The current study involves a prospective interventional study that primarily intends to compare foot joint loadings of participants with chronic ankle instability (CAI) with those of subjects who recovered after an ankle sprain (LAS copers) and healthy controls during running and more challenging tasks. This study further aims to explore the impact of foot muscle properties and fatigue on the same biomechanical outcomes. Therefore, the investigators will recruit 72 participants (24 per group) aged from 18 to 44 years. Each of them will come only once to the CMAL laboratory (UZ Leuven, Pellenberg).
