While the presence of lumbopelvic-hip stabilization has been provided as an importance component of the intra-abdominal pressure and dynamic spinal stabilization prior to movement, no previous study has investigated the effects in nonsymptomatic adults. This study investigated neuromuscular mechanisms and effects by comparing the natural core stabilization (NCS), abdominal bracing stabilization (ABS), and coordinated core stabilization (CCS) techniques in nonsymptomatic adults during lifting movement. A convenience sample of 40 nonsymptomatic adults (mean ± standard deviation, 27.13±3.82; 27 males, 13 females) were randomized into the NCS, ABS, and CCS techniques during lifting movement. The clinical outcomes included the deep and local (transverse abdominis (TrA), internal oblique (IO), and gluteus maximus (Gmax)) and superficial and global muscle (thoracic erector spinae (TES), lumbar erector spinae (LES), and external oblique (EO)) activation and balance ratios (IO/LES and Gmax/LES) and onset time co-activation ratios (IO/LES and Gmax/LES). One-way repeated-measures analysis of variance (ANOVA) and Bonferroni correction revealed that the IO/LES and Gmax/LES balance and activation ratios were greater in CCS than in NCS and ABS. The onset time co-activation ratio was improved in CCS as compared with NCS and ABS, and ABS dropped equally inversely to NCS. Our results provide novel therapeutic evidence that CCS-based lifting movement is more balanced or coordinated in terms of neuromuscular control than the other techniques and may be used as an alternative exercise for core stabilization.

提举运动期间核心稳定对躯干和髋部肌肉活动的神经肌肉机制和影响

虽然腰骨盆髋关节稳定的存在已作为腹内压和运动前动态脊柱稳定的重要组成部分，但之前没有研究调查过无症状成人的影响。本研究通过比较无症状成人在举重运动期间的自然核心稳定 (NCS)、腹部支撑稳定 (ABS) 和协调核心稳定 (CCS) 技术来调查神经肌肉机制和效果。40 名无症状成人的便利样本（平均±标准差，27.13±3.82; 27 名男性，13 名女性）在举重运动过程中被随机分为 NCS、ABS 和 CCS 技术。临床结果包括深部和局部（腹横肌 (TrA)、腹内斜肌 (IO) 和臀大肌 (Gmax)）以及浅表和全身肌肉（胸竖脊肌 (TES)、腰椎竖脊肌 (LES) 和外部斜（EO））激活和平衡比率（IO / LES和Gmax / LES）和起始时间共激活比率（IO / LES和Gmax / LES）。单向重复测量方差分析 (ANOVA) 和 Bonferroni 校正显示，CCS 中的 IO/LES 和 Gmax/LES 平衡和激活比率高于 NCS 和 ABS。与 NCS 和 ABS 相比，CCS 的起始时间共激活率有所提高，并且 ABS 与 NCS 的下降趋势相同。
