Abstract

Background: Even though both landing stability and ankle dorsiflexion stiffness (ankle DR-stiffness) have been independently identified as risk factors associated with non-contact injuries, no study has specifically investigated the relationship between these two variables.

Methods: Twenty male recreational athletes volunteered to participate in this study. Their ankle DF-ROM based on the weight-bearing lunge test, and landing stability based on the dynamic postural stability index (DPSI) and time to stabilization (TTS) were evaluated during a single-leg landing (SLL).

Results: There was no statistically significant difference among ankle DF-ROM, ankle DF-stiffness, DPSI, and TTS during the SLL task (p > .05). Although a moderately positive relationship was observed between ankle DF-ROM and ankle DF-stiffness (p = .177; r = .354 [95% CI, -.153 to .653]) and a moderately negative relationship between ankle DF-ROM and TTS (p = .163; r = -.375 [95% CI, -.598 to .098]), these were not statistically significant.

Conclusion: The findings indicate that ankle DF-stiffness as an independent variable, does not significantly affect landing stability based on the TTS and DPSI indexes. However, its interaction with other variables, such as sex, age, and the nature of the movement task, may influence landing stability. This study area warrants further research.

单腿着地时，着地稳定性、踝关节背屈活动范围和踝关节僵硬度之间是否存在相关性？

背景：尽管着地稳定性和踝关节背屈刚度（踝关节dr -刚度）都被独立地确定为与非接触性损伤相关的危险因素，但没有研究专门调查这两个变量之间的关系。方法：20名男性休闲运动员自愿参与本研究。他们的踝关节DF-ROM基于负重弓步测试，着陆稳定性基于动态姿势稳定指数（DPSI）和稳定时间（TTS）在单腿着陆（SLL）中进行评估。结果：SLL任务中踝关节DF-ROM、踝关节df -刚度、DPSI、TTS差异无统计学意义（p < 0.05）。虽然观察到踝关节DF-ROM与踝关节df -刚度之间存在中度正相关(p = .177；r =。354 [95% ci, -。153 ~ 0.653])，踝关节DF-ROM与TTS呈中度负相关(p = 0.163；r = -。[95% ci, -。]598 ~ 0.098])，无统计学意义。结论：基于TTS和DPSI指标，踝关节df刚度作为自变量，对落地稳定性影响不显著。然而，它与其他变量的相互作用，如性别、年龄和运动任务的性质，可能会影响着陆的稳定性。这个研究领域值得进一步研究。
