- Abstract
The aim of this research was to study and evaluate nutrition of Vilnius University female students of 2nd, 3rd and 4th years participating in organised physical activities. We evaluated nutrition of 128 female students of Vilnius University who had chosen „Introduction into PE and healthy lifestyle“ as an optional subject. Method of one day (24 hours) nutrition survey was applied in this research. Chemical composition and energetic value of food ration was counted using tables of chemical composition of nutrition products. Statistical analysis was carried out using software for statistical data processing SPSS v.13. The methods of mathematical statistics were applied for the analysis of research data: arithmetic means (X¯) were calculated and data dispersion was evaluated under standard deviation (S). Pearson's correlation coefficient (r), when p ≤ 0.05, was employed in the calculations aiming to get more accurate data and searching for statistical correlation links among variables. Research data were compared to recommended norms (per day) of nutrients and energy norms. Research results have demonstrated that energetic value obtained by students with food (1696 ± 611 kcal) was too low comparing to recommended (1950 kcal). Energetic food rations values of secondand fourth-year students were particularly low in a number of cases; in individual cases it hardly reached 586 kcal for second-year students and 663 kcal in fourth year students. In main nutrients in female students' nutrition were not balanced. They used too much fat and not enough carbohydrates. Immoderate amount of provided energetic value - consisted of fats (40.2 ± 9.2%), saturated fatty acids (13 ± 47%), linol fatty acid (6.2 ± 3.3 %), mono- and disaccharides (22.3 ± 9.1%); and too small amount - of carbohydrates (45.2 ± 9.9%) which consisted of starch, other polysaccharides and polyunsaturated fatty acids (6.9 ± 3.6) such as non-synthesized linolenic fatty acid (0.4 ± 0.4). Amount of proteins in the daily ration of female students - participants of our study - corresponded to recommended norms per day. Essential amino acids valine, leucine and isoleucine were not balanced in the nutrition of the students in all years of studies. In the ration of second-year students amino acids methionine and lizine were not balanced. In the daily ration of the female students there was a shortage of food rich in starch and other polysaccharides, fibres (different cereal products, breads, fresh fruits and vegetables) and foods rich in proteins (meat, fish, milk products), and thus they do not get enough minerals such as potassium, magnesium, zinc, iron and vitamins A, D, B1, B12, E, PP as well as folic acid. Thus we may conclude that female students attending organised PE activities incorrectly combine physical activity and nutrition.
