An example of a magnetic resonance image of the right foot of a runner and a cyclist. (a) This image displays the maximum area of the gluteus maximus (GM) muscle obtained from the analysis. (b–d) These images display magnetic resonance images of each part of the thigh (b 70%, c 50%, d 30% of the distal thigh length). SM semimembranosus, ST semitendinosus, BFlh biceps femoris long head, BFsh biceps femoris short head.
