BACKGROUND
The Single Leg Bridge Test (SLBT) is commonly described as a measure of 'hamstring endurance'. Nevertheless, the relationship between the SLBT score and isolated hamstring endurance remains uncertain.
PURPOSE
This study aimed to investigate the correlation between SLBT scores and isolated hamstring endurance in healthy men. Additionally, the study aimed to assess the correlation between the limb symmetry index obtained from the SLBT and hamstring endurance test results.
DESIGN
Cross-sectional study.
METHODS
Forty healthy and physically active men were evaluated at the research laboratory on two separate occasions, with a minimum interval of 48 hours between visits. During each visit, participants performed either the single-leg balance test (SLBT) or the hamstring endurance test on an isokinetic dynamometer, which involved 30 concentric knee flexion repetitions performed at maximum intensity, with an angular velocity of 120°/s and a range of motion of 90°. Correlations were analyzed between SLBT scores and hamstring fatigue indexes provided by peak torque and work outcomes.
RESULTS
The SLBT score (27±7 reps) demonstrated no significant correlation with isolated hamstring endurance, as measured by isokinetic peak torque (52±9%; p=0.737, r=-0.038) or work (57±9%; p=0.489, r=0.078). Likewise, the limb symmetry index obtained from the SLBT (99±12%) did not significantly correlate with index from the hamstring endurance test: peak torque (107±26%; p=0.540, r=-0.100) and work (102±18%; p=0.849, r=0.031).
CONCLUSION
The SLBT does not appear to be a suitable tool for measuring isolated hamstring endurance in healthy men.
LEVEL OF EVIDENCE
背景
单腿桥测试（SLBT）通常被描述为一种“腘绳肌耐力”的测量方法。然而，SLBT分数与孤立的腘绳肌耐力之间的关系仍不确定。
目的
本研究旨在调查健康男性中SLBT分数与孤立的腘绳肌耐力之间的相关性。此外，该研究旨在评估从SLBT获得的肢体对称指数与腘绳肌耐力测试结果之间的相关性。
设计
横断面研究。
方法
40名健康且身体活跃的男性在研究实验室分两次进行评估，两次评估之间的间隔至少为48小时。每次评估时，参与者在等速测力计上进行单腿平衡测试（SLBT）或腘绳肌耐力测试，其中包括以最大强度进行30次向心膝关节屈曲重复动作，角速度为120°/秒，运动范围为90°。分析SLBT分数与由峰值扭矩和工作结果提供的腘绳肌疲劳指数之间的相关性。
结果
SLBT分数（27±7次重复）与通过等速峰值扭矩（52±9%；p = 0.737，r = -0.038）或工作（57±9%；p = 0.489，r = 0.078）测量的孤立腘绳肌耐力无显著相关性。同样，从SLBT获得的肢体对称指数（99±12%）与腘绳肌耐力测试的指数也无显著相关性：峰值扭矩（107±26%；p = 0.540，r = -0.100）和工作（102±18%；p = 0.849，r = 0.031）。
结论
SLBT似乎不是测量健康男性孤立腘绳肌耐力的合适工具。
证据水平
