Öğe Does nitric oxide intake affect post-exercise recovery in athletes? A study on cocoa, caffeine and nitric oxide supplement(Mattioli 1885, 2020) Mor, Ahmet; Yilmaz, Ali Kerim; Acar, Kursat; Birinci, Mursit Ceyhun; Ipekoglu, GokhanBackground: The beneficial effect of popular supplements and use of nitric oxide (NO) precursor nutrients in athletes which aim at increase of sports performance. Objective: The aim of this study is to investigate the effect of nitric oxide precursor nutrients and some nutrients with the ability to increase NO levels in the body on increased NO production in metabolism and on the recovery after acute exercise. Materials and Methods: 8 volunteers, male athletes, in shape and trained participated into this study. Athletes were subject to research protocol every other day, a total of three times. Heart rate and lactate levels were determined at resting and recovery. Results: Statistically significant difference was detected between control and cocoa/caffeine (CC) groups in the 1 minute lactate levels. Lactate levels significantly decreased in the CC group compared to the control group in the 1 minute lactate levels (p<0.05). Statistical significance difference was found between the nitric oxide supplement (NOX) and CC groups in the 1 and 10 minutes heart rate levels. Heart rate levels significantly decreased in the CC group compared to the NOX group (p<0.05). Heart rate levels were significantly decreased in the CC group compared to the control and NOX groups in the 15 minute measurement (p<0.05). Conclusions: Nitric oxide consumed as a supplement in line with nutrition and recovery strategies in athletes improved the recovery by accelerating lactate excretion from the body after the exercise. All of these metabolic responses in the present study suggest that NO will have a positive effect on exercise performance and recovery.Öğe Effect of supplementation with type 1 and type 3 collagen peptide and type 2 hydrolyzed collagen on osteoarthritis-related pain, quality of life, and physical function: A double-blind, randomized, placebo-controlled study(Turkish Joint Diseases Foundation, 2025) Genc, Ahmet Serhat; Yilmaz, Ali Kerim; Anil, Berna; Salkilic, Esra Korkmaz; Akdemir, Enes; Sancakli, Aykut; Mor, AhmetObjectives: The aim of this study was to assess the effect of Naturagen (R) 4 Joint product, containing type 1, 2, and 3 collagen, on pain associated with osteoarthritis (OA) and to evaluate its effects on quality of life and physical functioning. Patients and methods: This double-blind, randomized, placebo-controlled clinical study included a total of 31 patients (8 males, 23 females; mean age: 53.5 +/- 9.1 years; range, 35 to 65 years) with Grade 2-3 OA according to the Kellgren-Lawrence (KL) classification system between June 2023 and November 2023. The patients were divided into two groups: a collagen group (n=16) and a placebo group (n=15). The Visual Analog Scale (VAS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Knee Injury and Osteoarthritis Outcome Score (KOOS-PS), Oxford Knee Score (OKS), Tampa Scale for Kinesiophobia (TSK), Short Form Health Survey (SF-12), Foot Function Index (FFI), Timed Up and Go (TUG), 6-Min Walking Test (6MWT), Five Repetition Sit to Stand Test (5STS), Stair Climbing Test (SCT), and Berg Balance Scale (BBS) were used. All tests were performed before and after eight weeks of collagen supplementation. Results: Eight weeks of collagen supplementation yielded notable enhancements across all osteoarthritis-related pain and quality of life scales evaluated, including VAS, WOMAC, KOOS-PS, OKS, TSK, SF-12, and FFI scores (p<0.05). In functional evaluations, there were significant positive effects of collagen use in BBS and 6MWT results (p<0.05). In TUG, 5STS, and SCT tests, no significant difference was found between the groups (p>0.05). Conclusion: Our study results suggest that the eight-week collagen-based supplement exerts a favorable effect on pain and quality of life levels, as well as some functional test results.Öğe Examination of Anthropometric Characteristics of Police Academy Students(Soc Chilena Anatomia, 2022) Kabadayi, Menderes; Mayda, Muhammet Hakan; Yilmaz, Ali Kerim; Karaduman, Emre; Erail, Serhat; Bostanci, Ozgur; Karakas, FatihAnthropometric data, which is highly correlated with health and high level of physical capacity, is very important for police officer. The aim of this study was to examine the anthropometric data of police college students and compare in terms of gender. Fifty-two police college students (32 females and 20 males) participated in the present study. Index calculations were made by applying anthropometric test measurements to all participants. The data included anthropometric (length measurements, width measurements, circumference measurement) and index [Body Mass Index (BMI), Cormic Index (C-Index), Body Adiposity Index (BAI), Ponderal Index (PI), Conicity Index (Con-Index) Waist-to-Height Ratio (WHtR)] parameters. The Independent Sample T-Test was used to analyze the difference in groups. A statistically significant difference was found in all parameters except leg length in length measurements (p<0.05). The mean of all width measurements except shoulder width of females was higher than that of male participants. Differences were obtained in all variables except hand and hip-width (p<0.05). In circumference measurements, there was a difference between the groups in the measurement values of the relaxed arm, maximum arm, wrist, shoulder, chest, and hip circumferences (p<0.05). The BAI, PI, WHtR, and Con-Index values were significantly different between groups (p<0.05). In conclusion, the length, width, circumference, and kinanthropometric indexes of male and female police candidates differ. Although male have higher mean values in length and circumference measurements, female have a higher mean for width measurements. Females have higher mean values in general in terms of index values and they are inincreased risk group in terms of WHtR index. It can be recommended for all participants, especially females, to participate in regular physical activity after they start working.Öğe Functional dimorphism and relationship between different lower extremity strength tests in young elite judokas(Univ Leon, Fac Ciencias Actividad Fisica & Deporte, 2021) Acar, Kursat; Yilmaz, Ali KerimThe present study investigated the limb symmetry index (LSI) and the relationship between different functional strength tests in young elite judokas. Seventeen males (age=16.88 +/- 1.40 years, height=179.00 +/- 7.00 cm, weight= 78.76 +/- 15.22 kg and BMI 24.40 +/- 3.36 kg/m(2)) participated in the study voluntarily. Participants were tested with single leg (SL), and triple leg (THD) hop for distance, crossover hop for distance (CHD), 6 m Timed Hop Test (6mTHT), and single-leg vertical jump (SLVJ) tests, and countermovement jump (CMJ). All SL hop tests (SLHT) were applied to both right (R-s) and left sides (L-s), while CMJ was applied as without (CMJ(WAS)) and with arm swing (CMJAS). Paired sample t-test and Pearson correlation tests were used in statistical analyses. In all SLHTs, no statistical significance was found between R-s and L-s. However, significance was found between CMJ(WAS) and CMJ(AS). There was also no significance in LSIs between all SLHTs. Correlations were found between SL, THD, CHD, VJ tests, while negative and significant correlations were found between SL, THD, CHD, VJ tests, and 6 m THT. No significance was found between SLHTs and CMJ(WAS) and CMJ(AS). As a result, it was found that Rs and Ls of young judokas produced similar strength in SLHTs, while they caused differences in CMJ(WAS) and CMJ(AS) values; when evaluated in terms of LSI, judokas showed similar rates in all SLHTs, and these rates were within reliable ranges; SLHTs had correlations with each other, but they did not show any correlation with CMJ.Öğe Futbolcularda Glutamin ve Kreatin Suplementasyonunun Vücut Hidrasyon Düzeyi ve Bazi Performans Parametrelerine Kombine Etkisi(Akan BAYRAKDAR, 2024) Mor, Ahmet; Karakas, Fatih; Yilmaz, Ali Kerim; Mor, Hakki; Acar, Kürsat; Arslanoglu, ErkalBu çalismanin amaci futbolcularda glutamin&kreatin suplementasyonunun vücut kompozisyonu ve vücut hidrasyon düzeyi ile birlikte, bazi performans parametrelerine kombine etkisini arastirmaktir.

The present study aimed to examine the relationship between shooting performance, respiratory muscle strength, and pulmonary function and to determine differences in respiratory capacities according to the shooting performance categories in police cadets. One hundred sixty-seven police cadets were recruited to assess respiratory muscle strength, pulmonary function, and shooting performance in a well-controlled environment. Measurements included maximal inspiratory pressure (MIP), maximal expiratory pressure (MEP), forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC), slow vital capacity (SVC), maximal voluntary ventilation (MVV), and pistol shooting scores. The shooting score had a moderate positive correlation with MIP (rho = 0.33) and MEP (rho = 0.45). FVC (rho = 0.25), FEV1 (rho = 0.26), SVC (rho = 0.26) (p < 0.001) and MVV (rho = 0.21) (p < 0.05) were slightly correlated with shooting score. There were differences between shooting performance categories in MIP, MEP, FVC, FEV1, SVC, and MVV (p < 0.001, p < 0.05). The results imply that both strong respiratory muscles and optimal pulmonary function may be one of the necessary prerequisites for superior shooting performance in police.Öğe Prosocial and antisocial behaviors in Turkish female and male football players(Imr Press, 2022) Acar, Kursat; Mor, Hakki; KarakaS, Fatih; Yilmaz, Ali Kerim; Arslanoglu, Cansel; Mor, AhmetBackground and objective: Women have increasingly taken more part in a rather male-dominated sport in recent years: football, so our study's main focus is exploring the acts and behaviors of the female athletes during a football match. The study analyzes the sex-related differences in prosocial and antisocial behaviors between male and female athletes. Materials and methods: A total of 837 players, recruited from various leagues in Turkey, participated in the study. Participants were active female (n = 432) and male (n = 405) football players. The informed consent form and Prosocial and Antisocial Behavior in Sport Scale (PABSS) were utilized as data collection tools. Results: Female football players displayed less prosocial and more antisocial behaviors compared to male football players. Among all the league statuses, both female and male players exhibited the highest prosocial and the lowest antisocial behaviors in the top league status. Additionally, there were statistically significant differences concerning the age variable (p < 0.05). Conclusions: Our study findings indicate that male football players engaged in more prosocial behaviors toward both their teammates and opponents than female football players; moreover, male players engaged in less antisocial behaviors in general. Players reported higher prosocial and lower antisocial behavior scores as league status increased. Lastly, higher prosocial behavior scores were obtained with increasing age.Öğe The Effect of Isolation on Social Physique Anxiety and Fat Phobia in Athletes During the Covid-19 Pandemic(Lahore Medical Research Center Llp, 2021) Acar, Kursat; Yilmaz, Ali KerimBackground: COVID-19 and social isolation have caused quite important changes in the lives of athletes. The uncertainties introduced by this period could lead to various anxieties and phobias in athletes as well as certain mental concerns Aim: This study examined whether social physique anxiety and fat phobia in athletes during the COVID-19 pandemic and isolation period. Methods: The study included 1031 sub-elite athletes (446 females, 585 males) in individual and team sports aged between 18-27. The social physique anxiety scale (SPAS) and fat phobia scale (FPS) were used as data collection tools Results: Significant difference were found in SPAS levels between team and individual sports, the lowest SPAS levels were in the male individual sports athletes (p<0.05). There were differences in both male and female athletes according to regular training status (p<0.05). In athletes' status of being diagnosed COVID-19, significant difference was found in negative physique evaluation concerns (NPEC) subscale of SPAS between female and male groups without a positive diagnosis (p<0.05). Correlations were found between SPAS and FPS levels in all athletes (p<0.05). Conclusion: SPAS levels were the lowest particularly in male athletes involved in individual sports. SPAS levels of athletes who did and did not regularly train during the isolation were found to be the lowest in male athletes who regularly trained. It was established that the positive diagnosis of COVID-19 did not affect SPAS levels much in athletes; however, female athletes with a positive diagnosis showed high SPAS levels. None of the independent variables in this study was found to create any difference in FPS scores, but the correlation analysis revealed significantly increased FPS levels with increasing SPAS levels. In general, SPAS and FP levels of all athletes were moderate.Öğe The effect of supplementation with type I and type III collagen peptide and type II hydrolyzed collagen on pain, quality of life and physical function in patients with meniscopathy: a randomized, double-blind, placebo-controlled study(Bmc, 2025) Genc, Ahmet Serhat; Yilmaz, Ali Kerim; Anil, Berna; Salkilic, Esra Korkmaz; Akdemir, Enes; Guzel, Berna; Mor, AhmetBackground Menisci, one of the most important anatomical structures of the knee joint, plays a role in load transfer, stability, shock absorption, prevention of articular cartilage degeneration, and proprioception. Type I collagen, the main component of the meniscus, and type II collagen fibers play an important role in the stability of the knee joint. This study aimed to evaluate the effects of Naturagen (R) 4 Joint product containing type I, II, and III collagen on pain, quality of life, and physical functions in patients with meniscopathy. Methods This randomized, double-blind, placebo-controlled clinical study included 32 patients (collagen = 17 and placebo = 15) with meniscopathy. Patients completed the Visual Analog Scale (VAS), Western Ontario and McMaster Universities Osteoarthrtis Index (WOMAC), Knee Injury and Osteoarthritis Outcome Score Physical Function Short Form (KOOS-PS), Oxford Knee Score (OKS), Tampa Scale for Kinesiophobia (TSK), Short Form Health Survey (SF-12), Lower Extremity Functional Scale (LEFS), Foot Function Index (FFI), proprioceptive sensation, Timed Up and Go (TUG), 6-Minute Walking Test (6MWT), The Five Repetition Sit to Stand Test (5STS), Stair Climbing Test (SCT), Berg Balance Scale (BBS) and back and leg strength tests and scales were applied. All tests were repeated before and after eight weeks of collagen supplementation. Results The study showed that eight weeks of supplementation with various collagen types had statistically significant effects on pain, quality of life, kinesiophobia, and foot function scale scores in patients with meniscopathy (p < 0.05). Similarly, eight weeks of supplementation showed a statistically significant difference in leg strength (p = 0.057), but no significant difference was found in back strength, proprioception, balance, and various functional test results (p > 0.05). Conclusions The results of the study showed that the eight-week collagen-based supplement had a positive effect on pain and quality of life levels and some functional test results in patients with meniscopathy. Longer-term studies and diversification of subject groups will help to understand better the effects of the product on meniscal tears and symptoms.Öğe The effects of BCAA and creatine supplementation on anaerobic capacity and ball kicking speed in male football players(Mre Press, 2022) Mor, Ahmet; Acar, Kursat; Yilmaz, Ali Kerim; Arslanoglu, ErkalBackground and objective: The use of nutritional supplements has increased in recent years. This study analyzes the effects of Branched-Chain Amino Acids (BCAA) and creatine (CR) supplementation on anaerobic capacity and ball kicking speed in football players. Material and methods: 24 volunteer-active male amateur football players between 18-26 were recruited for this study. Football players were randomly divided into three groups as BCAA (n = 8), CR (n = 8), and placebo (PLA) (n = 8). Experimental groups were given 5 g BCAA and 2 g creatine before and after exercise, whereas the placebo group ingested bran, performance tests and measurements were performed, and results were assessed. Results: BCAA group average power (pre: 530.70 +/- 53.73 W vs. post: 567.65 +/- 66.68 W; p = 0.028), CR group minimum power (pre: 413.75 +/- 51.13 W vs. post: 462.82 +/- 71.93 W; p = 0.043) increased, while there were decreases in peak power (pre: 659.34 +/- 121.03 W vs. post: 613.20 +/- 124.24 W; p = 0.043) and fatigue index (pre: 6.55 +/- 2.12 W/s vs. post: 4.34 +/- 2.37 W/s; p = 0.043) parameters of PLA group (p < 0.05). There were statistically significant differences in the BCAA group in rest, pre-and post-supplementation; CR group in pre-and post-supplementation; PLA group in rest, pre-and post-supplementation (p < 0.05). Conclusions: BCAA and creatine consumption do not affect recovery rates in football players regarding obtained data. But, regarding other findings of this study, BCAA and creatine supplementation improves anaerobic capacity, provides strength endurance against fatigue, and prevents the decrement of ball-kicking speed in exhaustion.
