[Investigation of actual nutrition and some factors of physical status in rugby players].

Physical status and nutrition and energy value of factual diets of 18 rugby players (15-30 years old) assessed during current medical observation were analyzed. Anthropometric data (height, body mass--BM, waist circumference/ hip circumference index, body mass index--BMI), body composition data and resting metabolic rate by bioimpedance method (analyzer ABC-01 "Medass") were determined. These indices were found to be normal except more high level of BMI due to high levels of lean and skeletal muscle mass, but not a result of obesity. Estimation of factual nutrition based on 1-day feeding (nutrition-screening questionnaire method) has demonstrate that it was not optimal both for energy and nutrition value for this group of physical activity. Energy value ranged from 1889 kcal to 3175 kcal (22.5-35.1 kcal/kg BM/day) with lower carbohydrate intake (46.9%) and higher fat intake (35.8%) were found. Nutrition value ranges: protein--67-144 g (0.71-1.38 kcal/kg BM/day), fat--75-140 g (0.88-1.51 kcal/kg BM/day), carbohydrate--173-420 g (2.17-4.66 kcal/kg BM/day) were observed. The findings suggest the need to pay more attention to in-depth study of dietary intake of athletes to maintain health and to create optimal conditions for a professional sports activities.
