Purpose: This study was conducted to find out the immediate effect on dynamic balance through Abdominal hollowing exercise and Abdominal bracing exercise. Method: 90 healthy male and female students in their 20s were surveyed and measured using Y-balance test and Functional reach test. Result: In the dynamic balance Test between groups, there was a statistically significant difference between the group that performed Abdominal hollowing exercise and the control group. Conclusion: Although both representative spinal stabilization exercises Abdominal hollowing exercise and Abdominal bracing exercise are meaningful in increasing dynamic equilibrium, it is difficult to suggest that any method is more effective in terms of immediate effects.

Lumbar stabilization exercise is a popular exercise method in recent clinicians, as it strengthens muscles around the spine and abdominal muscles, but there is a lack of research on the effects of pulmonary function and respiratory pressure. So, this study examined whether abdominal bracing exercise, a typical lumbar stabilization exercise, was effective in pulmonary function and respiratory pressure. In this study, a total of 20's 40 subjects were recruited and randomly divided into an abdominal bracing exercise group(n=20) and control group(n=20). Abdominal exercise group underwent 25 minutes of exercise. Pulmonary function and respiratory pressure values were measured to analyze respiratory function. As a results of the experimental group, there were significant improvements in FVC, FEV1, PEF and MEP(p<.05) and there was a significant difference in the comparison between groups, except the MIP. These results suggest that abdominal bracing exercise can be presented as effective exercises to improve respiratory function.

The purpose of this study was to investigated the muscle activity difference of lower extremity by abdominal co-contractive activation. 30 healthy women without pain in the low back and lower extremity were conducted. Muscle activities of lower extremity were measured with the active straight leg raise (ASLR) in 20cm raised from the floor without bending the knee at rest, abdominal drawing-in maneuver (ADIM) and abdominal bracing maneuver (ABM), respectively. Hip adductor longus (HadL), rectus femoris (RF), and biceps femoris (BF) muscle activity in the Abdominal bracing maneuver were statistically significantly higher, also gluteus medius (Gmed) and tibialis anterior (TA) muscle activity in the ADIM were higher. We provide the evidence to the positive effects of individual abdominal co-contractive activation training which can enhance postural stability and lower extremity strengthening with volitional preemptive abdominal contraction.
