Öğe The Comparison of Judo-Specific Tests(STOWARZYSZENIE IDOKAN POLSKA-IDOKAN POLAND ASSOC, 2018) Ceylan, Bayram; Balci, Sukru SerdarBackground. There are some judo-specific performance tests developed in recent years. It has been reported that these tests present the same physiological results as aerobic and anaerobic power measurements carried out in laboratories. Measurements carried out by using judo-specific exercises are important to control the development of the training. Problem and aim. The aim of this study was to determine whether 3 different judo-specific tests could discriminate judo athletes from different levels and present the same physiological results as simulated judo match. Methods. Eight male judo athletes who have competed in international competitions in the recent year and 7 male judo athletes who have competed in national competitions in the recent year voluntarily participated in this study. During the selection process, some criteria such as at least 4-year judo background, attending trainings regularly and no injuries in the recent year which adversely affected athletes' training program were taken into consideration. Athletes carried out 4 different practices (tests): Special Judo Fitness Test (SJFT), Uchikomi Fitness Test (UFT), Santos Test (ST) and Simulated Judo Match (SJM). Tests were carried out randomly at the same time of the day with at least 2, at most 3 days intervals. Rest values of hearth rate (I IR) and lactate (LA) were measured before tests and at 1st, 5th, 10th, 15th, 30th minutes of the recovery period. Paired comparisons of the variables were tested with independent sample t-test, changes in HR and LA values in both groups were tested with the three-factor mixed-design analysis of variance with repeated measurement. Results. Elite and non-elite athletes were found to have the same physical characteristics except body fat percentage. Time of measurement (F=187.57) and tests (F=21.05) significantly affected the level of lactate (p<0.05), the interaction effect between test and time factors was also found significant (F=8.80; p<0.05). Contrarily, changes of the lactate concentration during the tests were similar in elite and non-elite judo athletes (F=0.82; p<0.05). Conclusion. Despite similar changes in HR and LA only SJFT and ST discriminated elite and non-elite judo athletes in terms of number of throws and test-specific evaluations while UFT did not discriminate the levels of the athletes.Öğe Hydration Status and Fluid Intake of Adolescent Athletes From Different Sports During Training(Selçuk Üniversitesi, 2021 Ağustos) Ceylan, BayramDespite many studies presenting that a high number of adult athletes start exercise in sub-optimal hydration state, limited data concerning hydration levels in athletic youth exists. This study aimed to identify the hydration status of adolescent athletes of different sports during a typical training. Sixty-nine adolescent men athletes from different sports (swimming, judo, basketball, football) voluntarily participated in the study (age: 13.7±1.7 years, experience: 4.8±2.0 years). Measurements were carried out before and immediately after training. Data collection took place at the same time of the day. All athletes trained for about 90 minutes and they consumed fluids ad libitum during their training. Pre-training urine measurement revealed that 58.2% of the athletes started training in dehydrated state (Urine Specific Gravity [USG]?1.020). Besides, 63.3% of the athletes completed the training in also dehydrated state with USG values ? 1.020 and urine colour between 4-6. Mean body weight loss during the training was -0.26±0.40 kg. This study concluded that the prevalence of dehydration in adolescent athletes is high according to USG and urine colour values. Great number of the athletes arrived at training in dehydrated state and dehydrated even more during training despite access to fluids. Some educational programs and measures for optimal hydration in adolescent athletes should be taken into consideration.Öğe Judoya özgü performans testlerinin karşılaştırılması(Selçuk Üniversitesi Sağlık Bilimleri Enstitüsü, 2016) Ceylan, Bayram; Balcı, Şükrü SerdarJudo branşına özgü son yıllarda ortaya konan birkaç performans testi bulunmaktadır. Bu testlerin laboratuarda yapılan aerobik ve anaerobik güç ölçümleriyle benzer fizyolojik cevaplar oluşturduğu rapor edilmiştir. Judocular için branşa özgü egzersizlerle performans ölçümünün yapılması antrenman gelişiminin kontrol edilmesi açısından önemlidir. Bu araştırmada judoya özgü 3 farklı performans testinin judocuların seviyelerini ne düzeyde ayırt edebildiği incelenmiş ve yapılandırılmış judo maçına verilen fizyolojik cevaplarla testler sonrasındaki fizyolojik cevaplar karşılaştırılmıştır. Araştırmaya son bir yıl içerisinde uluslararası yarışmalara katılmış üst düzey 8 erkek judocu ve son bir yıl içerisinde ulusal yarışmalara katılmış 7 erkek judocu gönüllü olarak katıldı. Sporcuların düzenli olarak judo antrenmanı yapıyor olması, en az 4 yıllık judo geçmişinin olmasına ve son bir yıl içerisinde antrenman programlarını etkileyecek uzun süreli ciddi sakatlıklar geçirmemiş olmasına dikkat edildi. Sporcular Özel Judo Kondisyon Testi (SJFT), Uchikomi Kondisyon Testi (UFT), Santos Testi (ST) ve yapılandırılmış 5 dakikalık judo maçı (YJM) olmak üzere 4 farklı uygulamaya katıldı. Uygulamalar her bir sporcu için herhangi bir sıra takip etmeksizin rastgele en az 2 en fazla 3 gün ara ile ve günün aynı saatinde yapıldı. Her test öncesi dinlenme kan laktat seviyeleri ve test öncesi kalp atım hızları ile uygulamalardan 1 dk, 5 dk, 10 dk, 15 dk ve 30 dk sonrasında toparlanma laktat seviyeleri ve kalp atım hızları ölçüldü. Değişkenlerle ilgili ikili karşılaştırmalar bağımsız gruplarda t-testiyle, uygulamlar öncesi ve sonrasındaki beş farklı zamanda kalp atım hızı ve laktat seviyelerindeki değişimlerin gruplarda farklılık gösterip göstermediği tekrarlı ölçümlerde üç faktörlü karışık desenli varyans analiziyle test edildi. Araştırmaya katılan üst ve orta düzey judocuların vücut yağ yüzdesi dışında benzer fiziksel özelliklere sahip olduğu tespit edildi. Ölçüm zamanları (F=187.57) ve test uygulamaları (F=21.05) laktat seviyesini önemli düzeyde etkilemektedir (p<0.05), ayrıca test ve zaman faktörlerinin ortak etkisinin önemli olduğu belirlenmiştir (F=8.80; p<0.05), buna karşın testler süresince laktat seviyelerinin zaman içindeki değişimleri gruplarda benzerdir (F=0.82; p>0.05). Kalp atım hızı ve kan laktat seviyelerindeki benzer değişime karşın sadece SJFT ve ST 'nde üst ve orta düzey judocularda atış saysı ve testlerin kendi içerisindeki değerlendirmeler açısından performans ayırımı yapabildiği, UFT'nde ise sporcuların seviyesini ayırt etmediği saptanmıştır.Öğe Monitoring Hydration Status of Elite Judo Athletes During a Competition Day(Selçuk Üniversitesi, 2020 Nisan) Ceylan, Bayram; Akgül, Mustafa Şakir; Gürses, Veli Volkan; Baydil, Bilgehan; Aydos, LatifDehydration is defined as deficit in total body water and has been suggested to have adverse effects on athletic performance as well as health. Despite ongoing efforts to inform the athletes, especially weight-classified athletes present higher level of dehydration. As judo is a weight-classified sport and athletes are exposed to rapid weight loss methods, hydration status of judo athletes should be monitored for athletes’ health and implications for future precautions. Thus, the aim of this study was to monitor hydration status of elite judo athletes during a competition day. Eighteen (13 males, 5 females) elite judo athletes voluntarily participated in this study. Following body composition measurements, USG and urine color measurements were carried out before and after the competition in order to determine their hydration status. Athletes’ prematch USG value was 1,021 while it was found 1,019 after competitions. As for urine color, it was 5,17 before competitions and 4,87 after competition. According to these results elite judo athletes presented higher level of dehydration during a competition day despite ad libitum fluid intake. Judo athletes and coaches should be informed about adverse effects of dehydration and individual water intake prescriptions for these athletes can be advised. Further research is also advised to confirm that dehydration negatively affects judo specific performance.
