  • Vibration Exercise training and signal changes

    A colleague and I have been researching the effect of vibration training
    on neuromuscular output (EMG and joint moments).

    When vibration is applied to the body, for example through the feet when
    someone stands on a vibrating platform, the vibration signal travels
    through the body from the feet to the head. Previous research has
    clearly shown that the vibration signal (amplitude and frequency) is
    attenuated as it travels through the body by both muscle activity (Nigg
    and Liu, 1999) and the viscoelastic nature of biological tissues (Fung,

    We are interested in knowing if the vibration signal changes in any
    other way as it travels through the body. **Do you know, for example, if
    the signal becomes more noisy the more tissues it travels through, i.e
    as it travels through the foot, through the lower leg, through the upper
    leg etc?** Has anyone undertaken research that has addressed this
    specific question, or is aware of any such research? We are interested
    in this because the muscle spindle gamma gain (often inappropriately
    referred to as muscle spindle sensitivity) is affected more by a noisy
    vibration signal than a 'clean' vibration signal (Cordo et al. 1996,
    Nature 383 p769-770).
