Purpose: The purpose of this study was to investigate the effect of unicycle exercise on trunk musclethickness.
Methods: A total of 30 university students were randomly assigned to the experimental group (n=15) and thecontrol group (n=15). In the experimental group, unicycle exercise was performed for 50 minutes, 3 timesper week, and a total of 10 weeks. In the control group, trunk muscle strengthening exercises were performedduring the same period. To investigate the trunk muscle thickness of the subjects, ultrasound imaging wasused to measure the external oblique muscle, internal oblique muscle, transverse abdominis, and multifidus.
Results: As a result, it was found that there was a significant difference between groups and between preandpost-tests in the external oblique , transverse abdominis, and multifidus muscles. In the internal obliquemuscle, there was a significant difference between pre- and post-tests, but not between groups.
Conclusion: In conclusion, this study demonstrated that the unicycle exercise increased trunk musclethickness. This result can be suggested as basic data for the effect of the unicycle exercise on abdominaland back muscle contraction.
