경기 종목에 따른 잠재성 철결핍성 빈혈 양상

Abstract

This study was performed to investigate non-anemic iron deficiency factors of Korea National Rhythmic Gymnasts(n=10), Korea National synchronize swimming players(n=6), elite volley-ball players(n=13). The mean age of the subjects were 16.7±1.83, 18.5±1.37, 16.6±1.12 years old. Their mean carrier were 7.34±2.55, 9.83±1.32, 5.77±1.83 years. Their mean height were 160.28±7.6, 167.83±3.54, 176.21±4.18cm and mean weight were 44.28±4.26, 53.83±2.78, 67.15±4.67kg. Body fat(BF) assessment by skinfold thickness shows that the average percentage BF of subjests are about 12.43±3.07, 22.77±3.10, 21.63±1.42% of body weight. Three-day food records were collected from each subjects and analyzed using a computerized nutrient database. The average daily energy intake were 1,028.66±371.43, 1720.72±592.95, 2995.03±342.44kcal and were 48.25, 142.63, 83.68% of Korean Recommended Daily Allowance(RDA). The rate of the 3 major nutrition(P：F：C) was 13.4：12.9：73.7, 15.4：19.7：64.9, 15.8：14.4：69.7%. It showed that low protein, fat and high carbohydrate intake rate. Also mean iron intakes of the subjects was low and was 32.97, 45.83, 90.15% of Korean RDA. The female players intake less nutrition compare with the daily suggestion. Most hematological iron indices were within low range that was in the iron deficient range. Mean hemoglobin(Hb) level was significantly lower(11.7g/dl) than average level. And iron parameters(Hematocrit, Hct；Total iron binding capacity, TIBC；and serum ferritin) was very low level. The results of the present study suggest that these female players may not be consuming adequate amount of energy yielding nutrients and those that influence bone heath during sports season. Future studies are needed to examine the effects of nutritional status on performance and to develop strategies to improve the nutritional status of these female players.
