Nausea during high-resistance exercise

Yes, I realize this just sounds like the easy answer: "You're out of shape, man!"
The thing is, I'm 36, and in the best shape I've been in for most of my life. I've been cycling seriously for several years, and running for a little over a year, and I train all through the winter, so there haven't been any large gaps in my exercise.

So this has been plaguing me since December.

Last year I could hit it hard in a spin class, and have puddles of sweat on the floor when class was over, but now before I get close to that level of workout, I get waves of nausea. I've checked my heart rate when this was happening before and it was in the low 130s, which shouldn't bother me at all. It seems to be directly related to when I'm trying to generate power, during low speed but high resistance exercises. It doesn't seem to ever happen when running on the treadmill or running outside, or cycling, even if my heart rate is much higher. I do feel mildly light-headed during these occurrences, but not extreme.

Sound like anything in particular?

Thanks,

I would say one of these things. Brain is a hungry beast and likes to be given high priority so any of these could be it saying not getting enough of what it needs.

Diet - not enough available carb energy for sudden bursts
Breathing issues - not able to get enough oxygen in to the body
Increase of intensity or expectation on yourself
More scary, but less likely possible onset of diabetes

It's not your age, otherwise I'd be dead. Obviously the above is guess work based on what you have said, and could easily be way off.
 
I appreciate the ideas.

Diet- I'm at the gym after work, usually 4-5 hours after my last meal. I can try having a granola bar or something small maybe 2 hours before tomorrow and see if it makes any difference.

Breathing- This really sounds feasible to me, except that I'm breathing much more heavily during a run on the treadmill. That being said, I am much more likely to be consistent, and in rhythm when breathing hard, whereas during these heavy "power" output moments, I am more likely to let my breathing go, and then catch up with some heavy gasps, etc. Just generally sloppy there...

Intensity- The old saying "It never gets any easier, you just ____." is very true, but I've been doing this long enough to know what my abilities are. It's more like I'm giving it 60%, and then suddenly wham 103%!

Diabetes- Hope not! No history in the family. I may get a blood glucose meter and just test myself at certain times to see what the results are.

I've also read about (and experienced) digestive distress during intense exertion, because your stomach can get starved of blood while it's all pooling in your legs, but that's usually only an issue in endurance type events, like several hours in...
