It is always interesting to study the functionality of the muscles in real training conditions; in this period I am testing the usefulness of the ultrasound study performed during walking and running on the treadmill.

What is evident is a difference from the conventional examination in terms of shape and dimensions of the various muscle components, which work as a single entity.

In this study, I’m using a MyLab 9 ultrasound device from Esaote, with an external accessory called Probe-Fix which provides lengthy and stable fixation of the probe to the body.

In the video, you can see the quadriceps muscle study, but I’m also testing the hamstrings in the same conditions and during other physical activities, such as squatting and jumping.
