Evaluation of doping knowledge level and tendency, volleyball player who plays i̇n the first and second league in Turkey

The aim of this research is to evaluate the doping knowledge level and tendency among volleyball players playing in the first and second leagues in Turkey, The sample of the study is composed of the volleyball players of Efeler League consisting of 12 teams and Sultanlar League consisting of 12 teams with their 144 players in total, and 173 players chosen among the 56 teams in the First League man-women A and B Categories Volleyball Federation of Turkey in 2017-2018 season. For this purpose, the survey as a tool used for data collection was prepared based on expert opinion and it was conducted to a population of 30 volleyball players. The survey was reassessed depending on the survey results by eliminating the defects in survey questions. Furthermore, a validity-reliability study was also conducted for the survey. A reliability study was conducted by using Cronbach Alpha internal consistency method and the value obtained is 0.743 and the number of items was found as 17. Throughout the study, a literature survey was conducted, the historical evolution of doping was examined and verified by using numerical data. ut of the selected 173 volleyball players, 53.7% of them are male (N=93), 46.2% of them are female, (N=80), 85 of them have graduated from a university, 81 of them are among 1st League and 92 of them are among 2nd League players. When the players were asked about their knowledge level about diuretics and peptide hormones, a significant difference was found between male and female volleyball players (p<0.05); by the same token, when the players were asked about stimulants, anabolic androgenic steroids, narcotic analgesics and in terms of general doping knowledge level, there is no significant difference between male and female volleyball players (p>0.05). When the distribution of the Doping Knowledge Levels according to the league is evaluated, in terms of level of knowledge about stimulants, it was seen that there was a meaningful difference in favor of volleyball players playing in the 1st League (p<0.05); in terms of anabolic androgenic steroids, beta-blockers, and general doping knowledge, there seems to be a significant difference in favor of volleyball players in the 2nd League. It is seen that there is a significant difference between libero's and setter's, spiker's and middle players in terms of level of knowledge about stimulants according to the position they are playing (p<0.05). When the average values of doping information level are examined, it seems that libero has the lowest level of knowledge about stimulants, Furthermore, in terms of the level of knowledge about anabolic androgenic steroids, between spiker and libero, it is understood that there is a significant difference in favor of libero, on the other side, in terms of the level of knowledge about beta-blockers between setter and libero, it is understood that there is a significant difference in favor of the libero (p<0.05). According to the results of the research; in terms of the level of doping knowledge of the players according to their position, it seems that there is a meaningful difference between libero and setter as well as between spiker and middle players (p<0.05). When the average values of doping information level are examined, liberos have the lowest level of knowledge. As a result, the fact that the doping information of the athletes who are in a more active position in the match is meaningful is equivalent to the information of others who may use doping for success.
