Abstract
|
|
|
Purpose: This study was conducted in order to influence the muscle strength of an serratus anterior, deltoid and triceps brachii depending on the left or right leg lifting during push up in the crawling position.
Design: Cross-sectional study.
Methods: 20 subjects participated in the study, Subjects perform 10 Push-up holding the right-left leg lifting in the crawling position according to the EMG sound that comes out every 3 seconds. Six muscles were measured in the right and left deltoid, triceps brachii and serratus anterior.
Results: There was no significantly different in deltoid and triceps brachii activity in the lifted position compared to the unlifted position, but there was significantly difference in serratus anterior.
Conclusion: In the crawling position, push up with the leg lifting increased the muscle activity of the serratus anterior Serratus anterior was higher than other muscle activity.
