The purpose of this study is to verify the effect of spinal stabilization exercises using abdominal bracing technique for 50 min, conducted three times a week for 8 weeks for the female college students on their lumbar muscle strength and pulmonary function. The subjects were 18 female students in college located in C city, Korea who did not work out. Specifically, they divided into three groups; Abdominal bracing with spinal stabilization exercises (BSE, n=6), Spinal stabilization exercises (BSE, n=6) and Control group (CON, n=6). BSE Group received additional education of bracing technique before exercise so that they could carry out bracing technique during the spinal stabilization exercise. The was measured by Biodex System pro Ⅲ and the pulmonary function was measured by Spirometer. The flexion and extension exercise were conducted 5 times at angular speed of 60°/sec, 10 times at 90°/sec and 15 times at 120°/sec to investigate the muscular function of lumbar joint and moreover, the pre-test and post-test of the peak torque/body weight and total work/body weight and extension/flexion ratio was carried out. And for the pulmonary function, the pre-test and post-test of force vital capacity (FVC), forced expiratory volume in 1 second (FEF1.0), percentage of forced expiratory volume in 1 second (FEF1%: flow; PEF) and the forced expiratory flow (25-75%; FEF25-75%) was conducted. Furthermore, Repeated measurement ANOVA and the paired t-test were conducted to reveal the difference according to the 8 weeks workout program. The significance level (α) was set at 0.05.
To summarize the research results, the interaction effect was significant in F(2)=6.474, p=.009, according to the time by group for the lumbar extensor strength at the 90°/sec by weight and also, BSE Group and SE Group increased while the CON Group decreased. For the difference between groups, Moreover, there were significant increase in the lumbar flexor muscle at 60°/sec(t(5)=-3.468, p=.018), lumbar extensor strength at 60°/sec(t(5)=-3.989, p=.010), lumbar flexor muscle at 120°/sec(t(5)=-3.026, p=.029) and the lumbar flexor muscle at 120°/sec(t(5)=-2.887, p=.034) only in BSE Group. The difference between rate of extensor muscle/flexor muscle was statistically significant in the interaction effect of time and group (F(2)=4.440, p=.031). Despite of increase in BSE Group, both SE and CNO groups decreased. The variables that measures the pulmonary function increased numerically in the group where operated the workout program but there was no statistically significant difference.
This research investigated that abdominal bracing spinal stabilization exercise could significantly increase the lumbar spine stabilization of female college students. Therefore, it’s expected to have more positive result for the long-term work out and the further research–which is more effective–will be conducted, based on the results of this research.
