본 연구는 초등학생의 잠재된 체력요인 구분 및 면역력 정도를 알아보기 위한 연구로서 체육영재들을 대상으로 ACE 유전자 다형성에 따른 체력과 면역력의 차이를 분석하였다. 본 연구의 대상은 경기도 지역 초등학생 (1, 2, 3학년) 중 체육 영재로 선발 된 50명이었으며, ACE 유전자 다형성 분석을 통하여 II형질 23명(130.60±7.58cm, 28.35±5.62kg), ID형질 19명(128.01±8.00cm, 27.19±5.45kg), DD형질 8명(126.71±9.24cm, 27.70±4.87kg) 3집단으로 분류하였다. 체력요인으로 심폐지구력, 근지구력, 유연성, 평형성, 순발력, 민첩성을 측정하였으며, 혈액 분석 변인으로는 Immunoglobulin G, Immunoglobulin A, Immunoglobulin M 요인을 분석하였다. 자료처리는 ACE 유전자 다형성에 따른 체력 및 면역력의 차이를 알아보기 위해 one-way RG(3) ANOVA를 사용하였으며, 집단 간 통계적 유의차에 따른 주효과 검증은 LSD를 사용하였다. 본 연구의 결과 첫째, ACE 유전자 다형성에 따른 집단간 체력요인의 차이는 심폐지구력, 근지구력, 순발력, 민첩성에서 통계적으로 유의한 차이를 나타내었다. 둘째, 체력변인 중 심폐지구력, 유연성, 평형성 항목에서 II집단이 높은 체력을 나타내었고, 근지구력, 순발력, 민첩성 요인은 DD 집단에서 높은 체력을 나타내었다. 셋째, ACE 유전자 다형성에 따른 면역력의 차이는 모든 변인에서 통계적으로 유의한 차이가 나타나지 않았지만, DD집단에서 Immunoglobulin A가 다소 낮은 결과를 보였다. 위와 같은 결과를 종합해 볼 때, 초등학교 학생들의 ACE 유전자 다형성 분류에 따라서 II형질 소유 아동은 유산소 비율이 높은 운동을, DD 형질은 단발적으로 힘이 사용되는 운동 종목을 제안하고자 한다. 또한, DD 유전형질을 소유한 아동은 Immunoglobulin A가 다소 낮은 결과를 나타내고 있어 다른 형질에 비해 감염에 손상 받기 쉬우므로 외부환경과 훈련에 염두하고 운동을 수행하는 것이 바람직하다고 사료된다.
The purpose of this study was to provide a basic data for growth as sport gifted child through that it were investigated a physical fitness and immumoglobulin levels as a result of analyzing it’s difference according to AEC gene polymorphism. Subjects were participated by fifty(50) elementary school students without special medical history and then they were divided into three groups such as , II 23 person(130.60±7.58cm, 28.35±5.62kg), ID 19 person(128.01±8.00cm, 27.19±5.45kg), and DD 8 person(126.71±9.24cm, 27.70±4.87kg) from AEC gene polymorphism analysis. Physical fitness factors were selected such as cardiorespiratory fitness, muscular endurance, flexibility, balance, muscular power and agility. Also, level of immunity analyzed a immunoglobulin G, A and M. The statistical analysis of this study used One-way RG(3) ANOVA to analysis difference of physical fitness and immunity factors and main effect used LSD as statistically significant difference between groups. First, difference of physical fitness factor between groups as AEC gene polymorphism showed statistically significantly difference at cardiorespiratory fitness, muscular endurance, muscular power and agility. Second, group II was most high result at cardiorespiratory fitness, flexibility, and balance while group DD was most high at muscular endurance, muscular power and agility. Third, difference of immunity factor between groups as AEC gene polymorphism was not significant difference at all factors but the DD group showed a little lower Immunoglobulin A than another groups. Aerobic exercise is suggested to II ACE genetic type, and DD type can suggest the exercise used momentary power. Also, DD type was showed low result at immunoglobulin A. This genetic trait should do exercise carefully because they are getting easily infection from the external environments than other groups.
