Rugby is a demanding contact sport. In light of research, poor balance, reduced jumping ability, muscle strength, and incorrect landing patterns might contribute to the increased risk of injury in athletes. Investigating the relationship between tests assessing these abilities might not only allow for the skillful programming of preventive training but also helps in assessing the risk of injury to athletes. Thus, the main purpose of this study was to investigate the relationship between dynamic balance, vertical and horizontal jumps, and jump-landings movement patterns. Thirty-one healthy amateur adolescent rugby players (age: 14.3 ± 1.6 years, height 171.4 ± 9.7 cm, body mass 80 ± 26 kg) participated in the study. Data were collected by the Y-balance Test (YBT), Counter Movement Jump (CMJ), Single Leg Hop for Distance (SLHD), and Landing Error Score System (LESS). Significant positive correlations were found between SLHD both legs (SLHDb) and YBT Composite both legs (COMb) (r = 0.51, = 0.0037) and between SLHDb and CMJ (r = 0.72, < 0.0001). A relationship was also observed between the CMJ and YBT COMb test (r = 0.51, = 0.006). Moderate positive correlations were found between the dominant legs in SLHD and the posterolateral (r = 0.40, = 0.027), posteromedial (r = 0.43, = 0.014), and composite (r = 0.48, = 0.006) directions of the YBT. These results indicate that variables that are dependent on each other can support in the assessment of injury-risk and in enhancing sports performance of young athletes.
橄榄球是一项要求很高的接触性运动。研究表明，平衡能力差、跳跃能力降低、肌肉力量不足和不正确的着陆方式可能会增加运动员受伤的风险。研究评估这些能力的测试之间的关系不仅可以帮助熟练地制定预防训练计划，还可以帮助评估运动员受伤的风险。因此，本研究的主要目的是探讨动态平衡、垂直和水平跳跃以及跳跃着陆运动模式之间的关系。31 名健康的青少年业余橄榄球运动员（年龄：14.3 ± 1.6 岁，身高 171.4 ± 9.7cm，体重 80 ± 26kg）参与了这项研究。数据通过 Y 平衡测试（YBT）、反向纵跳（CMJ）、单腿跳远距离（SLHD）和着陆错误评分系统（LESS）收集。发现双侧 SLHD（SLHDb）与双侧 YBT 综合测试（COMb）之间存在显著正相关（r = 0.51， = 0.0037），并且 SLHDb 与 CMJ 之间存在显著正相关（r = 0.72， < 0.0001）。CMJ 与 YBT COMb 测试之间也存在相关性（r = 0.51， = 0.006）。发现 SLHD 中优势腿与 YBT 的后外侧（r = 0.40， = 0.027）、后内侧（r = 0.43， = 0.014）和综合（r = 0.48， = 0.006）方向之间存在中度正相关。这些结果表明，相互依赖的变量可以支持对受伤风险的评估，并提高年轻运动员的运动表现。
