Vpliv poznavanja in uporabe prehranskih dodatkov na telesno sestavo žensk, ki se ukvarjajo s fitnesom

Namen raziskave je bil ugotoviti, kako poznavanje in uporaba prehranskih dodatkov vpliva na telesno sestavo žensk, ki se ukvarjajo s fitnesom, koliko žensk, ki se ukvarjajo s fitnes vadbo prehranske dodatke uporablja in kakšno je njihovo znanje o le-teh. V raziskavo smo vključili 50 žensk, starih od 18 do 55 let, ki obiskujejo različne fitnes centre v Ljubljani in njeni okolici. S tehtnico TANITA (Tanita, Innerscan body composition monitor, model BC-545), ki temelji na šest točkovnem merjenju z magnetno impendanco, smo pridobili podatke o telesni teži, kostni masi, mišični masi, deležu maščevja, visceralni maščobi, deležu vode v telesu, dnevni porabi kalorij, tipu telesne sestave in vitalnosti organizma. Z vprašalnikom smo pridobili podatke o nekaterih socialno-demografskih značilnostih žensk, ki se ukvarjajo s fitnes vadbo, dolžini in pogostosti ukvarjanja z vadbo v fitnesu ter uporabi in poznavanju prehranskih dodatkov. Dobljene rezultate smo statistično obdelali s pomočjo programa SPSS, uporabili smo metodo opisne statistike. Rezultati so pokazali, da večina žensk, ki se ukvarja z vadbo v fitnesu, uporablja prehranske dodatke. Večjih razlik v telesni sestavi žensk, ki uživajo prehranske dodatke in tistih, ki jih ne, ni bilo, zato ne moremo potrditi pozitivnega vpliva prehranskih dodatkov na boljšo telesno sestavo. Ugotovili smo, da imajo udeleženke raziskave o prehranskih dodatkih slabo oz. srednje znanje, kar je zanimivo predvsem zaradi tega, ker večina dodatke uporablja. The purpose of our research was to determine how well do females who attend fitness centres know nutritional supplements, how many of them use these supplements and in which way they affect their body structure. The research included 50 females of ages from 18 to 55 who attend various fitness centres in Ljubljana and its surroundings. Using a TANITA scale (Tanita, Innerscan body composition monitor, model BC-545, a six point measurement scale with magnetic impedance), we gathered information about body weight, bone mass, muscle mass, body fat percentage, visceral fat percentage, body water percentage, daily calorie expenditure, body type and organism vitality. The questionnaire gave us information regarding socio-demographic characteristics of females who exercise in fitness centres, frequency and length of fitness workouts and use and knowledge of nutritional supplements. The results were statistically analyzed with the SPSS program. The results showed that most of the subjects do use nutritional supplements. There were no substantial differences found in body structure of women who use nutritional supplements and of those who don’t, therefore we cannot confirm a positive effect of nutritional supplements. It was determined that the subjects have low or moderate knowledge of nutritional supplements which was interesting due to the fact that most of them use nutritional supplements.
