Effects of physical exertion on task performance in modern manufacturing: a taxonomy, a review, and a model

Article Abstract:

Physical exertion in flexible manufacturing operations improves several cognitive aspects but it is also detrimental to other mental functions. The multi-faceted aspects that affect the relationship between physical exertion and mental skills have produced varied conclusions on the subject. Physical exertion has no effect on spatial and symbolic memory capabilities and low to moderate exertion improves the speed of mental analysis that involves information processing and reasoning abilities.

The effects of whole-body restriction on task performance

Article Abstract:

This article discusses the results of a study to determine the effects of cognitive task performance in restricted spaces. The authors maintain that the more restricted the space in which an operator had to work the more he/she was affected psychologically and physiologically, and conclude that a relationship exists between restricted space, physical stress, and the operators response.
