Abstract
The evolution of phosphometabolites was determined in the abdominal muscle of a crustacean Palaemon serratus during intermittent electrical stimulation at 1, 2 and 4 Hz and during natural escape behavior. The changes in AMP, IMP, phosphomonoesters, adenylate energy charge and ATP/ADP ratio were not affected by the frequency of electrical stimulation. On the contrary, changes in ATP, ADP and sum of adenylates depended on the stimulation protocol: degradation of ATP and accumulation of ADP were not significantly different after electrical stimulation at 2 and 4 Hz as compared to manual stimulation, but differed from the 1 Hz stimulation protocol values. The sum of adenylates decreased similarly after 2 and 4 Hz stimulation and manual protocols. The different exercise protocols did not produce any changes in AMP and IMP accumulation, ATP/ADP ratio and A.E.C. After manual stimulation, the phosphomonoester and phosphoarginine concentrations were similar to the variations observed in the all electrical stimulation protocols, while the Pi levels were similar to the variations observed in the 4 Hz stimulation protocol only. The NMR index decrease was significantly higher after the manual and 4 Hz stimulation protocols.
