Training and assessment of the abdominal and trunk muscles are widely used in the clinical setting. However, it is unknown what types of exercises are most effective in activation of both the global and local stabilizers in these regions.
The purpose of this study was to establish the reliability of a novel clinical screening tool (sling screen) to assess the muscles of the abdomen and trunk. The second aim was to use the clinical screening tool and musculoskeletal ultrasound to compare the effects of a rotary-based exercise program that targets both the global and local muscles to the effects of a traditional exercise program on the activation of the abdominal and trunk muscles.
Double-blind, randomized controlled trial.
Sports medicine facility.
Thirty-one healthy participants were randomly allocated to receive a single-session rotary-based or traditional "core" exercise program.
The participants were assessed at the baseline and immediately postintervention. The primary outcome measures were muscle thickness examined by musculoskeletal ultrasound and clinical examination of muscle activation using a screening tool. The data were collected by blind assessors. Reliability and validity of a clinical screening tool (sling screen) were also assessed.
The analysis of the covariance tests showed a significant increase in oblique thickness for the rotary exercise group. All participants displayed a significant increase in multifidus thickness. The Wilcoxon signed-rank tests revealed a significant increase in clinical assessment scores in the rotary exercise group but not the traditional exercise group. Reliability of the sling screen ranged from moderate to good.
This clinical trial provides evidence that a rotary-based exercise program may be more effective in producing increases in oblique muscle thickness than traditional "core" exercises in young, healthy adults. The sling screen tool was able to identify these muscle thickness changes. Future studies should investigate how these results correlate to injury risk, other populations, and also how to implement the sling screen into clinical practice.
腹部和躯干肌肉的训练和评估在临床环境中被广泛应用。然而，目前尚不清楚哪种类型的运动对于这些区域的整体和局部稳定器的激活最为有效。
本研究的目的是建立一种新的临床筛查工具（吊索筛查）来评估腹部和躯干肌肉的可靠性。第二个目的是使用临床筛查工具和肌肉骨骼超声来比较针对整体和局部肌肉的旋转基础运动方案与传统运动方案对腹部和躯干肌肉激活的影响。
双盲、随机对照试验。
运动医学设施。
31 名健康参与者被随机分配接受单次旋转基础或传统“核心”运动方案。
参与者在基线和干预后立即进行评估。主要结果测量是通过肌肉骨骼超声检查的肌肉厚度和使用筛查工具进行的肌肉激活的临床检查。数据由盲法评估者收集。还评估了临床筛查工具（吊索筛查）的可靠性和有效性。
协方差分析显示，旋转运动组的斜肌厚度显著增加。所有参与者的多裂肌厚度都显著增加。Wilcoxon 符号秩检验显示，旋转运动组的临床评估得分显著增加，但传统运动组没有。吊索筛查的可靠性范围从中等到良好。
这项临床试验提供了证据表明，与传统的“核心”运动相比，旋转基础运动方案可能更有效地增加年轻健康成年人的斜肌厚度。吊索筛查工具能够识别这些肌肉厚度的变化。未来的研究应该调查这些结果如何与受伤风险、其他人群相关，以及如何将吊索筛查纳入临床实践。
