Exercise Induced Muscle Damage (EIMD) is associated with
force reduction, inflammation and pain after exercise
and is often accompanied by Delayed Onset Muscle
Soreness (DOMS). In this study significant variation in
muscle stiffness, measured using Magnetic Resonance
Elastography (MRE), and force output are determined
following an eccentric exercise protocol. Subjective
pain assessment revealed significant pain increase
following damage indicating the presence of DOMS. The
rectus femoris muscle group is primarily affected with
localised oedema present on T2 weighted imaging.
