Can two-dimensional measured peak sagittal plane excursions during drop vertical jumps help identify three-dimensional measured joint moments?

摘要: Abstract Background Less optimal sagittal plane movement patterns are believed to increase knee injury risk in female athletes. To facilitate clinical screening with a user-friendly method, the purpose of present study was examine temporal relationships between two-dimensional measured kinematics and three-dimensional joint moments during double-leg drop vertical jump (DVJ) single-leg DVJ (SLDVJ). Methods Fifty injury-free athletes were tested. Maximal excursions hip flexion, flexion ankle dorsiflexion through video analysis. Three-dimensional motion ground reaction forces recorded calculate external abduction entire stance phase SLDVJ. One-dimensional statistical parametric mapping used peak kinematic variables moment profiles. Results Hip significantly related for both tests time frames corresponding highest moments, while these frames. No significant found any moments. Conclusions Two-dimensional angles at deepest landing position associated SLDVJ, amount only moment. Assessment analysis could benefit from measuring maximal more so than flexion.
