The recent publication entitled "Swimming Physical Training in Rats: Cardiovascular Adaptation to Exercise Training Protocols at Different Intensities " contained in the following link contains a protocol for anaerobic exercise models using lab animals:
I had read an article about the role of xanthine oxidase and anaerobic condition;
xanthine oxidase seems to be a major factor specific to high intensity anaerobic work.
Further evidence for the role of xanthine oxidase in mediating increased RONS was presented by Vina and colleagues (2000), who reported that inhibition of xanthine oxidase with allopurinol prevented exercise-induced oxidation of glutathione in both humans and rats.
on the other hand:
Radak et al. (1998) used rats to study the effect of anaerobic running on PC content in the lung.

Hi Nirmala, I agree with Rafik, the article is good guide, but remember Swimming,Treadmill and Wheel Running in Rats are considered aerobic exercises, ( progressive weight lifting is considered anaerobic, to model this situation in rats , a Japanese researcher (Tamaki T, et al, (1992) Med Sci Sports Exerc (24:881-886.) came up with an apparatus advantage of which is . quantifiable, reproducible standardised parameters of induction, then various modifications followed, please check links below for weight resistance exercises. Best wishes to you.
