Dennis. This is really a topic for professionals in the medical disciplines. My personal experience is that sleeplessness will  lead faster to fatigue than lack of exercise. 

Harold,

Good points!!

Dear Harold,

I disagree with you that this topic is only for professionals in medical disciplines.  The fact is that the question requires expertise/ experience across disciplines.  You are correct that pulmonary specialists do most of the research on "sleep", and that cardiovascular/physiologic/training experts do most of the research on "exercise".  However, until studies are done which actually examine "sleep" and "exercise" at the same time by cross-discipline teams, there will be no scientific answer to this question.  The study of "exercise" is already cross-discipline much more so than the study of "sleep".  Therefore there is a need for discussion in terms of how questions such as this will be answered in the future.

From another perspective, one could argue that today's sleep research may have shifted beyond the physician-domain of neurologists to that of the non-physician neuroscientist so that the neurologists, neuroscientists, and pulmonary experts are interested in "sleep" research.  But what seems to be needed are a comibinator effort by "sleep" and "exercise" domain experts to answer a host of forthcoming questions about the balance of sleep and exercise.

I think the sleeping is important.
