Dear All,

Perhaps the following has been tried or if not would shed some light on
the O2 vs. Air debate with regard to exercise and tiredness.

Using resting heart rate as a measure of tiredness (common among athletes).

Get a subject (the more the better for stats) to exercise at a fixed
rate for say 1 hour on a bicycle using air.  get them to do this for a week
and measure there heart rate at different times of day. this should give you
an idea of how tired this level of exercise makes one.

repeat the exercise using O2 and monitor heart rate (possibly repeat with
21/79 heliox to model N2 vs He).

The whole lot could then be repeated at varying depths with varying mixes
until mix vs. depth vs. tiredness data was established.

I would have thought that using higher ppO2 would produce least tiredness
due to extra O2 supplying muscles with more 'energy' and keeping the exercise
aerobic, hence reducing anerobic stress

However, how would the N2 vs. He experiment work???

The exercise could also work by comparing anerobic exercise with aerobic!

ANY COMMENTS, Or has this already been done? Or do I get a big grant and
and start having fun.

yours Jon.
