Magnetic resonance images showing thigh muscles (mid-thigh level) of more-affected (R) and less-affected (L) limbs of individual with stroke before (PRE) and after (POST) 12 weeks of ECC-overload flywheel RE training. Quadriceps femoris muscles denoted by numbers are: 1 m. rectus femoris, 2 m. vastus lateralis, 3 m. vastus intermedius, 4 m. vastus medialis. In this particular individual, m. quadriceps femoris volume of more-affected, trained limb increased by 11.8 %
