Abstract: | Purpose] This study evaluated the effects of bridge exercise on trunk core muscle
activity with respect to sling height and hip joint abduction and adduction. Subjects]
Fifteen healthy adult males participated. Methods] In the bridge exercise, the height of
the sling was set low or high during hip joint abduction and adduction. Electromyography
was used to compare the differences between the muscle activities of the transverse
abdominis, rectus abdominis, and erector spinae muscles. Results] The muscle activities
of the transverse abdominis, rectus abdominis, and erector spinae were significantly
higher in the high sling position. Furthermore, the activities of the transverse abdominis
and erector spinae were significantly higher during hip joint adduction than abduction
regardless of sling height. Conclusion] A high sling height is the most effective
intervention for increasing the muscle activities of the transverse abdominis and erector
spinae muscles during hip joint adduction in a bridge exercise.Key words: Bridge exercise, Trunk core muscle, Sling |
