| Abstract: | The purpose of this study is rope skipping exercise intervention to understand the health and fitness in junior high school students with mental retardation, the variations of the percentage of body fat and blood biochemical indicators. In this study, using random sampling, 16 aged 12-14 years with mild mental retardation students in Nantou County,. divided into experimental group and control group, and each group had eight junior high students.Before and after the experiment, the experimental group and control group would do the test of health fitness capacity, body fat rate, forearm venous blood detection. The data obtained paired samples t test and independent sample t-test analysis and comparison of two groups of subjects in the health body fitness, percentage of body fat and blood biochemical indicators in magnitude whether statistically significant difference, significance level（p <.05）. The results were as follows:（a）the two groups through the paired sample t-test analysis of the two groups before and after the measured difference in the results, they showed that the lower back flexibility, abdominal muscle endurance, cardiorespiratory endurance, height, percentage of body fat and other health-related fitness to significantly improve cholesterol reach the level of significance;（b）independent sample t-test analysis and found that the experimental group, the lower back flexibility, abdominal muscle endurance, cardiorespiratory endurance, height, percentage of body fat and other health and fitness to achieve significantly improve cholesterol, blood glucose reached significantly lower. The conclusions of this study found that 18 weeks of rope skipping exercise programs can enhance health-related fitness of students with intellectual disabilities to promote height growth, reduce the percentage of body fat and improve blood biochemical indicators. |
