The purpose of this study is to investigate the effect of exercise programs according to various music tempo on pain, posture, and function of automobile parts manufacturing workers. Design: Two-group pretest-posttest design. Methods: This study was an exercise program tailored to the prevention and treatment of musculoskeletal diseases were performed for a total of 4 weeks and 3 times a week for 60 minutes. The exercise program consisted of customized exercises according to the characteristics of the subject's musculoskeletal system. The subject provided music during the exercise program, and the group who applied the fast tempo music listened to the music of 120~140 bpm, and the group who applied the slow tempo music listened to the music of the low tempo of 60~80 bpm. Results: Significant differences were found in pain and physical function before and after the fast tempo music group and the slow tempo music group (p<0.01). However, there was a significant difference in posture characteristics only in the fast tempo music group (p<0.01). In terms of pain, physical function, and posture characteristics, the fast tempo music group showed significant improvement compared to the slow music tempo group (p<0.05). Conclusions: A customized exercise program using fast-tempo music and slow-tempo music to workers in the automobile parts manufacturing industry, significant differences in pain, physical function, and posture characteristics applied with fast-tempo music were found. In the future, applying an exercise program with a fast tempo is expected to help improve musculoskeletal disorders.
