본 연구는 스텝 에어로빅 운동이 지적장애학생들의 신체구성에 어떤 변화를 주는지 탐색하는데 그 목적을 두었다. 이를 위해 경기도 소재 S특수학교 고등부 학생 4명을 대상으로 8주 동안 주 3회, 매회 40분간 스텝 에어로빅 운동을 실시하였고, 사전검사와 사후 검사를 통해 개인별 신체구성(체중, 골격근량, 체지방량, 체지방률) 수치 변화를 측정하였다. 연구결과, 첫째, 개인별 차이는 있으나 신체구성 요인 중 골격근량이 가장 많이 증가하였다. 둘째, 신체구성 요인 중 체중, 체지방량과 체지방률은 감소하는 경향을 보이나, 체중의 경우 학생A는 증가하였고 체지방률의 경우 학생B는 변화가 없었다. 이 같은 결과를 종합해 볼 때, 스텝 에어로빅 운동은 지적장애학생들의 신체구성에 긍정적인 영향을 미치는 것으로 결론 맺을 수 있다.

This study aims to investigate to what extent it would have an impact on the change in body composition of the students with intellectual disabilities when they did a 40-minute step aerobics exercise three times a week for eight weeks. The subject of this study were 4 high school students from S Special Education School at Kyeonggi-do and an step aerobics exercise was progressed 24 times from March to April in 2010. In order to verify the effect of step aerobics exercise, comparing the changes in individual figure by conducting a pre-test and a post-test. The findings were as follows; First, there were individual differences, but skeletal muscle mass increased most among the body composition factors. Eight weeks after all the students involved practiced a step aerobics exercise program, skeletal muscle mass had a huge increase. Meanwhile, among the students, student B changed most. Second, eight weeks after performing the step aerobics exercise program, students weight, body fat mass and percent body fat decreased as a whole, but students A had a slight increase in weight, whereas students B had no changes in percent body fat. Seen from the adove findings, it has been demonstrated that the step aerobics exercise had a positive influence on the body composition of students with intellectual disabilities.
