Several submax exercise tests r reliable, valid & acceptable in chronic pain, FMS or chronic fatigue

    I read this. Although the research strategy seems reasonably thorough (although they didn't check Journal of CFS, for example), involving checking 2637 abstracts, none of the 18 studies involved chronic fatigue or CFS patients.

    So not that much of interest to many/most here

    How did they determine that a test was submaximal? I've been trying to find older research on anaerobic threshold in any illness to check if anyone had previously seen the the drop in anaerobic threshold reported by two recent studies of ME/CFS. So far I keep finding papers on repeatability which would not be valid if those researchers had seen this drop in one group of patients. I've also seen papers in which researchers simply assumed an exercise challenge was subanaerobic, based on results from healthy people.

    Having seen actual data from a patient who hit anaerobic threshold at a power output of only 40 watts I have to wonder if some of the exercise challenges described here as submaximal were actually above anaerobic threshold, and into the range in which results resemble overtraining in athletes. Pushing into this range undermines desired repeatability of the test because performance will continue to decline unless the exercise challenge is reduced.

    On a more positive note, if anyone has found a proxy measurement for anaerobic threshold I would dearly like to know what it is, not least so I could regulate my own exercise to avoid setbacks.
