The purpose of this study was to find out how each bag affects the muscle activity of the upper trapezius and erector spinae muscles when walking with a backpack and a shoulder bag. The study subjects were 25, and 17 males and 8 females were recruited. After walking from the 1st to the 6th floor with a backpack and a shoulder bag weighing 10% of the person's weight, walking 10m marked on the laboratory floor was performed. Surface electromyography was used to determine the muscle activity of both dorsal and vertebral pectoral muscles, and a pain sensor was used to determine the degree of pain. With PASW 18, the paired sample t test and one-way analysis of variance were used, and the Bonferroni correction was used for the post-test. There was a significant difference in the activity of the left and right muscles of the upper trapezius when wearing a shoulder bag and the difference in activity of the left and right muscles of the upper trapezius without wearing a bag. When worn, there was also a significant difference in the activity of the left and right muscles of the upper trapezius. There was no significant difference in the activity of the left and right muscles of the erector spinae muscle when the bag was not worn, and when the backpack and shoulder bag were worn. In addition, the erector spinae muscle showed consistently high muscle activity, unlike the upper trapezius, which means continuous muscle contraction of the erector spinae, which is a factor that can increase muscle fatigue. Therefore, it should be strengthened with a focus on the erect vertebrae rather than the upper trapezius. The results of this study inform those who wear shoulder bags that shoulder bags cause an imbalance in muscle activity of the upper trapezius muscle and may cause musculoskeletal problems. It is recommended to wear a backpack rather than a shoulder bag, and it will help to prevent the imbalance of the body.
