IDENTIFIERS MECHANICAL PROPERTIES axial system determined by the method TVS - TRANSFER THROUGH VIBRATION SPINE
Abstract
The study describes non-invasive Transfer Vibration through Spine (TVS) method, which measures selected mechanical properties of the axial system in various stress regimes. A pilot study was conducted at 12-year-old top gymnasts.
Data detection took place in three cycles, before and after the peak of the 3.5 hours of training and the next day after rest just before the next training session. The obtained values of selected rheological parameters, the attenuation coefficient β of the viscosity μ show the dynamics of the changes in the stress cycles.
The attenuation coefficient b from 0.626 before training dropped to 0.324 and then rose to 0.394 after rest. The viscosity coefficient μ showed a similar trend, falling from a value of 9.85 [PA.s] to 2.15 [PA.s] and then rising to 3.8 [PA.s].
