摘要

Poor landing stability, particularly during single leg landing (SLL) tasks, is associated with non-contact lower extremity injuries. This study investigated the correlation between isometric hip muscle strength ratio and landing stability. Twenty male athletes volunteered to participate in this study. Their maximal isometric hip muscle strength was measured using a hand-held dynamometer (HHD) and expressed as muscle torque. Additionally, landing stability was evaluated based on the Dynamic Postural Stability Index (DPSI) and Time to Stabilization (TTS) during the SLL task. Pearson correlations were calculated to examine the relationship between isometric hip muscle strength and landing stability. There was no statistically significant correlation between isometric hip strength and landing stability (p > .05). Although moderate correlation coefficients were observed between DPSI and both hip abduction and external rotation strength, these associations did not reach statistical significance (p = .087) as well as isometric hip external rotation strength (p = .093), neither correlation reached statistical significance. The results indicate that isometric hip muscle strength alone may not be a critical factor in landing stability during SLL tasks for recreational male athletes. Further research involving larger and more diverse samples is necessary to gain a deeper understanding of the role of hip strength in landing stability, injury prevention, and performance enhancement.
