Öğe The effects of different recovery methods on anaerobic performance in combat sports athletes(Univ Palackeho & Olomouci, Fak Telesne Kultury, 2021) Yarar, Hakan; Gök, Ümit; Dağtekin, Ahmet; Saçan, Yunus; Eroğlu, HüseyinBackground: Athletes, who engage in combat sports, perform often several matches in a day during competitions. For this reason, recovery is a very important factor between matches. There are many different recovery methods applied by athletes and it is very important to know which one is more suitable for anaerobic performance. Objective: The aim of this study was to investigate the effects of different recovery methods on anaerobic performance in combat sports athletes. Methods: Thirteen experienced international level elite combat sports athletes (age 20.5 +/- 1.6 years, body height 175.3 +/- 4.5 cm, body mass 73.8 +/- 7.9 kg, body fat 11.4 +/- 3.9%, training experience 7.5 +/- 3.4 years) have participated voluntarily in this study. Athletes were involved in passive recovery (PR), cold water immersion (CWI) and active recovery (AR) methods after countermovement jump and Wingate anaerobic test. Also, body temperature and rating of perceived exertion were evaluated. In this study, a randomized crossover design was used and applications lasted three days. All measurements were performed at three different times (baseline, 1st and 2nd session) in a day. Two-way analysis of variance with repeated measures was used for statistical analysis. Results: For the countermovement jump there was a significant increase after CWI and AR. A significant decrease was found in the Fatigue index after CWI recovery. Body temperature was increased after CWI, AR, and PR. Rating of perceived exertion has increased in AR. Moreover, there were no significant differences were found in peak power and mean power. Conclusions: The results indicate that during intermittent recovery, CWI positively impacted countermovement jump and fatigue index. Also, AR has positively affected countermovement jump performance, while negatively affected the rating of perceived exertion. Thus our findings suggest that 10 min of CWI and AR can be adopted in competitions when successive matches take placeÖğe Elit seviyedeki sporcuların beslenme bilgi ve alışkanlıklarının değerlendirilmesi(2011) Yarar, Hakan; Gökdemir, Kadir; Eroğlu, Hüseyin; Özdemir, GünayBu çalışma ülkemizi uluslararası alanda temsil eden çeşitli branşlardaki elit sporcuların beslenme konusundaki bilgi ve alışkanlıklarını tespit etmek amacıyla yapılmıştır. Araştırmada denek grubunu, Basketbol, Voleybol, Futbol, Hentbol, Atletizm, Eskrim, Halter, Tenis, Tekvando, Güreş, Judo, Yüzme, Boks, Jimnastik, Badminton, Pentatlon, Kayak ve Okçuluk branşlarıyla uğraşan 18 farklı olimpik branştan rastgele seçilen elit düzey 334 sporcu oluşturmuştur. Veriler, konu uzmanı tarafından hazırlanan anket aracılığıyla toplanmış, istatiksel hesaplamalarda SPSS (version 15.0) programı kullanılmıştır. Elde edilen verilerin frekans ve yüzde değerleri hesaplanmıştır. Sonuç olarak, elit sporcuların sporcu beslenmesi konusundaki bilgilerinin istenilen düzeyde olmadığı, kısmen yanlış beslenme alışkanlıklarına sahip oldukları, büyük çoğunluğunun akademik düzeyde eğitim görmüş ve milli sporcu olmalarına rağmen beslenmelerine yeteri kadar önem vermedikleri kanısına varılmıştır. Beslenme bilgilerinin arttırılması ve doğru beslenme alışkanlıkları kazandırılması için bilimsel destek almaları gerektiği düşünülmektedir.Öğe The investigation of weight loss profiles on weight classes sports athletes(Int Journal Applied Exercise Physiology, 2019) Yarar, Hakan; Türkyılmaz, Recep; Eroğlu, HüseyinPurpose: The purpose of this study was to determine that weight loss profiles of weight category sports athletes. Materials and Methods: 502 active (371 male, 131 female) weight category sports athletes who have lost weight before the competition were participated as a volunteer in this study. The participants consist of Wrestling, Boxing, Weight lifting, Taekwondo, Karate, Judo and Kick box athletes. For the data collection the questionnaire of "Athlete Weight Loss Methodology and Effects Scale" was used Yarar et al.[1]. For statistical analysis descriptive statistics, arithmetic mean (x), standard deviations (ss) and percentage frequency (%) of subjects were calculated on SPSS version 20.0 (statistical package for the social sciences). Results: According to statistical analysis first weight reduction age was 14.72 +/- 2.45 year, average weight loss frequency in a season (time) was 2.62 +/- 1.49, and maximum weight loss ratio in a time was 5.33 +/- 2.72 kg. At the same time 69.52% of the athletes, lose weight in the last 2 weeks before the competition. Furthermore the reason of weight loss 33.6% was body weight is between two categories, 23.1% had good competitors in their category and 23% in order to be faster and more durable. Conclusions: We conclude that the athletes started to lose weight in early ages and many athletes lost weight short time before the competition
