[Change in certain indices of the muscle tissue energy metabolism of rats depending on their initial level under the action of vibration].

The response of isolated muscle tissue of white rats to low-frequency vibration has been studied. It was shown on single individuals that a negative correlation exists between the values of changes in respiration intensity, creatinephosphate, and lactic acid contents, and the initial lewel of these indices. Such individual response of muscles to vibration is a non-specific cellular reaction to injury. Notwithstanding the changes of these indices in single individuals, the average populational level of these indices remains unchanged. Hence, the average level is insufficient for the characteristics of cellular reaction.
