I have observed this seemingly purely subjective "wall of effort" myself. It did not affect my physical performance in the lift. Since reading and posting on the forums, as well as speaking to my friends and wife who have started lifting with me, it seems I am far from being alone in experiencing this.
The question I have is... is this related to RPE (something I believe, in my limited knowledge and experience, to be ancillary at best in regards to coaching/training/programming at best) or is it something else entirely?
Is the problem entirely psychological? A mental construct formed subconsciously by intimidation of a number or the volume of black plates on a bar? Or is it caused by a previously undetermined physiological effect? Pressure on fluid bearing systems (circulatory/nervous or abdominal cavity)? Intra-thoracic pressure? Neural feedback through the CNS as the body experiences tension and/or compression?
If any one has any good resources, or even personal experience of the empirical, theoretical or otherwise, I would greatly appreciate being pointed in the right direction.
