    Forced swimming has also been used as a rat model to replicate CFS. Here's another discussion of a study using rats:

    See what came up on a search of PubMed:

    A Chinese herbal decoction, Danggui Buxue Tang, improves chronic fatigue syndrome induced by food restriction and forced swimming in rats.

    Astragalus membranaceus flavonoids (AMF) ameliorate chronic fatigue syndrome induced by food intake restriction plus forced swimming.

    Effect of manual acupuncture stimulation of "Baihui" (GV 20), etc. on serum IFN-gamma and IL-4 contents in rats with chronic fatigue syndrome

    Effect of acupuncture intervention on learning-memory ability and cerebral superoxide dismutase activity and malonaldehyde concentration in chronic fatigue syndrome rats

    Effect of natural and synthetic antioxidants in a mouse model of chronic fatigue syndrome

    At least they now have a model for giving acupuncture to over-exercised rats. At least it sounds sciencey.

    Exactly: that army training was surely 100 times more intense than what the rats got.

    Pretty cool job I must say, far beats cubicle drone camp.

    The forced swim test is used to see if rats are depressed. You plop them into a deep pool of water and time how long it takes them to give up.

    Needless to say, there are a lot of problems with this test.

    This model does seem bad. But I can't dismiss it entirely since it yielded a sphingolipid result. Perhaps it manages to replicate some of the important features of CFS? After all, that's all a model is: a set of useful features. I'd want to know more.

    As for making a more plausible model. It might be interesting to get rats, exercise them hard then hit them with a virus and see if a proportion never quite recover. That is an experiment I'd like to see.

    Also, a noninvasive test, such as a urine test is of course better than blood, if it works, and applied to CFS.
    An objective measure of fatigue, even if it wasn't CFS fatigue in urine would perhaps be useful as an objective measurement for trials, or even home monitoring.

    Yes, down to the choice of rock music.
