The aim of the study is to assess the body composition and nutritional behavior of American football players.Materials and methods: The study was conducted among 46 participants from the American football club ‘Towers Opole’. They were split into 2 groups, senior (n = 31) and junior (n = 15). The following measurements were taken: height, weight, body composition (body fat – BF, fat mass – FM, fat free mass – FFM, muscle mass – MM, total body water – TBW) and body mass index (BMI). An evaluation of nutritional behavior through the author’s questionnaire was also conducted.Results: Seniors compared to juniors had – body height (BH):183.1 cm vs. 174.7 cm (p < 0.01), body weight (BW): 94.5 kg vs. 81.6 kg(p < 0,01), BMI: 28 kg/m2 vs. 26.5 kg/m2 (ns), BF: 21.9% vs. 20.9% (ns),FM: 20.8 kg vs. 17.6 kg (ns), FFM: 74.9 kg vs. 66 kg (p<0.01), MM: 71.6 kg vs. 62.6 kg (p < 0.01), TBW: 56.6% vs. 57.9% (ns).The analysis of eating behavior showed that seniors consumed meat and cold cuts every day significantly more often than juniors – 66.7% vs. 28.6% (p < 0.01), they consumed cheeses as well as cream and blue cheese more often – 99.33% vs. 71.43%(p < 0.05), they mainly supplemented liquids with mineral water –63.33% vs. 14.29% (p > 0.05), and occasionally or not at all with energy drinks – 83.33% vs. 50.00% (p < 0.05).Conclusions: Seniors have higher values of somatic variables than juniors. The prevalence of normal eating habits among seniors and juniors is at a similar level, although the group of seniors had more favorable eating habits than the juniors.
