[Influence of an ergometer load after intravenous lipofundin infusion on the behaviour of blood glucose, lactate, amino acid nitrogen and the free fatty acids (author's transl)].
In males aged from 19 to 21 years the influence of a bicycle ergometer load in the behaviour of blood glucose, lactate, amino acid nitrogen and the free fatty acids was examined. After determination of PWC120 20 subjects were loaded over 10 minutes in accordance with the value determined (group I). A second group (n = 15) was equally loaded after an intravenous infusion of 20-percent lipofundin. The subjects were given 2.5 ml per kg body weight (group II). The ergometer load of 10 minutes took place in the manner described above and was started 5 minutes after the end of the infusion. From the latter group 8 subjects (group III) were once again infused with lipofundin without subsequent physical stress. For determination of the parameters FFS, glucose, lactate and amino acid nitrogen venous blood was extracted at the time 0 minutes, immediately after the end of the lipofundin infusion of 20 minutes, after the end of the physical activity and 15, 30 and 60 minutes after the end of the ergometer load. The FFS rise was highest in group III, while in group II it was lower. During the load test the glucose concentrations rose in group I and were even during the reco very phase higher than in the two other groups. The amino acid nitrogen decrease in group II, but still more in group III. An increase took place in group I. The lactate rose in group II was significantly less than in group I (p less than 0.05). The results suggest a reduced utilization of glucose due to experimental increase of the FFS levels and a higher utilization of other energetic substrates.
