This study aims to examine the current situation of run-walk training of elementary school students on their health-related physical fitness and to compare the difference and correlation in health-related physical fitness after run-walk training. In addition, the study finds that guiding students to conduct a proper amount of exercise will improve their health-related physical fitness. This study selected students from the Gong cheng Elementary School as the parent group, who were sampled using tiered and random methods, and measured by ?Three-Day Physical Activity Memory Record? and ?Health-Related Physical Fitness Inspection.? The data obtained were analyzed by the statistical method of covariance analysis. The following important conclusions are drawn from this study: 1. In the aspect of cardio respiratory fitness, students in the experimental group spent more time in run-walk training than those in the control group, hence their cardio respiratory fitness improved. 2. In the aspect of muscular strength and endurance, the experimental group showed a trend of improvement in the standing long jump and 800 m run-walk in contrast with the control group. This indicates that the run-walk exercise can improve elementary school students? muscular strength and endurance. 3. In the aspect of flexibility, the run-walk exercises led to different study results because the effect was different owing to the differences in the number of samples and experimental objectives. This study draws the conclusion that physical activity is significantly related to health-related physical fitness. Hence, properly increasing students? involvement in physical activities will definitely and effectively increase their participation in physical activity and health-related physical fitness.
