Öğe Effect of dynamic and static strength training on hormonal activity in elite boxers(Gdansk Univ Physical Education & Sport, 2020) Aggon, Eser; Agirbas, Ozturk; Alp, Hamit Hakan; Ucan, Izzet; Gursoy, Recep; Hackney, Anthony C.Background: The aim of this study was to determine hormonal responses to acute and chronic exposure to static and dynamic strength training programs using resistance bands in boxers. Material and methods: 19 male national boxers participated in the study. Boxers were instructed to perform strength exercises with resistance bands for 3 days a week for 8 weeks involving either dynamic (n=10) or static (n=9) resistance exercises. Blood samples were taken before exercise, immediately after the initial exercise session, and 8 weeks later following the last exercise session. Cortisol, growth hormone, adrenocorticotropic hormone adrenaline and noradrenaline levels were measured. Statistical analyses involved non-parametric analysis with an alpha level of .05. Results: Dynamic strength exercises were effective stimuli to growth hormone, adrenaline and noradrenaline, while static strength exercises provoked cortisol, growth hormone, adrenaline and noradrenaline responses both initially after exercise and after 8 weeks of chronic training. Neither dynamic nor static strength exercises were effective in prompting adrenocorticotropic changes after an exercise session or after 8 weeks of training. Conclusions: We showed that dynamic and static strength exercise protocols using resistance bands both could provoke acute and chronic hormonal responses in boxers similar to more traditional modes of such exercise.Öğe The effect of extreme sports on oxidative stress(Archives Budo Science Martial Arts & Extreme Sports, 2017) Aggon, Eser; Agirbas, Ozturk; Ucan, Izzet; Hackney, Anthony C.Background & Study Aim: Despite the high risk of extreme sports, participation rates have increased in the last years. Rafting and paragliding are two of the most popular extreme sports. The aim of this study was the effect of rafting and paragliding exercises in males on oxidative stress situation and antioxidant status. Material & Methods: Seventeen male rafters and ten male paragliders voluntarily participated in the study. The inclusion criteria were: non-smoker, no known history of cardiovascular disease, body mass index (BMI) < 30 kg/m2, and no intake of medications or antioxidant supplements. Blood samples were taken at rafting and paragliding practices' a day before and after the sporting activities. The data were statistically analysed with Wilcoxon and Mann-Whitney U tests. Results: Rafting activity increased the values of the total antioxidant situation (TAS), paragliding exercises decreased the level of TAS while paragliding increased the level of total oxidative stress (TOS). Differences existed between the group only before activities in TAS values. Conclusions: The specific property of the rafting workout is to stimulate of participants to cope with oxidative stress by activating the antioxidant status. In turn paragliding exercises increase oxidative stress due to the danger element in the sport and perhaps requiring the participants stay at a high altitude, in some situations, during its practice.Öğe THE EFFECT OF PROGRESIVE RELAXATION TRAINING ON FREE RADICALS, ANTIOXIDANT SYSTEM AND OXYDATIVE DNA DAMAGE(Parlar Scientific Publications (P S P), 2018) Aggon, Eser; Ozturk, Nurinnisa; Alp, Hamit Hakan; Siktar, Elif; Agirbas, Ozturk; Bakan, EbubekirThis study aimed in sedentary subjected to progressive relaxation training (PRT) for determination of the effect of this exercise on MDA, OHdG, and NO levels and SOD and GPx activities. Experimental design was used in this research. Seven healthy, sedentary volunteers were included in the study. All subjects were male and within 15 to 18 years of age. Jacabson's Progressive Muscle Relaxation Training was applied to the volunteers for 6 six weeks. Before and after the chronic and acute exercise, blood samples were taken from the subjects, and K-Related Samples Friedman test was used for the analysis of repeated measurements and for the comparison of pre- and post-exercise data and chronic and acute mode data. In addition, 2-Related Samples Wilcoxon test was used in the evaluation of the groups as pairs. Our findings showed increases in MDA PRT, and no statistically significant increase in NO levels after PRT in sedentary volunteers. When the effect of relaxation exercise on the antioxidant system is considered, both SOD and GPx activities increased. The effect of PRT on 8-OHdG has been found to exhibit significant increase after PRT. It can easily be said that PRT may be helpful in patients with chronic disease, especially for obtaining a healing and a high quality sleep. In addition, in order for the athletes to feel well and to use their muscles actively, PRT may be helpful. We can conclude that, with respect to human health and physiology, no controversy may be seen in progressive muscle relaxation training.Öğe The Effects of Strenght Exercises on Body Composition and Irisin(Int Journal Applied Exercise Physiology, 2020) Ozan, Murat; Karakurt, Sercan; Aggon, Eser; Agirbas, Ozturk; Ucan, Ezzet; Alp, Hamit HakanThis is the first study to determine the effects of strenght exercises on irisin and correlation of bady composition and irisin. The purpose of this study was to determine the effects on body composition and irisin of static strength exercises with Tera-Bant (R) in elite boxers. 9 volunteered elite male boxers participate in the study who are nonsmokers and did not use any nutritional supplements. Boxers were instructed to perform strength exercises with Thera-Band for 3 days a week for 8 weeks. Blood samples were taken before exercises (resting), after the first exercise (acute) and after 8 weeks following the last exercise (chronic), and measurement of body fats were made at the same time. Irisin levels of blood were examined. Statistical analyses were carried out using the SPSS 22 for Windows. The data were found to not be distributed normally. Thus, Friedman, Wilcoxon, Mann-Whitney U and Speraman's correlations tests were used. The results were evaluated using an alpha level of .05. Body Fat Percentage (BFP) and Fat Mass (FM) levels of athletes increased, Lean Mass (LM) decreased relatively both after a single session and after 8 weeks. While irisin concentration increased after a single session, (correlation in pre exercise and after a single exercise. Static strength exercise is effective on body fat both acutely and chronically, and effective on irisin only acute. Farther, the body fat and irisin are related to the negative.Öğe The Relationship Between Strength, Speed, Flexibility, Agility, and Anaerobic Power in Elite Athletes(Int Journal Applied Exercise Physiology, 2019) Tatlisu, Bulent; Karakurt, Sercan; Agirbas, Ozturk; Ucan, IzzetThe aim of this study was to determine whether there is a relationship between strength, speed, flexibility, agility, and anaerobic power in elite athletes. In various sport branches 29 active male athletes participated in this study with an average age of 21.14 +/- 1.98 years who without any health problems. Back and leg strength were measured by dynamometer (Takei), speed was measured by 20 meters test, agility was measured by T test, flexibility was measured by sit and reach test, vertical jump sit-reach test by Jumpmeter (Takei) anaerobic power was calculated by the Lewis formula. The data were analyzed in SPSS 22.0 for Windows package program. Bivariate - Pearson Correlation test was used to determine the relationship between strength, speed, flexibility, agility, and anaerobic power. The results were interpreted as .05 significance level. We were found positive and significant relationships between the back and leg force, between anaerobic power and vertical jumping, between anaerobic power and back force, between anaerobic power and leg strength, and between flexibility and vertical jumping. And also, there was a negative and significant relationship between flexibility and agility, between speed and vertical jump, and between agility and vertical jump. In this study, it was concluded that strength, vertical jump and anaerobic power was related both each other and the other. For this reason, we recommend that the trainings cover all motoric characteristics.
