Controlled cohort repeated-measures experimental design.
To determine if a neuromuscular training program (NMTP) focused on core stability and lower extremity strength would affect performance on the star excursion balance test (SEBT). We hypothesized that NMTP would improve SEBT performance in the experimental group and there would be no side-to-side differences in either group.
The SEBT is a functional screening tool that is used to assess dynamic stability, monitor rehabilitation progress, assess deficits following an injury, and identify athletes at high risk for lower extremity injury. The SEBT requires lower extremity coordination, balance, flexibility, and strength.
Twenty uninjured female soccer players (13 experimental, 7 control) participated. Players trained together as a team, so group allocation was not randomized. The SEBT was administered prior to and following 8 weeks of NMTP in the experimental group and 8 weeks of no NMTP in the control group. A 3-way mixed-model ANOVA was used to determine the effect of group (experimental versus control), training (pretraining versus posttraining), and limb (right versus left).
After participation in a NMTP, subjects demonstrated a significant improvement in the SEBT composite score (mean ± SD) on the right limb (pretraining, 96.4% ± 11.7%; posttraining, 104.6% ± 6.1%; P = .03) and the left limb (pretraining, 96.9% ± 10.1%; posttraining, 103.4% ± 8.0%; P = .04). The control group had no change on the SEBT composite score for the right (pretraining, 95.7% ± 5.2%; posttraining, 94.4% ± 5.2%; P = .15) or the left (97.4% ± 7.2%; 93.6% ± 5.0%; P = .09) limb. Further analysis identified significant improvement for the SEBT in the posterolateral direction on both the right (P = .008) and left (P = .040) limb and the posteromedial direction of the left limb (P = .028) in the experimental group.
Female soccer players demonstrated an improved performance on the SEBT after NMTP that focused on core stability and lower extremity strength.
对照队列重复测量实验设计。
确定以核心稳定性和下肢力量为重点的神经肌肉训练计划（NMTP）是否会影响星状偏移平衡测试（SEBT）的表现。我们假设 NMTP 将改善实验组的 SEBT 表现，并且两组之间不会出现侧间差异。
SEBT 是一种功能性筛选工具，用于评估动态稳定性、监测康复进展、评估受伤后的缺陷以及识别下肢受伤风险较高的运动员。SEBT 需要下肢协调性、平衡、灵活性和力量。
20 名未受伤的女性足球运动员（实验组 13 名，对照组 7 名）参加了研究。球员们作为一个团队一起训练，因此组分配不是随机的。在实验组进行 8 周 NMTP 前后以及对照组进行 8 周无 NMTP 前后进行 SEBT。采用 3 因素混合模型方差分析来确定组（实验组与对照组）、训练（训练前与训练后）和肢体（右侧与左侧）的影响。
在参加 NMTP 后，受试者在右侧肢体（训练前，96.4%±11.7%；训练后，104.6%±6.1%；P=0.03）和左侧肢体（训练前，96.9%±10.1%；训练后，103.4%±8.0%；P=0.04）的 SEBT 综合评分上有显著提高。对照组在右侧（训练前，95.7%±5.2%；训练后，94.4%±5.2%；P=0.15）或左侧（97.4%±7.2%；93.6%±5.0%；P=0.09）肢体的 SEBT 综合评分上没有变化。进一步分析表明，实验组在右侧（P=0.008）和左侧（P=0.040）肢体的后外侧方向以及左侧肢体的后内侧方向的 SEBT 有显著改善（P=0.028）。
女性足球运动员在以核心稳定性和下肢力量为重点的 NMTP 后，在 SEBT 上的表现有所提高。
