The Impact of Landing Complexity and Knee Taping on Stability: A Continuous Kinetics and Kinematics Analysis

Landing biomechanics are strongly influenced by task complexity, yet the combine effects of different landing demands and taping on stability, kinetics, and kinematics remain unclear. Nineteen female athletes performed 40 cm drop landings (DL), drop jump landings (DJL), and countermovement jumps (CMJ) under four knee taping conditions: no tape (NT), rigid tape (RT), dynamic tape (DT), and kinesio tape (KT). Stability indices were compared across tasks and taping conditions. Continuous landing-phase biomechanics were analysed using SPM1d repeated measures ANOVA (<i>p</i> < 0.05). SPM1d revealed significant GRF differences between landing tasks (0-3%, <i>p</i> = 0.026; 15-25%, <i>p</i> < 0.001), with DT (<i>p</i> = 0.02) and KT (<i>p</i> = 0.03) reducing peak landing forces in the DJL compared to DL. The DL showed greater biomechanical stability overall, with better dynamic postural stability index (DPSI) across all taping conditions. However, TTS was significantly shorter in the DJL than the DL in RT (<i>p</i> = 0.005), DT and KT (<i>p</i> = 0.037). Significant joint kinematic differences were found between tasks and taping, particularly at the ankle, knee, and hip. Landing complexity influences joint loading and stability. Knee taping may attenuate impact forces and improve stabilisation during complex tasks, suggesting a potential role in enhancing movement efficiency and supporting injury-prevention.
