Prolonged sitting can lead to fatigue in the trunk muscles, as the deep trunk muscles remain in a shortened state during sitting postures. Insufficient activity of the deep muscles reduces muscular support for the spine, putting pressure on the spinal structure and consequently leading to muscle stiffness and low back pain (LBP). This study aims to investigate the benefits of foam roller relaxation exercise interventions in alleviating lower back muscle stiffness in sedentary workers. Methods: The study recruited 16 sedentary workers with lower back tightness. The Oswestry Disability Index was used to assess the impact of low back pain on participants' daily activities. Joint range of motion was measured before sitting, after 30 minutes of sitting, and after a 5-minute foam roller relaxation exercise intervention. An inclinometer was used to measure lumbar flexion and extension range, while a goniometer measured lumbar rotation range. This assessed whether sitting affected joint range of motion and if the 5-minute foam roller intervention after 30 minutes of sitting influenced range of motion. Data were analyzed using SPSS 23.0, with ANOVA comparing joint range of motion changes before and after sitting and the foam roller intervention. Significance was set at α = .05. Results: After 30 minutes of sitting, participants showed no significant changes in lumbar flexion, extension, or rotation range of motion. Following the 5-minute foam roller intervention after sitting, there were also no significant changes in lumbar flexion, extension, or rotation range. Conclusion: As foam rollers are readily available and easy to use without assistance, sedentary workers are still recommended to incorporate foam roller exercises during work breaks as an active relaxation approach to counter potential decreases in lumbar range of motion caused by prolonged sitting.久坐活動度滾筒SedentaryRange of motionFoam roller學術論文
