Abstract Warming up before physical activity is a stage of transition between rest
and effort, necessary to progressively move the joints, muscles, cardio-respiratory
system, and of course on the psyche. Over the last decade, numerous studies have
postulated that the whole-body vibration (WBV) exercise, for short periods of time,
could be used as a warm-up procedure. In this paper, it is looking at the dynamic
behavior of a viscoelastic model of posterior lower limbs muscle, an analysis of how
the energy dissipation takes place based on the model used, as well as the increase
in the limbs skin temperature thereof. Harmonic-type vibrations are generated by
a Power Plate that moves in a precisely controlled manner, producing comfortable
vibratory stimulus, constantly changed when passing from one motion to the next.
For temperature measurement of skin, a forward-looking infrared camera (FLIR)
also called thermal imaging camera or infrared thermograph is used. The temperature variation according to the frequency, amplitude and vibration exposure time is
analyzed.
