背景：跳跃测试是功能性测试，据报道需要力量、力量和姿势稳定性来完成。三跳距离（THD）测试测量这些特征的程度相对未知。目的：确定THD在多大程度上预测运动员在力量、力量和平衡方面的临床表现。设计：受试者内相关研究。设置：以工作站为基础，对运动员进行季前筛选。患者或其他参与者：40名全国大学体育协会I-AA区男女足球学生运动员（女20人，男20人，年龄= 20.0 +/- 1.4岁，身高= 172.8 +/- 9.2 cm，体重= 71.9 +/- 8.9 kg）。干预：作为运动员季前赛综合筛选的一部分，参与者完成了平衡误差评分系统（BESS）测试，三次THD和垂直跳跃，各重复五次同心圆等速股四头肌和腘绳肌力量测试，分别为60度/秒和180度/秒。双变量相关性和线性回归分析确定了THD （cm）预测每种力量、力量和平衡测量的程度。主要观察指标：最大垂直跳跃高度（cm）、BESS总误差评分，以及分别在60度/秒和180度/秒时的股四头肌（60度）、股四头肌（180度）和腿筋（60度）、腿筋（180度）等速最大峰值扭矩（Nm）。结果：三跳距离是垂直起跳高度的重要预测因子，解释了69.5%的方差（P < 0.01）。THD对Ham（60）、Ham180（55.5%）、Quad(60) （P < 0.01）和Quad(180)（58.8%）方差的预测率分别为56.7% （P < 0.01）、55.5% （P < 0.01）、49.0% （P < 0.01）和58.8% （P < 0.01）。没有注意到THD和BESS评分之间的关系。结论：三跳距离是预测运动员下肢力量和力量的有效临床指标。虽然THD不是静态平衡的预测因子，但需要进一步研究其与更多动态平衡测试的关系。
Context: Hop tests are functional tests that reportedly require strength, power, and postural stability to perform. The extent to which a triple-hop distance (THD) test measures each of these characteristics is relatively unknown.Objective: To determine the extent to which the THD predicts performance on clinical measures of power, strength, and balance in athletic individuals.Design: Within-subjects correlational study.Setting: Station-based, preseason screening of athletes.Patients or Other Participants: Forty National Collegiate Athletic Association Division I-AA men's and women's soccer student-athletes (20 women, 20 men; age = 20.0 +/- 1.4 years, height = 172.8 +/- 9.2 cm, mass = 71.9 +/- 8.9 kg).Intervention(s): As part of a comprehensive preseason screening of athletes, participants completed the Balance Error Scoring System (BESS) test, 3 trials each of the THD and vertical jump, and 5 repetitions each of concentric isokinetic quadriceps and hamstrings strength testing at 60 degrees/s and 180 degrees/s. Bivariate correlations and linear regression analyses determined the extent to which THD (cm) predicted each of the strength, power, and balance measures.Main Outcome Measure(s): Maximal vertical jump height (cm), total BESS error scores, and quadriceps (Quad(60), Quad(180)) and hamstrings (Ham(60), Ham(180)) isokinetic maximum peak torque (Nm) at 60 degrees/s and 180 degrees/s, respectively.Results: Triple-hop distance was a strong predictor of vertical jump height, explaining 69.5% of the variance (P < .01). THD also predicted 56.7% of the variance in Ham(60) (P < .01), 55.5% of the variance in Ham180 (P < .01), 49.0% of the variance in Quad(60) (P < .01), and 58.8% of the variance in Quad(180) (P < .01). No relationships between THD and BESS scores were noted.Conclusions: Triple-hop distance is a useful clinical test to predict an athlete's lower extremity strength and power. Although THD was not a predictor of static balance, further research is needed to examine its relationship with more dynamic balance tests.
