title: [Effects of preliminary loading on dynamic strength of the spine].
abstract: The purpose of this work was to evaluate early and delayed effects of static mechanical loading of the spine on human tolerance to the ejection g-loads. Experiments with spine segments showed that static pre-loading equivalent to aerobatic accelerations of 8-10 units leads to relative strengthening of vertebra with low tolerance of the longitudinal shock load. Effect of aerobatic accelerations of 5, 6, 7, and 8 units on ejection g-load tolerance was theoretically evaluated.
