Tissue vibration in prolonged running.

The impact force in heel-toe running initiates vibrations of soft-tissue compartments of the leg that are heavily dampened by muscle activity. ….Relative to heel-strike, the maximum vibration intensity occurred significantly later in the fatigued condition. Thus, the protective mechanism of muscle tuning seems to be reduced in a fatigued muscle and the risk of potential harm to the tissue may increase.
