Domestic trampolines are a globally popular recreational activity for children, however this comes with a potentially increased risk of lower limb strains. The aim of this research was to determine if trampolines of differing stiffness influence lower limb kinematics in children. Fourteen participants grouped based on age; 5-7 and 9-11 years old, each performed twenty bounces on three different trampolines of varying stiffness. Lower limb kinematics were analysed across the ten middle bounces for each trampoline. Findings demonstrated no significant interaction effects across any hip, knee, ankle or foot kinematic variables across the trampolines within both age groups. There were also no significant differences in performance variables across the three trampolines. This study suggests that children do not appear to alter lower limb kinematics in adapting to different trampoline stiffness's.
