Glavni namen raziskave je bil izvedeti, koliko rekreativnih športnikov uporablja dovoljene substance, koliko od njih je nagnjenih k uporabi nedovoljenih substanc ter kakšno je njihovo znanje o delovanju in stranskih učinkih dovoljenih in nedovoljenih substanc. V raziskavo smo vključili 164 rekreativnih športnikov, ki se ukvarjajo s skupinskimi vadbami, 34 je bilo moških in 130 žensk. Njihova starost je bila od 18 do 75let. Za raziskavo smo uporabili anonimen vprašalnik, ki nam je podal njihove splošne podatke, podatke o uporabi alkohola in kajenja, podatke o prehrani in dopingu ter o znanju glede prehrane in dopinga. Rezultati so pokazali, da več kot 50% rekreativnih športnikov uporablja prehranske dodatke. Največ se poslužujejo proteinov, vitaminov in mineralov. Raziskali smo kakšne so razlike med spoloma v uporabi prehranskih dodatkov in ugotovili, da moški pogosteje uporabljajo prehranske dodatke. Do največjih razlik je prišlo pri uporabi izotonikov, ogljikohidratov ter proteinov. Ugotovili smo tudi da ni razlik v uživanju dodatkov med mlajšimi in starejšimi rekreativci, razen pri uporabi proteinov, ki jih več zaužijejo mlajši. Lastno mnenje anketirancev o poznavanju prehranskih dodatkov je bilo večinoma srednje ali dobro, o poznavanju dopinga pa slabo ali srednje. Pri preverjanju dejanskega znanja o dopingu in prehranskih dodatkih pa se je izkazalo, da je njihovo znanje slabo, ne glede na starost. Znanje o dopingu in prehranskih dodatkih so najpogosteje pridobili samostojno, na internetu ali drugi literaturi. Po njihovem razmišljanju bi uporabnike dopinga morali kaznovati s prvič blažjo kaznijo in drugič doživljenjsko prepovedjo, prepovedjo za nekaj sezon ali takoj doživljenjsko prepovedjo. Velika večina jih dopinga ne bi nikoli poskusila. The main purpose of the research was to find out how many recreational athletes use the permitted substances, how many of them are inclined to use prohibited substances, and what their knowledge of the functioning and side effects of permitted and prohibited substances was. We included 164 recreational athletes involved in group workouts, 34 men and 130 women. Their age ranged from 18 to 75 years. For the survey we used an anonymous questionnaire, which provided us with their general data, data on the use of alcohol and smoking, information on diet and doping, and knowledge of nutrition and doping. The results showed that more than 50% of recreational athletes use dietary supplements. Proteins, vitamins and minerals are the most used. We examined the gender differences in the use of dietary supplements and found out that men are more likely to use dietary supplements. The greatest differences occurred in the use of isotonic, carbohydrate and protein. We also found out that there are no differences in the use of supplements among younger and older recreational athletes, except for the use of proteins that are more ingested by the younger ones. The opinion of the respondents on the knowledge of dietary supplements was mostly moderate or good, while the knowledge of doping was poor or moderate. When checking the actual knowledge about doping and dietary supplements, it turned out that their knowledge is poor, regardless of age. Knowledge of doping and dietary supplements was most often acquired by themselves, on the Internet or in other literature. In their opinion, users of doping should be penalized with a first time milder sentence and then second time lifetime ban, a ban for several seasons or a lifetime ban straightaway. The vast majority would never try doping.

Glavni namen raziskave je izvedeti, kako dobro moški, ki se ukvarjajo s fitnesom poznajo prehranske dodatke, koliko jih uporablja dodatke in če pozitivno vplivajo na njihovo telesno sestavo. V raziskavo smo vključili 50 moških, starih od 18 do 60 let, ki se s fitnesom redno ukvarjajo vsaj leto dni (najmanj 2x tedensko). Raziskava je potekala od meseca marca do julija 2016, v šestih fitnesih po Ljubljani. Raziskava je zajemala meritve telesne sestave, ki smo jih opravili s tehtnico Tanita (Tanita, Innerscan body composition monitor, model BC-545), ki temelji na šest točkovnem merjenju z magnetno impendanco. Na podlagi anketnega vprašalnika pa smo dobili podatke o starosti, spolu, otrocih, izobrazbi, načinu vadbe, količini vadbe, ter znanju in uporabi prehranskih dodatkov. Rezultati so pokazali, da 84% moških, ki se ukvarja s fitnesom uživa prehranske dodatke. Ugotovili smo tudi, da imajo moški, ki uporabljajo dodatke k prehrani višjo telesno višino, nižji odstotek maščobe in manj mišične mase. Z raziskavo je bilo ugotovljeno tudi to, da ima večina moških (54%), ki se ukvarja s fitnesom slabo znanje o prehranskih dodatkih. S primerjavo dveh starostnih skupin (do 40 let in nad 40 let) pa smo ugotovili, da imajo starejši v povprečju višjo telesno maščobo in višjo vitalno starost. The main purpose of this research is to find out, how well do men, who work out in a gym, know the dietary supplements, how much do they use them and whether or not the dietary supplements affect their body structure in a positive way or not. 50 men from the age of 18 to 60, who work out on a regular basis (at least two times a week), were included in this research, which took place from March to July 2016 in six different gyms across Ljubljana. The research includes the measurements of the body structure that were completed with Tanita scale (Tanita, Innerscan body composition monitor, model BC-545), which is based on six point measurement with magnetic impedance. It is also based on survey questionnaire that includes questions about age, gender, children, education, the way and quantity of a workout, knowledge and usage of dietary supplements. We found out that 84% of men, who work out on a regular basis, use dietary supplements. We also found out that men, who use dietary supplements, have a higher height, lower percentage of fat and muscle mass. The research also showed that 54% of men, who workout in a gym, have poor knowledge about dietary supplements. The comparison between two age groups (under 40 years and above 40 years) showed that older people have higher percentage of body fat and higher vital age.
