탄성밴드 운동이 지적장애 아동의 건강관련체력과 혈중지질 및 성장관련인자에 미치는 영향

Abstract

This study was carried out to find the effect of elastic band exercise on the health-related physical fitness, blood lipids, and growth factors of the children with mental retardation. For this study, 16 children were recruited from B-gu rehabilitation center for the disabled, and they were residents of B City. The children performed a cycle (1-4 weeks) of exercise program for 50 minutes a day, 3 times a week for 12 weeks with the intensity of 13-15 RPE (moderate intensity). SPSS 18.0 was used for data analysis, paired t-test and two-way repeated measure ANOVA were used for statistical analysis. Significance level was set at .05. The following conclusions were gathered from the study. 1) In within-group comparison before and after elastic band exercise, the exercise group increased the percentage of body fat, fat-free mass, cardiopulmonary endurance, muscular endurance, and flexibility, but no difference was found in muscular strength. The control group did not show any difference in the percentage of body fat, fat-free mass, cardiopulmonary endurance, muscular endurance, and flexibility. 2) In between-group comparison before and after elastic band exercise, a significant difference was found in the percentage of body fat, fat-free mass, cardiopulmonary endurance, muscular endurance, and flexibility (except muscular strength) as the interactive effects of group and time difference. 3) In within-group difference before and after elastic band exercise, the exercise group significantly increased all of TC, TG, HDL-C, and LDL-C. The control group significantly increased TC and TG, but no significant difference was found in HDL-C and LDL-C. 4) In between-group difference before and after elastic band exercise, significant interactive effects of group and time difference were found in TC, TG, and HDL-C, except for LDL-C. 5) In within-group difference before and after elastic band exercise, the exercise group significantly increased all of GH and IGF-1. The control group also increased GH and IGF-1 significantly. 6) In between-group difference before and after elastic band exercise, significant interactive effects of group and time difference were found to be significantly different in GH and IGF-1.

According to the results of this study, the effect of elastic band exercise on health-related physical fitness in the children with mental retardation showed to be positive except for muscular strength. The exercise was also effective for blood lipid factors, and positive changes were found in growth-related factors of both exercise and control group. Due to the characteristics of the disabled children, the assistant teacher’s role was important in this study. Continuous and follow-up studies on the full participation of disabled children are considered to be needed.
