✦ Synopsis

For the further clarification of helicopter pilot's spinal troubles caused by vibration the muscular absorption was examined with the help of animal experiments. On a swinging-table acceleration values were measured in Pirbright cavies; at first this was done under a defence reaction of the muscles, and in second experiment under maximum muscular relaxation. In the tense animal the resonance occurring at 5 Hz was almost completely absorbed, whereas in the relaxed animal a clear resonance--curve could be developed at 5 Hz. On the other hand vibration at a higher frequency up to 15 Hz were to an increasing extent better absorbed in the relaxed animal than in animal with a muscular defence reaction. For this reason the protective function of a not fatigued musculature for the defence of especially badly tolerated resonance vibrations is being discussed.
