| Summary: | [Purpose] The current study investigated the influence of backpack carrying on the dorsal and ventral sides on the sway of standing center of pressure (COP) and trunk muscle activities. [Participants and Methods] The subjects were 25 young adult men. The muscle activities of the upper and lower rectus abdominis muscles, obliquus externus abdominis muscles, lumber paraspinals muscles and COP sway were evaluated under five conditions: not carrying a backpack, carrying a backpack weighing 5% and 10% of body weight on the ventral side, and carrying a backpack weighing 5% and 10% of body weight on the dorsal side. [Results] The muscle activity of the lumber paraspinals muscles was significantly higher when carrying a backpack weighing 5% and 10% of body weight on the ventral side compared to not carrying a backpack and carrying a backpack weighing 5% and 10% of body weight on the dorsal side. [Conclusion] The results suggest that carrying a backpack on the ventral side may lead to an increase in the burden on the lower back due to the generation of lumbar back muscle tension. |
