초록

본 연구는 운동을 하지 않는 여자 중학생을 대상으로 걷기운동이 체구성, 체력, 심혈관 기능, 혈청지질, GH, IGF-1 및 Leptin에 미치는 효과를 분석하기 위하여 걷기운동을 12주간 수행한 결과 비만집단과 일반집단 모두 체구성, 체력 심혈관 기능, 혈청지질 및 인슐린 인자에서 긍정적인 변화를 보였으며, 특히 비만집단은 체지방의 감소효과가 컸고, 일반집단은 근육량의 향상에 효과가 컸으며, 두 집단 모두 체력요인의 향상이 있었고 심혈관 기능과 혈청지질 및 인슐린 인자의 변화에도 여러 요인에서 유의한 효과가 있었다. 이러한 결과는 청소년시기에 바쁜 생활패턴에서 걷기운동만으로도 여중생의 체구성과 체력을 정상적으로 유지시킬 수 있는 좋은 운동 프로그램이 될 수 있음을 나타내고 있다. 그러나 이러한 긍정적인 변화를 지속시키기 위해서는 올바른 식습관(diet)과 보다 긴 걷기운동시간이 필요하다. 본 실험의 대상자들 또한 실험기간 중 정해진 운동시간외에 개인적 걷기운동량이 하루 15분정도 증가하였다. 운동추후의 연구에서는 운동기간의 증가와 운동 강도의 증가에 따른 지속적인 변화의 분석을 위한 연구가 필요하다고 생각된다.

The purpose of this study was to investigate the effects of 12-week walking exercise on body composition, physical fitness, cardiovascular function, blood lipids, GH, IGF-1and leptin in obese and normal middle school girls. Participants included 12 pairs of middle school girls who were matched for sex, age and stratified by BMI (Obese Group: BMI$\geq$25.0; Normal Group: BMI<23.0). The variables of all factors were measured in all the subjects before and after the 12-week walking exercise program. The test data were analyzed by paired t-test, and t-test using the SPSS 14.0 statistics package and the alpha level of p<0.05 was set for all tests of significance. Body composition showed a significant difference in both groups, but the variables of physical fitness, cardiovascular function, blood lipids, growth hormone, and leptin did not show a significant difference in the two groups. We conclude that regular and continuous walking exercise improved body composition, physical fitness, cardiovascular function, blood lipids, and insulin factors in both groups. Consequently, these findings suggest that walking exercise will be effective for preventing obesity and improving health-related factors in the middle school girls.
