Doping u sportu predstavlja kršenje jednog ili više anti-doping pravila, uključujući korištenje zabranjenih supstanci koje povećavaju učinkovitost i/ili korištenje zabranjenih prikrivajućih tehnika. Osim što ozbiljno ugrožava zdravstveni status pojedinca, doping narušava imidž sporta i njegove osnovne vrijednosti pa se borba protiv dopinga nameće kao jedna od najvažnijih tema u sportu danas. Cilj istraživanja bio je utvrditi faktore povezane s doping ponašanjem kod sportaša uključenih u sportove izvedbe, točnije kod veslača, jedriličara i plivača. Ispitanike u istraživanju sačinjavalo je ukupno 240 sportaša (159 muškaraca, 81 žena) iz veslanja (58 muškaraca, 9 žena), jedrenja (42 muškarca, 38 žena) i plivanja (59 muškaraca, 35 žena). Varijable su prikupljene kroz 2 prethodno validirana upitnika: Questionnaire of Substance Use (QSU), (ii) Knowledge of Doping and Performance-Enhancing Drugs (KD), a generalno ih je moguće podijeliti na (1) sociodemografske faktore, (2) sportske faktore, (3) faktore znanja o prehrani i dopingu i (4) doping faktore. Kao kriterij je uzeta varijabla potencijalnog doping ponašanja koja je tretirana kao multinomialna varijabla s 3 kategorije: pozitivan, neutralan i negativan stav naspram dopinga. Kod obrade podataka izračunati su deskriptivni statistički podaci ovisno o karakteru varijable (aritmetička sredina i standardna devijacija, odnosno frekvencije i postoci), analiza razlika između sportova i spolova je izračunata t-testom za parametrijske varijable i Chi2, Mann-Whitney i Kruskal-Wallis testom za neparametrijske. U završnoj fazi obrade podataka korištena je multinomialna regresija analiza za izračunavanje povezanosti prediktora i doping ponašanja kao kriterija. Najmanja tendencija dopingu od analiziranih sportova pronađena je u jedrenju gdje 78.75% jedriličara ne bi konzumiralo doping, dok je kod plivača i veslača taj udio 75.53% odnosno 60.32%. Kod sva tri sporta nisu pronađene značajne razlike po pitanju doping ponašanja između različitih dobnih kategorija. Kod uzorka veslača jedini značajan prediktor doping ponašanja pokazala se varijabla u kojoj se ispitivao primarni izvor informacija o dopingu i prehrani. Ukratko, oni veslači kojima su primarni izvor znanja o dopingu vanjski izvori, pokazuju značajno veću tendenciju korištenja dopinga. Kod jedriličara se kao prediktor dopinga pokazalo nekoliko varijabli: „znanje o dopingu“, „povjerenje u službene osobe“, „primarni izvor znanja o dopingu, „kazne za doping prekršitelje“ i „doping u jedrenju“. Jedini faktor koji utječe na doping ponašanje u istraženom uzorku plivača je njihovo mišljenje o prisutnosti dopinga u plivanju. Jednaka tendencija dopinga kod juniora i seniora, koja se pokazala u sva tri analizirana sporta, jasno daje signal za specifično usmjerenom anti-doping kampanjom za adolescente s ciljem stvaranja ispravnih stavova i ponašanja po pitanju sportskih i zdravstvenih navika mladih sportaša. Rezultati istraživanja ukazali su i na potrebu za edukacijom o doping problematici, kako trenera i liječnika koji bi trebali imati povjerenja od sportaša i biti primarni izvor znanja, tako i kod samih sportaša, pogotovo jedriličara kod kojih se znanje pokazalo kao protektivni faktor od doping ponašanja. Nalaz koji se ponavljao u svim sportovima je utjecaj percepcije kontaminiranosti sporta dopingom na pozitivno doping ponašanje. Uzimajući u obzir načela teorije samokategorizacije po kojoj pojedinci prihvaćaju norme i obrasce ponašanja članova grupe s kojom se identificiraju, nameće se potreba za pokretanjem anti-doping trenda u sportovima koji će služiti kao svojevrsni okidač mijenjanja percepcije o prisutnosti dopinga u sportu, a time posljedično smanjiti tendenciju korištenja dopinga.Doping in sports refers to the violation of one or more anti-doping rules, including the consumption of banned performance-enhancing substances and/or the application of prohibited masking techniques. Besides it is serious health-threatening behavior, doping damages sport image and fundamental values so the global fight against doping is one of the most important issues in sports these days. Research aim was to identify factors associated with potential doping behavior for athletes included in performance sports - swimming, Olympic sailing and rowing. Participants in this study in the study consisted of a total of 240 athletes (159 men, 81 women) from rowing (58 men, 9 women), sailing (42 men, 38 women) and swimming (59 men, 35 women). Variables were collected through 3 previously validated questionnaires: Questionnaire of Substance Use (QSU), (ii) Knowledge of Doping and Performance-Enhancing Drugs (KD), and Questionnaire on Factors of Hesitation (QFH), and can generally be divided into ( 1) sociodemographic factors, (2) sports factors, (3) factors of knowledge about nutrition and doping and (4) doping factors. The criterion was a variable of potential doping behavior, which was treated as a multinomial variable with 3 categories: positive, neutral and negative attitude towards doping. Descriptive statistics were calculated depending on the character of the variable (arithmetic mean and standard deviation or frequencies and percentages), analysis of differences between sports and gender were calculated by t-test for parametric variables and Chi2, Mann-Whitney and Kruskal-Wallis test for nonparametric. In the final phase of data analyzing, multinomial regression analysis was used to calculate the association of predictors and doping behavior as criteria. The smallest tendency for doping from the analyzed sports was found in sailing, where 78.75% of sailors would not consume doping, while swimmers and rowers had a share of 75.53% and 60.32%, respectively. In all three sports, no significant differences were found in terms of doping behavior between different age categories. In the sample of rowers, the only significant predictor of doping behavior was the variable in which the primary source of information on doping and nutrition was examined. In short, those rowers whose primary source of knowledge about doping are external unofficial sources, showed a significantly higher tendency to use doping. In sailors, several variables have been shown to be predictors: "knowledge of doping", "trust in officials", "primary source of knowledge about doping", "penalties for doping offenders" and "sailing doping". The only factor influencing doping behavior in the swimmers sample studied, was their opinion of the presence of doping in swimming.The equal tendency of doping in juniors and seniors, which was shown in all three analyzed sports, clearly sends a signal for a specifically targeted anti-doping campaign for adolescents with the aim of creating correct attitudes and behaviors regarding sports and health habits of young athletes. The results of the research also indicated the need for education on doping, both for coaches and doctors who should have confidence from athletes and be the primary source of knowledge, and for athletes themselves, especially sailors whose knowledge has proven to be a protective factor against doping behavior. A recurring finding in all sports is the impact of the perception of sport contamination by doping on positive doping behavior. Taking into account the principles of the theory of self-categorization according to which individuals accept the norms and patterns of behavior of members of the group with which they identify, there is a need to launch an anti-doping trend in sports that will serve as a trigger to change perceptions of doping in sport and consequently lead to lower doping tendency in sport
