[Changes in energy metabolism in the tissues of animals subjected to the effects of constant and intermittent low frequency vibration].

The exposure of rats to 1 month continuous low-frequency vibration did not cause any changes in the brain adenylic fund and led to significant decrease in ATP content and total adenine nucleotides in the muscles of the extremities. For 3 months after the vibration there was a significant exhaustion of the brain and muscle adenylic fund. Under exposure to the interrupted vibration the state of adenine nucleotide system depended upon the duration of intervals limiting the continuous vibration effects. Under the vibration with the shortest intervals between each of the 30-minutes exposure there were no changes in the muscle and brain energy metabolism. 8- and 15-minute intervals for muscle adenine nucleotide and 8-minute interval for the brain proved to be unfavourable.
