For the first time, the split-unit experimental design was used in simulating free muscle transplantation by microneurovascular anastomoses on the rectus femoris of rabbits, and 12 functional indexes of contractile properties and the correlation between these indexes were analyzed with a microcomputer. The results showed that the maximum tetanic tension (TET) of grafted muscle would not return to normal level in the same animal until 1 year after operation (P>0.05), and, in our opinion,in view of tension balance between two sides, this was also the optimal time to appreciate the muscle function. It was found that the fatigue rate (FR) in each group was less than 25%, without any significant difference compared with that in the normal control side (F<F0.05, P>0.05). This was the functional evidence for the finding that the constituent ratio of 3 types of muscle fibers did not change in our study series. Therefore, the main character of fast contraction of the whole grafted muscles remained the same. There was a positive correlation between FR and TeT (r>r0.01), i.e. whenever TeT increased by 1 N, FR increased 0.12%.
