    anyways it is not African tribal markings

    my guess would be an artefact of ultra fast shutter speed capturing a mechanical wave in the soft tissue surrounding the muscle

    but then this would not be seen


    another answer

    It looks like a varicose vein to me the muscle orientation in that area simply does not match that

    not sure I agree with that, pretty sure it is muscle and the lack of fat changing the view

    What's interesting is that it is occurring swing phase and both of the running pictures it looks like the rippling part is the rectus femoris part of the quadriceps. I wonder if it is related to the fact that rectus femoris crosses both hip and knee. The instant of both of those shots is at a time where the hip is flexing (rectus femoris shortening) and the knee could still be flexing (rectus femoris lengthening). Maybe the confused muscle is furrowing its brow.;)

    This could be nothing more than a ripple in the muscle at a certain frequency combined with the shutter speed on the camera - could be an artefact.
  4. It could be but the bodybuilder pic makes you question that conclusion
