Background. Personality traits associated with one’s health beliefs and expectations constitute a determinant of dietary behaviours. Objective. The aim of the study was to analyse the dietary behaviours of young American football players in the Polish clubs and association thereof with their general self-efficacy level. Materials and Methods. The study included the group of 100 young men (20-30 years of age) who practiced American football on a professional basis in three Polish clubs. The study was based on an original dietary behaviour questionnaire derived from the Swiss Food Pyramid for Athletes and General Self-Efficacy Scale (GSES). Statistical analysis, conducted with Statistica 10.0 PL software, included intergroup comparisons with the Chi-square test. Results. Having at least three meals per day (82%), consumption of such protein products as eggs and/or meat several times per week (68%) and including cereal products in every main meal (67%) turned out to be the most often followed qualitative recommendations of the Swiss Food Pyramid for Athletes in the group of American football players. Other, frequently followed dietary recommendations included remaining on a variable diet (75%), preference to mineral water and other non-sweetened beverages (69%), reduced intake of sweets and salted snacks (65%), energy drinks (64%) and fast food products (60%). The least frequently declared dietary behaviours included consuming recommended amounts of vegetables/fruits (48%) and wholegrain cereal products (45%), and reduced intake of animal fats (42%). Analysis of a relationship between specific dietary behaviours and general self-efficacy level showed that the athletes with higher levels of this trait consumed recommended daily amounts of vegetables (54% vs. 26%, p<0.01) and cereal products (87% vs. 50%, p<0.001), had recommended number of meals per day (96% vs. 70%, p<0.001) and ate regularly (76% vs. 24%, p<0.001) significantly more often than the persons characterized by lower self-efficacy levels. Conclusions. Players with higher general self-efficacy levels adhere to the recommendations of the Swiss Food Pyramid for Athletes to a larger extent than the sportsmen with lower levels of this trait.

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.
