The role of fatigue in injury development is an important consideration for clinicians. In particular, the role of eccentric fatigue in stretch shortening cycle (SSC) activities may be linked to lower limb overuse conditions. The purpose of this study was to explore the influence of ankle plantarflexor eccentric fatigue on SSC effectiveness during a hopping task in healthy volunteers. 11 healthy volunteers (23.2 ± 6.7 years) performed a sub-maximal hopping task on a custom- built sledge system. 3D motion capture and surface EMG were utilised to measure lower limb stiffness, temporal kinematic measures and muscle timing measures at baseline and …
