I have been doing dry and pool training for a long time now, and my dry apnea performance is always significantly better than in the pool. I have tried to work out what the reason is, but nothing fully explains it.
- Posture - I am in a lying down position for both, I lie on my side for dry static. I do not do either in a sitting or standing position.
- Suit - The effect is the same in static or dynamic, and seems to have little to do with a restrictive suit.
- Fear/stress - I am not normally scared or stressed during pool training. My stress levels are about the same for both.
- Absorbing O2 through my nose - I don't normally use a noseclip for wet or dry static, but I tried dry statics with nose pinched and they were still much longer than my wet static PB.
- Cold - My performance is much worse when I am cold, but I am not always very cold during training.
The only thing I can think of that could cause the difference is the cool water on my face. If I am doing dry statics in even a slightly cool room, it has the same effect as the pool.
Maybe the dive reflex is having a negative effect?
