Hi Dastardly,
while not getting to the extrems you are describing, I do experience som efaintenss when clenaning. I would actually say the Power Clean is the only lift that has this effect.
The dizziness is really mild and lasts only a couple of seconds at the top of the lift, if that. In order to alleviate it, I have tried two things:
- breath in a bit less before the first pull. Rather than gulping as much air as possible, I simply fill myself until I'm confortably tight, but no more.
- move the bar just a fraction away from my neck after the rack. Sometimes the bar ends too close to my throat, and I can actually feel some internal pressure being relieved if I then move the bar away. The movement is minimal, but significant.
Note that during the deadlift I still aim to fille up my lungs as much as possible, but in that case I think the slower movement allows my body to adjust, and avoid dizziness.
I hope this helps.
