A Case Study on the Analytic Research of the Effect of New-Exercise on Elementary School Students? Physical Fitness

[[abstract]]The research intended to discuss the effect of the second version new-exercise on the physical fitness of the upper-level elementary school students. The research was aimed at the fifth grade students (male sample: 28, female sample:28) of He-Ping Elementary School in Ping-Dong city. The students were divided into one experimental group (the number of male and female is 14 each) and one antithetic group (the number of male and female is 14 each) in S formation according to gender and pretest results. The experimental group received the second version new-exercise training for two circuits a time, three times a week, with duration of twelve weeks. The antithetic group maintained regular lifestyle and received no training, but normal participation sports curriculum. Both groups received physical fitness test before and after the experiment. The content of physical fitness test includes: 1. Body Composition (Body Mass Index) 2. Flexibility (sit and reach) 3. Explosive force (stand jumping) 4. Muscle endurance (one-minute sit up) 5. Heart and lung staying power (800m jogging). After the experiment, the homogeneity between groups was tested by independent sample ANOVA; the progress range was tested by interdependent sample t. The level of significance ? III @.05. The test result indicated that the upper-level elementary school students who received the second version new-exercise had made significant progress in flexibility, explosive force, muscle endurance and heart and lung staying power except in body composition. Besides, significant difference existed in explosive force, muscle endurance and heart and lung staying power between trained students and non-trained students. The research verified that the second version new-exercise could apparently improve the flexibility, explosive force, muscle endurance and heart and lung staying power of the upper-level elementary school students. Therefore, it is suggested that all elementary schools promoted the exercise program actively to improve the health condition of students and thus developed their body and mind
