Purpose. This study aims to examine how shoe insole cushioning can influence coordination pattern and variability in males and females during the landing phase of a jump-landing task. Methods. Twenty participants (10 male and 10 female) performed jump-landing tasks for this study, where the continuous relative phase (CRP) and the variability of CRP in foot/shank and shank/thigh couplings were determined during landing phase.Results. Women had lower CRP and CRP variability of foot/shank coupling in non-insole conditions (p<0.05). Shoe insole stiffness had no significant effect on CRP or variability in CRP (p>0.05). Conclusions. Although, females had lower coupling variability in non-insole conditions, they do have the capacity to achieve similar coordination patterns and variability as males, in soft and hard conditions. These findings suggest that with changes in the shoe insole, females can achieve similar joint coupling coordination patterns and variability compared to males under soft and stiff conditions. In addition, as per this study, changes in shoe insole stiffness may not have an impact on coordinative strategies or variability of lower extremity joints couplings during landing.
