Abstract
|
|
|
Background: Exercise in the quadruped position is performed to improve body and shoulder stability. This study examined the muscle activity of the trunk muscles according to the distance of the weight shift when lifting one leg in the quadruped position.
Methods: Ten healthy 20 to 40 years old males were tested as subjects. All subjects moved their body weight to 0, 5, and 10cm on the opposite side of the leg lifter while maintaining the quadruped position. The surface electrodes recorded the electromyography data during the one leg lifting.
Results: As the weight shift distance was increased, there was a significant difference in muscle activity of both serratus anterior, multifidus and internal oblique muscles (p<.05). Left and right serratus anterior and right internal oblique were most activated when weight shift distance was 0cm (p<.05).
Conclusion: Shoulder and lumbar stabilization exercises should be applied in the absence of a weight shift distance during quadruped exercise.
