Effect of kinematics on ground reaction force during single-leg jump landing in children: a causal decomposition approach in jumpers and non-jumpers

Popis výsledku v původním jazyce

Background: The interaction between joint kinematics and kinetics is usuallyassessed by linear correlation analysis, which does not imply causality.Understanding the causal links between these variables may help develop landinginterventions to improve technique and create joint-specific strengthening programsto reduce reaction forces and injury risk.Objective: Therefore, the aim of this study was to analyze the causal interactionbetween lower limb sagittal kinematics and vertical ground reaction force (VGRF)during single-leg jump landing in children who are jumpers (volleyball andgymnastics) and non-jumpers, using the causal empirical decomposition method.Our hypothesis is that children who participate in jumping sports, compared to thosewho do not, employ a different joint strategy to regulate ground reaction forcesduring landing, particularly at the ankle level.Methods: Two groups were compared: the jumpers group (n = 14) and thenon-jumpers (control group, n = 11). The causal interaction between sagittalkinematics and VGRF was assessed using ensemble empirical mode decomposition(EEMD) and time series instantaneous phase dependence in bi-directional causality.The relative causal strength (RCS) between the time series was quantified as therelative ratio of absolute cause strength between kinematics and VGRF.Results: A significant interaction between joint and group was found for RCS(p = 0.035, η2p = 0.14). The post-hoc analysis showed the jumpers group had higherankle-to-VGRF RCS than the control group (p = 0.017, d = 1.03), while in the controlgroup the hip-to-VGRF RCS was higher than the ankle-to-VGRF RCS (p = 0.004,d = 0.91).Conclusion: Based on the causal decomposition approach, our results indicate thatpracticing jumping sports increases the causal effect of ankle kinematics on groundreaction forces in children. While non-jumper children rely more on the hip tomodulate reaction forces, jumper children differ from non-jumpers by their greater use of the ankle joint. These findings could be used to develop specific trainingprograms to improve landing techniques according to practice level, potentiallyhelping to reduce the risk of injury in both athletes and non-athletes.
