Comparison of characteristics and nutritional adequacy of junior short distance and medium and long distance athletes
This study analyzed characteristics and nutrient intake of junior track athletes according to their sports event. Total 107 junior track athletes(62 boys, 45 girls) aged 11 to 15 years, were classified into short distance male runners(SM, n=34), medium and long distance male runners(MLM, n=28), short distance female runners(SF, n=25) and medium and long distance female runners(MLF, n=20). MLM exhibited significantly lower in % body fat than SM(p<.01). In addition, MLF showed significantly lower in parameters including height(p<.05), weight(p<.05) and lean body mass index(p<.01) than SF. The ratio of macronutrient intake appeared out of the appropriate range in all groups. Furthermore, energy, Ca of the nutritional adequacy ratio(NAR) in the all groups were assessed not adequacy. There were significantly correlation energy requirement with NAR vitamin B1 (r=.44, p<.05) in SM, NAR protein(r=.49, p<.05), NAR vitamin B1(r=.49, p<.05) in MLM, NAR energy(r=-.44, p<.05), NAR vitamin A(r=-.44, p<.05), NAR vitamin B2(r=-.56, p<.01) in SF, and NAR Ca(r=.60, p<.01), NAR P(r=.54, p<.01) in MLF. These results indicate that the all group's dietary energy and Ca intake were not adequate for the junior track athletes. Therefore, optimal athletic nutritional planning based on individual energy requirement and nutritional adequacy of dietary intake is needed to enhance athletic health and competition in Korean juvenile track athletes.
Key words: junior athlete, physical characteristic, estimated energy requirement, nutritional adequacy ratio
