TI  - Association between general self-efficacy level and use of dietary supplements in 
      the group of American football players.
PG  - 31-6
AB  - BACKGROUND: Increased nutritional demands of athletes should be covered with a 
      variable well-balanced diet, supported by dietary supplements stimulating 
      synthesis of energy, development of muscle mass and strength, and improving 
      physical capacity. OBJECTIVE: The aim of this study was to analyze an association 
      between the level of general self-efficacy and dietary supplement use among 
      Polish athletes practicing American football on a competitive basis. MATERIAL AND 
      METHODS: The study included the group of 100 athletes (20-30 years of age, mean 
      24.27+/-2.76 years) who practiced American football on a competitive basis. The 
      popularity of various dietary supplements was determined with an original survey, 
      and the level of general self-efficacy with General Self-Efficacy Scale (GSES) by 
      Schwarzer et al. Statistical analysis, conducted with Statistica 10.0 PL 
      software, included intergroup comparisons with the Chi-square test. RESULTS: 
      Isotonic drinks (74%), vitamin (65%) and mineral supplements (50%) and protein 
      concentrates (53%) turned out to be the most popular ergogenic supplements among 
      the American footballers. The group of less popular supplements included caffeine 
      and/or guarana (44%), joint supporting supplements (40%), BCAA amino acids (39%), 
      creatine (36%), carbohydrate concentrates (30%) and omega-3 fatty acids (30%). 
      Analysis of a relationship between the popularity of ergogenic supplements and 
      general self-efficacy showed that the athletes presenting with lower levels of 
      this trait used multivitamin supplements significantly more often than did the 
      persons characterized by lower self-efficacy levels (p<0.05). CONCLUSIONS: The 
      popularity of some dietary supplements varied depending on the general 
      self-efficacy level of the athletes; the popularity of vitamins was significantly 
      higher among the sportsmen who presented with lower levels of this trait.
