This study, by analyzing the program's effect, attempts to provide basic information on a healthy jogging and circuit-training program for the improvement of physical fitness and body composition for elementary students.
The subjects of this study were twenty students from B City elementary school who were divided into two groups of ten, experimental and control groups. The physical fitness of both groups was pre-tested, and then post-tested after operating the program over the course of eight weeks.
Using the SPSS statistical program for the processing of the pre- and post-test physical fitness data, the differences between groups were t-tested while the differences within the groups were pair t-tested.
The results of this testing suggest the following:
First, with respect to the state of physical fitness, the experimental group showed a statistically significant difference in muscular- cardiopulmonary endurance and flexibility, but showed little improvement in grip muscle strength: no significant difference. The control group showed a decline in grip muscle strength and cardiopulmonary endurance, although there was a small but not significant improvement in muscular- cardiopulmonary endurance and flexibility.
Second, with respect to body composition, both height and weight improved significantly in both groups by the end of the program however, the experimental group showed a significant decline in body fat percentage, BMI (body mass index) and WHR. The control group showed an increase (though not significant) in body fat percentage, BMI and WHR.
These results of study mean that the 8 week program of health jogging and circuit training have positive effect on students' a muscular · cardiopulmonary endurance, flexibility and body composition. Accordingly, this program should be studied and developed continuously to meet students' physical state and need.
