We evaluated the trunk abdominal muscle thickness while performing different exercises to identify the most effective training and to investigate the subjective difficulty associated with exercising. Twenty-eight men (mean age: 21.6 ± 0.9 years) without orthopedic diseases were enrolled. Ultrasonic imaging was used to measure the thickness of the transversus abdominis (TA), internal oblique, and external oblique muscles while at rest and while performing the abdominal draw-in maneuver and abdominal bracing. Measurements were made in the supine and sitting positions, and the subjective difficulty in performing each exercise was examined using a 5-level evaluation scale. The TA and internal oblique muscle thicknesses were significantly greater during the abdominal draw-in maneuver (ADIM) than during bracing or resting, in the supine and sitting positions. The subjective difficulty of abdominal bracing (AB) was graded significantly higher than that of ADIM. Additionally, a correlation between subjective difficulty and muscle thickness was found for the TA and IO. Our results may contribute to the choice of more effective exercises for spinal stability.
我们评估了在进行不同运动时躯干腹部肌肉的厚度，以确定最有效的训练方法，并研究与运动相关的主观难度。招募了28名无骨科疾病的男性（平均年龄：21.6±0.9岁）。使用超声成像测量腹横肌（TA）、腹内斜肌和腹外斜肌在休息时以及进行收腹动作和腹部支撑时的厚度。在仰卧位和坐位进行测量，并使用5级评估量表检查进行每项运动的主观难度。在仰卧位和坐位时，收腹动作（ADIM）期间TA和腹内斜肌的厚度明显大于支撑或休息时。腹部支撑（AB）的主观难度评分明显高于ADIM。此外，发现TA和腹内斜肌的主观难度与肌肉厚度之间存在相关性。我们的结果可能有助于选择更有效的运动来维持脊柱稳定性。
