3D biomechanical analysis of targeted and non-targeted drag flick shooting technique in field hockey
(Drustvo Pedagoga Tjelesne & Zdravstvene Kulture, 2018) Eskiyecek, Canan Gülbin; Bingül, Bergun Meriç; Bulgan, Ciğdem; Aydın, Mensure
The aim of this study was to compare targeted and non-targeted drag flick field hockey shooting techniques in the penalty corner area, using a three-dimensional kinematic analysis. Eleven male field hockey players playing in the super league (mean age: 19,82 +/- 1,40 years) participated voluntarily. Seven high-speed cameras (Oqus 7+) with 120Hz refresh rates were used. Field calibration was completed via the wand method. The data were evaluated in two phases: start and finish. Players undertook three drag flick shots to the box using targeted and non-targeted techniques. The angular kinematics and stroke force applied to the stick were analyzed using the Qualisys Track Manager Program V2.12, and ball velocity statistics were gathered with the SPSS 18.0 program. To compare between the targeted and non-targeted shots of the drag flick shooting techniques, t-test was applied. At the drag flick of the players, significant differences were noticed at the angular speed of the right shoulder and the left knee, and the angular acceleration of the right hip in the starting phase, and also at the right hip angular acceleration at the finish phase. When the ball speed data considered, a significant decrease was observed between the targeted and non-targeted drag flick shots. Significant correlation was found out between some variables, at the angular kinematics and both force applied on the stick and the ball speed values (p <= 0.05). In conclusion, to make an accurate target shot the players maximize their targeted shooting rates, particularly by decreasing the speed of their lower extremities.
Determining the Knowledge Levels and Opinions of Athletes Who Is Age Under-16 in Different Branches About Doping and Ergogenic Aids
(Mattioli 1885, 2020) Ceylan, Abdil; Calik, Febmi; Geri, Serdar; Sen, Murat; Ece, Cuma; Sumer, Mebmet
Study Objectives: The study aimed to evaluate the knowledge levels and opinions of athletes under 16 years of age about doping and ergogenic aids in different branches. The fact that there are no studies in the literature on the knowledge and opinions of athletes under the age of 16 on doping and ergogenic aids has encouraged us to the study. Methods: The sample of the study consists of 392 athletes under 16 years of age in different sports branches. In the study, a questionnaire consisting of 5 likert and 26 questions about doping substances and ergogenic aids was applied to the athletes by Eroz (2007). Results: As a result of the analysis of the obtained findings with the Chi-square test, it was determined that as the age of the athletes increased, the belief that the athlete used doping increased with the fear of losing. It has been determined that as the family income increases, the tendency to try every way to be successful does not decrease significantly, and athletes with low family income are more willing to try every way to be successful. As the education of the athlete's parents increased, the belief that the use of doping harmed the Fair-Play spirit in sports and that doping leads to unfair competition has been increased. Conclusion: The study revealed that there is a need to reinforce the doping knowledge of athletes. It has been concluded that certain socio-economic conditions are determinants in the use of doping by athletes and that they shape their tendency towards doping. Therefore, it is thought that the trainers, managers, athlete families and athletes about the negative effects of doping use on athlete health is of great importance.
Latmos: A semiotic view on the subject's role in the sustainability of natural and cultural values
(Semiotica, 2023) Kalelioǧlu, Murat
Along with the developments in social, scientific, and technological fields, today’s conditions are constantly changing and becoming much more complex. Humans must keep pace with the rapidly changing world, meet requirements, and solve various problems encountered with minimal damage. One of the most crucial obligations is to preserve the delicate balance between nature and culture to make it sustainable for humanity. This study is carried out pursuant to semiotics with an interdisciplinary perspective dealing with the relation of culture with nature and the role of humans, as a subject, in this relation regarding both natural and cultural heritages of Latmos. The study examines the subject’s acts and possible influences on nature, culture, and society in the region. It is seen that there is an uphill battle between two different subjects; the reason for this is a conflict of interest encountered on individual and social planes. On the one hand, one of the subjects is aware of the positive effects of preserving natural and cultural values on society and its future. On the other hand, another subject is unaware of all these or is aware of them but ignores natural and cultural values and destroys them for the sake of self-interest.
Seasonal Analysis (Six-Months) of Blood Parameters of Kyrgyz Elite Athletics Athletes Before 2016 Rio Olympics Games
(Carbone Editore, 2021) Kisadere, Ihsan; Dzhanuzakov, Kanat; Patlar, Suleyman; Kilic, Mehmet; Gunay, Mehmet; Abdyrakhmanova, Dciparkul; Demirhan, Bilal
Objective: In this study, exercise-induced changes in blood parameters of Kyrgyz elite athletes were evaluated during 6 months. Methods: Eight male (n = 8) and three female (n = 3) athletes were included. Blood samples were taken at 3 months intervals before and after the exercise (shuttle run). Erythrocyte (RBC), total leukocyte (WBC), platelet (PLT), neutrophil (NOTR), lymphocyte (LNF) count, hemoglobin (HGB) and hematocrit (HCT) values, mean erythrocyte volume (MCV), mean erythrocyte hemoglobin concentration (MCHC) and also venous blood pH, PO2, PCO2, SAT O2, HCO3, BE, Na, K, Cl, serum glucose (Glu), total protein (TP), total cholesterol (TC), HDL cholesterol (HDL-C), triglyceride (Trig), blood urea nitrogen (BUN), creatinine (Creat), lactate dehydrogenase (LDH) and creatinine phosphokinase (CPK) levels were determined. Results: The WBC, LNF, and NOTR values of the male athletes were found high (p < 0.05) after the exercise periods. In male athletes, HDL-C and BUN levels increased (p < 0.05), while Glu levels (p < 0.05) decreased due to exercise in each measurement. An increased pO2, O2SAT, K, and Anion Gap levels, however, decreased pH, pCO2, HCO3, and BE values were determined after the exercise. Conclusion: Our data showed that exercise caused an acute increase in immune system cell counts (WBC, LNF and NOTR), also HDL-C and O2SAT values in male elite athletics athletes, but the six-month period did not cause any significant change in all of the blood parameters.
