s values were higher in the control group (p < .001, t = - 12.262, ES = 2.73). Additionally, a negative correlation was observed between SU30s and CSA, whereas TUG and FSS showed a positive correlation with CSA (p < .001). According to the results of our study, some morphological losses were observed in the quadriceps muscle architecture of participants with gonarthrosis. Decreases in CSA affect functional performance. Determination of quadriceps muscle architecture in patients with gonarthrosis can be used to predict functional loss.Öğe Immediate effect of exercise and music on attention among school-age youth: A comprehensive experimental study(Lippincott Williams & Wilkins, 2025) Kurtoglu, Ahmet; Koca, Mehmet Emek; Turkmen, Musa; Car, Bekir; Eken, Ozgur; Setiewan, Edi; Elkholi, Safaa M.Background/objectives: Low attention level, especially in school-age children in preadolescence and adolescence, affects educational activities. The effects of different types of music and exercise on attention level have been an important subject of research for many years. The aim of this study was to examine the effect of aerobic and yoga exercise intervention program applied synchronously with different types of music on the attention level of primary 2 students studying. Materials and methods: In this study, 19 male (age = 12.63 +/- 0.83 years, height = 145.78 +/- 4.58 cm, weight = 47.73 +/- 7.94 kg, body mass index = 22.43 +/- 3.51 kg/m(2)), 27 female students (age = 12.40 +/- 1.15 years, height = 141.03 +/- 3.34 cm, weight = 42.14 +/- 4.13 kg, body mass index = 21.15 +/- 1.45 kg/m(2)) were included. Participants performed 3 different exercise programs (no exercise [NE], aerobic exercise [AE], and yoga exercise [YE]) without music (NM), listening to traditional music (TM), classical music, and current popular music (PM), after which participants' attention was analyzed using the Burdon Attention Test. Results: In the NE group, participants' attentional levels were lower in the NM condition compared to TM and PM (P = .019, Delta = -7.86, Std. Err = 2.23; P = .001, Delta = -9.74, Std. Err = 2.22, respectively). During AE and YE, different music genres had no effect (P > .05). As a result of the post hoc analysis, the attention test results obtained from the NM and TM genres in the NE protocol were significantly lower than the attention test results obtained from all music genres during AE and YE (P < .05). There was no significant difference between the values obtained from NE-PM and the values obtained from AE and YE (P > .05). At the same time, attention test results did not change between AE and YE during any music genre. Conclusions: In conclusion, exercise and music are important elements to increase the attention level of school-age individuals. In addition, PM may be an important factor in increasing attention levels in these individuals.Öğe The impact of strategic napping on peak expiratory flow and respiratory function in young elite athletes(Bmc, 2024) Kurtoglu, Ahmet; Eken, Ozgur; Aydin, Engin; Car, Bekir; Nobari, HadiRespiratory health is a critical determinant of athletic performance, and the utilization of restorative strategies, such as strategic napping, may offer a competitive edge to athletes. This study investigates the effects of nap duration on the respiratory function of young elite athletes who have achieved top rankings national competitions. Participants engage in three test sessions with varying nap durations: no nap (N0), a 25-minute nap (N25), and a 45-minute nap (N45), with a minimum 72-hour interval between sessions. Respiratory parameters including Forced Vital Capacity (FVC), Forced Expiratory Volume in one second (FEV1), FEV1/FVC ratio, Peak Expiratory Flow rate (PEF), Forced Expiratory Flow at 25-75% of FVC (FEF25-75%), and Forced Expiratory Time (FET) are assessed. Results reveal a significant enhancement in PEF values following a 45-minute nap (N45) compared to the no-nap control (N0) [F1 - 11=7.356, p =.004, eta p2 = 0.401, (95% CI for difference: -1.56 to - 0.056)], indicating a potential positive influence of napping on maximum expiratory flow rate and, consequently, athletes' respiratory performance. While no significant changes are observed in other respiratory parameters across different nap durations, these findings underscore the potential benefits of strategic napping in optimizing respiratory health in young elite athletes.Öğe The insufficiency of recreational exercises in improving cardiovascular fitness: an investigation of ventricular systolic and diastolic parameters and left atrial mechanical functions(Bmc, 2023) Akgumus, Alkame; Kurtoglu, Ahmet; Aydin, Engin; Balun, Ahmet; Car, Bekir; Eken, Ozgur; Aldhahi, Monira I.AimThis study aimed to compare the left ventricular (LV) systolic and diastolic parameters and left atrial (LA) mechanical functions of individuals engaging in recreational sports and resistance exercises on a weekly basis.MethodsA total of 43 male amateur athletes were included in this study, of which 24 performed resistance exercises (REs) (29.70 +/- 8.74 year, weight: 81.70 +/- 12.64 kg, height: 176.05 +/- 7.73 cm, BMI: 27.64 +/- 4.97 kg/m2), and 19 participated in recreational football training and were included in the recreational sports group (31.73 +/- 6.82 year, weight: 86.00 +/- 18.52 kg, height: 178.62 +/- 4.95 cm, BMI: 25.55 +/- 3.42 kg/m2). The exercises were standardized according to the weekly exercise frequency and volume. After recording the participants' demographic information, the LV systolic and diastolic parameters and LA mechanical functions were measured using echocardiography (ECHO) and Tissue Doppler Imaging.ResultsSignificant differences were observed in various cardiac parameters between the recreational sports group (REG) and resistance exercise Group (RSG). Specifically, the left ventricular (LV) diastolic diameter, LV end diastolic volume index (LVEDVi), and stroke volume index were notably higher in the REG compared to the RSG (t = 2.804, p = .010, effect size (ES) = 2.10; t = 3.174, p = .003, ES = 0.98; t = 3.36, p = .002, ES = 1.02, respectively). Notably, the RSG exhibited higher values for LV mass index (LVMi) and isovolumic relaxation time (IVRT) than the REG (t = 2.843, p = .007, ES = 0.87; t = 2.517, p = .016, ES = 0.76) in terms of LV systolic and diastolic parameters. Regarding left atrial (LA) mechanics, the REG demonstrated increased LA total emptying volume index, LA maximum volume index, LA volume before systole measured at the onset of the p-wave index, and conduit volume index compared to RSG (t = 2.419, p = .020, ES = 0.75; t = 2.669, p = .011, ES = 0.81; t = 2.111, p = .041, ES = 0.64; t = 2.757, p = .009, ES = 0.84, respectively).ConclusionOur study revealed significant variations in LV and LA functions between REG and RSG. Our data suggest that REs led to substantial cardiac remodeling, altering myocardial structure and function. In contrast, the effect of recreational exercise on cardiac adaptation was less pronounced than that of resistance exercise. Consequently, we propose that individuals engaging in recreational exercise should consider modalities that impose higher cardiovascular demand for more effective cardiac conditioning.Öğe Investigating the Impact of Body Composition Analysis on Quality of Life and Anxiety-Depression in Adult Males with Chronic Obstructive Pulmonary Disease(Mdpi, 2025) Kurtoglu, Ahmet; Eken, Ozgur; Ciftci, Rukiye; Cicek, Ipek Balikci; Durmaz, Dilber; Deniz, Mine Argali; Aldhahi, Monira I.Background/Objectives: Chronic obstructive pulmonary disease (COPD) is a progressive respiratory disorder characterized by systemic manifestations, including altered body composition, reduced quality of life, and psychological distress. Despite its significance, the relationship between body composition parameters and symptoms of fatigue, anxiety, and depression in patients with COPD remains underexplored. This study aimed to examine the association between detailed body composition metrics and quality of life, fatigue, and anxiety and depression symptoms in male patients with COPD compared to healthy controls. Methods: This cross-sectional study included 49 men with COPD and 51 age-matched healthy controls aged 50-80 years. Body composition was assessed using bioelectrical impedance analysis (BIA). Pulmonary function, dyspnea, activities of daily living, and psychological status were evaluated using spirometry, the Medical Research Council Dyspnea Scale, the London Chest Activity of Daily Living Scale (LCADL), and the Hospital Anxiety and Depression Scale (HADS), respectively. Results: Compared to the controls, patients with COPD exhibited significantly lower forced expiratory volume in one second (FEV1: 1.1 vs. 2.16 L; p < 0.001), lower fat mass (15.0 vs. 24.3 kg; p < 0.001), and higher muscle mass (53.8 vs. 42.0 kg; p < 0.001). They also reported significantly greater fatigue (Borg scale: 4 vs. 0; p < 0.001), higher anxiety (8 vs. 5; p = 0.006), and depression scores (11 vs. 5; p < 0.001), along with more pronounced limitations in their daily activities. Conclusions: COPD is associated with profound impairments in body composition, physical function, and mental health. Detailed body composition analysis using BIA provides valuable clinical insights and may aid in tailoring individualized interventions to improve quality of life and psychological outcomes in COPD management.Öğe Investigation of Factors Affecting Shuttle Walking Performance at Increased Speed for Patients with Chronic Obstructive Pulmonary Disease(Mdpi, 2023) Ciftci, Rukiye; Kurtoglu, Ahmet; Eken, Ozgur; Durmaz, Dilber; Eler, Serdar; Eler, Nebahat; Aldhahi, Monira I.The aim of this study was to examine the factors affecting the shuttle walking test (SWT) in patients with chronic obstructive pulmonary disease (COPD). A total of 29 patients with COPD (the COPD group) and a healthy group (HG) of 34 women aged between 55 and 74 years were included in the study. After the pulmonary function profiles of the participants were assessed, and the SWT was performed. Walking distances, walking speeds, and SWT levels (SWT-L) were determined with the SWT. Before and after the SWT, the heart rate (HR), oxygen saturation level (SPO2), and Borg scale (perceived exertion (BSe) and dyspnea (BSd)) results were analyzed with a paired sample t-test. The dyspnea levels during activity of daily living were determined with the Medical Research Council (MRC) dyspnea scale, and the relationship between MRC dyspnea (MRCD) and walking distance, speed, and SWT-L was tested using multiple linear regression and Pearson correlation analysis. The walking distance, speed, and SWT-L were lower in the COPD group (p < 0.001) than in the HG. The HR values before and after the SWT changed significantly in the COPD group and the HG (p< 0.001), and the effect size was higher in the COPD group. Although the BSe and BSd results before and after the SWT in the COPD group increased significantly (p < 0.001), they did not change in the HG. There was a highly negative correlation between MRCD and walking distance, speed, and SWT-L in the COPD group (p = 0.002, p = 0.000, and p = 0.001, respectively), but no correlation was found in the HG. The results showed that the HR, perceived exertion, and dyspnea levels of women with COPD whose respiratory functions were lower than the HG were significantly affected on the SWT.Öğe Investigation of left atrial mechanical function and left ventricular systolic and diastolic parameters in athletes performing resistance exercise and combined exercise(Bmc, 2024) Kurtoglu, Ahmet; Akguemues, Alkame; Balun, Ahmet; Aydin, Engin; Kurtoglu, Ertugrul; Car, Bekir; Konar, NurettinSome individuals who go to fitness centers for various purposes perform resistance exercise (RE) alone, while others engage in combined exercise (CE) by including cardio exercises along with RE. Studying the effects of these two different training methods on left ventricular (LV) systolic and diastolic parameters and left atrial mechanical function is an important step toward understanding the effects of different types of exercise on cardiac function. This knowledge has significant implications for public health, as it can inform the development of targeted and effective exercise programs that prioritize cardiovascular health and reduce the risk of adverse outcomes. Therefore, the primary aim of this study is to comprehensively investigate the LV systolic and diastolic parameters of athletes who engage in RE and CE using ECHO, to contribute to the growing body of literature on the cardiovascular effects of different types of exercise. Forty-two amateur athletes aged between 17 and 52 were included in our study. The participants consisted of the RE (n = 26) group who did only resistance exercise during the weekly exercise period, and the CE group (n = 16) who also did cardio exercise with resistance exercises. After determining sports age (year), weekly exercise frequency (day), and training volume (min) in addition to demographic information of RE and CE groups, left ventricular systolic and diastolic parameters and left atrial functions were determined by ECHO. Findings from our study revealed that parameters including the left ventricular end-diastolic diameter (LVEDD) (p = .008), left ventricular end-diastolic volume (LVEDV) (p = .020), stroke volume index (SV-I) (p = .048), conduit volume (CV-I) (p = .001), and aortic strain (AS) (p = .017) were notably higher in the RE group compared to the CE group. Also left atrial active emptying vol & uuml;me (LAAEV) of CE was higher than the RE group (p = .031). In conclusion, the cardiac parameters of the RE group showed more athlete's heart characteristics than the CE group. These results may help to optimize the cardiovascular benefits of exercise routines while minimizing the potential risks associated with improper training.
