Low-back pain is a common health problem in older adult women. Due to various health problems, they cannot continue the use of medications for low-back pain. Recently, specific exercise training are considered as more promising and widely used interventions for low-back pain. However, participation in exercise training remains low among older adult women. The main reason is that these training cause discomfort to other parts of the body due to which they quit the training in its early stage. The purpose of this study is to examine the effect of specific exercise training on low-back pain intensity and overall body parts discomfort. A group-based training for muscles around the spine was arranged in a martial art club. An empirical study with 8 older adult women was conducted for the duration of five weeks. The findings showed a significant difference in the pain intensity and body parts discomfort over the specified duration. Body parts discomfort score was gradually and relatively decreased along with the pain intensity score. The findings revealed that the pain intensity and overall all body parts discomfort remain unchanged in the first and second weeks of the exercise training. However, the pain intensity and body parts discomfort was influenced in the later weeks. This study suggests that exercise training should be strategized to encourage devotion, enable group-based exercise activities, and educate self-efficacy for exercise training.
