The Aim of this study is to determine the effectiveness of using Aquabag Dynamic Neuromuscular Stabilization(DNS) Training on functional movement and postural sway of middle-aged women. A total of 24 middle-aged women participated and were randomly assigned to 2 different groups: n=12 were included in the Aquabag DNS training group while n=12 were included in the control group. The Aquabag DNS training lasted 12weeks(2sessions/week, total=24sessions of approximately 60min/session).
Center Of Pressure(COP) distance, Root Mean Square(RMS), and COP area of each groups were measured by Force plate for evaluating participants' Dynamic balance abilities and Reaching Unilateral Standing(RUS) required to all subjects. After converting collected 2D data to 3D data through Qualisys Track Manager(QTM), movements of all subjects were transformed into 3D models with the Visual 3D and calculated in Excel. For evaluating their functional movements, Functional Movement Screen(FMS) tests were conducted. Then, the descriptive statistics from collected data were computed. The Paird t-test was conducted to compare the pre and post exercise in each group. In addition, the independent t-test to verify differences between the experimental group and the control group was conducted.
The results are as below. There were significant differences in the COP distance(p<.001), RMS(p<.05), COP area and FMS score(p<.001) between pre and post exercise in each group. And significant differences were observed in COP distance(p<.05), RMS(p<.05), COP area(p<.05) and FMS score(p<.05) between groups. The Aquabag DNS training improved a dynamic stability of single-leg standing, a torso stability and a functional movement in Middle-aged women.
These findings showed that the Aquabag DNS training designed in this study is a very useful training methods for trainees who require the posture correction in a safe and effective way regardless of their age or gender.
