Reduced hip strength is associated with increased hip motion during running in young adult and adolescent male long-distance runners.

摘要: Study design Controlled laboratory study. Background and purpose Anterior knee pain is one of the most common running symptoms reported in literature. While exact etiology unknown, a lack hip strength suggested to contribute abnormal mechanics. The this research study was evaluate association between isokinetic 3-D kinematics. Methods 33 male high school collegiate cross country runners participated Peak abductor extensor were assessed. Each subject also completed treadmill protocol at self-selected speed (mean = 3.8 m/s). kinematic data collected 240 Hz using 10-camera motion capture system. Pearson correlation coefficients used determine relationship range (ROM) during stance phase (p Results torque inversely correlated with transverse plane ROM (r -.387, p .026) but not significantly related sagittal or frontal ROM. (r=-.462, p=.008) either peak kinematics any plane. Conclusions are associated kinematics, Levels evidence Level 3b.
