Volleyball players have a high risk of injury in the lower limbs as a consequence of the specific characteristics of the sport, such as repetitive jumps and falls. The objective of the present study was to evaluate the effects of a multidisciplinary injury prevention program on lower limb stability in young volleyball players.
The experimental design was a non-randomized controlled trial. All the measurements were performed in a standardized room in a sports center. Twenty-six young male volleyball players (mean age: 15.39±1.16 years), divided into experimental (N.=15) and control groups (N.=11) participated in this study. The experimental group performed an 8-week prevention program including lower limb strength and plyometric training, and joint and core stability. The Y-Balance and force platform landing tests were carried out as the pre- and post-tests.
The main outcome measures were the injuries history, distance and difference reached in anterior, post-lateral and post-medial axis of the Y-Balance test, and the force produced on the z, x, and y axis after landing. Differences were found between groups and measurements in all the variables of the Y-Balance test, except in the frontal axis for the dominant leg and for the differences between legs (P=0.039-0.001); and in the ground reaction forces (z axis) (P=0.040), the x axis (P=0.014) and the dynamic postural stability index (P=0.025) of the lateral jump with the non-dominant leg.
An 8-week prevention program seems to improve the lower limb stability in young volleyball players.
排球运动员由于运动的特殊特点，如反复跳跃和摔倒，下肢受伤的风险较高。本研究的目的是评估多学科损伤预防计划对年轻排球运动员下肢稳定性的影响。
实验设计为非随机对照试验。所有测量均在运动中心的标准化房间内进行。共有 26 名年轻男性排球运动员（平均年龄：15.39±1.16 岁）参与了这项研究，分为实验组（N.=15）和对照组（N.=11）。实验组进行了 8 周的预防计划，包括下肢力量和增强式训练以及关节和核心稳定性训练。在预测试和后测试中进行了 Y 平衡和力台着陆测试。
主要的结果指标是受伤史、Y 平衡测试前、后外轴和后内轴的距离和差异，以及着陆后 z、x 和 y 轴上的力。除了优势腿的正面轴和两腿之间的差异（P=0.039-0.001）以及地面反作用力（z 轴）（P=0.040）、x 轴（P=0.014）和非优势腿侧向跳跃的动态姿势稳定指数（P=0.025）外，在 Y 平衡测试的所有变量以及力台着陆测试中，实验组和对照组之间均存在差异。
8 周的预防计划似乎可以提高年轻排球运动员的下肢稳定性。
