Commentaries on viewpoint: perception of effort during exercise is independent of afferent feedback from skeletal muscles, heart,and lungs.

摘要

Marcora (3) correctly points to the complexity of the integrative process resulting in effort perception. Effort perception during exercise arises from the comparison of the demands from a feedfoward center that is shaped by psychological (e.g., mood, anxiety, etc.) and cognitive and contextual factors (e.g., prior experience at a given level of effort and performance setting) and from physiological, biomechanical, visual, and auditory sensory information. This information is preconsciously processed along with the affective dimension of exertion This preconscious processing selectively filters the information that rises to conscious awareness, leading to effort perception from which conscious decisions with regard to continuing exercise are made-this process is termed teleoan-ticipation (2).
