Aging, physical activity, and cognitive processing: an examination of XXXX .

Physical activity appears to attenuate the decline of cognitive function typically observed in older @entity1 and @entity1 . The @entity3493 component of the event-related potential (ERP) is particularly affected by aging and allows for basic neurobiological assessment of cognitive function. Three aspects of the @entity3493 component (i.e. latency, amplitude, and area under the curve (AUC)), elicited by an oddball task, were derived to assess cognitive function in young and older @entity1 (N=73) who were further classified as high- and low-active. The low-active elderly @entity1 exhibited larger AUC values than those observed in all other groups which were undifferentiated. That is, the high-active elderly and the young @entity1 exhibited smaller AUC values than the low-active older group. In conclusion, higher levels of physical activity in the elderly may be associated with a reduction in the neural resources allocated in response to simple cognitive challenge. This interpretation is consistent with the concept of psychomotor efficiency proposed by Hatfield and Hillman [The psychophysiology of sport: a mechanistic understanding of the psychology of superior performance. In: Singer RN, @entity15773 , Janelle CM, editors. Handbook of sport psychology. 2nd ed. New York: Wiley; 2001, p. 362-88].
