The purpose of this study is to enhance health promotion of sedentary workers by examining the impact of the gravitational accelerate vibration exercise on the range of hip joint motion and the reduction of lower back pain, and suggest appropriate exercise treatment to them. For this study, 30 sedentary workers who had been suffering from lower back pain for more than three months were randomly chosen. They were divided into an experimental group and a control group, and each 15 workers’ body composition, level of pain, and the range of hip joint motion were measured. For the experimental group, a 12 week exercise program to reduce lower back pain and improve the range of hip joint motion was applied, while any treatment was applied to the control group. Then, the post-measurement was conducted after 12 weeks. The collected data were analyzed using SPSS 23.0 and the mean and standard deviation were obtained. Also, a paired t-test was performed to examine the difference of pre- and post-analysis in the groups, and an independent sample t-test was performed to examine the difference between the groups. The results revealed that there was a decrease in a statistically significant mean difference (p < 0.05) of body fat in the experimental group. Also, there was an increase in statistically significant mean difference(p < 0.001) of the range of hip joint motion in the experimental group, whereas there was a decrease in the controlled group. In addition, there existed a decrease in significant difference (p < 0.001) of VAS. Also, there was a decrease in significant difference (p < 0.001) of KODI in the experimental group, whereas there was an increase in the controlled group. In conclusion, the gravitational accelerate vibration exercise had a positive effect on reducing body fat of sedentary workers, and it was effective in increasing the range of hip joint motion. Therefore, the gravitational accelerate vibration exercise can be seen as an effective treatment so as to increase the range of hip joint motion and reduce lower back pain. Therefore, this study is meaningful in stating that the gravitational accelerate vibration exercise is an effective treatment for the range of hip joint motion and lower back pain.
