The Effects of a 15-Week Exercise Program on the Kookmin Physical Fitness 100 Test Results among Noncommissioned Officer (NCO) Studies Students

This study analyzed the effects of a 15-week exercise program on Kookmin Physical Fitness 100 (KPF100) test results, focusing on pre- and post-changes. The participants consisted of 30 students enrolled in the Department of Noncommissioned Officer (NCO) Studies at P University, located in Gyeongbuk. They were divided into an experimental group (15 students: 11 males, 4 females) and a control group (15 students: 9 males, 6 females). A T-test was conducted for the analysis. First, the indicators of physical composition, such as height and weight, showed no statistically significant differences between pre- and post-measurements in both the experimental and control groups (p > .05). Second, in the experimental group, both left-hand and right-hand grip strength (muscular strength) showed significant improvements between pre- and post-measurements (p < .001). Third, sit-and-reach (flexibility) significantly improved in the experimental group (p < .01). Fourth, cross sit-ups (muscular endurance) showed significant improvements in the experimental group (p < .01). Fifth, the number of shuttle runs and VO2Max (cardiopulmonary endurance) significantly improved in the experimental group (p < .01). Sixth, the 10m 4-round shuttle run (agility) showed significant improvements in the experimental group (p < .05). Finally, the standing long jump (explosive power) demonstrated statistically significant differences in the post-measurements between the experimental and control groups (p < .05), but neither group showed significant pre- to post-changes. Overall, the KPF100 results revealed significant improvements across all eight fitness indicators in the experimental group, while no significant changes were observed in the control group. These findings confirm that the 15-week exercise program had a positive impact on the participants' physical fitness.
