Nutrition and anthropometric changes of adolescents girls after nutrition lecture and aerobic gymnastic program

The aim: to assess the nutrition and anthropometric changes of adolescent girls after a nutritional lecture and aerobic gymnastic program. The research problem: The formation of eating habits in childhood and adolescence is usually preserved also in adulthood. Adequate eating habits and physical activity in adolescence are among the most important health determinants. People who choose dance as a form of physical activity tends not to have problems with overweight or obesity. This kind of exercise helps to change not only body composition but also improves mood and self-confidence (Netz, Lidor, 2003; Williams et al., 2006). The peculiarities of lifestyle formed during adolescence have a direct influence on later quality of life. However, modern literature lacks knowledge about adolescent eating habits and health effects. It is not clear what forms of physical activity are the most effective in preventing overweight and obesity, what intensity and frequency of physical activity is appropriate for overweight and obesity reduction. The mehods of the paper: • Analysis of scientific literature; • Questionnaire; • Nutrition lecture; • Regular aerobic gymnastics for teenagers; • Anthropometric measurements; • Pulse measurement • Mathematical – statistical data analysis. Research questions: 1. What is the effect of preventive nutrition lecture on adolescent girls' eating habits? 2. What is the effect and feedback of aerobic gymnastics practice for girls? Hypotesis: 1. After preventive nutritional lecture, eating habits of the subjects will improve. 2. Aerobic workout is a great way to change your body composition and body weight (Williams, Morton, 1986; Williford et al., 1989). Based on these studies, we assume that aerobic gymnastics program will be more effective with a preventive nutritional lecture. Results: after the training program, the anthropometric data did not change statistically significantly (p> 0,05). Heart rate was 129,6 tv./min. The intensity of exercise was in the fat burning area. The number of women doing sports 2-3 times per week increased from 46,9 % to 84,4 % (p<0.05), there was also a tendency to exercise at 4-6 times per week. After nutritional lecture and training program, the nutrition of the girls showed an improvement tendency. The number of participants who ate fish or poultry for 5-7 days a week increased by 37.4 % (p<0.05). The number of participants who ate snacks while watching TV by 1-4 times per week decreased by 21.8 % (p<0.05). The number of participants who ate snacks while working or playing with computer less than 1 time per week increased by 18,7 % (p<0.05). The number of participants who ate snacks while working or playing with computer by 1-4 times per week decreased by 18,7 % (p
