| Abstract |
1. In the tail muscles of Crangon crangon metabolite concentrations were measured after different periods of escape swimming and subsequent recovery. 2. Tail flipping results in a dramatic breakdown of phosphoarginine, but only little lactate is formed. As the phosphagen is depleted rapidly, the energy charge decreases and fatigue sets in. 3. During recovery the ATP level is restored within a few minutes, phosphagen is replenished after 30 min. Large quantities of lactate accumulate which disappear very slowly. 4. In the haemolymph lactate increases only slightly. |
