Abstract
[Purpose] This study was performed to provide evidence for the therapeutic exercise
approach through a compative analysis of muscle activities according to climbing wall
inclination. [Subjects and Methods] Twentyfour healthy adult subjects without climbing
experience performed static exercises at a therapeutic climbing at with various
inclination angles (0°, 10°, 20°), and the activities of the trunk muscles (rectus
abdominis, obliquus externus abdominis, obliquus internus abdominis, erector spinae) were
measured using surface electromyography (EMG) for 7 seconds. [Results] Significant
differences were found between the inclination angles of 10° and 0°, as well as 20° in the
rectus abdominis, obliquus internus abdominis, right obliquus externus abdominis, and
right erector spinae. [Conclusion] Based on measurements of trunk muscle activity in a
static climbing standing position at different angles, significant changes in muscle
activity appear to be induced at 10 degrees. Therefore, the results appear to provide
clinically relevant evidence.
