This study aims to evaluate the changes in the ultrasonographic thickness of transversus abdominis and internal oblique muscles during bridge with arm extension compared to bridge and abdominal hollowing.
Between March 1, 2019 and March 29, 2019, a total of 30 healthy individuals (15 males, 15 females; mean age: 28.8±8.1 years; range, 21 to 52 years) among hospital staff were included. Thickness of transversus abdominis, internal, and external oblique muscles of the participants were evaluated using ultrasound during four positions (rest, abdominal hollowing, bridge, and bridge with arm extension).
The mean body mass index was 23.8±4.1 kg/m. The thickness of transversus abdominis and internal oblique muscles increased during all positions (p<0.001), compared to rest. The thickness during bridge with arm extension was greater than abdominal hollowing and bridge.
Co-activation of latissimus dorsi and gluteus maximus muscles during abdominal contraction increases the thickness of internal oblique and transversus abdominis muscles greater than abdominal contraction alone or co-activation of gluteus maximus alone. Simultaneous isometric contraction of latissimus dorsi muscle may enhance abdominal muscle function.
本研究旨在评估与桥式运动和收腹动作相比，手臂伸展桥式运动过程中腹横肌和腹内斜肌超声厚度的变化。
2019年3月1日至2019年3月29日，纳入医院工作人员中30名健康个体（15名男性，15名女性；平均年龄：28.8±8.1岁；范围21至52岁）。在四个体位（静息、收腹、桥式运动、手臂伸展桥式运动）期间，使用超声评估参与者的腹横肌、腹内斜肌和腹外斜肌厚度。
平均体重指数为23.8±4.1kg/m。与静息相比，所有体位下腹横肌和腹内斜肌厚度均增加（p<0.001）。手臂伸展桥式运动时的厚度大于收腹动作和桥式运动时的厚度。
腹部收缩时背阔肌和臀大肌的共同激活比单独腹部收缩或单独臀大肌共同激活更能增加腹内斜肌和腹横肌的厚度。背阔肌同时进行等长收缩可能会增强腹部肌肉功能。
